Physical crack after the instrument got kicked over.
Physical cracks- Accidents
These are typically seen on tenons and sockets. They are caused by force and are not covered by warranty.
The most common scenario is, that the instrument fell or was kicked over.
If the receiver, thats the top of the lower-joint or any of the barrel ends, is cracked, too much force was used to put the parts together or the tenon was swollen.
Attention:These are the only cracked which sometimes can justify pinning!
In most cases there are better ways and it should be the last option to be considered.
Some of them look really dramatic, but almost all of them can be repaired very nicely.
Thats what happens when you try to pull a stuck swab through the instrument with force the wrong way.
