This is a shovel I'm building for a friend, the tank was his idea, I'm mearly working with what he gave me, although it does grow on ya and I do dig it. It will be gloss black when done. The radiator cap is from an old ford. I had a guy machine out a bung for it. The brass petcock is a Hank Young piece. The tank is an old Ducati. Going with different trees too....a spool front rim with a perimeter brake and lots of other things...not real close to being done but it should be pretty cool.
