Yes, I ground my own lamps...they are identical. What that question did bring to mind is, there is a.002 taper jam and a .001 taper lam in each limb. One is on one side of the wedge and the other is on the opposite side. If these were to be the other way around in one limb, I wonder if that would effect it???.
I had thought already about the straight edge on the limb pads thing. I noticed that when I traced out the riser that two straight edges do not meet in the center of the riser. They meet about 1/2" above center. My riser is the same.
