<html> Removing material from the wippen heel is not going to make a significant change in touchweight. The effect of Key Ratio reduces that weight at the front of the key, so if you remove 1g the resultant weight reduction is 0.5g.  KR is approx. 2:1, but Strike Weight Ratio is approx.5:1, so removing 1g hammer weight lowers DW by 5g. And more significant is replacing the knuckle further out on the shank. I've found that wippen material removal is not worth the effort. Been there, done that, Jon Page PS  Wally does come through with speedy service.

(and narrower too) At Arlington, in the rebuilding workshop, someone suggested I take material out of the wippen heels.  In doing so, my homemade jig didn't work too well on the first half dozen or so and they split open at the place where the dowel is inserted at top.  I called Wally in a panic and he said he didn't know if he had any "loose" ones, but would look.  Three days later, there they were in my mailbox.  Now THAT's SERVICE!
