I just bought an 8" Kennametal Face Mill off of EBay.

The thing is brand new, and I got it for a song.

Downside?

I want to use it with my S1 Bridgeport, so I need an R8 Arbor for it.

It has a 60 mm bore.

Does anyone know where I can buy an R8 arbor that big?

Any help would be most appreciated.

I'm pretty sure 1-1/2" is the is the biggest face mill arbor you can find for an R8. If you want to keep it, I think you're going to have to bush it yourself. I'd only use 2 inserts in a cutter that big on a Bridgeport. Shim them so you have a short, advanced rougher and a long, reduced finisher.
