I want you to stay here at the Village long enough to wear out those blades
and all that BIrch is hanging on somebody's wall.
Any help you need is right here.....
Welcome
Hey Tim, pleased you joined the Village.
Everyone steps right up to help when you need it.
Except at the 'Coffee House'... Noone fixes breakfast anymore.
Cut your blanks whatever size,,,, shrinkage and cracking will happen.
Good luck.
IMHO you might get one good one out of 50.
Now, a lot depends on type of wood, patience and atmosphere.
One method you can try is.
Use an IRON ... Iron the wood to remove the warp.
Use a HEAT GUN ... try heating the center of the wood.
Either iron or heatgun will burn the wood....so be careful.

Generally speaking, a warped board will always be a warped board.
You can 'fight' with it all you want, and most of the time it will be a useless endever.
Boards warp due to loss of moisture that is not uniform.
Wood is complicated, depending on how the board was cut and what section of the log the board came from,
determines how the board dries.
You can take a course on the subjest of 'wood drying.'
