Title: Wood Bows Made Like FG Bows?
Post by: mmattockx on December 24, 2020, 12:31:12 PM

Does anybody here make their wood lam bows like FG lam bows, with a captured riser block and the back and belly lams running outside the riser? This is what I'm attempting with my current bow and it would be nice to be pointed towards some threads talking about this approach and to see the results from others.


Thanks,
Mark

I do. I build bamboo backed and bellied tri-lams. The bamboo belly lam runs up the fades just like in a glass bow.

Sweet, that looks great. How much tillering do you do after the glue up? Any great tricks or problems to avoid that you have found?

Thanks Mark. I build it much like you would build a glass bow. I taper all three lams and the power lam and I cut the back lam to shape before I glue it up. It shouldn’t need much tillering, but since its made of all natural materials, it can be a little off. Tillering can only be done from the sides on this type of bow.
The only real difficulty I have during glue up is getting the bamboo belly lam to conform to the fadeout ramps. It takes some careful sanding to get them to bend backwards. Clamping them can also be tricky. I use the strongest spring clamps I have there.

Beautiful work Dave! How does the bamboo back/belly bow compare to a glass bow of the same design?

The bow in the picture drew 65#@ 28” and shot a fast arrow. It performed as well as a glass bow and was nearly silent. The only real disadvantage is durability. Glass bows are a lot tougher. This one popped a big splinter on it’s back. Right now it’s waiting for me to get to work and grind off the back lam and put on a new one.
