Made a Differential Dolly

Weeell, one problem with making tools like that for helping out in the shop is they take up space when not in use. When I built my shop it was quickly apparent that it wasn't going to be big enough for everything I wanted to do and the building was nearly 1500 sq ft. After sticking in a 15" lathe, a 10x50 milling machine, 48" brake, shear and slip roll, couple of welding machines, 4 cars and a 'clean' room.....there ended up not being much space to do much work.
