These bloody Bridgeports are a tad on the heavy side...
I moved mine this evening with the aid of my engine hoist. And a crowbar.
I got it "flying", but I could *not* move the hoist by Nigel-power. I had to crowbar it into its new position. I found that a constant stream of obscenities helped enormously.
I am now trying hard to ignore the undeniable fact that it wobbles a gnat's wossname in its new home. I'll see how it goes, I may have to figure out some sort of "inject concrete under the bugger" scheme if it turns out to be a real issue. Alternatively I could remove the flooring (chipboard over 1" battens) where it stands, and let it sit directly on the concrete base.
