Homebrew PCBs

Hi Zoran,

OK, different animals!  Thanks for alerting me, I might have gone on and
tried to use my lamps for photo resist, and not have realized why they
didn't work.

Right now, I'm concentrating on the mechanical method of milling isolation
traces on PCBs.  It "fits in" with my CNC work.  I'm currently working on
making parts for a 12" x 12" PCB router of my own design.  I'm trying to use
"on hand" linear motion components, although I did buy some linear round
rods and linear bushings on E-bay.  I'm still looking for flanged ACME
bronze nuts and ACME threaded rods (to match some I have).  

Best regards,

Alan  KM6VV
