Word of advice if you are wanting to build your own... make sure you build it wide enough that the drums fit in it. The first time I assembled it, I didn't account for the stiffner rings on the drums. I took the diameter measurement at the top of the drum and added an inch. When I went to put the drums on it, they wouldn't fit
So I had to tear it apart and add an inch to the center cross tubings so they would fit.
