I used a 8 foot grounding rod and ran separate ground wires for the equipment as per the instructions for my powder coating machine. I also ran all the grounds for the switches,plugs,lights and exhaust fan back to the ground rod so 100% of my setup is grounded to a 8 foot rod separate from my shop electrical ground.
From all I've read, it helps to seperate the two types of current that want to go to the earth;
60 cycle ac and
static used in the PC process. I like to keep them seperate but in your case, putting them on the same ground rod takes care of that.
In the PC process there have been may arguements presented, so this is just my $.02 worth.
Keep the household (shop) power grounded to the house/shop panel and run the charge from the piece being coated straight to it's own ground.
I also have the cutter grounded to the 'house' and the work grounded to the earth.
