Lot of work just to save a buck and not much chance of it looking great arround the pinblock area. If you try it be sure and use the Red Hot Stuff from Dryberg.</FONT></DIV> <DIV><FONT face=Arial size=2>With the situation you describe you might consider:</FONT></DIV> <DIV><FONT face=Arial size=2>1. Loosen 1/4 turn and treat</FONT></DIV> <DIV><FONT face=Arial size=2>2. tighten all pins 1/8 turn and retreat</FONT></DIV> <DIV><FONT face=Arial size=2>3. wait overnight</FONT></DIV> <DIV><FONT face=Arial size=2>4. start at A0 and tune to the top retreating any pins that seem on the weak side.</FONT></DIV> <DIV><FONT face=Arial size=2>5. fine tune</FONT></DIV> <DIV><FONT face=Arial size=2>The moisture from the Garfields will cause the CA to set up, so you do not need to zap.</FONT></DIV> <DIV><FONT face=Arial size=2>The 1/8 turn will break the glue collar and allow another application.</FONT></DIV> <DIV><FONT face=Arial size=2>Do remove all felt from under the coil.</FONT></DIV> <DIV><FONT face=Arial size=2>I hope there are plate bushings, the CA works better by joining the bushing to the block,</FONT></DIV> <DIV><FONT face=Arial size=2>``````````in effect deepening the grip on the pin.

The piano is not great but has been maintained reasonably. The customer is not a player but likes the way it looks in her house and would like it to be able to hold a tune. She, of course, wants to do this as cheaply as possible. The pinblock is shot and evidently has been so for over 20 years. Someone treated it with "Pin Tite" over 20 years ago. I've searched through the archives and have found a bit of encouraging posts about CA being somewhat effective on "Pin Tite" treated pinblocks.<o:p></o:p></SPAN></P> <P class=MsoNormal style="MARGIN: 0pt"><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-bidi-font-size: 12.0pt; mso-ansi-language: EN-CA"> <o:p></o:p></SPAN></P> <P class=MsoNormal style="MARGIN: 0pt"><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-bidi-font-size: 12.0pt; mso-ansi-language: EN-CA">However, the problem I see is that the pins have been driven in so the coil sits right on the plate. There are also those felt bushings between the coil and the plate but they are quite crusty and with a little bit of work they can be removed. The pinblock is quite thick so the tuning pin holes do not go all of the way through so it can't be treated from below. There appears to be a tiny bit of "daylight" between the coil and the plate at the front of the pin and it seems possible that I could get a smallish syringe needle in the gap to treat with CA. <o:p></o:p></SPAN></P> <P class=MsoNormal style="MARGIN: 0pt"><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-bidi-font-size: 12.0pt; mso-ansi-language: EN-CA"> <o:p></o:p></SPAN></P> <P class=MsoNormal style="MARGIN: 0pt"><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-bidi-font-size: 12.0pt; mso-ansi-language: EN-CA">My question is, has anyone ever had a similar situation where they had such a tight access to treat the pinblock?
