I recently reduced some silver steel down to 3 mm over about 30 mm length without tailstock support with no problem but taking it carefully with a very fine hand feed.
Hi Russell,
The statement above is worrying me, I cannot for the life of me see how you could machine a 3mm dia. x 30 long rod without support?

Quite easy if follow what I said.
I often have to make special screws from silver steel. Turn down 3/8" to cock on 3mm dia no leaway x 22 then M5 raised shoulder screwcut 3.5mm long plus head 3mm plus cut off tool 2.2mm done all in one (30.7mm) to retain accuracy. Its second nature. Then harden, temper and colour harden.
Using 8mm dia silver steel flexes.
