Brad,
Most of those machines are 3-phase. So I have a rotary phase converter making 240 single phase into 240 3-phase. Those 2-gang outlets have a separate 3-phase, 20 amp, 240 volt recepticle and a 120 Volt 20 amp recepticle.
No, I mean what are you planning to MAKE with all those machines???
Do you wake up in the morning after dreaming of something metal and think: "Today, I'm going to build a 6-piece, gun-drilled, 4130 chro-moly Framistotz valve... with a hydraulic hinge in the middle!"?
