I don't have any pics of the olive barrel, which was re-purposed as a cat perch long ago, but I do have these.
Sorry about the thumbnails; the full image just took up too much real estate. The neck has a scroll, not a typical mandobass headstock, and with the mensure set at 42" I get an octave and a major fourth (C above the octave G) clear of the body. (The more notes I can get before having to go into thumb position, the happier I am.)
A lot of serendipity came into play here. Having concluded that the olive barrel body was just a deal-breaker, I had to ask myself "Where am I gonna find just a mando-bass body?" And about that time a fellow up in Oregon eBay'd a mando-bass he had built using a standard DB neck. I asked him if he had any extra bodies and he replied he had one, which he sold me. What are the odds?
The other serendipity is that the neck heel fits perfectly into the mortise on the neck block. But said mortise is only about 3/16" deep at most. Not going to get much of a glue joint there. But the neck bolted to the olive barrel from within, with a hex bolt going up into the heel via a hole in the neck block. Just line things up and put your socket wrench through the soundhole, and do what needs to be done.
And with the new body things lined up perfectly, even with two pieces which the odds would say just had to be mismatched. Sliding the neck heel as far toward the rear of the mortise as possible aligns the bolt holes in the neck block and neck heel perfectly. I have a perfectly viable, functional instrument.
Am I a happy camper? You betcha!
