Homemade Coolant Recovery Tank

Thanks! I don't have a tig setup to weld aluminum, so scrap steel was my medium. I could probably get 3" diameter but would have to cut the height down to clearance the horns, it is pretty tight down there. Cost was free. I do have a propane bottle that would work but the darn thing refuses to go empty, seems like I have been using it for years lol.
