Are those simple boxes?

If so, what material, and what size?

Can't be all that hard to get the material and simply cut to size/length.

All you really need is a saw and a drill press.

I did message him, but haven't heard back yet.

The notching/machine doesn't bother me ... was really just wondering the size of the box (3/4, 1 inch, etc) and wall thickness, and the overall total length.

Thanks!

I'm not that bothered by the material itself being "thicker" that what is "commonly available" ...

To me, commonly available = whatever McMaster-Carr stocks ...

(not what's @ home depot or lowes)

There isn't much, period, that McMaster-Carr doesn't carry.

Cool .... that's enough to work with ...

Looks like this is the material ...
