What are you guys using for plate relocation in the soundboard area? I've been drilling two 1/4" 90 degree holes (one at the bass end of the tail, the other at the treble end) through the plate, through the panel and into the rim; and then using 1/4" drill stock as pilots. Are you doing something similar?

After marking through the plate I use a forstner bit to countersink giving some room for the nut below the level of the board. The forstner also leaves a centering mark which I then use as a guide for the drilling the hole for the socket screws.

You don't want to get the piano strung and then discover that you need to lower the plate tail a bit for bearing, but can't because of the nut. That sort of negates the overall convenience of the system. Ron N
