Matthew Todd asked: "I have been regulating a Baldwin M Grand this morning. ? Have run into several issues to which I would covet your assistance. ? 1.)? Exactly how much rise is adequate? 2.)? I am having a heck of a time regulating the sharps.? The naturals are coming along fine (i.e. let-off, drop, rise).? The sharps are only 3/8'' high as opposed to the specs of 1/2''.? Could that be the problem?? And if so, and increasing the height to 1/2'', how would that affect the dip? ? Before messing with all the sharp heights, I thought I would get suggestions first. ? Thank you! Matthew, You have just described a neophytes approach to regulating! Sheesh! There are several factors that have to be satisfied before one should attempt "Regulation" 1. The action must be in good mechanical condition...i.e. gram resistance in parts must be somewheere in the ball park 2. If the keys aren't right nothing else can be. i.e. keys at proper height and dip...ALL of the keys!!!! key pins straightened and polished and lubed. Good bushings and frame felt. That's the short version. Joe Joe Garrett, R.P.T. (Oregon) Captain, Tool Police Squares R I -------------- next part -------------- An HTML attachment was scrubbed...
