Lockring threading is screwed... advice please

Could I skidd with that setup ?

yeah. I never got this either. One time I was stripping the cylinders off a marine diesel engine. They were held in place by these big bits of metal studding. One one stuck so to get it off we threaded on two nuts and applied serious amounts of torque to the lower one, including whacking it with a hammer (thus applying 'shock' forces, presumably similar to skidding). The upper one didnt move at all. And as I understood it, this technique is used reliably in other situations as well (as suggested above).

Now, Im not advocating it, and a proper fixed lockring will always be better. But I do wonder why counterthreading like this doesnt hold up with bikes.

Flipside, if the lockring is not secure, and the loctite is doing the work, then why use a lockring at all?[/quote]

yeah , thats where my thought comes from. I worked on a shipyard in Hamburg..
on a ship engines mainly. one comes across this all the time. And I think a engine shakes a lot more
than a skid. I will go an give it a try and of course I run a brake.
Personally I do not understand why not all cogs simply get screwed on the hub with six bolts.
Thats the strongest releasable connection there is in mechanics...

I probably will only use it till Kiwi gets the open pros back in stock :)
