Would anyone have a cotter press that I can buy or borrow for a few days? I've got a '74 Sports with a particularly ornery cotter on the chainring side. I was able to tap out the other side with firm whacking with a slide hammer, but the sliding weight doesn't clear the chainring. So I used a rod with the crank supported on the end of a 2x4, then went over to a large plumbing vise and still no success. The cotter is peening over and beginning to bend. I now have the bearings out of the non-fixed side so the crank is now floppy, argh. I'm in Wisconsin north of Milwaukee.
