Don't Try This at Home!
I come before you humbled in this posting. I thought that I had a great idea to advance the design of the Hank Drum by accomplishing two goals:
1. Speed the cutting time for new drums.
2. Reduce the pain in @$$ cutting of the small curves in the tongues, and save blades lost when they break cutting the small curves.
So I sat down with Visio and designed a new tongue design which (on paper) seemed like a great idea. I borrowed the concept from woooden tongue drums which I have played in the past. In the picture to the left you can see the basic design, a large hole cut from the center and then the tongue cut back from there...
From the picture on the right, you see the completed drum. BUT it doesn't sound great at all. After the initial removal of the hole in the center (5" in diameter) the drum sounded like a Tibetan Bowl!
Even after I cut the first tongue (the lowest D note) the drum sounded great. The low D note rang for a long time. But as soon as I cut the second tongue, the whole drum design went south... the addition of a second tongue confounded the first note and neither note sounds good. To complete the experiment I finished cutting the whole thing out. I did achieve one goal - the total cutting time was less than an hour!
My advice: don't waste $30 in this design direction. But I am going to salvage the tank by cutting out the tongues and getting back to that awesome sounding large Tibetan Bowl!Check out the Hank Drum Collective: http://hankdrum.collectivex.com
