Israel,<BR>
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.<BR>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.<BR><BR>Regards
Roger</FONT></BLOCKQUOTE></BODY></HTML>
