The old dowel has to come out of the neck. There's no way to get it out other than to cut it. So I did.
I'm going to put a new dowel in, so I drill out the old one. I used a 1/4" drill bit as a guide, then I moved up to 3/8" to get all of the old dowel out. The dowel is a 3/8" so that works out perfectly.
Here's the new dowel in place. It's a bit long - I cut about 1/2" (maybe 13mm) off the length.
This dowel attachment is not the ideal way to attach a neck. I found this out when I reglued the neck. What I goofed on was the lateral alignment. I was so focused on making a tight neck joint, that I overlooked the horizontal alignment. I wound up with the neck tilted side-to-side (as I say, lateral) a couple of millimeters. So I have to steam the neck apart, clean it up and try again. My neck set is also off a bit, so I need to correct that a tad too.
I'm not too worried - I'm pretty sure I can fix it. As Dan Erlewine says "practice on junkers." This isn't exactly a junker, but it has been a good learning project.
This alignment issue, by the way, is why better quality instruments use a dovetail or other joint to attach the neck - there is much more accuracy than relying on a dowel. The neck can rotate too easily on a dowel. When I re-reglue this one, I need to clamp the neck down in 2 directions. Lesson learned.
Not to mention that one of the back cracks came unglued while I was handling the body. I didn't put any patch there, but now I know I need to.
