This is a multi-part message in MIME format. ---------------------- multipart/mixed attachment Two totally unrelated subjects...... Can someone with a good understanding of impact hammers and stability explain to me how to "get stability" and "recognize it", using an impact hammer? Please feel free to mail me off-list. It's a different animal than a regular hammer, I know, but I can't quite figure how to figure it out........ I tuned the tightest "pin block" I have ever seen today. It was so bad that when I finished my muscles were just beginning to cramp.... It was a 1930 Wurlitzer baby grand, and when I put the hammer on the first pin I was simply shocked. No Baldwin was ever this tight............ It was quite by accident that I discovered there was no pinblock, but this was using the plate as the block. The tuning pins were slotted from the bottom, each having a wedge driven into the slot, much like a wedge is driven into the handle of a "regular hammer" to hold the handle on by the outward pressure caused by the wood. Does anyone on the list know the history of this notion, how it started, why it ended. It was utterly fascinating to tune. Couple loose pins, I simply tapped the wedge a bit tighter. There would be no wearing out, though it was tough on the muscles......... thanks for any info. les bartlett ---------------------- multipart/mixed attachment A non-text attachment was scrubbed...
