Best way to machine ball screws?

[gavztheouch]

Can you redesign and go down to 10mm ?

Yes I can, bearings are bought already but hopefully it will not be a problem to swap if I pay the postage.

John S would it not be a good idea to try your steel plug trick?

How does everyone indicate there ball screws in the chuck? I know of a method by 5bears.com

And here is a great tutorial using a Derlin rod machined to slip onto the ball screw to give you a surface to indicate off. Is there any other way of doing this? http://www.5bears.com/cnc16.htm

If you can go for 10mm I'd definitely do that... it will be much easier.
