So after getting a Thomas banjo yesterday and messing with two broken tuners enough to try them out, I put them on the neck and gave things a go.
Quickly realized that I had missed the fingerboard separating from the neck. Also see some cracks near the peghead on the neck.
I do have glue syringes and have been down this road before with another cracked neck.
I am inclined to inject Titebond into the gaps by slightly spreading them and clamping it together. It is a thin neck. I think it is walnut. The finish is rather thick.

Neck and peghead appear to be connected but are showing some cracks.

Open to suggestions. Will be right back with popcorn.
Thanks,
Tom

Good luck. Finicky work required.

It appears that it's been broken before and poorly repaired. There's some warpage and misalignment of parts.

This is not a job for a person with limited experience.

It appears to have some cracks but I am pretty certain it is not a prior repair.
These are contained cracks.

Had a similar issue several years ago when the USPS damaged a vintage padauk neck.
Got cyanoacrylate into the cracks and used titebond on the FB separation.
This go round will be cyanoacrylate liquid in the cracks and gel between the FB and neck.

That neck is toast. I hope that you got it free.

Although I disagree with your thinking that this was not previously repaired, and also disagree with your choice of cyanoacrylate gel, I do hope that you meet with success.

Personally, I think Bart is right.

Well, if it's not toast already, and you try CA and it doesn't hold, it will be toast for sure.
I heartily suggest you go back to plan A and use Titebond Original. That way, if it doesn't hold, you'll at least be able to get the fingerboard off in one piece [more or less] so you can salvage it for use on a new neck.

Cyanoacrylate seems to have worked fine. I strung up the banjo tonight and played with it.
The original nut was broken so I cobbled a new one together. It needs more trimming but it sounds pretty decent. Some slight intonation on the third string. I have a basic bridge on it.

So now, I will tweak the nut and then tear it apart and clean up the glue and finish.
I used liquid CA on anything that appeared to be cracked. I suspect some were just cracks in the finish. I would rather refinish than deal with an active crack.

This banjo has the number 5 on it in several places. I would assume this is his fifth one.
Does anyone know how many banjos Don Thomas made?

Thank you for all the comments.
