Bending wood with ammonia is not really DIY, but I show the process, which is extremely effective. There is also a commercial product that is pre-treated flexible wood, which hardens after being clamped in the desired shape.

Hmm, it seems the product may no longer be available -- I can't find it at Inventables.
