Vixen Quill shafts

[Astacus]

Afternoon,

Does anyone know what the threads are on the Vixen Quill Shafts?

They look like they should be 3/4" UNC, but they dont quite match up to my 3/4" UNC threads... and 3/4 UNC taps don't fit the nuts. They don't appear to be 3/4 UNF either....

3/4 X 12.

Ah, thanks, that explains a lot.

Cheers

Not a problem.I had a hell of a time finding nuts to fit...ended up making my own.

Yeah, I have only one remaining good nut and two damaged ones. It looks like I had short castellated nuts on the drive flange and full castellated nuts on the front. Is that normal?

It looks like Namrick do 3/4 BSF castellated nuts but will have to check the TPI
