Thought I'd post this follow-up in its own thread as its more about DIY steel cutting than actually building the machine..
but here are literally my first few cuts in mild and cold rolled steel.. screw-ups and all.

Before building / component selection I did some research but didn't find a whole heck of a lot of specifics, so maybe
this might help someone out / give them a better sense of what to expect.

I'm using a 1.5kW ebay air cooled spindle (came with Huanyang VFD).

6mm carbide, 5mm DOC, 7500 RPM, about 10 IPM -- details in the video.

The poor thing did better than I expected but I couldn't say how long it would last doing this kind of work.. probably not long?

Tips/comments/criticisms welcomed, as always.
