<html> Hi gang, The broaches sold by Schaff piano supply are my invention, although in reality I merely refined something that someone else had shown me, and worked on a procedure to make flange repinning accurate, stable and quick. These are straight smooth wire, pointed on the end, and roughed up in one area near the handle.  They come now in 8 sizes to use with most of the center pins you will need to put in pianos. American Piano Supply used to sell something that was similar, but the roughed-up area was much too rough to work correctly.  I tried many times to get them to fix them, to no avail. They left the bushing too chewed up.  Since Schaff bought them out, they don't make the bad ones any more. Herb at Schaff told me that he has sold a lot of the broaches to other piano suppliers in other countries, so you might see them for sale elsewhere - I think I saw that Pianofile in Canada has them.
