tri-lam warbow

(1/4) > >>

luke the drifter:
i am looking to get materials together to make a tri-lam warbow.  i thought i might try Hickory for the backing, White Oak for the core, and Osage for the belly.  any pros-and-cons with that combination?

adb:
I've never used that combo, but I don't see why it wouldn't work. I usually use hickory, ash, or maple as a backing. Mostly, I'll use a dark contrasting wood color for the mid-lam, like bloodwood or purpleheart. I think osage is the best belly wood for heavier weight laminate warbows.

I made a tri-lam warbow about a year ago... hickory back, bamboo core, and osage belly... 100#@32". Turned out fine, but you couldn't really tell it was a tri-lam. The hickory and bamboo are basically the same color.
I finished a tri-lam just his past fall... ash, purpleheart, osage. I think it looks good... you can really see the layers.

Make your backing and core lams 1/8", and then that way, you'll have enough bely wood to make weight.

Ian.:
Ive used white oak before and backed it with ash to make a 130lb bow, to be honest its not good enough to warrant putting in between Hickory and Osage you wont increase the performance, what weight are you going for?

Pat B:
Isn't the core lam basically a filler with not much performance value?

No! Absolutely not! The core material is integral to a tri-lam! 'Just anything' will not increase performance in a tri-lam. Certainly, the core material is not as important as the back or belly, but it still matters.
