Okay,
starting
recording
so
welcome
everybody.
This
is
the
last
day
of
the
open
source,
microfactory
Steenkamp
a
great
great
session,
the
first
one
lots
of
learnings.
Of
course,
major
improvement
to
be
had,
and
we
want
to
run
this
in
many
places
so
we're
getting
prepared
to
how
to
how
can
we
actually
deliver
this
to
other
locations,
training
people
so
forth,
so
I'll
start
with
so
we
have
a
design
session
this
morning,
but
I'll
start
with.
A
A
There
it
is
so,
let's
just
go
through
that
wrap
up,
so
some
some
takeaways
like
how
you
know
minor
points
of
collaboration
or
great
points
of
collaboration,
a
few
things
I
can
point
out
to
yesterday
we
had
a
little
review.
Thank
you,
everybody
who
did
the
review
and
I'll
I'll
get
back
to
that
again
here,
but
first
of
all,
first
first
point
of
follow-up.
If
you're
interested
in
in
having
the
steam
camp
or
other
workshop
near
your
location,
we're
gathering
people,
do
we
have
mirroring
William.
Can
you
move.
B
A
B
A
So
if
you
go
to
the
first
link,
we
have
what's
known
as
a
workshop
interest
forum
and
that
is
basically
putting
people
on
a
map.
These
are
all
people
interested
in
workshops
around
their
locations.
So
if
we
find
that
there's
like
six
or
more
in
any
given
location
I'm
there,
we
can
run
a
workshop.
So
please
put
yourself
on
a
map
and
we
can
go
from
there.
So
this
is
workshops
steam
camps,
any
any
of
our
events.
There
are
remote,
definitely
wanna
get
Scott
and
Belize
on
there.
A
B
A
Belong
to
help
Hawaii,
so
that's
a
cool
thing.
The
maps
are
always
a
powerful
thing,
and
this
will.
This
also
applies
to
world
tour,
as
I
didn't
even
mention
this
here.
So
I'm
gonna
edit.
This,
and
also
also
put
yourself
on
this
for
world
tour,
because
I'm
planning
on
publishing
a
book,
September
2020
and
probably
go
for
like
three
months
or
so
go
on
the
road
recruiting
for
the
design
challenge,
as
well
as
possibly
running
workshops
during
that
time,
building
things
so
I'll
kind
of
like
Mark
Twain
did
his
world
tour
like
this?
A
C
A
I'm
also
gonna
invite
you
to
Oslo
in
it
and
a
couple
of
decades
now
Oslo
is
where
they
give
out
the
Nobel
Peace
Prize.
So
that's,
that's
not
me.
That's
that's
the
effort
so
but
invitations
to
everybody
in
the
future.
If
you're
involved
yeah
we'll
have
our
probably
sign
better,
better
swag
at
that
time,.
B
A
A
We
have
produced
some
kits
email
me
at
opps,
at
open
source,
ecology,
org,
put
yourself
on
the
wait
list
for
shipping.
The
idea
here
is
to
develop
very
clear,
Production
Engineering
for
for
producing
12
kits
in
a
single
day,
so
that
means
really
refined,
refining
the
rod,
cutting
the
the
verification
process
of
the
electronics
and
everything
else.
A
You
can
pretty
much
crank
them
out
as
a
viable
revenue
model,
so
twelve
kids
in
a
day
so
for
announcements
on
shipping
sign
up
to
OSC
mail
click
on
that,
if
you're
not
already
signed
up
for
OS
email,
open
source,
ecology,
email,
the
OSC
newsletter,
click
on
that
you'll
be
taken
to
this
very
simple
form:
we're
on
PHP
list.
You
can
add
yourself
to
the
email
list
with
that
said
with
it
with
a
kit
production
model.
The
very
explicit
goal
is
developing
at
$10,000
per
month,
half-time
business.
A
A
So
we
have
a
full
build
guide
for
that,
really
detailed,
absolutely
everything
you
need
there!
I
did
send
that
and
one
of
the
initial
emails.
But
that's
that's
the
last
version.
We
need
to
update
that
for
that
also
for
rapid
training
like
thinking
about
augmented
reality,
instructionals
and
that
that
topic
came
up
since
about
three
or
four
years
ago,
but
we
also
want
to
produce
in
that
Enterprise
in
order
to
train
people
rapidly.
We
would
want
to
do
what
the
professional
training
for
the
trades
does.
A
That's
augmented
reality
where
you
can
actually
have
superposed
information
upon
what
you're
working
with
either
with
a
cell
phone
there's
basic
applications
with
a
cell
phone
or
with
actual
VR
goggles
that
help
you
learn
all
of
that
in
a
rapid
way.
So
that's
part
of
the
development
of
that
model.
One
is
the
Production
Engineering,
there's
marketing
there
its
website,
but
first
it's
the
technology.
So
we
we
took
long
time
to
do
this,
build
I,
think
we
got
forward.
We
moved
forward
on
verifying
that
things
are
working.
A
The
biggest
one
of
the
biggest
developments
was
the
insulated
heated
bed
by
the
way,
no
other
printer
in
the
world
that
I
know
of
has
an
insulated
bed.
People
don't
care
yet
about
the
energy
efficiency
on
3d
printers,
but
we
are
saving
30
to
40
percent
of
energy
for
running
the
printer
with
the
insulated
bed.
So
we
do
have
state-of-the-art
design
using
expensive
extruders
that
are
state-of-the-art.
We
were
using
the
e3d
titan
arrow
or
some
rumor
that
said
that
the
bill
of
materials
cost
for
this
build
was
$250.
A
A
The
compare
I
would
say
comparable
printer,
like
lulzbot,
now
they're,
more
refined
and
more
elegant
still,
but
they're
selling
their
based
printers
for
like
$2,000
or
$2,500,
so
I
mean
that's
the
kind
of
market
we
were
in
or
we're
comparable
to
Prusa
or
maybe
I
made
3d,
but
those
are
more
like
a
hobby
and
education
printers.
That's
not
where
we're
at
were
we're
into
industrial
production,
so
those
kids
cost
a
thousand
and
800
respectively.
I
made
3d
is
about
a
thousand
through
seven
kits
are
800
but
so
develop
the
help
develop.
A
The
I
mean
we
talked
about
revenue,
streams
and
financial
sustainability
right
now.
The
closest
thing
on
a
plate
is
the
3d
printer.
Also
give
us
next
item,
there's
also
an
online
workshop
review
forum,
where
you
could
give
us
a
star
rating.
So,
basically,
the
similar
questions
as
before,
there's
a
workshop
feedback
forum,
which
is
relevant
for
any
workshop
and
we're
collecting
that
so
far,
we've
got
like
three
or
four
stars
as
actually
about
4
stars
right
now
for
the
different
results
of
different
workshops,
so
basically,
which
which
workshop
did
you
participate
in?
A
A
A
A
Next
item
show
up
in
Belize,
we
have
a
date
and
that
is
November
9
to
the
13
9
10
11
12
13,
a
5-day
build
of
a
micro
house
similar
to
what
we
have
a
basic
one,
12
by
12
interior
surface
14
by
14
foundation.
This
is
all
gonna,
be
CB,
stabilised,
CB,
we're
also
gonna
use
the
basket
technique,
meaning
using
reinforcing
mesh
there's.
Actually,
this
five
really
new
product,
a
fiberglass
mesh
that
you
put
on
both
sides
of
the
walls
and
cross,
tie
them
for
earthquake
resistance.
