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

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.

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!

... all the stuff availabe in US makes people feel like emigrate there :D

 

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

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

dense 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!

Big improvement.

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