Uniglide Single Speed conversion?
Hi all, I've the misfortune of getting my hands on a Shimano 600 Uniglide hub laced to an Ambrosio wheel. It's not a bad wheel, instead of throwing it away, I was thinking of converting it to a single speed by using the last cog that is the lock ring, a 13 teeth cog, with a small chainring, 39 teeth.
Can I run the lock ring cog, without any spacers? If I use it that way, would it just chase new threads as I pedal. I am not sure how hard the metal is on the cassette is. Any thoughts would be great.

Uh I would NOT do that. If you just the thread on small cog how will you get it off if you ever need to?
What I do is get a bunch of spacers and add them to the cassette body and use one of the slip on cogs. Using the spacers lets you set up a pretty straight chainline and can be fine tuned if needed by putting spacers on either side of the cog. To hold everything in place I use the lockring from a bottom bracket.
Cheers

That makes sense, but getting those big enough spacers is quite annoying and for what they are, the spacers are relatively expensive.

No need to wonder, I've done it several times, and plumbers use them to loosen much higher torques. I'm not suggesting that using the threaded cog makes sense, I like your idea better, and have done it that way myself as I have a bunch of uniglide stuff
