BBI verses BBO

Mad Max:
 :OK

mmattockx:
This is based in ignorance of this particular combo in an R/D bow, but I would say your ipe is too thick. Unless you are going to remove a bunch in tillering, in which case it is probably OK. You only need a thin layer of it on the belly to carry the big compression loads, especially with an osage core that is very good in compression as well. If you had a maple core then I would say maybe 3/16" ipe, but the osage doesn't need that much help and a 1/8" belly lam should be enough for the load and would keep the limb weight down for more speed.

It has to be scraped for tiller. Bamboo has nodes and some dips also.
BBI means Bamboo and Ipe, mine is a tri lam to keep the Ipe thinner.
If I made them all the time maybe I could get the Ipe thinner.

Pat B:
Mark, have you talked to Roy. This seems to be his expertise.

Yes, I'm building off his form design and he gave me a stack height, I reduce the stack some because of the Ipe.
Same Ipe I gave you, any plan when you are going to build?
It was good to see and talk at the classic  :OK
