I just wanted to share a picture of the jig I set up to shape the heel of my neck to match the rim. I had a luthier do it on previous instrument, and I see now that it is not so difficult as a DIY even by somebody like myself who has little experience with musical instruments.

I just used a piece of 1/4" wood to set the angle by placing it at the right spot on the neck, and hand rotated the rim to sand the heel to shape.

Clever and simple Robert.

Here's a photo of the one I just made for the drill press - same idea. It's mounted on a "lazy Susan" bearing I had spare. Figuring out stuff like this is one of my favorite parts.

I designed and built two jigs, one for re-cuting the heel angle and one for re-drilling the hole angle for dowel stick.
I made up a number or different diameter sanding drums.
They seem to work.

I made this jig a while back based on a few examples, but I got the scissor table idea from Ryan Hardison (he does great work!).

My vague recollection is that Ken LeVan and maybe others recommended that the radius of curvature or the neck be just a tad smaller than that of the rim. I understood the idea as being to assure a firm, snug fit after the wood does its thing.

I remember that, too, why I made my sanding drum a shade smaller than 11". Now I just have to get my rims to come out just on 11:)

I recently got a scissor table something like David's (sold here as a motorcycle jack), was planning something similar.

And yes, KLV was a very generous man.

I just hold the neck in a vice and carve it out with a hammer and chisel. To finish off I sometimes use sand paper or a rasp. It took me about 10 hours at the start but after doing the first 50 banjos it only takes about 35 minutes. A jig of any kind doesn’t work for me because I make the neck and dowelstick as one piece. Making it in one piece gives the neck more resonance which is important considering my banjos doesn’t have a headstock. And yes my default angle is 3 degrees :-)

Now I need to get the double-sided carpet tape off the old rim I used.

From the unsolicited advice* dept., in Wet Spaniel's Off-Topic thread "Old Rifle Clean Up," Groundhog John mentions "Easy-Off" [oven cleaner]. 

* well, not advice  per se .. it just came to mind.
