Cross threaded Cassette Fix??

There's a first time for everything, and for Halloween (perhaps I was
distracted by passing out candy at the same time I was working) I cross
threaded a cassette lock-ring. Other than tossing out the cassette body
(Zipp NOT TOO cheap I imagine). Has anyone just removed, and tapped threads
back in (what diameter/pitch?, I assume it's a standard, but my cassette
body is Campagnolo)?

The damage was not too major. About the first 4 threads were chewed up.
I'm sooo ****ed, I've build wheels, bikes . . .etc. .And never screwed up
like this. It was weird, there was no resistance to indicate I was not
parallel to the cassette body.

Unless you have totally ripped the threads off, you could probably line it
up properly and screw it back on again.

Yes, Lewis. That's what happened on my 6th or 7th try. I applied pressure
in just the right way and it's on perfectly. Initially, the way it went in,
it was at like a 10 degree angle, and would no longer engage threads, so it
only chewed the first 3 to 4 on one half of the cassettes threaded portion.
Whew. .! I've had enough excitement for tonight.. .

Dirk

Glad to know you've got it fixed, Dirk.

next time, try one of these:

makes life a lot easier because having the spike inseted into the axle
effectively alligns everything for you.

The tool we use now for Shimano spline cassette lockrings
has a 50mm long 5mnm shaft in the center. It's made by Lifu
and sold under several house brands. Cheap, too. It makes a
difference when either the lockring or the body ( or both!)
are aluminum.

We don't have a Campagnolo pattern tool like it, however.

To your immediate problem, I'd get a steel lockring of the
proper thread and cut a slit or two in it, then use that as
a tap for your marfed body threads. You'll only be removing
material, that is to say, you won't recover any lost thread.
But in aluminum the usual failure is a galling or smearing
of the material and that would at least clear the extraneous
swarf out of your thread. Good luck!
