update:

i glued the cog and lockring to the hub with JB Weld. I've taken it for a couple short rides and it appears to work fine. I've grunted up a few hills, skidded, all that.

it is SO good to be uncoasting.

Before I glued it, I threaded on the cog and lockring to check whether the cog was wide enough. The lockring did not appear to bottom out. But I could be wrong. Either way. All hubs from here on out get Phil or EAI cogs.

Thanks all for your kind wisdom.
