Hi Robert. Not sure if this is the place for this comment, but you mentioned on your You-Tube channel some time ago that you were working on making a waste oil boiler/heater for your shop. I'd be very interested in your ideas and/or progress. I have a wood boiler currently heating the house, domestic hot water as well as the "solar room" (basically an insulated shed holding up my solar panels and housing the battery packs). Since it's heating the domestic hot water, I keep it going year round. Would be awesome if a waste oil burner would keep this thing going.

This is probably super basic for most here, to the point of "put diesel fuel in your diesel fuel tank, but I'm posting this as a "just in case." McMaster Carr is a resource you HAVE to have on your bookmarks/favorites of your browser (or the app on your phone) From every piece to make Rob’s DIY AFC Live, to 3/8" 6061 aluminum plate for your trans skid plate, to that m1.59 torx button-head screw, they have damned near everything you need in a fab or mechanic's shop. https://www.mcmaster.com/
