Stripped hub - feck!

I know this an old post, but its great to have website where people have been through it all before......

it was all going according to plan, got a 17t miche cog from condor and a chainwhip/lock ring tool, swapped the cog put on the lockring. rode it round a bit then tried to tighten the lock ring a little more just to be safe in case the cog had tightened more from pedaling... MISTAKE! the lock ring lost resistance and now just keeps turning. so i've stripped the thread right? unrideable? gonna need to buy new hub, so any suggestions?

I've done the same thing as this to my fixed gear - changed to a different cog, and it hasn't been the same since. The lock ring thread is stripped. Tried tightening (many times), and have also tried with loctite, but everytime its tightened, i go riding, do a few skids, and the cog starts unwinding. think its totally "screwed"...

Anyway - anyone think of any options other than replacing the hub (complete rebuilld) or a complete new wheel?

how about welding it on?
