    I have been fortunate enough to obtain a late 50's Rollfast Middleweight cruiser. Most of the parts
    are intact and in excellent shape, except for the bent one piece crankarm. The original crankarm on
    those bikes seems to be a really weak design compared the the Schwinn equivalent. I'd like to use
    the original chainring because it is in fantastic shape, but there seems to be a problem with the
    drive side cone on the crankarm. There appears to be no flat spots to allow it to be wrenched off to
    free the chainring. Is there a trick to removing these, or am I going to have to machine some flat
    spots in that cone? I did a Google search on it from many different angles and was unable to come up
    with anything. Thanks.
