Hello All: I have taken a square grand action into the shop to regulate, and am stumped as to how to efficiently regulate lost motion. In particular, how does one get to the rocker capstan screw that is underneat the hammer rest rail? My offset screwdriver doen's fit in there very easily, and a straight screwdriver doens't work very well eithere. Anybody have a suggestion? Thanks, Patrick C.
