Thanks for the referrals, guys! Yes, to me, this neck certainly looks repairable. I've put necks back together that were in worse shape than that.
But, I am booked solid with work on my own Scroll Basses, and I can't take this job on. Likewise, Jeremy (Mr. Freekmagnet) is all booked up and not really interested in Scary Repairs jobs.
Scary repairs like this aren't really that difficult (or expensive). But most Luthiers and repair people don't do them because they are afraid of the risk of it not going well.
Keep looking. I'll be glad to offer advise.
