Razor and all,
Could you take the temperature of your hot box as you used it to cure that bow, and then either fit another light bulb or use a heat gun to up that temperature by 15-20 degrees, and try to reset that limb?
Those with more experience may know if this may work, or is just a waste of time. My thinking is, that by raising the temp of the epoxy above its original cure temp, it may soften, and allow the lams to shift enough to "reset" the offending limb.
What say, bowyers?
