When at an auction I try to grab the odd funnel if it comes around. Have one, is galvanized, the top was made to push in a quart oil can, with a sharp can pierce inside. The spout is 10 inches long, flexible steel, great for the newer stuff where the oil fill is down low. Can dump in a full quart oil bottle, it wont run over. Have a small galvanized funnel, is made with a fine brass screen in the bottom, great for reusing oil. I also make a point to get tin or galvanized buckets, will last indefinitely, not crack like the plastic ones. When blacksmithing or welding, a hot piece can be dropped in a tin bucket, not so with a plastic one. When doing a blacksmith demo, friend cooled a piece in his bucket, then dropped it in. Was still hot enough to melt through the bottom, water running all over. I also came up with a big galvanized funnel, 15 inches across. It has two sets of fingers made at the base of the funnel part, above the spout. Made to lock into the fill hole of a farm tractor, when filling from a gas can. Just dont leave it in the tank, like a neighbors hired man did. Done for the day he added the 2 five gallon cans of diesel in the truck bed. Then it rained 2 inches that night. Not a happy boss man.
