Mobilitiy, machine skates

Hello,

I would like to know about machine skates. I am seriously close to
asking my school if I can buy their Bridgeport. It's going to be a joke
moving it out of the classroom where it's sat for 40 odd year but at some
point I should be able to attach some machine skates. I plan to set it down
in my mum's garage and she really doesn't want it to be stuck in one place.
So I was wondering how easy is it to move something like a Bridgeport once
it's on skates? Could one or two people push one? I know ideally it
shouldn't really move but life is, as always, far from ideal in this case.

Thanks
John
