Okay,
we're
here
with
brianna
she's
working
on
the
ironworker
machine.
Yes,
give
us
a
little
tour
all
right,
so
this
is
the
table
where
I've
put
stuff.
That's
mostly
finished.
These
here
are
the
vertical
linkages.
They
basically
attach
the
linkage
to
the
top
arm
and
you
can
see
I
press
fit
these
butchings
here
or
freeze
fit
and
here
and
here
and
then
this
one
I
accidentally
machined
it
too
big.
So
I
have
to
put
shims
in
there
to
fit
the
bushing
in
okay.
How
do
you
press
fit
it
with
one
machine?
A
A
It
was
supposed
to
be
3.003,
which
is
why
the
bushing
won't
fit,
and
so,
but
I'm
gonna
have
to
put
shims
around
it.
But
basically,
you
heat
up
the
area
that
expands
this
hole
makes
the
metal
hot
and
big,
and
you
freeze
the
bushing
with
dry
eyes,
or
you
can
do
regular
eyes.
It
depends
on
how
much
you
machine
it
under.
So
I'm
machining,
three
thousands
under
it's
one
thousand
per
inch
and
that
ensures
that
when
the
bushing
goes
in
there,
it
ain't
coming
out.
A
If
you
machine
it
closer
like
some
of
these
bushings,
I
accidentally
did
it
like
three
point:
zero,
zero,
five.
Instead,
so
it's
two
thousands
bigger
and
I
didn't
need
to
heat
it
up
with
the
torch
but
they're
going
to
come
out
easier,
which
there's
no
forces
pushing
them
out.
So
it
doesn't
really
matter,
but
ideally
you
want
them
in
their
solids.
So
there's
no
reason
they'd
be.
You
know,
spinning
around.
A
Yeah
so
freeze
fit
you
freeze
it,
you
stick
it
in
the
hole
you
might
need
to
hammer
it
down.
So
what
I
did
is
I
took
a
big
plate,
put
it
on
top
and
hammered
the
plate
so
as
not
to
damage
the
bushing
and
the
bushings
are
simply
made
from
a
three
inch
outer
diameter
two
and
a
half
inch
inner
diameter
tubing
and
machine
them.
So
this
surface
is
perfectly
flat
and
same
thing
with
the
other
side
and
they're
also
chamfered
a
bit
on
the
outside
in
here.
A
Just
so
they'd
go
in
easier
and
how'd.
You
do
the
hole.
So
what's
we'll
have
to
go
to
the
back?
For
that
use
a
boring
tool,
you
can
buy
one
for
the
mill.
We
have
a
boring
machine
which
is
actually
like
much
higher
quality
than
a
mill.
So
I'm
using
that
because
it's
a
lot
bigger
a
lot
easier
to
work
with,
because
our
mill
is
just
in
horrible
shape.
So
I'm
using
that
to
do
it,
but
if
you
want,
I
can
show
you
guys
I'll
show
you
these
pins
too.
A
These
chips
pens,
I
have
the
rest
of
them
back
there.
Pins
were
definitely
more
challenging
than
I
thought,
because
the
pins
not
only
do
they
need
to
kind
of
go
through
here
and
provide
lubrication
to
the
bushings,
but
they
also
need
to
clamp
this
together,
because
when
you
have
the
final
machine,
these
two
pieces
are
basically
going
to
be
like
this
and
there's
going
to
be
a
piece
between
them.
So
you
need
to
hold
it
together
so
that
the
top
piece
can't
flex
in
any
direction
whatsoever.
A
So
to
do
that,
I
got
really
big
threaded
rod
and
I
made
it
fine
threaded
rod
and
said,
of
course,
so
that
way,
it's
far
less
likely
to
slip,
probably
use
some
lopsided
on
there
or
something
to
make
sure
it
goes
on
tight.
But
you
see
these
markings
around
the
side.
There
are
grease
channels,
and
right
here
is
where
the
grease
fitting
screw
is
in.
You
can
see
it's
threaded
in
there
just
drilled
all
the
way
through,
not
all
the
way
through,
because
the
drill
bit
is
impossible.
A
I
mean
I
could
probably
buy
one
that's
longer,
but
the
one
I
we
have
was
only
like
four
inches
long,
so
it
goes
to
about
here.
So
you
just
drill
the
holes
center
hole
through
here
and
then
holes
for
the
grease
to
come
out
through
there,
and
then
you
need
channels.
The
grease
can
typically
spread
like
half
inch
to
an
inch
away
from
the
channel
depending
on
the
clearances.
A
I
should
have
maybe
drawn
them
out
that
it'll
work,
so
that's
that
and
the
grease
can
go
through
here
and
go
all
around
and
then
when
it's
in
here
it'll
make
it.
So
these
don't
stick
together.
It's
gonna
be
a
firm
fit
a
little
bit
of
play
a
little
bit
of
play,
but
you
need
that
considering,
there's
gonna
be
three
pieces
and
one
of
these
bushings
might
be
torque
somehow
or
something,
and
this
is
holding
it
all
together.
