Stupid unfixed fixie v2: The Reckoning (Londonfixie?) Fix it, repair it, how do I do it, what's the best part to use, and now: how do I get there?

[mechagodzilla]

Recap:
I have a shitty fixie conversion with an IRO fixed/fixed rear wheel. I stripped one side of the hub by using a bad lockring, then bought a new cog / lockring for the other side. It's been solid for about a month, but it slipped again a couple days ago. So I took it apart, cleaned it and put it back together with some Loctite in the threads. That bitch is basically welded on now.

If it slips again, I want to ditch the hub and switch it over to a bolt-on cog from . Anyone actually gone this route? I'm wondering how to go about it - buy a disc front wheel somewhere? Get a disc hub, convert it and rebuild my current wheel? Buy one of their hubs? I've never built a wheel before...

Thoughts?

I'm building up a rear fixed gear wheel using a Shimano M756 front disc hub and a and it's going to be awesome. One other thing that's cool about the Shimano hub is that you get cup-and-cone bearings, rather than cartridge bearings. As soon as it's done I'll bring it on a ride so you can check it out.

So I got my wheel built. I used a TomiCOG instead of one from londonfixiebike.

It's been working great so far.
