Core Tuff Glass

[bowhntineverythingnh03743]

So I am going to start a new bow for the up coming turkey season and came up with a question.

I plan on incorporating .030 black core tuff glass into the center of the stack. Running the rest of the stack as normal. What kind of differences would I see as a result?

I am making a solid black riser out of G10, black glass on belly and back, then natural bamboo for the core. I want to do a black theme bow for the ground blind this year as I have had turkeys well within range of just being able to see everything including me raising my bow up to shoot.

Thanks to anyone who gives input on the topic!

When placed in the center of the stack, we count it at the same bending moment as the rest of the core lamination. (Count it in the stack as if its wood). However, it is heavier than the same .030 of Aboo.  

For that reason, we have gone to .015 Stabil Kore.  Get the added reinforcement with 1/2 the thickness and weight.  Very Small diffference, but they add up.  Your results may vary.

I think each bow design will have varying results.
I put black core tuff in the center of my stack on my bow with a stack of .320 and it finished at  51#@28".  Did the same bow with an all aboo core at .330 and it finished at 52#@28".  
So in that design it adds approximately 9-10 lbs with the same stack thickness.

I have a herters recurve that certainly appears to have a layer of black glass under the first parallel lam on the belly side.
The glass is unlike any I have seen. It is textured in appearance almost like a mini carbon weave pattern.
The back glass is brown and the belly glass is black both "textured" and the core glass is black as well. Very solid bow.

I don't see the point in using glass cores. The core only feels sheer and boo ain't going to fail in sheer! the glass is significantly heavier so that has got to have an effect on the return speed of the limb. It has little lateral stiffness increase over the boo either so doesn't even help with limb stability.
It is a no go in my eyes.
