I've nearly finished the rearrangement. I swapped the little mill and drill press around then moved all the tables etc. I did it yesterday afternoon, it was 30 degrees plus in there, was the nearly the end of me! The insulation and the fan does help though.
I'd like more space but I reckon I'd just fill it with more stuff (I probably don't need). I'm actually going to have to sell some of things I don't really use to clear up the clutter.
I've always been envious of the American basements but I wouldn't like to move a lathe or mill down a flight of stairs.
