In early 2013 I made something called a “Hank Drum,” a sort cheap derivative of the Hang. I’m happy to note that reader Gary Van Arkel decided to not only build one of these drums based on my plans, but tuned it to a D Minor Pentatonic Scale, and shared the dimensions via a comment. After a short email exchange, he even provided me with pictures, including the sticks he uses, made with 1 3/8″ rubber balls on 5/16″ dowels. So wtithout further ado, here are the dimensions:
D Minor Pentatonic Scale Tongue dimensions:
- 1 D3 147 2″ 10cm
- 2 F3 175 2″ 9cm
- 3 G3 196 2″ 8.5cm
- 4 A3 220 2″ 8cm
- 5 C4 262 1.5″ 7.5cm
- 6 D4 294 1.5″ 7cm
- 7 F4 349 1.5″ 6.5cm
- 8 A4 440 1.5″ 5.5cm
More Build Details:
- Cylinder used was Australian 4.5Kg gas cylinder.
- Reduced inner circle circumference to 3.5″ and outer circle circumference to 5.5.″
- Used Masking tape to mark the larger 2″ tongues, and a 1.5″ width business card to mark the smaller tongues.
- Started cuts to 1/8″ holes with .89mm cutting disc which fitted my Ryobi angle grinder.
- Extended cuts with jigsaw and tuned with hand hacksaw blade.
- Tuned to my Tablet from an app named Best Tuner.
Reducing the circumferences seems like one of the most important notes here, as this may help spacing when being played. It should also allow for deeper notes without cutting the sides too much. Just remember, as in the first Hank Drum post, be sure use an empty and never-filled tank!
