37 steps---delayed response

[Cy Shuster]

OK, I've gotta ask the dumb question.  How does strengthening the repetition springs affect letoff?  Heck, you could *remove* the rep lever and not affect letoff!  Right?

This is great info... can't wait to try it.

  Hi Israel,
                   On the subject of springs. One of the most common causes of unstable regulation, is the friction in the spring grub slot.   I can't count the number of times that cleaning the spring tips and lubricating the slots, has changed the regulation dramatically.   Some times for the better, and some times it will make the springs kick like a mule.  The more I think about it, the more I realize that I either service the springs, or ball park adjust them first, or very early in the regulation process.
  This action will also change let off, and most other regulation parameters.  In extreme cases, ( 1920's Steinway's with Tallow in the grub slot)  you will find that you will need to change the dip (after touch) after you clean the slot and tips.

  Regards Roger
