Letoff rack needed

[Farrell]

I own and have used the Spurlock jig many times. I also have a jig very similar to the #999 "Grand Let-Off Rack" on page 66 of the Schaff catalog (mine is home-made). I use both. The Spurlock jig is excellent and all you need for in-the-piano let-off regulating. Assuming your hammers are bored consistently and the strings in the section are in the same plane (perhaps a big assumption on some pianos!) the Spurlock jig allows very easy, very fast, very exacting let-off adjustment. All you do is regulate let-off on two end-of-section notes and then use the Spurlock jig to set all other notes in section to match.

For bench regulation, I like to also use the wooden let-off rack. Maybe related to my relative inexperience, I value being able so see the string plane. It helps me when I am trying to determine an optimal hammer line height, observe and measure drop accurately, etc.
