IMHO, it depends on your objective. If the objective is to have optimal and consistent friction pinning, then you should repin. If your objective is simply to return function to your fleet of 40 year old consoles, then by all means, push the pins back in and lock 'em down. Be very careful pushing the pins back in because you can disturb the felt bushing and cause excessive friction - or you can even push the entire bushing right on outa thar - well, I have a friend that told me that happened to him........

  Subject: center repinning question


  Hi all - 
  This seems like a pretty beginner level question, so I'm almost embarrassed to ask. I'm working on a small fleet of 30-40 year old Yamaha consoles. Most of them have center pins that have walked out of the butt flanges. However, I'm finding that since these all have the metal tabs on the hammer butts, if I just press the pin back into the joint and tighten the tab screw, it's a snug fit. No wiggling back and forth, and at most I'm getting 5 swings. I don't want to assume anything and shirk off what needs to be done, but at the same time, I have other things to do than repinning if this indicates that it *doesn't* need repinning. Am I making sense? I have a lot of repinning experience, my earliest training was actually with a school full of P22's which did not have the metal tabs, but had a bunch of repinning needed. Can someone give me a little quick clarity on this? If the pins have walked out is it an absolute that they should be repinned, or is it just a case of no one ever tightened those metal tab screws? 
  Thanks!
