As already stated unfolded wood then its good tonal characteristics when at the lowest possible mass dominates the highest possible rigidity. If both factors (density and Young's modulus) at a Species optimum, which is usually also the best precondition for a high speed of sound and that makes, among other things again from good tone wood.
But since wood is a natural material, it is possible through proper handling straight in wood drying and storage take great influence on the sound quality.
Good tone wood must also be straight after drying. But when tensions were at the root (eg on Astansätzen), this now comes to light. The wood on my arm is no longer usable as a tone wood.
The process of drying and storage begins with the withdrawal of existing both in the cells and in the cell walls moisture. Once this is done, enters a "gumming" of the cell structures. In this case the cell structure is gaining stiffness. The gentler you design the dehydration, the freer away the water and the less "clogged" the cell structure and cell structures can sound enter.
The wood cells contain both in their cell compartments and their walls in water, which is passed, together with the nutrients dissolved therein to consumers. The moisture content is physically defined as the ratio between the mass of water contained in the wood sample and the mass of absolutely dry (darrgetrockneten) wood sample.
You can be a "wet" weigh Probestückchen eg, dry it so far that no more moisture in the cells is present and then weigh again. Substituting now the waxed difference before / after in the relationship with the "wet" initial mass, so you know now its moisture content (in%). The review of Trocknungsvortschritts with a balance is to follow a simple and accepted method, wood moisture for long periods.
The moisture contained in wood has to influence:
I have followed the drying process specifically. Here are some photos to it.
Notzitzen on the test piece
After more than three and a half months a balance between wood and air humidity had arisen. The moisture had reached 12%. A rather low value, which was also influenced by optimum weather. Now it's time to slow in putting away the wood inside.
Following a very interesting chart. In it can be seen that
Does the process until there out can still natural rotting as rot, fungi, etc. the beautiful tone wood destroying.
It is very important that the wood is stacked evenly. The pile must be so that to see exposed to a certain position forced the boards. On the stack, for example, I put more weights. Much Tonholzhändler stacks eg its ceilings and floors:
Full freshly cut Fichtenkanteln and standing in the background wood "run" for
Great spruce wedges!
Probably maple wedges with verwachsten ends.
