Joe,
If you are not having any noise over the long term, hey sounds=
 good.   The whole idea is to eliminate the rubbing of the top=
 and bottom of the pitman against the tray and lever.  I still=
 visulize rubbing in your retro-fit.   The punching works similar=
 to the Baldwin setup and eliminates any rubbing.   I've never=
 had a customer mention any concern with the hole in the bottom=
 of the piano, but I think if they were to take a look under the=
 piano they might just see some other holes already there and the=
 piano seems to be OK...;-]   
I take it your removing the bushing cloth in the original hole?  =
 Never having any clearance problems?   I will admit drilling=
 under the piano is a pain with sawdust in the face...

   Me, I retrofit using a brass =93dowel=94 with pins on both ends.=
 Dowel cut from 1/4=94 (or so) brass rod, pins are bridge pins=
 driven into appropriate holes. Saves the trouble of drilling a=
 bigger hole through the keybed (I first did it when a customer=
 freaked out at the thought of drilling a hole in her piano. 
    The wood dowel with punchings glued on each end works great,=
 perhaps better than a pinned dowel. But to save time and effort,=
 I found going to a smaller diameter pitman and adding pins was=
 quite adequate for the purpose. Brass rather than wood because I=
 didn=92t trust the strength of smaller diameter wood.

A mind is not a vessel to be filled, but a fire to be kindled.
