I finally got around to building a workbench just for the 9 x 20 lathe. Its built from 1 1/2" x 1/4" angle iron.
It features a drawer for storage of accessories and a lower shelf.  The overall dimensions are 48" long
24" deep and a table height of 30 1/2".  All the angle iron was cut using my metal cutting bandsaw.
One sheet of 3/4" plywood was used and a couple of coats of varnish.
 

      The drawer is built from 3/4" plywood.                  The wheels are two 3lb barbell weights. I bored out
      The lathe sits on two angle iron braces                  ID of the weights and placed a 5/8" bearing.
