I have a piece of 2.4 mm silver steel, I need to turn two bands in it, 22mm wide by 1mm deep with a 1mm gap between each band. Any suggestions on how to do this on the super 7 without it bending and breaking ?? I don't have a steady and to be honest don't see how it would help.

There was a tool by Arrand Engineering that would help you do this.
This tool is mounted on the tool post. It had a brass or phosphor bronze bush drilled to the diameter of the work.
The turning tool is clamped alongside this bush. The work passes through the bush first as you turn the work the bush it almost rubbing the turning tool so that you get no deflection of the work.
Anyone know Arrand Engineering website?
You could easily make you own similar tool once you saw how it was made.

Couldn't find website, google came up with this.
Not sure if it's correct.

You can make up a travelling steady to suit by using some sheet brass attached to the cross slide, with a
2.4mm hole drilled in it from the headstock.
If you have a collet chuck or an accurate enough normal chuck just do a few mm at a time and then move the bar further out of the chuck and do a few more mm.

I'm not at all sure why women like men. We're argumentative, childish, unsociable and extremely unappealing naked. I'm quite grateful they do though.
