"scrunching" in an SF10

[Keith Roberts]

The rail was loose right? Are the let off screws tied to the hammer rail? As
you tightened up the screws it must have changed the let off position.
Hammer blow distance lessened too? The rail must have rotated down on the
hammer side, pulling up on the front side.