A
That's
a
state
of
art
for
earthquake
resistance,
as
opposed
to
rebar.
According
to
the
leading
CB
builders.
We're
gonna
do
that
a
very
simple
structure.
At
that
point,
we
don't
have
to
worry
about
insulation
like
here,
so
that
build
is
gonna,
be
much
easier,
relatively
low-cost
and
we're
gonna
offer
that
as
an
international
workshop
for
those
five
days
and
also
we've
got
the
second
largest
Barrier
Reef
and
north
in
the
world,
in
the
world
largest
reef
in
in
North
America.
So
there's
also
tourism
visiting
Mayan,
ruins
and
snorkeling
after
the
workshop,
which
we
can
facilitate.
A
B
A
The
big
point
about
that
is,
after
that
we're
gonna,
set
that
brick
press
up
they're
running
so
once
people
see
that
you
can
build
this
at
low
cost.
We
we
intend
to
show
well
make
the
machine
available
for
anyone
else
who
wants
to
get
access
to
low-cost
housing.
Scott
do
we
know
a
comparison
for
what
it
would
cost
to
do?
Cb
walls
to
against
their
traditional
construction,
like
with
brick,
yeah.
D
A
B
A
A
Next
item
follow
us.
You
know,
as
far
as
the
announcements,
please
sign
yourself
up
for
all
s,
email,
if
you
want
to
make
sure
you
get
the
announcements
about
this.
As
far
as
the
kind
of
structure
will
be
building
will
be
comparable
to
micro
house,
to
which
you
can
view
a
video
on
the
wiki.
As
far
as
what
that
went.
Like
a
very
small
structure
in
the
case
of
micro
house,
we
had
the
bricks
pressing
real
time
as
we
were,
laying
them
into
the
wall,
so
they
weren't
even
dried.
A
We
kind
of
settled
a
little
bit
this
time
around
we're
gonna,
pre,
press
bricks
and
they're
gonna
be
stabilized,
so
it's
gonna
be
a
one
major
improvement
on
a
brick
press,
and
that
is
the
infrastructure
for
doing
proper
ratio,
soil
mixing
with
cement.
So
you
have
blocks
that
are
resistant
to
water.
You
don't
have
to
protect
them
from
rainfall.
They
will
not
melt
like
regular
bricks
if
you
don't
stabilize
them.
Next
item
now
follow
us
en
iOS
the
workshops.
Facebook
page,
that's
the
most
regular
place
where
we
post
updates.
A
So
if
you
aren't
signed
up
to
that,
please
do
so
open
source,
ecology
workshops,
the
cover
page.
There
is
the
gasifier.
That's
the
power
cube
running
on
on
charcoal
in
one
of
our
workshops.
You
see
recent
pictures
and
everything
else
and
good
updates
related
to
OSC
workshops
and
other
training
and
events
of
open
source.
Ecology.
A
Next
item
invite
us
to
run
professional
development,
start
an
OSC
Club
in
your
school
three-day
program.
So
that
would
be
me
coming
in
a
2,000
bucks.
You
get
a
3d
printer
with
that
and
training
of
how
to
do
basic
design
and
guidance
on
starting
a
club,
so
we
can
get
plugged
in
essentially
to
the
collaborative
literacy
and
the
projects
of
OSC
William
has
started
the
first
OC
Club
in
London
Ontario.
This
would
be
a
great
force
for
development
and,
as
we
go
into
the
Aussie
incentive
challenge,
the
clubs
can
also
collaborate
on
that.
A
So
we
have
an
army
of
people
also
participating
in
a
challenge
as
part
of
that,
so
it's
2,000
bucks
for
two
teacher
pairs
or
two
librarians
or
however
you'd
like
to
do
three
three-day
intensive
professional
development.
You
can
click
on
that
on
the
micro
factory
website,
micro
factory,
that
open
source
ecology
org
further
explanation
there
for
what
that's
about
next
item
helped
us
edit
the
copy
so
so
from
part
of
the
feedback
was
that
expectation
management
needs
work.
A
Some
people
might
have
been
disappointed
as
far
as
okay
we're
promising
all
of
this,
and
that-
and
maybe
the
you
know
it's
much
rougher
here
much
more
experimental
than
people
are
used
to
help
us
edit
the
copy.
If
you
responded
that
hey
this
was
not
not
what
I
signed
up
for
or
if
this
was
not
at.
If
you
feel
this
was
inaccurate,
we've
got
the
existing
workshop
announcement.
Take
that
and
edit
it
you
know
just
either.
Send
me
an
email
or
copy
the
whole
thing
and
copy
paragraphs
and
and
add
whatever
texts
are
amended.
A
This
text
to
what
you
think
would
make
it
a
realistic,
a
more
realistic
representation.
You
always
tried
to
I
think
we.
We
always
have
some
issues
with
that
for
workshops,
we're
trying
to
describe
what
we
have
here
in
the
most
accurate
way.
But
obviously
that's
you
know
some
people
for
some
people
is
like
yeah.
This
is
some
of
what
I
expect
or
I
had
no
expectations
for
others.
It
might
be
like.
Oh
maybe
this
the
description
wasn't
accurate,
so
help
us
edit
it
if
you
so
that's
for
the
people
on
site.
A
A
So
the
idea
there
is,
you
know
each
person
that
would
do
this
would
bring
their
own
flavor
to
it
and
maybe
reduce
the
sculpt
or
put
it
make
it
go
in
other
directions,
but
as
long
as
we're
collaborating
an
open-source
real
product
design
using
large-scale
collaborative
build
methods,
OSC
part
libraries
or
the
techniques
that
we
use,
you
can
run
a
steam
camp.
So
what
I'd
like
to
invite
I
can
mentor
you,
but
you
would
own
it
and
do
the
marketing.
A
Thinking
like
if
you're
running
this
thing,
I
would
request
like
eighth
of
the
gross
something
like
that
or
if,
if
you're,
if
we're
really
spending
a
lot
of
time
with
you,
maybe
it's
like
a
50/50
deal,
but
if
you're
running
this,
because
you
have
the
motivation
and
skills
you
can
do
a
different
form
of
this,
like
perhaps
William
might
you
know
you're,
perhaps
the
most
qualified
to
do
this
right
now?
Do
a
little
revenue
share
so
now
you're
doing
this
for
your
livelihood.
That's
how
we
need
to
do
this.
D
A
Review
recordings:
the
last
item
review
the
recordings
of
the
open
source
microfactory
steam
camp
recordings.
So
we
have
pretty
much
all
that
we've
done
so
far
on
that
page.
So
if
you
to
anything
during
the
sessions
or
the
video
cut
out,
this
should
be
mostly
complete
here
and
we're
recording
right
now.
So
we're
also
capturing
this.
So
that's
about
it
any
questions
or
suggestions
on
on
what
we've
said
so
far
here
this
is
just
kind
of
points
of
entry
mm.
It's
actually
not
that
much!
It's
so
far,
12
by
12
interior
structure.
A
You
essentially
have
three
walls
set
three
times
four-foot.
We
kind
of
look
at
four
by
eight-foot
wall
sections,
three
of
those
per
side,
so
you
have
three
times
four,
which
is
twelve
and
you're
multiplying
twelve
times
200
it's
about
200
per
4
by
8
wall
sections,
so
2400
bricks.
However,
we
have
four
walls.
