This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Dave, we used to use in the shop what we called the "lazer tool" If you'd like I'll try to find the plans for it (or someone else might already have some) Basically, it is a pair of tweezers with low voltage running through them. You "pinch" the tweezers over the ends of the pin, and vuala! You've loosened it. The current through the pin causes it to heat up, and thereby presses the felt inside, almost like ironing it. I know I know, it has nothing to do with lasers, but that's just what we called it! (because of the hum it created) But I tell ya, I never have had the effects wear off (seems to be stable), and I've found no better way short or repining everything to fix a whole batch of tight pins. Anybody else with such experience?

It was a Kawai console that was in a room approximately six feet from an open window. It IS January, and even though this is California, there was a substantial amount of cool, damp air blowing in from outside. After a brief and kindly lecture about the evils of drafts and temperature/humidity fluctuation, I set to work. There were many sticking keys and sluggish hammers. It was tight centers, so I figured, hey, CLP will do the trick. I was wrong. For whatever reason, there was no noticeable improvement in the sluggishness. I assume that none of the excess fluid gets absorbed by the plastic as it might get absorbed by wood. Anybody know for sure? I reamed a few flange bushings and replaced some corroded pins and the situation was resolved, but a less time-consuming solution would be desirable.. Anybody got an answer, and/or a lubricant that might work with Styran? Dave Stahl ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
