Bamboo, I agree, it wouldn't be enough thickness to affect the same change as a true power lam. I was only trying to clear up what others were saying.

So on your design a powerlam would be a .002 taper going each direction from center about 11 inches long for a total length  of 22 inches???????
And how thick would it be at center????
I hope I'm not asking  to much .

A power lam has to taper to a feathered end from center toward tips of limbs. It can be variable in starting thickness. Say for 11 inches, I'd go with at least .004 per inch, coming to a feathered end just like a fade on riser.

This would make .044 thick at bow center. It could be .060 just as well, or thereabouts.

I like it to be tapering when it goes past fades of riser, but from there to center it can be parallel  because the riser is handling it.

Hope that helps!