E
A
Not
a
double
wall
single
wall,
one
foot,
deep,
that's
2,400
bricks,
but
there's
doorways
and
three
windows,
so
minus
four.
So
it's
really
12
minus
four
or
eight
sections
times
200
1600
block.
If
we
make
the
what
the
window
units
basically
framed
modules
against
which
the
the
bricks
but
up
an
idea
for
the
framed
modules
is
also
they
can
use
as
a
block
against
which
we
can
lay
them.
A
We
found
that
it's
really
impossible
to
work
with
string
that
doesn't
scale
because
there's
too
many
people
and
people
keep
hitting
this
string
and
it
takes
time
to
arrange
the
string
and
you
have
to
go
to
a
quarter
inch
within
the
string,
because
you
can't
touch
the
string
so
we're
gonna
try
something
different
to
I
mean
if
we
get
this
work
work
flow
down,
you're
talking
about
like
we're
aiming
for
24
people.
If
you
have
six
people
on
each
side,
that
means
two
people
per
section
of
200
block
two
hours.
A
24
people
two
hours
to
get
all
the
walls
up
after
the
forms
are
in
place.
I
mean
this
is
gonna,
be
a
crazy
experience.
We're
marketing
this
as
an
experience
that
that's
the
ideal.
How
close
to
that
are
we
gonna
get,
but
we
never
got
to
our
does
down
to
two
hours
yet,
but
now
we're
gonna,
add
the
backing
of
plywood
as
well
as
we
really
have
to
do
a
better
job
on
slurry
mixing.
A
Slurry
mixing
is
actually
the
the
most
time
limiting
part,
because
people
have
to
mix
slurry
for
the
the
courses
that,
what's
between
the
bricklayers
and
we're
gonna,
have
all
the
bricks
prepared.
So
at
that
time
it's
like
we've
had
access
to
the
brick.
The
limiting
step
is
how
fast
you
can
pretty
much
lay.
The
slick
is
to
put
a
brick
into
a
wall.
It's
like
a
couple
of
seconds.
If
the
slurry
is
there,
you
essentially
put
it
on
kind
of
like
squeeze
it
down.
It's
not
like
mortar.
A
This
is
not
mortar,
where
mortar
requires
you
to
to
trowel
it
on
and
kind
of
level
it
out,
but
you
butter
it
up
and
kind
of
make
it
fit,
but
this
is
not
like
that.
It's
a
thin
slurry
slip
between
the
layers
that
goes
really
fast,
it's
faster
than
brick
laying
so
that
could
be
excellent
and
any
other
questions.
A
C
A
C
A
Any
other
questions
from
remote,
okay.
Well,
let's
continue
so
today's
topic
is
couplers.
It's
like
a
almost
like
a
boring
topic,
but
it's
a
very
important
topic.
I'll
touch
on
also
a
little
bit
of
review
on
frames,
because
the
idea
is
the
major
major
components
of
any
any
mechanical
device.
Are
a
frame,
a
motion
system
controller
like
the
universal
axis
for
motion
or
like
wheel,
drive
for
tractors,
so
kind
of
like
in
a
big
picture
of
things.
A
Let's,
let's
review
a
little
bit
of
on
that,
because
it
is
so
important
and
it's
the
the
missing
link
like
if
you
don't
know
how
to
do
a
coupler,
you
can
have
access
to
all
the
other
parts,
but
without
a
coupler,
you're
not
gonna,
be
able
to
build
something
and
the
couplers
actually
turns
out
to
be
one
of
the
the
most
tricky
things
to
get
like
right
now
we
are
basically
blocked
on
the
we
started
a
design.
We
wanted
to
build
an
solar
golf.
Golf
cart
here.
A
Power
cube
based
golf
cart,
but
we
could
not
find
the
cup
that
the
coupler
for
the
motor
so
I'll
talk
about
that.
What's
the
deal
with
that,
and
in
particular,
so
let
me
go
to
the
design
guide
and
I'll
do
that
as
a
specific
case
of
the
couplers,
when
we
get
to
that.
So
let's
talk
about
couplers
but
yeah.
Let's,
let's
actually
open
up
with
that,
because
it's
a
very
tangible
project.
We
found
some
net
nice
motors
hydraulic
motors.
So
to
be
this
would
be
a
hydraulic
system.
A
You
can
use
a
a
power
cube,
that's
run
on
electric
power
like
solar.
You
can
run
it!
That's
based
on
an
engine
because
you're
generating
you
basically
running
a
hydraulic
pump,
which
we
talked
about
you're
running
a
hydraulic
pump
to
create
high
force
and
by
using
four
wheel
motors
that
are
readily
accessible
on
surplice
Center.
A
E
A
A
Paste
it
in
the
wiki,
so
we're
designing
this
golf
cart
going
to
the
presentation
we
got
this
far,
so
our
simple
CAD
model
with
a
power
cube-
and
you
see
the
hydraulic
motors
there,
so
we
did
a
couple
of
design
sprints.
We
got
to
this
point.
It's
a
frame
and
a
frame
there's
a
power
cube
inside
this
larger
structure.
Those
small
small
things
here
are
your
hydraulic
motors.
E
A
C
A
We
go
through
the
power
cube.
We've
got
that
nailed.
We
could
build
that
in
a
second
we're
talking
about
you
know
what
are
the
options?
How
do
you
do
that?
Looking
at
industry
standards
for
a
golf
cart
for
the
Heights
and
widths
and
lengths,
then
you
get
to
the
B
ome
of
the
motor.
So
we
identified
the
motor
from
surplice
Center.
We
actually
catted
it
up.
Basically
extruding
the
2d
images
into
3d
using
freecad,
which
is
something
you
can
do.
A
You
can
import
an
image
into
freecad
and
then
draw
over
that
and
you
just
extrude
that
so
we
got
the
exact
geometry.
So
this
was
a
good
thing
where
you
would
take
that
image
scale
that
up
accordingly,
so
it's
actually
to
real
size
like
you're
like
we
got
three
point:
five
eight
inches
there.
Well,
actually
we
have
to
scale
that
image
there,
because
I'm
seeing
that
that
length
of
that
distance.
A
A
B
A
A
You
know,
that's
not
so
great,
that's
enough
for
a
golf
cart,
150
bucks.
But
then
you
look
at
the
detail.
A
tapered
shaft
1
inch
find
me
a
coupler
for
that
we
couldn't
so
that
means
we'd
have
to
fabricate
it.
You'd
have
to
go
to
a
lathe,
then
do
a
taper
on
a
lathe
and
then
put
an
inner
key
way
in
that
just
kind
of
beyond
us
right
now,
so
we're
blocked
at
that.
But
that's
the
importance
of
couplers.
How
do
you
do
that,
like
at
this
level
here?
A
We
could
not
find
it
off
the
shelf,
so
we
couldn't
find
it
at
surplus
center.
When
we
called
up
the
motor
manufactured
I
said:
oh,
we
don't
make
that
and
yeah,
and
you
know
a
swagger
shop
is
probably
our
best
idea.
It
so
swagger
the
local
matter,
fabric
matter,
fabric
fabricator.
He
can
probably
get
us
something
like
this,
but
it's
not
like
I'm
surplus
center,
for
example,
you
can
find
one
point.
A
If
you
look
at
the
hydraulic
motors
wheel
motors,
you
can
very
easily
find
like,
for
example,
for
the
larger
motors
say
the
largest
one
here
45
cubic
inch,
which
is
got
like
10,000
pounds
torque
these
couplers
they
have
them.
