If I was to fab up another one I would make the base a rectangle out of 2 inch square tubing so I could fab up a nice LARGE catch tray for the fluids and then use 4 casters 2 sraight & 2 pivoting with locks on all 4 to keep it from moving around when tourquing head bolts and such.
The one I built is the 3 legged version and it is heavy duty but would be much better with 4 points on the floor instead of 3.
Just my 2 pennies.
