Homebrew PCBs

Here are a couple refinements to the kindergarten sketch-

Press-

That candystriped support at the back could be a fat dowel or 
whatever, attached to the base to stiffen up the guide bars.

Holders-

It could maybe be less complicated than that and still work (paper 
theory again). The front, drill holding part of the standoffs could 
just be pipe clamps or a metal strap. The holders could also maybe be 
cut out of a single triangular piece with the drill mount hole already 
in it, then you could just saw the front off to get the two pieces. 
Also, all the pulley crap could just be large screw eyes.

PS- I've probably spent more time typing and sketching than it might 
have taken to make the damn thing. ;)
