sample note in the piano- C4 would be a good one. Set it to the thickness of the
string, or about 1 mm (it helps sometimes to shine a flashlight across the
strings. Pull the action and reset the drop on that C4. Hold down B3 so you can
have a visual reference. Set the drop within 1 mm (1/32”) of your let off. Now
check your hammer rise.<o:p></o:p></SPAN></FONT></P>

down and turn the screw up until the hammer barely comes off the jig rail. That

set on the bench to match what it is in the piano).