Anyways
there's
I
mean.
A
Maybe
it's
like
a
thousandth
play,
but
that's
it
so
there's
that
so
two
pens.
So
this.
How
deep
is
that
in
like
like
an
inch
or
two
yeah?
It's
maybe
three
quarters
of
an
inch
in
a
machine
shoot.
I
don't
have
anything
with
me.
Basically,
I
machined
a
hole
for
this
and
then
chamfered
the
top.
So
that's
where
the
weld
went
was
in
the
chamfer.
The
tamper
was
out
to
like
here,
so
you
can
kind
of
see
it
how'd.
A
A
Why
was
the
hole
so
shallow,
because
I
mean
it
just
needs
to
be
deep
enough.
Where
you
can
you
get
it
in
there
and
it's
square
and
you
can
weld
it
because
it's
just
another
small,
I
figured
it
needed
to
be.
How
deep
was
that
it
was
pretty
much
the
same,
but
you
said
it:
it
tilted
a
little
bit.
That's
because
it
wasn't
deep
enough
yeah
it's
because
the
the
rod
was
actually
smaller
than
we
thought
it
was.
A
It
was
smaller
than
the
the
havoc
diameter
or
I
think
it
was
like
supposed
to
be
one
inch.
So
it's
smaller.
So
there
was
some
play
and
I
used
some
shims
in
there,
but
it
didn't
end
up
being
perfectly
straight
either
way,
plus
it
can
kind
of
warp
unless
it's
a
tight
fit.
These
were
all
pretty
tight
fit,
but
this
can
warp
like
when
you're
welding
it
unless
it's
a
tight
fit.
So
we've
got
the
linkage
arms
yeah
design.
This
is
pretty
much
a
technical
description
here,
but
yeah
yeah.
A
These
linkage
arms
are
also
you
see.
These
holes
are
threaded,
there's
gonna
be
grease
joints
in
there
too
or
grease
fittings,
and
that's
because
these
are
going
to
be
rubbing
up
on
stuff
on
the
back
side.
So
we
want
to
make
sure
that's
nice
and
lubricated,
so
it
doesn't
bind
up
if
you
leave
the
machine
sitting
for
a
while.
A
So
that's
what
those
are,
and
then
this
is
just
one
more
thing
to
keep
it
pulled
together.
This
is
going
to
be
for
a
three-quarter
inch
bolt
here,
just
mag
drilled,
it
out
and
another
bolt's
just
going
to
be
holding
everything
together,
because
that
piece
is
under
a
lot
of
stress
when
you
shear.
These
are
what
pulls
this
shear
down
to
shear.
So
you're
shearing
like
this
and
you
know,
you've,
got
your
metal
here.
There's
a
ton
of
force,
probably
more
than
a
ton
of
force,
literally
pushing
it
out
this
way.
A
A
Let's
see
so
these
are
what's
going
to
be
the
washers.
I
did
some
square
in
some
realm.
My
grandpa
teased
me
about
them
being
square
said
it
looked
like
like
crap,
so
I
did
some
round
ones
just
to
please
him
and
these
I'm
gonna
weld
on
it.
I
waited
until
this
was
all
done
to
weld
it,
because
I
wanted
to
make
sure
this
didn't
need
to
be
machined,
which
it
did
because
this
was
two
and
a
half
diameter.
A
This
is
two
and
a
half
diameter,
so
pretty
much
exact
fit.
So
I
had
to
machine
it
down
a
bit
to
make
it
work.
I
think
in
the
future
I'll
get
thinner
wall
bushings,
I
don't
know
if
they
make
them.
That
would
be
just
like
a
few
thousands
larger
than
this.
I'm
not
sure
I
got
to
research
it,
but
so
this
is
basically
going
to
be
welded
here,
along
with
a
nut,
and
then
that's
going
to
be
so
that
you
can
tighten
it
when
you
get
it
all
together.
A
A
Okay,
you
can
see
these
are
counter-bored,
that's
so
that
I'm
going
to
put
some
socket
head
screws
in
there.
So
that
way
it
it'll
tighten
down
the
piece
below
which
is
actually
that
piece
over
there.
Okay,
those
two
pieces,
and
that
way
it's
perfectly
flush
on
the
top,
and
I
did
this
using
a
mag
drill.
So
you
take
the
mag
drill.
You
first,
you
punch
a
hole
drill
it
all
the
way
through.
So
it's
like
an
eighth
inch
diameter
hole
and
you
use
that
hole
to
center
your
mag
drill.
A
So
first
you
drill
the
big
hole
go
in.
However
deep
you
want
the
big
hole
to
be
and
then
flip
it
over
and
go
through
the
center
on
the
other
side,
because
the
slug's
still
in
there
and
you
drill
all
the
way
through
and
that'll,
knock
out
the
other
slug
as
well.
So
then,
you
end
up
with
this
nice
counter
bore,
but
then
this
hole
right
here
I
messed
up
on
you-
can
see
that
it
was
the
magpul
wasn't
starting
right.
