Crazy glue would stick alright but you'd never get it back off. It's thin enough to soak into the plastic. I'll pick up some carpet tape tomorrow and give that a try. If I can't find that I'll go for some other double sided tape. I need to go to TSC tomorrow so we'll see what they have, if not then Meijer is right across the street.

In a previous life the machinists would use carpet tape to hold down aluminium strip that was being milled into tapered shims using a facemill, so should work fine for your job.

And naphtha works pretty well as a release agent. We used it a lot at the guitar-building school, to release plexiglass templates from the workpieces.
And the kids still managed to break them...

Well I'm happy to report that tape worked. TSC didn't have carpet tape so I used Gorilla mounting tape. It's some double sided rubbery stuff. I was even able to use the same pieces to do the back side of the same piece, then two new strips for the next one. Still have one more to go, the 8x10. I'm sticking them to a piece of corian, a sink cutout.
The problem with the mounting tape is that it's expensive. It's about $10 for 60". Depending on tonite/tomorrow's snow I'll be stopping at home depot for some carpet tape. More bang for the buck. Thanks everyone!!! I'll post pics of the setup when I do the big one.

I've used this stuff on aluminum plate before and it held fine. With all the area on a sheet like you are working with, the tape doesn't need a lot of stick. It's also a lot easier to get off than the high tack stuff. Tom

Forgot to hit home depot, went to Meijer earlier, wish I saw this earlier Tom. Looks like a trip back to Meijer tomorrow - think I have some Rx to pick up tomorrow anyway. Website says they have it on the shelf.

There are also several low temp paraffin's available through various industrial suppliers such as McMaster Carr. These are a very hard paraffin designed specifically for the purpose of holding difficult to hold parts for machining. They work exceptionally well for parts where shape and size will not allow conventional clamping.
