Looking At A Bigger Mill

[Mayhem]

I'd listen to the spindle bearings whilst running it through its speeds in both lo and hi range. Test the quill feed works. With the table in the centre, grab one of the ends and see if it moves (i.e. does it twist on the saddle). I'd check that all the levers and handles rotate smoothly. Look for signs of abuse.

Basically, if it doesn't look like my Kondia did when I first got it you should be OK
