Does anyone know what the length of the riser is on the Bingham 60" Recurve?

On the Binghams draw weight chart it states, "measured at the thickest point". Are they referring to the butt thickness of the stack or the stack thickness at the riser fade?

center of the stack, I have built eight of their one piece 58" design. I added a 28" powerlam to the last build and the bow seems to have a little better cast. I also make the riser fades longer than the print..

RR, I measure mine at the riser fades, I called Elmont Bingham and asked because it was clear as mud at the time, he is very easy to talk to.

looking at my log book.. if I have a .252 thick stack measured at the thickest point(center) I end up with a 50 lb 58" one piece recurve, the chart on the Binghams site says .252 stack will build a 45lb bow. I used a digital caliper to measure my lams and glass

Robert,
Are you sanding your own lam's? If your taper sleds are slightly different than Elmont's the poundage wont be the same. When I started sanding my own lam's I had to make my own poundage charts.
I didnt miss, thats right where I was aiming

not grinding my lams,I have bought most of my lams and glass from KennyM.. I have bought some from Binghams too.. I mic the lams and glass every 2 inches before each glue up,I always end up arround 1/8 inch tiller after shaping the limbs. I am using a 002/inch taper. The first build I bought everything from Binghams for a 50lb bow(bow kit), it came in at 56lbs, I sanded the belly glass and narrowed the limbs..got it down to 52 @ 28"..Am I the only one who has to knock a few thousandths off of the stack to meet weight?? The last build I had a .252 stack and added a 030 27 1/2" long powerlam under the 21" riser, I tapered the last inch of the PL from 030 to 0.00, I ended up with a 52lb bow with better cast than the ones I built with out the powerlam. I picked up a couple of pounds over the other bow I built using a .252 stack
