Ball turning adapter

[Jesse Hancock 1Participant @jessehancock1]

I'm contemplating buying a ball turning adapter however I need information as to how small it can handle.

5mm 10mm 15mm??? It's nice to think that turning handles and knobs is now childs play but I haven't found any info on how small a ball or inside curve it will turn.

Has anyone on here bought one and experimented with it to find out it's full potential?

Meanwhile I'll try Googling the ether and see what turns up. (Oh the irony of it.)

bought the repton one from chronos only used it to make some 1/2" radius dies so far, but good bit of kit.

not sure how small it goes though.

My guess is that outside diameters isn't an issue down to almost 0. Internal is a different matter and will mostly depend on the tool you use not fouling the work.
