I can make the frames for 2 Curlews out of one 5x5 sheet. I laminate my combings. With a little care laying out and putting frames inside the rings you might get it all out of 1 sheet.

One sheet will do. You will just have to cut out and arrange all the peices to keep the waste down, but there is no reason not to get it all on one sheet.

Great, thanks for the quick response. I'll start with one sheet and see how I do, but I'm known for making mistakes...I mean learning opportunities.

I alway buy at least an extra sheet. I make mistakes and hate running for more. Besides I always have a use for any extra.

That next boat thing can be a problem sometimes. Once in a while the "entire" household doesn't understand.

I have used some stuff for a variety of projects called "Integra-Ply" which is underlayment for tile floors. I think it is similar to baltic birch. There are no voids and it uses exterior glue. 1/4" is 5ply and 1/2" is 7 ply. In my opinion it is a quality product, but I wish I knew more about its resistance to decay or breakdown. It seems to me that it is a cost effective solution for boats that do not remain in the water.

No matter how much I search I can not find any good specs on the material. The fact that is is made as underlayment scares me a little. The characteristics of a good underlayment are smoothness and puncture resistance. This means it may very well have been designed such that the resistance to a frame made of it breaking may be terrible. I would want to find more about it, or at least do a test comparing frames made of a known plywood to it first. Might be great, but I am skeptical till I know more.
