Subject: [CR]Re: Worn cotter pins?

Having just serviced a Raleigh BB and crank, I would highly recommend using a cotter pin press to remove, install, or adjust the cotter pins. As tempting as it may look, hammers and cotter pins don't do well together. I destroyed one with a hammer and then consulted Barnett's manual and my LBS mechanic, both confirming that hammers are, indeed, deadly on cotter pins. Park used to make a press, but it is not shown in their current offerings. I was fortunate to be able to borrrow one from a very gracious LBS mechanic who loves the vintage machines, too. -- Greg Thies Vienna, Virginia USA
