Thanks everyone.

I ended up spraying some adhesive to the ply, putting the pattern down and cutting it out. Then traced around it with a fine pencil, pulled the paper off and cut it out.

Worked pretty well, but time consuming.

I have most of the lite ply parts in cadd now for laser cutting, but wanted to make a test run before spending the money on laser cutting.

I have a few spots to touch up to make sure it all goes together.

Next is laying out all the balsa parts and doing it all again.
