I've got this old Raleigh three-speed frame, still in decent shape, and I'm driven by the mad gods of stupid challenges to try and convert this thing to fixed. Sheldon Brown's got a blurb on doing it: according to him, the hard part is swapping out the cottered cranks and getting a spindle or bb that'll work with cotterless. Just wondering if anyone around these parts has actually succeeded in something like this, and if so, could you share your experience? I do really like the frame, and I have a vision for the build...
I also ask here because the one time I asked at an LBS, the owner of the shop simply shook his head, told me the geometry was wrong and that it couldn't be done. On questions of whether or not it can be done, I tend to defer to Mr. Brown. So please don't tell me it can't be done unless you've really tried and failed. And if that's the case, then tell me why you're sure it can't be done.
Also, any suggestions for brakes et. al. to outfit?