They
have
the
tapered
hubs
for
1.25
inch,
but
that
other
motors
got
a
one-inch
shaft
and
we
just
can't
get
it.
So
that's
the
importance
of
couplers.
You
got
to
know
how
to
find
a
mortifying.
I
mean
for
this.
Still.
This
is
an
open
question.
A
We
still
haven't
found
it
and
we
didn't
I
mean
we
had
some
people
look
at
it,
maybe
for
a
few
hours,
maybe
like
few
or
maybe
up
to
eight
hours
of
research
that
we
looked
at
that
just
online
but
couldn't
do
it.
We
called
up
a
couple
of
places
to
find
out
that
the
man
you
sure,
doesn't
make
this
coupler.
So
it's
this
one
of
the
one
of
these
things
where
the
industrial
system
is
pretty
broken,
broken
down
into
specialization.
A
So
one
guy
who
makes
the
motor
that
cannot
even
tell
you
how,
where
you
gonna,
get
a
coupler
for
it,
which
is
like
when
you
think
about
it.
That's
pretty
insane
you'd
think
that
would
be
readily
available.
So
let's
go
to
the
couplers
and
talk
about
a
few
basic
types
of
couplers.
So
if,
if
you
you
have
a
hydraulic
motor
like
that,
okay,
then
you're
kind
of
have
a
challenge
there.
You
can.
You
can
of
course
fabricate
it.
A
So
that's
the
case
for
the
heavy
duty,
milling
or
laving
that
we
can
do
readily
after
we
do
the
2
inch
universal
axis.
That's
the
kind
of
a
job
we
can
probably
do
and
well,
but
otherwise,
let's
see
what
the
options
are
for
types
of
couplers
so
so
easily
you
can
get
solid
couplers.
This
is
mcmaster-carr.
This
is
in
the
surplus
center
or
we
get
a
lot
of
our
stuff
for
prototyping,
so
solid
couplers
with
a
keyway
there's
two
routes
about
that
one.
A
You
can
have
a
keyway
on
a
this,
for
example,
this
coupler,
which
you
can
see
the
keyway
in
there
for
for
a
locking
key.
Otherwise,
if
you
don't
have
the
key,
the
shaft
would
spin
freely
it's
not
you
can't
just
press
it
in
and
expect
it
to
stick.
You
have
to
have
a
physical
block,
the
key
way
so
that
your
motor
drives
the
shaft
or
you
can
have
the
splines.
A
We
use
this
a
lot
actually
with
the
hydraulic
pumps,
which
are
which
we
like
to
get
hydraulic
pumps,
the
small
pumps
that
have
spline
couplers,
because
I
can
tell
you
from
experience
that
the
tiny
little
key
way
there
and
set
screw
it's
much
harder
to
do
that
than
just
inserting
that
that
motor
into
this-
and
you
don't
have
to
worry
about
a
set
screw
or
anything.
It's
all
it's
there.
It
has
a
tiny
bit
of
play
for
adjustment,
but
otherwise
you
got
to
get
it
on
straight.
A
So
that's
very
useful,
especially
when
the
shaft
is
five
eighths
inch
and
working
with
a
keyway
and
a
small
set
screw
is
one.
It's
got
to
be
accessible
in
two
I
mean
if
it
gets
loose
and
falls
out.
Your
system
fails
so
sod
couplers
are
one
way
to
go.
There's
chain.
Couplers,
we've
used
this.
We
use
this.
A
So
these
are
chains
where
you
have
two
sections
bound
by
a
double
chain,
so
this
is
40.
This
is
actually
73
horsepower
double
roller
chain.
Coupler,
that's
some
heavy
force
there,
but
chains.
Allow
you
a
little
bit
of
play
there
while
transferring
huge
torques.
So
to
give
you
an
example
of
huge
torque
transmission
on
that
we
have,
for
example,
the.
A
There
we
use
a
double
double
chain
coupler,
so
if
you
want
to
build
the
universal
rotor,
this
is
what
it
looks
like.
This
is
a
device
that
can
function
as
wheel
drive
for
a
tractor
or
another
rotor
like
we
use
two
of
these
for
a
large
trencher
wheel.
Trencher
can
use
this
as
a
rotor
for
anything
depending
on
how
fast
the
motor
that
you
attach
to
it
is.
But
let's
here's
actually
a
fool,
start
the
guide.
Here's
a
cool
fabrication
manual
for
how
you
build
the
universal
rotor,
but
part
of
it
is
the
chain
coupler.
A
So,
let's,
let's
move
on
so
you
got
big
bearings
like
2-inch.
We
can
use
this
rotor
with
2
inch
or
three
inch
bearings,
so
you
mount
it
on
a
plate.
You
mount
a
big
motor.
How
do
you
couple
the
motor?
We
use
the
double
chain
coupler,
so
we
put
this
so
you
put
the
hub
on
it,
put
an
interim
plate
and
this
these
huge
chains.
A
This
can
withstand
withstand
tens
of
thousands
of
pounds
of
force
without
shredding.
So
it's
an
effective
way
to
do
low,
torque,
high
torque,
very
low
speed,
high
torque
activity.
So
then,
you
put
your
not
putting
the
the
link
into
that
lock
lock
the
link,
but
this
is
like
a
super
heavy
duty
coupler
here
we
bandsaw
the
shafts,
put
them
in
kind
of
ground
them
up
here
we
milled
a
keyway.
A
A
It
can
be
a
little
tricky
to
get
that
on.
If
you,
you
know,
the
clamp
collars
come
right
off,
whereas
this
key
you're
gonna
have
a
hard
time
fighting
it
to
get
it
out,
so
putting
that
together,
welding
that
up
and
so
forth,
application
of
a
very
heavy-duty
coupler
system.
Other
types
of
couplers,
flexible,
lovejoy
couplers
like
these,
so
these
are
two
half
two
halves
with
the
spider
in
between
the
spiders,
rubber
and
the
metal
and
so
gives
you
a
flexible
connection
that
can
be
misaligned,
it's
much
more
tolerant
for
misalignment.
A
So
things
like
that
these
draw
couplings,
you
need
two
of
these.
They
can
have
whatever
diameter
on
one
part
and
the
other.
So
you
can
couple
to
different
diameter
shafts.
You
have
this
rubber
spider.
The
only
consideration-
and
this
is
if,
if
it's
too
hot,
the
spider
is
gonna
melt
away.
So,
for
example,
we
use
this
on
early
power
cubes,
but
because
the
power
cube
the
engine
gets
hot,
it
would
melt
away
the
rubber
coupler.
A
So
we
stop
using
this
on
as
our
coupler
systems
and
we
went
to
solid
couplers
for
mounting
the
hydraulic
pumps
onto
our
engines,
the
gasoline
engines,
you
can
have
flexible
metal
couplers.
This
kind
of
stuff
is
used
in
3d
printers
for
small.
This
is
flexible.
Those
cuts
in
there
provide
for
flexibility,
and
you
have
four
set
screws.
These
are
at
like
a
45
degree
angle
or
so.
A
That
that
works
for
smaller
applications
like
3d
printers
how
about
rubber
3d
printed
couplers
with
clamps.
So
this
is
like
macgyvering
it.
If
you're
stuck
for
a
coupler
I
need
to
do
something
like
say
you
want
to
mount
something,
that's
pretty
pretty
firm,
but
you
don't
have
any
precision
components.
