Study your limbs at full draw and see where YOU want the more bend to be. Taper trapping away from where where you want the bend back to a rectangular limb. I generally mark 1/8" in from edge and take that off being sure to not make a sharp edge on other side of limb, that will ding easier. So I leave the glass and a bit of wood lam still square to face on the narrow side. When you round the glass you will get close to the wood lam anyway.
I made a jig for my disc sander to get started but it is easy to get too deep. I would use a light rasp and files then a sanding block to do the first one or two.
Keep these pics and overlay the new ones on them if you are techy enough to see the change and plan the next one...
Or send it to Roy and tell him what you want, he likes sniffin glass.
