I have recently purchased a Supermax 19-38 drum sander. The drum sander was on back order, so in the meantime, I decided to build a rolling cabinet for it. The sander does come with a metal base, but it has no storage and I have heard it can be a little rickety once casters are added. One other detail is that I have also purchased the folding infeed/outfeed tables, so they need to be accounted for in the design.
