build yourself some flip top tool carts. They're good space savers! The tool less used can stay on the bottom side.
I am currently working with an electrician. He was speaking electrical which I don't understand...said something about running a 60amp something or other from the main panel. He said that would have enough to a couple of 220's plus all the 110 I needIf you do not have a 200 amp service, I would recommend getting one. Once it is installed, you can then install a second 100 amp service. Then anything powerwise can be fed by the second panel. This is way easier than trying to juggle an existing power system, especially if it is older.
