Better to put an advert in the ‘wanted’ section. It won’t disappear from view as quickly!
But why not just make one? Is it special?
I’m making a 1/2” arbor at the moment (just needs threading). I made a 22mm arbor for my Centec and 16mm for my rotary table. Soon need an 18mm one as well.
I start with a soft MT blank, fit an oversized bar in it and machine to size. Shrink fitting worked for the horizontal arbor. I might pin it sometime, but it doesn’t get really heavy use.
