TriLam dilemma

[Wolftrail]

Just took out a R/D tri lam from the form today. 1 1/2" wide maple belly & back, white oak core.  Its about 67" before cleaning it up.  By the time I get a handle glue on it will maybe make 30#  I want at least 46-48# out of it.  Not sure what the thickness is but what is the best way to go for increasing the weight.  I know, lost and confused.         :eek:    

Glue another lam on the Belly or Back..?
Maybe increase by some other method like glass..?
...my intentions from the start was to make a glass bow...Never made one...........

If you just took it off the form, and are not sure of the thickness, then how do you know it will only be 30#?

At 1.5", if it's at least 5/8 thick total at the grip/fade area you're probably looking at around a 50# fully tillered bow.

If you need to increase weight,  you can add another belly lam or sinew the back. Sinew would add insurance as well as weight.

I would wait till the riser is glued on, then see what the weight is. Then I'd do a belly lam glue on of at least 1/8th thick, maybe 3/16th. Or making it 60" long will bring up the weight.

What draw length? You could possibly cut enough length off to hit weight.

If not feasible, you could either put a glass lam on the back or an osage lam on the belly and continue on.

Are any of your lams currently tapered? If so, which ones and how much?

I have built over 12 bows, I have a feel for it now. As far as no handle goes. I simply clamp a short block in the riser section and test bend it. Easy Peasy...!

Thanks Roy, I will commence soon.  Sicker than a dog lately,  makes for some dumb mistakes.

All lams are Parallel. Draw length will be 27"
