NIck: Perhaps I'm misunderstanding your intent, but are you wanting to replace these agraffes? If so, why? You'll have to do the same to the new ones that you can do to the old ones, if, as you say, they are essentially undamaged (pitting aside--that can be polished out).

Still, I couldn't get the gage's 32 or 36 TPI to line up right with the threads. The standard 1/4" stud just falls in the hole. A prior tech removed the originals and "cleaned" them up by sand blasting, or so it seems by the slightly pitted appearance; otherwise nothing is bent or weird looking. The string holes have not been touched or redressed. Pianotek does not offer this size (that I can see from the catalog), neither does Schaff. The idea of plugging and re-tapping for standard agraffes is, of course, possible but relatively time consuming, and there is no room for error. Anyone replaced these recently, and if so with what? Any reconditioning anecdotes worth sharing?
