Well I cut it to 43", so I can easily get 2 longer blanks from it by flipping the pattern.
As I resawed it, first I did a test of cutting 1" off the end to rip it in half and see if case hardening had caused any issues, as I do not know if it was kiln dried or not, suspect it was. It looks like it was milled a long time ago. It was a stash board in someones collection, I believe he was a boat builder. It did not cup when ripped, well very barely, about 1mm in 14". Thinking about it though, I am putting a top on it, and, from an engineering standpoint, it should have a back, to balance the laminate.
Any thoughts on this?
The board is very fully cured, and very dimensionally stable. However, putting a veneer on one side will unbalance it. Is an epoxy fill, not way too thick nitro finish enough to hope that this will not warp in time? Should I pay attention to which side is up and design it so the (theoretical) convex side is up? Should I put a back on it too?
