As I wrote about in my New Spindle Design post, I have designed what I think is a better Spindle and Platen for my Omni faceting machine. And it’s just arrived today!
I’ll write more later, but here are a couple of pics to compare with my original (modified) Omni Spindle and Platen.
I haven’t tested the vertical runout myself yet, but from the guy who machined it:
o.d runout : .0002 face runout: .0004
Compare that to my 0.007″ current runout! The new one has 17.5x less hop than the original!
