Well no luck online or locally finding a 20mm x 1.0mm nut.
Closest was 20 x 1.5.
I guess I will have to clean up the original and devise a method to tighten it.
Thread locker and a brass punch, or perhaps try to cut a large socket to fit.

OK It ain't pretty.
In fact - kinda ugly.
But it has "functional beauty". I think it worked.
Basically a scrap of steel pipe, Dremel, files, and some "retirement" hours.
I tossed the mangled tab washer and used some thread locker.
Fingers crossed.

Great job! It's always satisfying to make a tool that does the job in a controlled way rather than just whacking the part with a hammer and drift. I have a number of those crank nuts which have been butchered in the past and I am preparing to make a threaded fixture (hence the M20 x 1.0 die) for my lathe.

I made a similar tool by grinding a 1/2 drive socket. No prettier than yours but easier to get a torque wrench on.....

This came my way with a genuine Honda workshop tool kit.....

This one is marked for the S90 but fits the CB72 crank nut perfectly.
