Removing grand plate drilling more holes?

[Newton Hunt]

Is it maybe possible to use some of the _ 240 holes that are pre-
drilled?

 Cyrillus

Yes it is possible, but they are larger and errors are easier to
commit.  Tiny holes are easy to hide as well.

You may see some pianos that have holes drilled in the plate rim the
size of tuning pins.  You can use these holes or drill your own to fit
the pins you have in the shop, but I prefer drilling the tiny holes in
the corners of the plate and pinblock.

By measuring from these holes to the stretcher and to the rim and
writing the results on the keybed it is possible to fit a new block to
the plate, drill the holes into the new block from the plate, lay out
cutting lines with the proper angles derived from the measurements from
the old block holes, cut the block, drop it into the case and the plate
will find it's own location.

Easy, simple, elegant and functional.
