The tools you'd need for the job?
-Some 1/8" steel or aluminum (steel holds up better but might rust if you don't powdercoat or paint it thoroughly)
-plasma cutter/nibbler/angle grinder with cutting wheel or some other cutting tool to make pieces of metal the right size
-cardboard or posterboard and scissors to make paper brackets before wasting a bunch of time with steel or aluminum
-file and sandpaper to clean up edges and smooth out the pieces
-dzeus clips and time to get it all sorted unless you are smooth enough to TIG weld the stainless nylock nuts to the brackets for the hex screws.
