maybe easy to fab if you have a 5 ton press in your backyard. the circular
track in the bottom plate is embossed in the metal..
if you have a radial die cutter / cutoff wheel (ie, a dremel on steroids) you
can cut the bottom plates off at the welds.  not hard to do, just wear eye
protection and buy a few extra carbon cutoff wheels.  i went thru 2 to vut a
pair of swival bases off.
FYI Sears has the electric radial die cutter/ grinder. these are super high
rpm and  they are about $80 and theyre an awesome tool. i use it to cut
everything from metal to plastic because it makes a clean cut.
