List, Have any of you noticed the correlation between difficulty of rep spring regulation and amount of green goop in the rep spring lever slot on Steinway actions? I've been regulating an L, using a technique taught by the great John Hartman, whereby you use a small 1 gram (or so) weight which you clip to the strike point of the hammer. When you set each hammer to 'just barely rise' from check, you get consistent spring tension, and a very even 'speed of rise' difference from bass to treble. It has worked well for me the few other times I have tried it, but on this one, despite my best efforts, they end up working a little inconsistently. Is it the green goop? This piano seems to have quite a bit of it. I know that it is a special secret formula mixture of moose earwax and equatorial pond algae designed especially to aid in repetition, but I was also wondering whether anyone makes it a routine part of regulation to clean this out, and replace it with graphite, Protek MPL, VJ lube, Chapstick, etc. I know it would only help to replace it, but exactly how does one do this quickly and efficiently? It's not in this piano's budget to disassemble to clean, or is there an easier way? Ken Jankura Newburg,PA
