I just finished one of the same bows from Binghams and I measured everything for future reference.

The wedge was 3/8" thick and the taper started after 2 1/2" from the butt end.

My laminations were:
0.060 - parrallel lamination
0.125 - butt thickness on 0.002 taper lamination
0.050 - clear fiberglass.

It ended up 70# at 28".  So you will want smaller lams.  Check out their website for a guide to thickness.

I must have been typing when Kenny posted his response.  

1/4" difference on the distance from the butt of the wedge.  Hmmmmm.....maybe I measured it wrong????