What
I
would
do
is
I
would
3d
print
out
of
thermoplastic,
urethane
or
other
rubber
print,
a
coupler
that
fits
snugly
on
the
shaft.
But
that's
that
doesn't
have
much
force.
A
But
if
you
now
do
once
again
the
concept
of
metal,
plastic,
composites
or
metal
metal
plastic
composites
with
metal
rubber
composite,
you
do
a
clamp
on
that.
The
clamp
by
itself
would
have
to
be
very
precise,
and
perhaps
you
can
do
a
precise
clamp
like
that,
but
talking
more
like
a
smaller
clamp,
yes,
a
metal
if
you're
using
very
precise,
drawn
over
mandrel
tubing
like
this
kind
of
tubing,
that's
very
precise.
You
can
probably
do
the
clamp
and
make
yourself
a
coupler
if
you
don't
have
access
to
precision,
machining
or
anything
or
even
drilling.
A
So
here
you
got
the
rubber
and
we
clamped
down
on
very
hard
with
metal.
You
can
get
some
decent
of
decent
grab
on
that
something,
and
if
you
don't
have
the
the
plat
plastic,
the
rubber
printing
available,
you
can
use
some
kind
of
a
hose
like
hydraulic,
hose,
that's
metal,
very
heavy
rubber.
We
can
really
clamp
down
hard
on
it
because,
with
the
bolts
for
half
inch
bolt
when
we
looked
at
the
numbers
before
that's
5,000,
pounds
of
clamp
force
per
half
inch,
bolt
four
great
two
bolts
so
that
you
can
get
serious
clamping.
A
The
rubber
will,
like
all
squish
out
as
long
as
it
doesn't
rip
under
the
force.
You'll
be
good.
You
may
not
perhaps
do
like
that
would
be
limits
to
this,
but
for
a
lot
of
applications,
say
a
fast
shaft
coupling
to
something
else,
that's
fast,
which
is
when
it's
fast,
it's
typically
lower
torque.
This
would
probably
work.
So
it's
an
option
to
MacGyver
it
if
you
don't
have
other
options.
A
A
This
is
some
kind
of
a
bearing
in
there.
You
have
PTO
shafts
power.
Take-Off
shafts
are
very
common.
So
a
thing
like
this
that
you
see
in
the
back
of
a
tractor
that
these
things
are
very
dangerous.
That's
the
most
dangerous
part
of
agriculture,
the
PTO
shaft
people
get
wrapped
up
in
this
because
it's
an
exposed
moving
thing.
A
lot
of
farmer
deaths
from
these
things,
but
they
go
on
the
PTO
power
take-off
is
a
six
blind,
six
blind
coupler.
So
splines.
A
Let's
talk
about
spline
couplers
here,
like
we
saw
this
one
PTO
shafts
power,
take-off,
shaft,
there's
motors
that
come
with
this
kind
of
a
six
spline
shaft.
This
is
the
power
take-off
kind
of
a
geometry
for
tractors.
It's
also
good
for
other
transmission
ideas.
So
here
we
use
that,
for
example,
on
the
lathes,
we
mounted
a
hydraulic
motor
using
this
kind
of
a
PTO
coupler.
So
we
had
a
PTO
motor
like
on
on
surplice
Center.
A
You
can
get
PTO
motors
hydraulic
motors
like
this,
that
have
already
this
agricultural
kind
of
spine
shaft,
which
is
a
really
easy
way
to
to
mount
things
onto
a
motor.
They
have
these
locking
power
take-off,
shaft
couplers.
So
basically
that
pin
there
you
put
in
a
pin
you
snap
in
a
pin
and
that
locks
it
around
that
groove
inside
the
shaft.
It's
a
very
easy
and
convenient
way.
So
you
just
basically
snap
it
in
and
out
no
key
ways.
A
A
You
can
have
rigid
clamp,
couplers
like
these,
which
we
actually
we
have
never
used
these
style
ones
like
right
here,
but
they're
they're,
pretty
good,
because
they're
combining
bolting
with
clamping.
So
you
got
these
couplers.
What
you
see
there
is
those
splits
there,
so
it's
both
a
keyway
and
clamping.
So
this
is
as
strong
as
it
gets.
That's
really
good!
That's
kind
of
what
we
were
simulating
with
our
DIY
clamp
coupler
with
keyway.
So
that's
strongest.
You
can
go
so.
There
are
also
tapers
which
are
tricky.
A
I
mentioned
the
one-inch
taper
here
this
one
has
a
one
and
a
quarter,
tapered
shaft,
so
actually
the
the
couplers
are
available
for
that.
So
you
can
mount
wheels
directly
to
that.
But,
as
I
mentioned
in
a
one
inch
shaft,
maybe
you
can
help
us
find
that,
but
we
couldn't
find
a
one-inch
tapered
hub
to
fit
this.
What
we
probably
have
to
do,
that's
the
easier
route.
You
cannot
find
a
hub
like
this,
but
you
can
possibly
find
a
simply
a
tapered
coupler,
and
then
you
weld
the
hub
around
that.
D
D
A
Right
you'd
have
to
start
with,
like
you
cannot
really
attach
anything
straight
to
this,
so
that
would
be
hard.
That's
what
you
have
lathe
chucks
to
clamp
things
on
tightly,
but
yeah.
That's
one
way
like,
for
example,
if
you
have
a
motor
shaft,
that's
too
big
turn
that
motor
on
and
put
a
grinder
to
it
to
get
it
down.
So
it'll,
basically
be
your
Institute
lathe
operation
with
a
grinder
we've
done
that
say
what
people
do
it
and
it
does
workers
you've
got
a
fast,
spinning
shaft.
A
A
A
The
shaft
that
goes
inside
of
this
is
hexagonal,
so
we
use
this
as
a
one
inch
hex
shaft
for
the
shredder
we've
done
that
very
convenient,
because
you
don't
have
to
worry
about
key
ways.
You
can
use
a
set
screw
on
it,
but
if
the
shaft
does
not
move
in
and
out,
you
don't
need
a
set
screw
that
just
stays
in
there
chain
coupler
for
universal
rotor
I
mentioned
one
thing
to
mention,
also
is
Castille
nuts.
So
for
the
tapered
motors,
a
taper
of
the
hubs
on
motors,
like
I,
showed
here.
A
This
tape,
kind
of
a
tapered
motor
you
have
what
it's
known
as
a
Castile
nut
like
a
castle
from
castle,
looks
like
a
castle
Oh.
What
that
does,
when
you
put
a
hub
on
that
it
pushes
the
hub
down
so
that
the
fit
between
the
shaft
and
the
hub
is
really
really
tight,
as
opposed
to
a
straight
coupler,
which
you
can't
make
it
that
tight,
because
it
was
super
tight,
you
wouldn't
be
able
to
push
the
couple
around,
so
you
have
to
leave
a
little
bit
of
space
here
with
the
taper.
A
The
advantage
is
that
when
you
lock
it
in
it
meshes
metal-to-metal
completely.
So
that's
the
Castile
nut
concept,
which
is
important
what
else
shaft
size
adapter.
So
if
you're
coupling
different
sizes
of
shaft
to
one
another,
you
want
to
adapt
it.
So,
for
example,
if
you
have
a
shaft
that
you
don't
have
the
right
coupler
for
it,
you
can
get
an
adapter
so
like,
for
example,
here
you've
got
an
example
where
okay,
this
person
here
there
to
see
the
shaft
is
small,
but
he
put
this
collar.
