Here is what I did guys.I bought the required material from a company that specializes in metals.A.S.A Alloys. They sell
stainless steel,nickel,aluminum.They deal with big orders though.I used 1/2" thick aluminum angle line sized @ 4"x6".
I cut four lenghts @ 30,1/4" long.I braced each set together with 2"x4" aluminum tubing.I drilled and tapped two 1/2" holes under each angle's 4" side.Thats where the 1/2"threaded feet are going.The final product looks massive and very impressive.So I made two amp stands with overall size 20,1/2"wide by 30,1/4" deep.Height including the stainless feet is 7,1/2".
Top platforms will be made out of maple and will be resting on the aluminum stands on brass cones.All my connections are with stainless steel screws to keep it non-magnetic and the tubing could be filled with sand or lead.Allthough that would make them very-very heavy.They are HEAVY now even though empty.
