I made a rolling base, just a board with 4 casters. This is a big project, BIG I say!! JK. I have found this to be a handy tool around the brewery. I use 1/2bbls sankes as fermenters and serving kegs and it makes them so easy to move. When I clean out the MLT, AKA 55 lbs of wet grain, I roll it out to the trash can; my back thanks me. If you get a chance find some big locking casters and make on of these up. You want locking casters, so you're not chasing it around holding a keg. It is just a handy tool to have around IMHO.
