Found the one I had seen before,

I personally would mount a pair of 6 inch or so wheels at each end of based
spaced maybe 12 inches or so apart so the drum could rest on them. Most
hardware's have fairly inexpensive wheel in various sizes. RM~

I'd agree w/ you on that...this doesn't look like it would be very
sturdy at all from the description. A 1/2" rod for a 45/55 gal drum of
damp material isn't much and the frame isn't all that stout, either.
