Hi, Hermes,My drum is great but one note just doesn't "ring" right... kind of dead, though in tune. Do you have any ideas to get that note to "ring" like the rest? I'm afraid if I file or cut anything I'll change the pitch, which is right on now, but dull sounding.Many thanks!
well then, why don't you wrap your air chamber into a metal "chamber" - just use pipes that got a bigger inner diameter than the outer diameter of your plastic chamber and fill batting into the interspace to cushion the eventual outburst? (Just an idea)

Hi Frederik, the pitch of each note (in hertz), f = sqrt(stiffness/mass). The stiffness comes mainly from the thickness of each tongue (stiffness = t^3 and is therefore more critical than the mass), so if your drum has thicker wall section the pitch will go up and you will need longer and less wide tongues, to get the same pitch. You can make it artificially less stiff by filing it down and the tongue connection point (which is where it moves, so is the most critical place to influence the stiffness). Hope this helps. N

Hey Guys I live in Denmark where the standard propane tanks are either smaller or larger, and have a slightly different shape. Do you have any tips on how to adjust the shape and size of the steel-tongues to different sizes and shapes of propane tanks?The best regards
