There are at least two instruments in the shop that need necks reattached. I was shown how to do this when the entire neck is detached, but two cellos are broken at the joint and the method shown me might not work so well. Google to the rescue! I found photos of commercially available models, selling for multiple tens of dollars, and decided I could make my own.

I used some of the mahogany at my disposal, some 3/8 in. threaded rod, and some sheet cork I was given a few years ago. Failng that, I would have used some leather I have around the shop. I had to purchase 4 wing nuts for the rod, but I had plenty of nuts for the opposite ends. Some clear tubing was also purchased to slip on the rod to protect the instrument from the saw-like edges of the thread.

Mandatory Glue-up photo. I attached a small disk to the ‘bottom’ pieces to better focus the pressure of the clamp on the ‘button’ of the neck. This is also a feature of the plain, faceless commercial models.

Cork shown on the concave upper jaw and on the disk of the bottom jaw.

Violin clamp shown as it woukld be used, though it would be best to remove the strings before making any repair.

Perhaps as much as I enjoy making custom made tools for my new trade. Starting in May, I should have time to start some woodworking again.

More useful tools, Dave. Good thinking on the plastic tubing protectors!

Thanks, Candy. Unfortunately I can;t take credit for the tubing. I saw it on a video.
