Sometimes you have to be creative to fix a problem;
I grabbed two of what I thought were matched osage billets to make my latest bow, the rings were the same and 10 years of shop sitting had turned them into exactly the same dark color. As I cut the splices I realized the billets weren't even close to matched, one was yellow osage and one was dark red osage, I thought it wouldn't matter and proceeded. Turned out the limbs had a different recovery rate, one was snappy and one was mushy. The red limb would relax after 5 or 6 shots and throw the tiller way off.
I heat treated the limbs, which almost evened them out, then heat treated the red limb a second time, that did the trick and made the bow hold tiller, it became a good performer and very stable shot to shot.
Another thing; why does he splice go up above the arrow rest and handle? Some old man thought he had measured the limbs correctly to have the top limb an inch longer than the bottom so the snappier limb would be on the bottom. Turns out he had them reversed so he moved the handle down to get things back the way they were intended.
