I am going to build a hill style bow and looking for a target stack up and taper. I made one before from bingham's chart & ended up cutting down to 64" to get weight.
Plan is for 68" nock to nock, 45# @ 28", 15" riser, around 1.25" at fades taper to 0.500 at string nocks. Can use 0.03 or 0.04 glass.
Appears the hill style bow centerline is 3/4 to 1" off riser centerline as well.
Any input would be appreciated.

These might help you out, but I use a 16" riser and 0.05 glass on the first build along and 0.04 glass on the second one.

John thanks for the reference. Great read and a lot of info. So with the 0.04 glass how much would you reduce the stack for a 45# bow (0.01 reduction??)
Also are your limbs the same length from centerline of the riser? (Or from the fade outs) to the string nocks?

Based on that bow I made with 0.040 glass, I'd say 0.435 for a total stack. If it ends up a little heavy, you can narrow the limbs a little to reduce weight.
Yes, my limbs are the same length. Once I get a string on it, I check the tiller. The majority of the time one of the two limbs will be a little bit stiffer (1/8" to 1/4") than the other and I then designate the stiffer one the bottom limb and finish it on out from there.

John, thanks for the info. The bow you built look great! I am going to give it a shot & see how it comes out.
