Brian.

I was thinking about the off the shelve axle he brought to me with the same dimension but shorter. The request then was to increase the length of the 3mm dia section at both ends. The M2.5 holes were in the axle when he bought it. I used a tiny boring tool bought thru an Irish friend from UK to do the turning. Seemed to work ok. But I did turn down very little amount at a time with the tiny boring tool that has very sharp edge.

I think your suggestion of putting in a stud or screw while turning is a great idea; lesser chance of a screw up.

I'll be off to Israel for 10 days from Monday. Will order some 4mm SS rods when I get back.
