Question for horn bellied bow builders
colin1991:
Ok, for starters, look at the amount of reflex in the limbs of a Turkish bow... You are bending the limbs almost through 90 degrees even before the bow is drawn... I'm talking about using 1-2 inches at either end to create a small curve.
Second, the glue I will be using has never failed on me and I have bows up to 150lbs which are held together using it. It is a structural grade epoxy for use in buildings, joining beams.
As for horn,compressing 8 tines further than wood, are you talking about compressive stress or compressive strain, because there is a massive difference between the 2. I'm aware horn has a massive crushing strength, because of its density and hardness but if it could physically compress 8 times more than wood it would not be any good for a bow because it wouldn't hold any weight.
bubby:
Well sounds like you got it all figured out😕 good luck
mikekeswick:
Yes indeed look at the reflex on a Turkish bow....where is it? I've made a few and have experienced the problems/heartache through thinking I could just do it how I wanted.
I could save you a lot of problems but as Bubby says looks like you already know what you are going to do! Good luck to ya!
colin1991:
Is there any curve in the limbs forward away from the direction the Turkish bow is draw when it is un braced, yes. Therefore it has reflex in the limbs. Just looking at photos of your most recent build un braced id say the limbs are reflexed heavily and also recurved slightly at the tips...
No need to say things I want to try WONT work when you have not given any reason as to why... For example, why won't Mass work as a core? Its very strong in shear and bending and wont fail in my design. It will also allow for some pre tillering before I add the horn layer to the belly.
loon:
Most (but not all) of the reflex in horn bows is at the kasan eye, tip, and sometimes grip. Turkish bows usually don't have any reflex on the bending limb (except on the kasan eye?) unless they're flight bows? Well, war bows don't.
Massaranduba might work, but if it's an oily wood there's a chance of delamination and you might have to treat it somehow
