Well I think it will end up a 1-5/8 or there abouts.67ntn 9 inch handle. Pretty much same bow just another inch of reflex if I can manage to hold it thru tiller. Arvin

Wish I could load video. I’d show the back of the selfbow. Oh there I go again with bad grammar.  Arvin

Surfaces ready to glue up. A quick dry check. Good but not perfect.

Question? What glue would y’all recommend for boo to Osage? Unibond 800, smoothon, or hide glue are your choices.  Arvin

I always used URAC and think unibond is about the same, but everyone seems to be using smooth-on now.  Both will work.
Seems like common sense isn't very common any more...

the epoxy might be better if you are concerned about gaps

Why do you have the bamboo so thick? Thin boo glues up way nicer, it conforms to the waves.

What DC said...that stave with bamboo that thick and you will have a war-bow weight when it dries... are you adding a power lam?

No power lam. Simple composite. What’s more heavy bamboo or Osage for a backing? Might want to trap. If I end up with less Osage it might cut down the mass weight and still have a great backing. Just trying stuff. Arvin

I don't think that adding the 16-18" power lam would make it a complex composite...it's just a small piece to stiffen the riser/grip area... If you glue what you have it might not bend after drying.  LOL

 Bob that’s going to happen in the tiller if I do my job right. Painters tape keeps all that glue I will have smeared everywhere off the back. I hate glue and paint. Avin

We had a bit of a discussion about how long a power lam had to be to bump you up a class. I don't think we ever got to an definitive answer but it was something like, if the "reinforcement" goes past the fades you go up to complex. At least that's what I got out of it. I think it was in "Flight Bows" somewhere.

I went back and looked at that thread...and I'm wrong about the power lam.  According to Alan "A “powerlam” or double wedge in the handle between the belly and backing layer risks reclassification as a Complex-Composite."