A
This
ring
around
it,
so
you
see
a
shaft
inside.
That
was
the
size
of
shaft,
but
you
can
buy
these
adapters,
which
are
just
hollow
rings,
with
a
hole
for
the
key
way
that
you
can
then
expand
the
size
of
the
shaft.
So
that's
one
way
to
adapt
things.
The
other
way
to
adapt
things
is
by
using,
for
example,
Lovejoy
couplers.
Like
we
mentioned
before,
Lovejoy
couplers
are
good
at
this.
You
can
have
one
half
that's
one
size
and
the
other
half
could
have
a
different
size
hole.
A
A
So
at
that
point
you
have
a
coupler,
a
sod
coupler,
that's
one
size
and
one
one
half
and
another
on
the
other
side.
So
those
look
like
this,
for
example,
this
is
exactly
what
we
got.
These
go
from:
8
millimeters
to
10
millimeters,
so
one
size
as
you
side,
as
you
see,
is
different
than
the
other.
Then
you've
got
set
screws
to
lock
in
the
shaft.
A
This
could
also
be
done
if
you,
if
you
don't,
have
something,
if
you
don't
have
a
coupler,
that
you'd
be
coupling
two
different
shafts
and
you
can't
find
a
coupler
for
it.
You
can
also
weld
it.
So,
let's
talk
a
little
bit
about
fabrication,
so
I'll
wrap
up
with
the
fabrication
of
that
would
be
you
take
one
coupler
one
size
coupler,
you
cut
it
in
half,
you
take
another
coupler
of
a
different
size.
You
cut
it
in
half
and
you
put
those
two
together.
A
The
way
you
can
get
those
aligned
together
is
you
really
would
need
a
lathe,
because
you
need
to
hold
one
Center
than
the
other
parts
Center,
because
there's
no
way
to
align
them.
If
you're
doing
two
halves
that
have
the
same
shaft
like
say
one
inch
coupler,
you
can
locate
them
radially
by
putting
the
1
inch
shaft
through
it.
For
example,
when
we
we
coupled
a
1
inch
round
shaft
to
a
hex
shaft.
In
that
case
we
can
take
out.
A
A
If
the
two
halves
are
not
the
same,
that
you
cannot
locate
it
with
a
common
shaft,
then
you
need
either
a
different
sized
shaft,
that's
machined
or
put
that
on
a
lathe,
but,
for
example,
with
a
shredder.
When
we
had
a
round
round
shaft
from
the
the
motor
and
shaft
on
the
actual
shredder
was
hex,
we
just
cut
to
one-inch
couplers
one
was
round,
one
was
hex
and
just
welded
them,
together
with
a
1
inch
shaft
to
locate
them,
so
they're
perfectly
aligned
now
here's
what
about?
A
If
you
want
to
make
a
coupler
and
you
you
don't
have
a
coupler.
The
easiest
thing
to
do
is:
take
it
and
say
you
have
a
round
shaft
like
say
and
shaft,
and
you
want
to
make
a
1
inch
coupler
what
you
need
to
do
there
just
take
it
on
a
drill
press
make
a
hole
right
through
it,
with
a
1
inch
down
to
one
inch.
A
How
do
you
do?
How
do
you
then
look?
Do
a
keyway?
If
you
don't
have
any
tooling
easiest
thing
to
do,
is
now
take
up.
Maybe
a
quarter
or
half
inch
bolt
1/2
inch
hole
drill
it
on
the
side
and
weld
a
half
inch
nut
on
the
outside
and
screw
the
the
bolt
in.
So
you
can
do
this
with
with
bolts
with
that's
a
set
screw
example,
so
he
can
do
the
max
torque
applications,
but
you
can
probably
do
take
a
two
inch.
Shaft
put
a
one-inch
hole
through
it.
A
A
So
that's
a
solid
way
to
do
it
because
of
the
force
that
you
have
and
a
half
inch
nut
if
it's
great
you're
talking
about
13,000
pounds
that
you're
clamping
down
so
that
that
could
be
quite
significant,
especially
if
you
maybe
flatten
the
shaft
grind
it
down
a
little
bit
to
have
a
flatter
surface
yeah,
that's
gonna,
be
some
serious
clamp
force.
So
this
is
your
DIY
macgyvered.
A
clamp
coupler
sets
basically
a
clamping
bolt
coupler,
that's
made
just
from
round
shaft,
using
a
drill
press
and
a
welder
which
are
two
common
objects.
B
A
A
What
grinders
we
use
all
the
time
abrasive
cut-off.
You
can
cut
off
things
if
you
don't
have
a
bandsaw,
mig
welders,
the
power,
basically
the
one
into
our
powerhouse
with
that
you
can
build
just
about
anything,
because
if
you
don't
have
grinders
well,
grinders
are
pretty
important,
but
you
can
do
holes
within
assembling
torch.
So
if
you
don't
have
a
drill,
you
can
do
a
rough
hole.
So
basically,
the
entire
tractor
that
you
see
out
there
can
be
fabricated,
pretty
much
with
a
MIG
welder
and
an
acetylene
torch
and
some
hand
tools.
A
But
of
course
it's
gonna.
Take
you
forever.
It's
gonna!
Take
you
quite
a
bit
if
you're
gonna
do
all
of
that.
The
the
difference
between
then
the
basic
workshop
in
a
bit
an
advanced
workshop,
there's
a
few
more
tools
there,
but
CNC
torch
table
being
the
number
one
addition
to
the
basic
advanced
workshop.
You
have
the
120
ton
iron
worker,
the
machine
we
used
in
a
workshop,
which
we
built.
That's
a
hundred
20
tons
of
cutting
force.
So
he
can
just
shear
like
1
by
12
steel
on
it
CNC
mill,
CNC
lathe
yeah.
A
This
would
be
fourteen
thousand
for
this
advanced
workshop
that
a
basic
workshop
it
cost
you
2,000
bucks
about
the
advanced
workshop
is
about
fourteen
thousand,
but
then
again
once
we
have
the
entire
global
village,
Construction
Set
its
self-replicating,
where
you
can
melt,
scrap
steel
to
get
virgin
steel
and
then
machine
it
to
get
precision
parts
and
you
can
build
an
entire
workshop
at
ten
cents
per
pound
for
the
machines.
But
the
rest
of
it
is
a
lot
of
your
labor.
But
if
you
have
a
lot
of
digital
equipment,
that
labor
is
much
reduced.
A
So
at
the
at
the
point
where
we
have
the
full
workshop
built
out,
you
can
self-replicate
it
from
scrap
steel
and
some
other
components
like
scrap
plastic,
that
she
can
make
plastic
parts
or
rubber
parts
like
even
rubber
tires
from
the
waste
stream,
where
you
take
thermoplastic,
urethanes
and
recycled
that
kind
of
plastic.
So
at
the
end
point
you
can
do
a
lot
from
scrap
steel
on
the
wiki
there's
also
a
page
called
Africa
pilot.
A
So
to
get
there
to
what
I
just
described
the
ability
to
go
from
scrap
steel
to
two
machines:
it'll
cost
us
a
plane,
development
time.
