May be using your torch to heat the pins can help them enough to move easily. When the pin have begin to move finish by hand taking care of pulling straight to avoid ovalisation of the hole. I believe it is possible to use a riveting tool, but the standard models are too small to hold the pin (balance pins) . Professional models - air driven - may do the job but are not cheap. Usually pins are very easy to pull off . using a drill I'll be concerned by heat production and big enlarging of the hole. Consider too the R.H. while doing the job, as for pinning, if you are on a very humid period the holding may be stronger (while difficult to ascertain when inserting the new pins) Regards Isaac OLEG -----Message d'origine----- De : owner-pianotech@ptg.org [mailto:owner-pianotech@ptg.org]De la part de Keith Roberts Envoyé : jeudi 5 septembre 2002 13:27 À : pianotech@ptg.org Objet : removing key pins The front rail pins being rusty around the base and swollen are so tight they are hard to even turn much less pull out. They are not drilled all the way through so removing the key frame and driving them out from the bottom is not an option. Any tricks? I am an ex plumber/pipefitter so I KNOW brute strength and dumb luck. I'm considering using my right angle drill. Since the pins are oval I shouldn't have to tighten up the chuck much to get them spinning. Keith R ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
