This bass came to my workshop because the neck had come loose. After I removed it completely, it became clear that there was so much air in the glue joint that it couldn’t hold…
The neck joint on this bass is designed as a hidden dovetail joint, but it is so imprecise and has so much play that the glue joint to the back plate alone actually bore the entire load. We therefore decided to chenge the neck joint to a screwed connection. The reason for converting to a detachable neck was not easier travelling, but the screw promises to be the most durable connection here (a completely new and cleanly inserted neck was ruled out for cost reasons).
During the renovation, it became apparent that someone had already attempted to solve the problem of the loose neck with a screw: someone had screwed it in from above through the neck foot, but it was crooked from every angle. It eventually broke, and during another repair attempt, the screw hole was doweled again. However, the broken-off remainder of the screw is still stuck in the neck block.
After patching the dovetail joint, the neck is now securely held in place by an M8 screw—the counter thread was inserted into the neck block from the inside (bottom).
