Pyramid design

[AJackson]

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.

yep , thats what youre lookin for.


4est goes iirc , 40-45# at 15/32 limb thickness...

i think the thread says 1/2" for more , but read through all 28 pages , its like a free book.

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.

azn: they do vary , he just wanted a rough idea. and with pyramids you tiller from the side usually...

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.
