Stave drums. These shells are known all over the world for their unbeatable sound. No manufacturer will ever achieve this quality with plywood drums and that’s no secret. The combination of clarity, sound and resonance that solid wood instruments produce is and remains unique. No other construction sounds nearly as fantastic.
Drums are basically something very simple and sound due to numerous factors in their own way. The freer the shell can swing, the more natural it will sound. Low shell tensions, few impurities, good hardware that does not restrict and natural shell materials.
The good tone starts with the choice of wood and solid wood is the argument par excellence when it comes to good instruments. What sounds more natural than nature itself? Wood that is always well seasoned and suitable for instrument making is used. The planks and boards are hand selected and used accordingly. Mostly built with maple (from own production), Afzelia Africana, walnut, cherry, wenge, mahogany, oak, elm and padouk.
Far more types of wood can be processed and are available for almost every wish.
797:1 -> You should remember this number
Specific angles are milled onto the selected boards and these boards are then arranged in a circle and glued. The amount of adhesive is negligibly low. One can imagine that adhesive does not really make a good and natural tone. Comparing a 6ply drum with an 8mm stack drum, the adhesive ratio is estimated to be 797:1. With more layers correspondingly larger!
Thin shells manufactured with precision
The shells are manufactured with the assistance of CNC technology, which enables me to guarantee a very high standard of shell quality. This means that the manufacturing tolerances are very small and this is reflected in excellent tunability and a clean tone. Subsequent and continuous fine-tuning by hand draws the last pinch of potential from these drums. The stave drums are made as thin as possible so that the range of the drum is large. With the right choice of wood, a BD shell has only 8mm and guarantees a very full low-end.
The grain of stave drums is normally perpendicular to the bearing edge and this has its advantages. The bearing edge of the drum is very stable (anisotropy of wood) and remains exactly as it should be. Especially with deep shells there are further advantages. On the one hand, the flexure on the radial side of the shell is subject to low rigidity (stiffness) and on the other hand the body-borne sound spreads much more easily and thus more quickly along the wood’s fibres. So in the direction of the resonance side. This results in maximum resonance and a deeper keynote.
Stave drums are produced almost tension-free and beyond that they are also turned in a cnc machine. Drums have internal stress conditions due to production which are reduced over time as the shell deforms. According to the motto “The weaker one gives in”. The tension conditions vary depending on the type of production. With stave drums these tensions are not present until hardly. Just so you know.
Drums are also deformed if they are tuned improperly -> very different tension conditions of the skin cause the shell to be deformed. So clean tuning is preferable!
