I know this has prolly been covered before,but what does everyone like to use as far as thickness of wood to glass in a longbow?I seem to use about 25-30% glass,was wondering if I could go with less glass thickness?
Anybody? :help:
I seem to remember some big builder saying he thought 20-25% gave the quickest with the least amount of handshock. My 50-58# bows ran 25-28% but I'm no big time builder.
Thanks Galen,how ya been?
right now I am in the process of making the limbs I have the wood cut two oak, one walnut staves per limb. Not yet glued so if if I followed the twenty percent rule I could laminate the back and belly Question posed to you Is this a percentage of product or total weigtht
Jerry
I was meaning % of thickness as in .400" total thickness,the glass would make up .100" for 25%
You could ask Binghams
Kenny, I heard somewhere are either read that if you used less glass the bow would be smoother and faster. Heve`nt got a clue but I been thinking bout trying the theory out.RC
Dan,I was thinkin that too...
RC,thats kinda my theory too,how low % were you thinkin? Gonna build my wife a hybrid,might be a good place to try a lower percentage,bein a lightweight bow........I'm thinkin 20% glass if I only knew what total thickness for a 35#er :knothead:
Kenny,
What kind of 35#'er are you making?
My TD longbow was .050 glass on both sides with a .060 parallel and a .120 taper action wood lams and that comes out close to 36% glass. Use those two lams with .030 or .040 glass and you might be close. My bow is the pronounced design with but a little shorter with 16 inch riser and I think 1 1/2" each shorter limbs.
It was fast until, as you know, I blew up the riser. An action wood riser block should be to me this week. I will be hunting with that bow this year!
Steve,mine is gonna be a 64" 1-pc,with a 17" riser.I think if you had wedges that would make your riser a little longer. I made a 45#er off this form so I've got a plan,but I read somewhere less % glass is less stiff too,so there is the big guess!!
