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. http://boingboing.net/2011/05/06/inventables.html Hmm, it seems the product may no longer be available -- I can't find it at Inventables. https://www.inventables.com Pre-treated flexible wood product patent: https://www.google.com/patents/US5360631
