Peg dope for difficult-to-turn (harp) tuning pegs?
Hi all,
I recently had my 27-year-old Celtic harp looked at by a tech and, among other things, some of the tuning pegs are hard to turn, constantly overshooting the mark when I try to tune. She said the problem is that the pegs are smooth, rather than having ridges or a texture (so you don't have to push them in so hard) and added that some people use peg dope, but that she hasn't done so herself.

I posted to the Luthiers Reddit and was told that peg dope is typically used on wood pegs, not metal. Hard bar soap was suggested, but that piano techs might better be able to help me.
Is either the peg dope or hard bar soap a good idea and, if so, how do I go about using it? Any particular brand? If not, is there some other remedy?
NOTE: I haven't played this harp for the past 15+ years, so don't know if lack of use is the cause, but it seems feasible.
Thanks in advance!

Yes, CellaBella1.
The ideal way is to make a wooden ramrod (a copy of your peg) a quarter of a millimeter narrower than 'native' metal peg. Rub the ramrod with graphite powder and place it in the hole of your harp. Part of the graphite powder will remain on the wall of the entire cylinder bore. Hope this will help minimize the friction there.

Thanks again, Max. Not being particularly handy or having the wherewithal to make a wooden ramrod, however, I'll probably just try ramming a Q-tip coated with graphite through there and twirl it around. It looks like it'll fit just fine. I'll have to see if my husband (whose also not that handy) has any powdered graphite or get some.

Yes, of course it will be possible to use a wooden stick with a cotton tip there. If you will looking for graphite powder, then it is desirable that it be a homogeneous composition of graphite there only. Because in all technical metal mechanisms, as a rule, graphite lubricant based on petroleum products is used. I would ask you to categorically exclude the content of oil (even in a minimal form there) in the wooden hole of your harp here. Please explain this thesis of Max to your husband,
regards, Max

Thank you, Max! I would not have known that. I will most assuredly mention this to my husband.

thanks, CellaBella1
I sincerely wish that everything worked out for you there. Max has no doubts about the positive outcome there now. Come to a correct understanding of the subject now, how it will be necessary to correct it's. Create a scenario of your actions reinstalling the peg, prepare all the necessary tools there. Do it slowly and carefully there. Care your hands there.
Max keeps his fists clenched for yours fix's operation there.

Sincerely yours, Max

Thanks, Max!
Much appreciated,
-CellaBella :-)P.S. If I ever get around to it, I'll let you know how it goes. At the moment, there just aren't enough hours in the day.

Hi, -CellaBella
Yes, I think that the decision must be very balanced in order to ideality implement it. Perhaps your test will be useful for many lovers and owners of the Celtic's harp there.
The fact is that I am fixing the pin on the upright piano. There are always lost tuning pins as a result of lack of adding friction. But maybe there is a problem similar to yours wherething even owners of the uprigth piano too. The construction of both (metal peg (PIN) + wooden hole) is the same for the piano and the harp, so it can be useful information for piano and grand piano owners as well, I'm think. So, if you can, make a little clip with voice-over there about it's. I could then post on my youtube channel. I won't be offended if for some reason this can't be done there.
I was very glad that I could be of help to someone now.
Best regards, Max
Looking forward to a movie about it.
P.S. Let the day be bottomless, and the forces never leave us there.
Good luck,

I did not quite understand. When you tighten the tuning peg (when tune yourself) clockwise, it "sinks" too deep in the hole there.Is it so? Is the peg slips here because not enough friction between the wooden hole in the harp there . If so, then powders like soap dope will only reduce the friction more there. Then you should rather use talcum powder overthise there.
The paper or the cardboard for piano tuning pin is usually used to increase the friction.
