No Eddie, you see it right. The trick is on these bows, is to deflex the fades so to stress the limbs less.

Looking at your force draw curve, I can see exactly where your recurves are doing there thing.  That last entry tells an ugly story however.  At 27" stack is showing by jumping 9 lbs.  Your entry at 28" would suggest that the belly is now thoroughly crushed.  It should have been an even more drastic jump in weight.  I'd almost be willing to bet that you're readings throughout the force draw curve will be significantly less than the first time you charted it.  The last inch must of been a smidge too much.   Josh

I just ran through the draw with a scale again. Nothing has changed. I dont think the wood has broken down yet.

Im sorry, but I dont think I can do that.

There is another box inside with towels wrapped loosely around a pillow. It stops the arrows well and they never penetrate the soft arrow stop, and pull out with little force.

I have an inability to leave well enough alone. I am soaking this bow in the bath for a day, then pulling off all the sinew, hopefully in a solid sheet. Then, taking the bow, clamping it down into a reflexed midlimb to outer tips, letting the bow dry, then gluing on the sinew as a single sheet, to dry into more reflex, hoping for 2 to 3 inches, measured from the back of handle to the nocks.

Just got the sinew off. I was able to fillet it off like fish skin only harder.

I've attached a graph of the force draw curve based on the data Sleek provided on the previous page, in case anyone wants to see it.

Eric, I appreciate  that.  That bow had zero initial draw weight. Hoping to fix that.

Lol, knew you couldn't stop, you're an edge pusher for sure. Luckily you seem to be pretty damn good at it as evidenced by these self bows that are damn near horn bow specs, lol.

I cant quite recal but 7 inches is a ballpark figure. Thats my usual.
