Really
I have see them set forward then reflexed with good heat and seen no ill effects to "working limb " what so ever. In fact we just did one like this. Real dense orange, hard, close ring piece and it held every single bit we put to it. Its a killah Bart says. One the finest we've made in some time. Hard to remember I make a chit ton of bows and forget most of em. I do remember Gary Davis telling me "he liked billet bows" and that was one reason why. The other is rather obvious.
Get up with the Recurve shoot out. Ante be getting on the hard reflex caul soon. Not going to burn the bejesus out of it like i seen guys do though.
