Lathe restoration SN20

[NortonDommi]

Serious stuff, the TOS machines I've seen have been virtually bombproof. One interesting thing I saw on one about ten years ago was that both longitudinal and cross feed could be set at different feeds and both engaged alone or together. I've never seen or heard of anything like this before or after. Owner said it used to be used in making tank parts. I don't know whether this was a special or an option but I thought it was a great idea.

I used to own a gromematic Dutch built lathe that could run both the cross and the longitudinal feeds Simultaneously by engaging both the lead screw and the feed shaft but not independently adjustable.
