I failed with my first attempt at a recurve bend. http://lumberjocks.com/Loren/blog/38142
I was prepared for that failure since I used a strap on only
one side. This time I’ve added another backing strap and
a fixture to make the transition.
While the backing strap wasn’t directly “backing-up” the
wood (which helps with grain blowout) nearest the
transition, the part came out cleanly bent with neither
expansion failure nor compression crumpling.
