Okay, thanks for the link. I watched the video of the russian guy putting cardboard in the pin hole; it seems to me the tuning pins have a coarse thread on the bottom? I thought they were just a straight taper fit.
That lead off to a "why the key sticks" video, which seemed to require less special tools than string replacement. I may take look at the sticky key on the Steinway the next couple of days, that doesn't look nearly as scary as string replacement. I'd best do the sticky key now anyway, it is way worse in the winter and another time of year I might not be able to see what was wrong.
I did actually finally look at the tuning tools page at Steve's piano supply, he has a rant at the top of the page about inferior C****** steel and tools. One reason I've put buying tuning tools off so long, I hate buying anything from C**** unless it is used, and I haven't seen any used piano tools in any flea markets or anywhere that I usually buy stuff abandoned by the heirs of dead craftsmen. The senior coworker on the last job satisfied the requirement to have a full set of tools by buying Harbor Freight imitation tools, and we spent a lot of time trying to drill out wallowed out allen screws or turned off bolt heads. But Steve's will have to wait somemore; I went to the dentist Monday and there is another little $800 problem that can't wait.
