Title: heat treating a lam bow?
Post by: Aries on April 06, 2010, 02:41:03 pm

Hey i had a thought i thought id run cross the pro's.   I was  about to begin makin another bbo, and started thinking ::).

  we can heat treat the bellies of our self bows to boost performance, could we also do this with a lam bow.  I think there would be issues with heating the belly if the wood was already laminated because of the glue(im not really sure on that), so what about heat treating your belly wood before the glue up.  I dont really see why this wouldn't work. Do you think there would be any significant boos in performance, and what issues would I have to keep an eye out 4 if attempting this?  Thanks guys. Ty

I did a makeover of a hickory backed yew bow to redo the R/D profile. Used a heat gun. Worked pretty well.

While were on glues... What about gorilla glue, it sure does make a mess if you dont keep an eye on the expansion, but it has a heck of a hold in my experience, do you recon it would be strong enough for a backing job? Ty

Hey Ty
Living in Arizona, I had some problems with a few home projects using gorilla glue. Arizona=mega heat! But that wasn't wood.
Give it a shot on a couple pieces of scrap wood, see what happens.. Once again, never tried it on wood.

Gorilla glue is not suitable for heat treated bows, its fine for just laminates with no heat treatment. Last bow i made I used it, I noticed the glue started melting where I applied heat. Luckily everything came out ok but I wont be using gorilla wood glue anymore.

the white gorilla glue is ok, but the original foams and expands, leaving air bubbles in the glue, bad things will happen

true on the bubbling effect, i could definitely see that causing issues.  I have successfully (probably luckily) glued together several handles and 2 bamboo backings with it. I think with the risks involved it might not be worth using for future projects.   

Does the glue used affect the amount of set a bow will take or performance in any way? Im sure it would effect performance if the glue failed of course ;D

aries, not sure about performance, but the r/d you glue in sure does