It's
about
a
1.6
million
dollars
right
now
you
can
go
through
some
numbers,
but
basically
we
mapped
out
what
it
looks
like
to
have
an
off
off
grid,
open
source
micro
factory
and
what
equipment
do
you
have
in
there
but
to
develop
that
right
now
we
don't
have
that
we
don't
have
a
working
induction,
furnace
or
metal
roller,
not
even
a
working
torch
table
that
that's
robust
for
a
product
release.
A
So
there's
a
lot
of
development
here
once
again:
easily
sortable,
you
swarm
a
thousand
people
on
it
over
a
week
and
you
have
the
entire
thing
built.
But
if
you
attach
some
numbers
say
you
hire
people,
it
would
take
about
1.6
or
so
million
dollars,
and
most
of
that
is
R&D
to
get
this.
These
things
developed.
So
the
bottom
line
is
if
we
can
get
people
around
this
project
and
that's
why
also
I'm
writing
the
book.
This
is
gonna,
be
in
there
explained
in
more
detail
where
we
say:
okay,
people.
Let's
do
this.
A
This
is
extremely
powerful.
We're
leveraging
our
value
millions
of
times
for
what
the
productivity
of
the
open-source
microfactory
can
be.
So
it's
definitely
something
to
consider
to
understand
and
develop,
but
I
think
organizationally
once
again,
the
transition
between
vision
and
execution.
That's
the
main
challenge.
It's
it's!
The
big
lesson
of
management
is
that
there
has
to
be
management
like
we
talked
about
yesterday,
to
to
organizes
as
an
entrepreneurial
effort.
You'd
think
like
ok,
this
is
doable
Wyatt.
There's
nobody
done
it
yeah!
That's
it
that's
a
great
question,
because
it
requires
an
integrated
approach
right
now.
A
Any
single
machine
designer
would
not
be
able
to
design
that,
because
everybody
just
does
one
little
thing
so
here
you
need
the
integration
of
a
lot
of
different
fields
which,
for
which
reason
this
is
a
complicated
project
and
for
which
reason
we
also
encourage
that
people
become
generalists
as
much
as
possible,
because
then
you
can
cross
fertilize
your
knowledge
and
make
the
design
better
and
more
ecological,
so
I
think
I'll.
Leave
at
that.
Maybe
take
some
questions
here
and
we
can
go.
Oh,
the
status
of
us
here
is
oh
yeah.
A
I
want
to
cover
one
more
thing,
though
frames.
So
as
I
said
three
days
ago,
it'll
take
three
days
to
build,
build
a
friend
the
frames,
but
for
a
future,
I
would
suggest
this
there's
a
way
you
can
do
this
without
grinding,
so
we
cut
off
the
pieces
to
a
certain
length
on
the
ironworkers.
So
you
see
those
these
are
some
welded
sides
for
the
heavy-duty
one
one
half
inch
bike
or
inch
frame.
How
do
you
do
it
without
grinding
cuz?
We
spent
a
lot
of
time
grinding
grinding
these
things.
A
E
C
A
So
if
you
would
like
to
do
this
without
doing
any
grinding
and
without
getting
all
these
things
to
the
same
size,
what
you
do
is
you
take
the
longest
piece
and
in
here
whatever
the
so
we
we
build
the
frames
like
this
pattern
here
with
the
four
pieces.
What
you
would
have
to
do
is
take
the
longest
piece
than
account
for
that,
so
you
would
lay
them
out
so
that
the
frame
may
be
a
little
bit
longer
than
the.
What
was
it
three
feet?
This
frame
right
now
is
3
feet.
7.
A
E
A
A
A
Awesome
so
so
yeah
that's
the
way
you
can
do
that,
and
at
that
point
you
have
a
pretty
quick
way
to
do
the
frame
and
you've
got
the
welds.
These
things
are
once
you
work
on
a
corner
of
a
frame
like
here
like
make
believe
the
page
is
a
corner
of
a
table
which
we
did.
We
worked
on
a
corner
of
a
four
by
eight
table.
A
Okay,
it's
not
not
making
an
update,
but
yes,
so
in
the
video
you
just
fill
in
the
weld
there
and
if
there's
a
longer
side,
you
have
to
fill
in
a
little
more
like
if
this
is
a
bigger
gap
at
the
bottom.
You
just
have
to
weld
into
that.
But
that's
it
that's
a
good
way
to
do
it.
So
yeah
we've
got
how
many
other
sides
do.
We
have
right
now
all
got
all
sects,
so
it
looks
like
we're
gonna
build
that
welded
up
today.
C
A
E
D
A
D
D
A
A
Two
inch
shafts
going
here
so
we'll
take
a
picture
when
we're
done
with
this,
but
here
we've
got
like
set
screws
to
actually
clamp
down
on
the
shafts
as
well,
so
I
think
the
clamp
force
of
the
bolts
here
might
be
enough,
but
I'm
observing
more
clamp
screws
on
this
other
side
that
put
set
screws
into
the
actual
shafts.
So
this
is
the
motor
piece
motor
goes
here
belt
here,
and
this
makes
the
big
Universal
axis
a
big
one
with
very
large
shaft.
So
that's
pretty
amazing.
I!
Think
we
should
be
proud
of
this.
A
That's
a
good
and/or,
excellent
prototype
with
3d
printing
mixed
with
metal.
The
metal
plates
are
a
quarter
inch.
I
would
actually
make
them
happen
for
heavier-duty
applications
because
flats
on
metal
they
Bend
pretty
easily,
if
it's
not
an
angle
kind
of
tends
to
bend
but
yeah.
This
is
a
an
amazing
prototype.
We
have
half
inch
bolts
around
the
outside.
We
mentioned
that
the
clamps
strength
of
half
inch
bolts
isn't
huge.
It's
5000
pounds
per
each
of
these
bolts
when
you
screw
down
the
screw
completely
so
yeah
a
plus
to
the
team,
high-five
yeah.
A
So
we'll
continue
on
that
in
the
workshop
and
go
from
there
we're
also
finishing
it
where
we're
getting
all
the
printers
up
and
running
with
that's
the
first
time
we
printed
with
1.2
millimeter
nozzle.
It's
working
well
we're
finding
out
that
the
heated
bad
the
insulated
bed
actually
makes
a
good
difference.
We've
seen
some
uneven
temperatures
on
an
uninsulated
beds,
but
for
large
pieces
like
this,
you
want
everything
to
be
exactly
the
same
temperature.
A
If
you're
printing
small
pieces,
like
maybe
a
lot
of
multiple
small
pieces
on
a
heated
bed,
the
temperature
difference
may
not
make
a
difference
because
it's
about
well
even
the
idea
that
you
have
differential
temperature.
This
has
one
temperature
on
one
side
and
another
on
the
other.
There's
differential
thermal
expansion.
So
that's
gonna
cause
it
to
come
off
the
bed.
If
you
had
one
part
here
and
another
part
here,
small
parts
they're
all
like
at
the
same
temperature,
so
they
would
not
necessarily
peel
off.
A
But
if
you
have
the
larger
piece,
you
have
we're
finding
out
that
it's
super
hard
to
get
them
to
stick
to
a
to
a
non
insulated
better
or
at
least
we
had
much
more
success
with
the
new
insulated
beds,
where
the
temperature
is
much
more
regular
because
there's
insulation.
So
we
had
a
good
time
printing
these,
where,
as
they
were,
coming
off
on
the
older
printers
without
the
insulated
bed,
do
we
print
any
successful
ones
on
the
old
printers?
A
No,
we
did
not,
and
we
suspect
that's
the
difference
so
a
plus
for
the
insulated
bed
on
this
design.
