>And Anygood for what.?

Ah, sorry Jazz, was being a bit vague there - just ballpark any good for cutting alu plate. I'm not too bothered about crazy feed-rates and am happy with smaller step-overs. Reassuring to hear that it's a good starting point!

One more question, the pillow blocks which house the bearings that ride on the rails - they have grub-screws that you can tighten to get a snug fit between the bearings and the rails - how tight do you go with these? Just a nip front and side?
