Shooter, I'd glue the first Ipe strip to the Pecan backing, and make your bow no wider than 1 1/8" wide and glue it up in either slight reflex or r/d neither with more than an inch of reflex. Then I'd add the second strip after this has dried and you have a clean bow outline. Then I'd glue the second strip on the belly and just lightly bump the reflex a hair more than how the first one is at rest..
You will store a bit more energy, and have enough wood for a 60# bow give or take...
This is a cool thread!
