---------------------- multipart/alternative attachment I have always been pretty careful to have the rep lever pinned also somewhere between 6-7 grams. Pinning of course if a whole "nuther" subject but consistency is the key. If the rep is too fast then the spring naturally gets regulated to a more weak position, and on Steinway whippens affects the jack return ability. If the spring is too weak the jack is slow. In my experience the only way to get better repetition is to increase the friction of the rep pinning. All of this can get muddled if the spring slot is full of gunk and not milled properly. My recent complaint about the milling of the slot is that too many of the new ones that I see have some roughness that has to be removed and then relubricated. Also occasionally the springs are too long in the jack causing it to hit the back of the jack, slowing things down considerably. Ok, I'll add that if in regulating someone has pulled the springs out to the side too far that occasionally the spring will be riding at a slight angle in the slot with the front and back of the curve of the spring riding on the sides of the slot instead of the center. While I'm at it, I also resurface all the NY parts on the repetition lever window and the jack top, front and tails. I use 1200 paper and then reapply a lubricant like McLube. If you use an old fashioned burnisher for this after the paper you will crush and harden the surface of the jacks and reps making a very smooth surface which I have found is very noticeable by pianists. Oh well could go on but .......TP ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
