Hi William, Did you not have to grind off the threads of the new bolt to match the old one?

Monroe" <bill at a440piano.net> To: <pianotech at ptg.org> Sent: Tuesday, July 14, 2009 8:48 AM Subject: Re: [pianotech] Front rail pin extraction Court, I modified a pair of Vise-Grips for pulling sundry tight "thingies." I replaced the original adjusting knob with the same diameter threaded rod with two nuts and a lock washer on the end - about 12" in length. I added a weighted slide (from Joe Goss - but any solid heavy sliding weight would do) and voilà - now you have an impact removal tool. William R.
