What are my best and easiest options for attaching the mains (safety) ground to an aluminum chassis. Based on the suggestions of many, I've decided to order chassis for my PVA18 build, as opposed to building wood chassis. As I wait for them to arrive I've been trying to plan this build properly/safely. The chassis are aluminum, and the maker has already informed me that it does not come with a welded ground stud. I've done some reading in other forums that has honestly just scared me into making sure I do this "properly". Along with your advice, any links or suggestions for specific products (if allowed by forum rules) would be greatly appreciated. Thank you!
