This is a pretty crazy thread. I mean, when I was a child back in the late '50s, I decided I wanted a Bendix Automatic rear hub in my Roadmaster. Part of the job was converting to 1/2" pitch from 1" pitch, so I had to put a chain and front chain ring on it. When I saw the picture of that big cone with the two flats, it all came back. My dad had tools, including really big adjustable wrenches. I did that kind of stuff myself. Its been many years, but I think I had the bike shop build a new wheel for the Bendix. I can't get my head around anybody having this much trouble taking the chain ring off an 'ashtabula' crank.
