No, the old holes are larger than any currently available pins. dp David M. Porritt, RPT dporritt at smu.edu<mailto:dporritt at smu.edu> From: caut-bounces at ptg.org [mailto:caut-bounces at ptg.org] On Behalf Of wimblees at aol.com Sent: Tuesday, March 16, 2010 2:51 PM To: caut at ptg.org Subject: Re: [CAUT] Guide rail pins 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?