Great.
So
we're
continuing
on
perfecting
the
printers
we're
basically
god.what,
two
or
three
of
the
new
ones
that
are
printing
with
one
millimeter
and
one
point
two
millimeter
and
point
eight
millimeter
nozzles,
so
that
is
good.
We're
really
experiencing
that.
Yes,
the
lines
are
bigger,
like
the
detail
is
not
as
good
but
for
large
parts.
That's
what
you
want!
A
A
A
E
Readout
gap
for
the
x-axis
I
set
up
a
stop
at
the
edge
of
device,
so
I
could
just
take
all
of
these
I
made
eight
of
these
plates
and
they're
all
a
little
bit
different
and
I
could
just
take
each
plate.
I
can
I
could
go
to
this
hole
so
since
I
didn't
have
a
Dro
on
the
x-axis,
I
was
referencing
one
edge
so,
and
that's
actually
good
since
you're
using
a
stop,
you
shouldn't
be
referencing
Center,
especially
since
you're
not
finishing
that
all
the
parts
to
length.
E
If
you
finish
in
the
length
it
doesn't
matter
how
you
put
them
back
in
if
you're,
referencing,
Center
or
whatever,
but
with
the
x-axis
I,
set
my
zero
to
just
about
this
edge
once
again,
no
edge
finder,
just
using
a
standard,
grill
and
I
these.
These
are
three:
it's
off
the
edge
and
they're
half
inch
holes,
and
they
did
that
just
to
conserve
material,
so
there's
only
1/16
of
space,
so
that
got
a
little
hairy
on
some
of
them
where
I've
cut
them
all
of
it.
E
I
didn't
really
have
a
16,
but
other
than
that
I
would
just
find
I
would
get
to
this
hall,
for
example,
standard
drill
it
and
then
swap
out
all
the
plates
and
Center
drill
each
plate
for
this
hole.
Since
these
four
bolt
holes
and
for
most
of
the
parts
of
these
four
bullet
holes
are,
in
the
exact
same
spot
on
each
plate.
Only
the
motor
mount
has
these
three
quarter
inch
holes
in
the
middle
and
while
the
bearing
side
doesn't
have
these
four
five
millimeter
holes,
yeah.
E
So
Center
drill
is
a
small
tube
fluted.
It's
a
drill.
That's
has
enough
stoutness
to
not
walk
when
you
are
marking
a
hole.
So
if
you're,
if
you've
got
your
mill
on
the
exact
point
where
you
want
to
drill
your
hole
and
you
come
in
and
Peck
with
a
center
drill,
tech
like
a
bird
then
that
that
mark
is
gonna,
be
right.
Where
you
want
it
now.
E
I
didn't
have
that
I
had
probably
20
thousands
of
accuracy
there,
because
there's
run
out
on
the
either
the
we
don't
have
a
collet
the
size
of
the
center
drill
that
we
have
so
I
was
using
a
drill,
the
Jacobs
Chuck
and
there's
a
run
out
on
the
Jacobs
Chuck.
So
but
these
are
all
just
irrelevant
details
we'll
take
guys,
but.
E
E
You
can
see
here,
there's
nuts
embedded
in
the
plastic
sheet.
These
I
sized
four
quarter
inch,
so
these
are
seven
sixteenths
hexagonal
holes
which
I
over
sized
by
half
a
millimeter,
but
that
wasn't
enough-
and
these
are
actually
six
millimeter
screws,
so
these
I
mean
it
still
works,
but
instead
of
using
quarter,
20s
I'm
using
six
millimeter
screws
and
then
on
these.
E
E
A
Soli
well,
we
can
just
take
a
heat
gun
to
that
and
just
melts
like
butter,
and
you
can
press
it
right
in.
So
that's
actually
like
when
you're
working
with
plastic,
the
heat
gun
just
softens
it
to
the
point.
You
can
work
it
like
butter.
So
it's
it's
the
same.
That
happens
with
metal
when
you
get
metal
to
very
high
temperature,
but
that,
but
that
is
high
temperature.
So
here
just
a
simple
heat
gun:
does
it
for
working
with
plastic?
A
If
you're
working
with
metal,
that's
induction
furnace
territory
and
and
your
hands,
you
can't
work
that
with
your
hands,
high
heat
environment
and
much
more
dangerous,
but
that's
the
when
you
think
about
metal
rolling.
It's
like
making
a
spaghetti
like
dull
and
spaghetti.
You
know
like
rolling
dough.
It's
literally
like
that
except
you're
at
over
1,000
Celsius,
but
in
terms
of
conceptualizing,
the
feasibility
of
that
you
might
think.
Oh
metal,
it's
like
man,
that's
extremely
hard.
A
Well,
it
behaves
like
like
dull
when
it's
heated
up
quite
a
bit,
so
you
can
conceptualize
that
even
in
a
small
workshop,
if
you
can
get
those
temperatures
like
through
an
induction
furnace,
you
can
make
that
feasible,
very
feasible.
So,
as
time
goes
on,
we've
been
learning
that
all
these
processes
that
happen
in
a
major
industrial
scale
can
be
scaled
down.
Because,
as
I
mentioned
at
one
point
and
as
William
would
like
to
repeat,
we
discovered.
B
A
Oh
yeah,
so
we
discovered
that
industrial
productivity
can
be
achieved
in
a
small
scale
that
part
that
that
statement
is
very
powerful,
because
that
means
you're
bringing
down
the
whole
industrial
system
down
to
the
community
level
for
much
greater
distribution
of
power
and
a
technically
literate
society
of
a
society
that
controls
its
technology
I.
Believe
that's
a
prerequisite
for
a
democratic
society
as
well.
Just
like
we
have
human
rights.
Access
to
technology
is
certainly
a
part
of
a
democratic
society,
and
that's
that's
very
important
to
keep
in
mind
as
we
do
all
this.
A
Yeah,
okay,
so
we're
pretty
good.
We'll
continue
with
this,
so
we're
gonna
be
assembling
the
first
complete
universal
access.
Hopefully,
today
we're
getting
more
printers
printing.
We
just
got
to
get
the
printers,
probably
print
more
parts,
so
we
can
get
experience
with
the
printers
on
the
very
large
nozzles
at
one
point,
two
nozzles,
which
means
you're
printing.
Quite
fast,
we
haven't
even
tried
the
super
volcano
nozzle,
which
is
twice
as
big.
A
We
didn't
even
touch
that,
but
that
gets
us
probably
like
three
times
faster
than
this,
so
if
you're
waiting
for
this
you're
waiting
three
hours
well
at
that
point,
you're
waiting
one
hour
so
from
one
point,
two
millimeter
that
you
could
just
put
double
the
heat
to
that
you
can
probably
print
three
times
as
fast.
That's
how
these
things
work
so
we'll
continue
with
that.
A
That's
gonna
be
later
iterations,
but
for
a
large
printer
like
if
we
make
the
cubic
meter
printer,
you
definitely
want
the
super
volcano
nozzle
and
you
want
it
to
be
open
source
so
that
it's
accessible
for
to
everybody.
According
to
our
mission
of
collaborative
design
for
a
transparent
and
inclusive
economy
of
abundance,
we
got
to
get
those
costs
down.
If
you
want
to
do
like
this
recycling
operations
all
over
the
world,
you
got
to
get
some
of
these
costs
down,
to
make,
make
it
accessible
to
more
people,
so
great
stuff
happening.
