Title: Pyramid design
Post by: AJackson on January 05, 2011, 09:12:00 PM
I'm building a bow for a friend and I have decided to go with a pyramid design. He was hoping for 60-65# at 29". I will be using white oak with hickory backing. Just wondering what a good limb thickness would be to start.

wood bows is nothing to fiberglass bows...just remove wood until it begins to bend.

Densities vary from board to board from species to species...I wouldn't go by dimensions

70" NTN, 2-1/2" wide, 1/2" thick belly slat, 1/8" backing should be close to start.

Wood is wood you can get poundage by maying your bow to messured thickests.
 Built a tillering board with a scale. This way you get the poundage you want to the draw leanth you want.
