Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

Well I upgraded from the model 395 Dremel (5K RPM max) to a 20K RPM
adjustable Proxxon drill and it has no run out of significance. I can
do 60+ gauge holes for vias w/o breaking carbide bits.
Also I have a super bright LED placed underneath the press, as I had
with the Dremel press for back lighting the PCB when drilling, it works
very well.
For straight cuts I upgraded from a carbide scribe and snapping to a 4"
mini table saw /diamond blade, and added a small vacuum for dust suction.

No longer have any of the alignment issues etc.
The Dremel is used for grinding and metal cutting and polishing now. I
place no lateral stress on the Proxxon bearings to keep the run out away.
