tapered lam question

[breazyears]

I have been making tapered lams for a while. I always bring them from the big end to zero. does this matter? can they be .072 to .036 for example on a .001 taper. I also measure the thick end for the stack. will that change if they are not brought to zero???

No, they don't have to go to zero. Most don't. If I'm making a light weight bow, do the math, and the tapered lams will be too thin on the thin end, i'll use less number of lams and make them thicker. But it all depends on how it breaks down.

Stack is measured at the butt end regardless, and the lams are tapered to whatever degree you need to get the limb action you want.

I don't make glass bows. But for wood tri lams, I taper the tip to 1/8 thick or 1/16 thick, depending on what I need. I feed the tip end into the sander first.
