We need more people like your Dad!My dad saved them up, cut them in half length ways, welded on legs made from 3/4" galvinized pipe we had ripped out, and sold them once a year at a local farm auction. We averaged about $25 a piece. So that's $50 per WH minus a couple dollars worth of gas and welding rod. This was 1980's dollars.
Actually, as time went on, I had to do the cutting and welding. But he kept the money! LOL
That's outright theft, I'd call the police if I had their plate number and vehicle make/model. I've had to yell at guys and threaten to call the cops when they walk onto a job and start helping themselves to the scrap. Never actually had to since they didn't leave with anything.Every now and then the scrappers will drive by and see one sitting out by the truck and they snatch it up. Usually before I can rob the brass off it. Those little bastards are quick.
Exactly what I do .We figure the cost in the total, so it gets hauled off unless told not to, we dump them off at our supply house fenced in yard, they in turn take care of the disposal, don't cost us to drop them there.
