: What is the bend radius of the various 1/4 and 3/8 plywoods? I am looking for
: something that will bend to a 1 ft radius and want to be able to build an
: eventual thickness of 1/2 in.

I can't answer that question directly, but I made a form and clamped 5 layers of 4mm okoume ply to make 16" radius deckbeams for a S&G yak. If you want 12" for the final radius, make the form smaller, say 10.5 to 11" in radius to allow for springback. Lee Valley/Veritas website has a wonderful discussion on steam bending woods ... radii of 4" are apparently possible with woods like ash..maybe plywood isn't the best choice for tight radii (radiuses(?)).
