Homebrew PCBs

I LOVE THAT ONE!  It's now my new desktop so I can study it when I want.  :D

Note the centered screws on every axis, that's the best technique in my
opinion.  Even if it is only a drilling station, that cuts down further on
the play.  Those motors look powerful, that machine looks capable of CNC
work.

For the clamps, I was planning on cutting scrap PCB into 2 L-shapes, glueing
2 identical pieces on top of those, but making the top layer protrude about
1/16" into the L opening.  That way the bottom layer is the exact thickness
as a PCB and aligns it on the platform, and the top layer acts as a clamp.
One set will be mounted permanently on the platform as the 'origin' corner,
and the other set will be held down by a butterfly bolt (nut embedded within
the platform surface).

That rubber hose coupling is hilarious. I wouldn't have thought of such a
simple and effective design.
