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.

Thanks. That is my goal.

What is the life expectancy on this monstrous thing? I'm just waiting for you to post a picture of it in pieces lol. And man that handle is ugly

Here it is drying its sinew taking on its new shape.

reminds me a bit of this 200+fps at 10gpp glass bow's shape

Seeing your force draw curve on an actual graph changes the perspective a bit.  What I thought was stack is clearly just a slight flaw in your precision measuring system. ;)   That's good.  I'm wondering how the latest adjustment is going to affect the performance.  I wouldn't think you will gain much in string tension, but I could be wrong.  Josh

Loon, I certainly see a resemblance. I need to get mine reflexing earlier for that shape though, and I am still going through stages if experimentation before I reach althat and understand why what shapes work and dont.

In this new profile, I am going for 2 inches of retained reflex. In the above pic it has 2 3/4" reflex. Sinew is still curing and shrinking, we will see what that does for me.

With the induced reflex, and I am going to tiller it down to 65@28 rather than 75@28, the belly should have fresh new wood for compreasion. We will see how it works out. I really am hoping for better early draw weight.

I think, when I start tillering this back, I am going to get the tips to start bending first, then try anf move the tiller to the inner limbs. That way the inner limbs release their energy first, and the tips act like the flick of the wrist as a ball is pitched.

  This seems like a tricky proposition. Which part will bend in order to achieve brace?

  I am convinced this is the optimum design, maybe 30% less bending limb.

  Pretty much but you can't do it with wood.
