A friend gave me the form for the limbs- don't know where he got the plans but I do know he makes changes to any plans he gets. The riser was based off of what I thought would work. I use smooth-on for all my glue ups- as for glass I use Gordon Bo-Tuff E Glass, UL (Uni-Laminate). The bingham plans will make you a good bow- the riser can be shaped to your liking- lots of good info on this site.
