[CAUT] vertical hammers

[Ed Sutton]

It can be done well on the bench, thus:
-Note blow distance in the piano.
-Set up action on the bench in an action cradle.
-Attach bolts (about 1/4"x3") through the action bracket slots.
-Cut strips of plywood to approximate the string planes, bass and
tenor-treble.
-Drill holes to attach the plywood to the bolts, use nuts and washers to
mount the boards at the blow distance from hammer rest line.
-Put masking tape on the boards at strike point line.
-Press old hammers against a stamp pad, then press them against the masking
tape, printing an index of the string spacing and hammer spacing.
-Remove old hammers and replace as in piano.
-It is also possible to superglue a support shelf on the boards to assist
in maintaining hammer alignment.
-If you have lots of pianos of same model, save your index boards for
re-use.
