Here you can see the scribed line that I made from the
last page and I'm using my center finder to line up with it. With my
racks being 3/8" square, I'm going to move over half that distance, or
3/16" and drill some clearance holes for some screws.
|
|
 |
|
Once the clearance holes were drilled, I turned the
angle iron over and countersunk them all for some 8-32 flat head cap
screws. These screws will be used to hold the racks to the angle iron.
|
|
 |
|
If you remember, two of the racks were higher than the others so I had to
make some blocks to make up the difference. Notice the chamfers on the
blocks are larger than normal. This is because the angle iron is thin
and the flat head cap screws are large enough that I needed the chamfer
to extend into the blocks so the screws would tighten down properly.
|
|
 |
I drilled and tapped all the racks with 8-32 threads and bolted
everything together for a test fit. So far things are working like I
wanted.
|
|
 |
Here you can see the flat head screws and what it looks like.

After looking at how things fit so far, I realized that
I'm missing something. The angle iron lock bolt pieces need to be
captured somehow, otherwise they would move when someone tried to pry on
the door. What I mean is, they need a guide system of some kind.
What I came up with is to have a piece at both ends of
the angle iron that was L shaped. But for that to work I needed to notch
all the angle iron pieces at each end (arrow).
|
|
 |
Here is what it looks like with the notch, now I need to make my L
shaped pieces to capture the angle iron.
|
|
 |
I made eight pieces, two for each side and I'll be using some 8-32
screws to hold them down with.
|
|
 |
I figured out the grid pattern and drilled and tapped 16, 8-32 threads
in the sub plate.
|
|
 |
My sub plate is getting lighter but the safe itself is getting heavier
with all the pieces I've been adding. However, this should work pretty
good.
