I'm a believer in fully excercising bows all through construction, and certainly before they are done. To me, that includes giving a nearly finished bow one, two, or even three overnight braces of at least 8 to 12 hours. SET! STRESS! ANGST! Yeah, yeah, I know, but I look at it this way. Any bow I make will have to endure countless hours at brace while hunting, or even while roving or target shooting. I want the bow to take all the set, weight loss, and tiller changes that it's going to take on the front end, and NOT next week or 6 months later. So, when a bow gets within 2 or 3 inches of full draw, I like to leave them at partial or full brace overnight to allow the limbs to settle in to whatever they're going to do. I prefer to do that more than once on heavier or more highly stressed bows. I EXPECT a bow to take a little more set or drop a pound or two in weight during this period. (I do this in addition to fully excersing the limbs after each step of wood removal and shooting in a bow with 100 or 200 arrows or more, to be sure all is well.) Then once a bow is done, I don't have any worries about it loosing weight, flipping tiller, and all the other nonsense that breaks the hearts of bowmen. I don't want a bow that I have to worry about coddling. When I leave my truck at black-thirty to go hunting, I have no qualms about leaving it strung until I come out a noon or whenever, over and over, all season long. And when the season ends, I know my bow will draw the same weight as opening morning. Perhaps it's not always "needed", but if you've had bad experiences with bows dropping weight or with limbs performing contortions after use, or if you're tired of thoughts like, "Oh dear, it's been an hour, maybe I should unstring this thing," crossing your mind, then maybe you want to try giving your next bow a long overnight brace or three.
Rest assured, a long brace won't kill your bow...at least not if it was designed and tillered properly with dry wood. Again, this is done when nearing final tiller and not during floor- or early-tillering stages, and only when the tiller is looking good. This 67#-er was made with at least two such sessions. This photo was taken right after it was completed. Several hunts and a few thousand arrows later, it still looks the same. Same reflex, same weight, same braced fingerprint.
