A [Hank Drum], as explained here, is a steel drum-type instrument constructed out of a propane tank. The name comes from the [Hang] or [Hang Drum] which is considerably much more costly than that $40 or so an empty propane storage tank costs. Of course, you’ll have to do some work to get it to play lovely music, which can be seen in a time-lapse building video after the break.
The details of exactly how this instrument was made can be discovered here, including exactly how to lay whatever out as well as cut out eight fairly neat “tongues” for creating different tones. I utilized a Dremel tool, however this can likewise be done utilizing saber saw for a rounded top. This technique is explained right here with a template, however the results may not be as neat.
If you want to try this yourself, make sure to utilize an empty, unused propane tank. This is incredibly important. For one more completely different homemade instrument, why not inspect out the [Whamola] that we made a year or so ago?
