Making my own foamboard

Hi could you tell what kind of paper are you using since I used paper similar to thickness of paper in art files..
It is currently drying

Well it is almost dry and paper has started peeling a bit from edges

yes, that happends. what i actually do is to cut at least 1/2 inces from the edges.

Ohh is there any fix for now that I have pasted it as is since it is a pretty large piece I don't want to throw it away

Add an extra bit of glue under the edges it's lifted, or better yet rub glue over the paper

I added a bunch of glue under the paper with slome mist and left it in a room(without fan) standing so both sides get dry same..
When I checked just now it was warping all over so I put it under a bunch of books...

Yea I've never gotten a truly flat sheet, I've had them almost flat, and some really warped. Doesn't make much difference when you build the plane.it pulls everything straight.

The sheets weren't sticking good so I have just peeled them and they came off without any issue..
Will try thinner paper with wheatpaste

I dont know why my wheatpaste is not sticking paper to the depron but is very good adhesive when sticking paper on paper

Proper cooked wheatpaste with the correct amount of water? Should be like tomato soup on your plate thick.

It was like that but wasn't sticking
anyway 50%PVA glue with paper as thick as printing paper worked great...
It had the adhesion about the same to premade foamboard though I had to put weights on the board to keep it from warping

I am interested in learning more about your hot wire cutter setup. Did you build your hotwire cutter? If so, can you share photos and materials that you used?
