Where I used to work the have a big oven that they use to make gaskets, they have been laying off people recently, the only have engineers working on designs but not manufacturing so I will talk to my cousin husband who was my boss to see if they are going to sell that oven, it's old but it works, and I can do some custom gasket with it too.

Oh yeah gonna bring sliced ham and bread.
A jig in a steam box, maybe even a oven to dry out the ply also. That is a good idea and would give true fits every time. Then all you may need to do is fine tune the frame to the bottom.
And all joking aside, you are doing good work.
