L&P conical metal tenons

Tapered metal tenons
At the factory, many tenons are slightly conical, so that the diameter at the end of the tenon is about 0.2 mm larger than at the beginning. This has the advantage that the individual parts of the instrument can be pushed together without resistance. If the diameters are matched very precisely, this results in a very good mechanical and acoustic connection, since then the connected parts always resonate together like a body.

Disadvantages
1. If the instrument has a pure wood tenon, the moisture can cause the different body parts to expand or contract differently. Then it becomes problematic to collect the instrument parts properly, they can get caught in each other, possibly not being able to be pushed together completely and the instrument is too long.
2. Disassembling can also cause problems.
3. The conical tenon has only one point at which the instrument is securely assembled. It is almost impossible to pull out the different parts, which could sometimes be advantageous in terms of intonation, because it would quickly create a leak.

L&P tapered metal tenon
To fix the moisture problem, we offer tapered metal tenons and receivers. A change in the diameter is excluded here. However, there is also no possibility of partial undressing there. If this is desired, the cylindrical metal pin is the better solution. LP Cylindrical metal tenon

Conclusion
Perhaps the best combination is a cylindrical metal tenon between the upper and lower joints, which enables pulling out and a conical metal tenon to the barrel. This allows freely choosing between different barrels and increases the response and focus of the sound.
