I built this Hank Drum a week or so ago with the help of my illustrious friend Mr. Travis Kimmel. Travis is the owner of a well stocked junk-yard and with my purchase of an empty propane tank and some metal-cutting jigsaw blades + pneumatic angle grinder wheels, we build this drum in a matter of hours, in time for that night’s bonfire.
The propane tank is 20 lbs., bigger than I would have preferred, and the video here shows it prior to tuning (a task I have yet to undertake). This is the tutorial I used, with many many thanks to Mr. Dennis Havlina, the originator of the Hank Drum.
materials used: jigsaw, angle-grinder, pipe-wrench, vice, sharpie.
