I've done it, but it was an act of my own stupidity. Not the hubs fault. Got a little crazy with the loctite and couldnt get the lockring off. Stuck it in a vise and... Viola! No more lockring threads. And if that isn't bad enough... I did it to both sides. (wasn't there a dumb things we've done thread somewhere) Either way i still ride the hub. One side the cog is jb welded on (the best in skid confidence) and the threads are still there to put on another cog when this one wears out. Then and only then will i get another hub. It will probably be a surly too.
