what wood to accompany bamboo and osage?

[Pat B]

Not much of a taper there, tooch.      
I assume you mean taper from 1/2" to 1/4"

[tooch]

No i meant what I typed.  Not much of a taper at all indeed.  On both there is one side just over 1/4" and the other side is right at 1/4"

[Roy from Pa]

1/4" thick Osage will be fine for the belly lam. But for a bow in the mid 30 pound range, you want to add a core lam of about 1/16th" to 1/8" thick.
