Homebrew PCBs

Hi Chris, Volkan, Herbert, all,

I'm in the process of designing and building a small PCB router.  I'm 
using parts from two linear ways I collected a few years ago, and 
stepper motors I had on hand.  I'll probably time-share one of the 
controllers I built for my Sherline CNC lathe and mill.

I'm using the linear ball screw sleeves and ACME threaded nuts from two 
ways, and a similar but slightly smaller unit for the Z.  I'll need to 
make up translation blocks" (drilled for the bushings and ACME nuts) for 
the Y and Z axis of my gantry style mill.  Simple rectangular aluminum 
stock makes up the frame and the two uprights.

If anyone is interested, I can post pix of some of the stages of 
construction.  I might be posting it on The SherlineCNC list as well.
