Title: Quad lam build...
Post by: Roy on March 01, 2014, 11:19:35 pm
Osage tapered belly lam, Red Elm tapered core lam, Osage tapered core lam, backed with a tapered piece of bamboo, cocobolo riser and cow horn tip over lays. 58.5 string groove to string groove, 53 pounds at 28". 1 1/4 wide at flares and I hold that 1 1/4 width out another 6", then a straight taper to 1/2 wide at tips.

After the lams are glued up and dry, I lay the riser block on it's side and trace out the profile of the bows riser section on the riser, then cut it out and use hand tools to get a perfect fit, then glue it up.

I also flip the tips of the belly lam before glue up. And I end up with a sweet looking bow.

All done on the tree. Top limb is to the right here. I synced, timed the limbs so it has a negative 3/32 tiller.

I have neer done a lam bow so forgive me, but whats the difference in tri and quad lam performance wise? I was led to believe a backing is for tension, core for power, and a belly lam for compression strength. Is the forth for looks or is there another function?

Its a beautiful bow and I wouldnt min gettin my hands on one!

Man Roy your bows are first class for sure.

I used 6 inch end posts, 2 3/4 inch mid limb posts and a 3 3/4 inch center post. The mid limb posts were placed half way between the flares and limb tips. Quad lam just has 4 sections glued together. I used 4 because the belly lam I had was not thick enough to get the weight I was looking for. I doubt if there is any performance difference.

Thanks guys..

Sweet bow Roy, that thing looks perfect at full draw. Bet it really flings an arrow when those limbs come home on release. Good looking bow to boot, nice!
