Re: [CAD_CAM_EDM_DRO] Router - Cutting Thin Sheet Clamping??

Ok, i will tell you how to do it, but don't tell anyone my secert! You will need some double side tape (like carpet tape), try to find the paper kind, just easier to work with, and a roll of "transfer tape", you can find this at your local sign supplies, or ebay.

Now apply the transfer tape to the bottom side of you wood, you may want to clean the wood first, so it will stick better. Then use small pieces of double sided tape on the transfer paper in different places (like the corners, middle, just ramdom places) . This will hold down you wood to your router table.

Here is the tricky part.... measure the wood, so you will know the thickness ( in thousand of an inch). You have to know how to calibrate you cnc router to the top of the material, so you can set you "Z" depth to the thickness of the wood your going to cut. If you done it right, the router bit will just kiss the transfer paper (transfer paper is about .005 of an inch thick), and you will have some very nice parts (without flying out the table or getting damaged by the router bit!)

I do it all the time,

I am building my first CNC wood router mainly for cutting model
aircraft parts out of 4mm coroplast and thin Balsa Wood (1/16 to
1/8" Thk) and maybe upto 1/4" Ply.

I plan on a vacuum hold down system.

My question is how can I fixture this material so that I can cut
through the entire thickness without destroying my table? I am sure
there are lots of people doing this.

Thanks for any suggestions.
