Making lamination

[mzombek]

Hi, been awhile since I posted. I am in the process of making laminations for my longbow. I have a 2 part question. When making tapered, I assume that when making a .002 per inch lam, the thickness will be .072 at 36” long? Would there be any reason to make the lamination longer than 36” to get a thicker taper?
Also, can 1 parallel lam be used to get the stack thickness or should several lambs be used?
Thanks in advance

The difference end to end will be .072” on a 36” lam

I won’t go under .080 butt to stay outta my sled

You can just make the butt thicker up to say .125 and the thin end should be .072 less than butt

More lams are better IMO but there have been one lam bows made

Good advice, there is little point to cutting it that fine. You're always going to need some thickness at the limb tip so there is no good reason to taper to zero thickness on a lam.

+1. Thinner lams conform to the form easier and have less spring back off the form. The downside to using more lams is more to grind and more chances to have errors in thickness creep into the stack.
