A
With
the
sides
assembled
basically
so
far,
the
assembly
process
has
been
loosely
assembled,
the
two
and
these
two
sides,
and
then
you
mount
the
steppers.
Then
you
put
these
shafts
mount
it
on
with
the
sleeve
bearings
of
the
support
supporting
angles
here,
and
then
you
try
to
align
it
right
so
that
it's
perfectly
perpendicular
to
the
axis.
Well,
as
so
as
far
as
so
far
as
you
can
tell
right,
and
then
you
hand
tighten
these
screws
and
that's
what
I'm
doing
right
now,
uh-huh.
B
A
A
Okay,
it
ensures
perpendicular
line,
and
then
this
is
the
parallel
alignment
template
which
ensures
that
the
along
the
parallel
to
the
bar,
you
have
the
correct
lengths
for
each
of
these
pieces
and
then,
finally,
what
I
needed
to
do
was
make,
as
you
can
see
there.
Are
these
angle
holes
right.
So
you
want
an
angle
alignment
template
and
you
actually
want
it
so
that
I
did
the
math
on
this.
If
you
want
a
proper
triangle
corner
like
this,
you
need
the.
A
If
you
go
here,
you
need
the
distance
between
that,
like
that
hole
and
this
whole
along,
like
parallel
to
the
bar,
which
is
right
now
40
millimeters,
to
be
double
the
distance
between
this
hole
and
the
inner
edge
of
this
angle.
So
here
about
parallel
along
the
angle,
is
40
millimeters
and
here
is
20.
Millimeters
such
as
this
is
also
20
millimeters.
So.
A
One
so
the
angle
one
was
more
difficult
to
make,
because
I
had
to
first
drill
a
hole
that
would
become
the
reference
when
I
was
a
drilling,
so
hence
this
whole.
Actually,
I
would
put
em
2.5
screw
into
here
and
then
I
would
kind
of
like
do
that,
so
the
so
that
the
whole
would
refer
to
angle
here
then
somehow
I
had
to
move
40
millimeters
market
here
and
then
transfer
that
mark
on
to
the
other
side.
A
Here
and
now
after
I
put
the
hole
through
here,
you
have
to
transfer
this
mind
here,
but
I
found
that
if
you
just
use
it
combination
square,
it's
not
like
it
takes
too
much
time
and
it's
you
have
to
fiddle
Valentin
so
too
much
so
I
decided.
Why
not
just
place
a
bar
like
this,
and
you
could
just
forget
about
the
combination
square.
This
is
your
combination,
square,
a
new
market
and
it's
much
faster.
A
But
after
doing
this,
I
discovered
a
better
way
to
ensure
more
accuracy,
because
I
found
the
like
by
using
this
angle,
template
I
had
as
opposed
to
these
templates,
which
I
just
drilled
through
the
holes.
I
had
to
actually
remark
these
angle
holes
and
then
position
it
right
while
I
was
grilling,
so
remove
this
angle,
template
and
instead
of
referring
from
holes,
I
was
I'm
now
going
to
just
go
for
referring
from
data
edges.
A
That
is
what
I
was
doing,
is
have
a
reference
hole
here,
and
each
other
hole
is
a
particular
length
away
from
that.
So,
for
instance,
this
is
eight
millimeters
away
from
this
reference.
Oh,
that
is
a
16
16
millimeters
away
from
this
reference.
Oh,
that
is
70.
That
is
170,
so
it
was
all
from
this
reference
ho.
But
now,
if
you
do
it
from
the
edge,
what
I
can
do
is
say
have
a
particular
angle:
I
just
align
the
data
match
to
the
workpiece
edge
and
then.
B
B
B
A
B
A
B
Document
that
elsewhere
and
for
now,
so
how
long
did
it
take
you
to
build
this
frame
so
far
I
mean
say
you
had
the
technique
worked
out.
How
long
did
it
take
you
to
work
out
the
technique
so
far,
I
mean
you
spend
a
few
days
on
that
right,
yeah,
uh-huh
and
then
once
you
have
it,
how
long
does
it
take
you
to
actually
build
this
structure
here.
