Best way to machine ball screws?

[cncezee]

You are allmissing the thread,, ball screws are case hardend,which means the centre is soft.

simplydrillout the centre and insert a steel pin of your desired size, lock it in with anarobic glue.

Works ever time for me,and i have never had one come loose yet

ummmm but thats exactly what JohnS was doing...

You drill and ream the hole in the end of the screw

His approach was more about how he does it so the extension stays put...
