Some may have noted in my other threads, that I have an old Schwinn Varsity that I'm trying to turn into a budget commuter. One option that I'm looking at is converting it to a single speed.

I found some information on how you can convert a Shimano (and some other) freewheels into single speeds using spacers to replace the unused cogs. Anyone ever done this or see any reason it shouldn't work? I like the idea of having a selection of cogs and being able to fine tune the chain line by moving spacers.
