It took a small amount of set early on in the process but has not taken on any additional set recently. even after getting past brace. Here's the really wierd thing, I could just squeeze my middle finger through the gap between the centre and the bench, but they both rubbed the skin, then I tempered the bow - only a light tempering, and the bow was not strapped down - and then re-measured the set and it has almost all disapeared. Long and short, one limb has no set, the other has a natural deflax-reflex curve which has taken on about 1/4" of additional set
