Lucky Lab, I love ya, but you really need to deal with your crap-ass wobbly tables. We are not talking about the little annoying wobble that one can eventually get past, no - some of your tables move about 6" up and down. Add in the uneven floors, and there really is no point in the table at all. So listen up: rent the big drum sander and level the fuck out of those floors. Then get your screwdriver and get to work on the tables. Hell, you could even get some new ones - some of those would not make St. Vincent's cut. Seriously, people, have some pride.
