PCB CNC Mill: Clamping makes a difference
This might be useful to anyone else here with a DIY CNC who does PCB milling: http://blog.holyscraphotsprings.com/2011/05/good-circuit-boards-require-good.html
I've had a really tough time figuring out how to clamp my PCBs: my boards often look like the "bad PCB" here: http://www.flickr.com/photos/11461247@N02/5697373918/
I'm looking forward to testing out better clamping so my boards don't slide or vibrate so much: http://blog.holyscraphotsprings.com/2011/05/good-circuit-boards-require-good.html

Speaking of clamps
Rockler Woodworking has a bunch of T-Track stuff, toggles and the like. All great stuff and well-made and probably much cheaper than a supply house for mills etc.
There was another place, Little Machine shop --they sell parts for all the cheapie mills and lathes. Harbor frieght, Grizzly and Central Mechanic. Might be some stuff there to help you as well.

Clamps and T-Tracks
Wow! I like the T-slot cutter -- it looks like I could use my router to cut slots in the table and then clamp stuff to it.
Great links, thanks!

Following some links,
starting at hackaday.com, I found millpcbs.com. On that site, superglue on a metal plate to hold the pcbs in place is mentioned.

clamping ...
Adding +1 to birdmun's question? Double sided tape no worky?

Have you tried
dense double sided tape?

Re: Double-Sided Tape
I have not! I kludged some clamps using wood scraps, PCB scraps and masking tape, and haven't upgraded. I've added dense double-sided tape to my shopping list. Thanks!

Mixing Fender washers sizes make for good heat sinks too ...
Make good guitars?
