It compleatly depends on what kind of wood, and its thickness, the thicker the wood the harder to bend (duh). but if you have paper thin Walnut for example you can almost fold it when it is wet/steemed (steeming works better in my opinion but that might just be me) yet 1 inch walnut can barely bend 90° so it all depends... if you steem it it drys quickly, but if you get it wet it is slower and can come out of shape less obviously until it is too late.
