[pianotech] WNG plate bolt installation

Hi Will,

I do stepped stuff from the inside out rather than the outside in. How 
about center hole first, then make yourself a piloted paddle bit, the 
pilot slightly smaller than the 13/32 center hole with the outside 
diameter ground to the 9/16 required size. Then a 9/16- piloted 7/8 hole 
saw for the head.

You've probably got everything you need underfoot in the shop already.
