I’m rebuilding a Baldwin R and on removing the corroded and pitted key pins, I discovered that the base of the guide rail pins are 0.177”. The top (swaged) part is a standard 0.146” but the part that is driven in the key frame is oversized. Of course no one has replacement pins like this so I’m going to have to make some modifications. Everything that I’ve thought of so far has looked like a major operation, and will leave lots of opportunity for errors. Has anyone run into this before? What did you do? dave So the new pins are bigger than the holes? Would it be too difficult to ream out the existing holes?
