Well last we saw I was gluing on the new back with fish glue. After sitting a few days I came back to it and had some pretty major separation, so I got to do it all over again. After posting my problem on OLF, JJ Donahue offered his experience that fish glue requires being stirred well before use. He had done some test joints and had some failures before he started stirring it really well. So live and learn, it's on solid now.
I tried the egg white pore fill method and still had major pores after two tries and found the egg white really tough to sand back to wood, might be my free ranging country eggs.

So then I did the shellac and pumice which did the trick but had lots of problems with scratching from the pumice showing in the shellac, so level sand to get out the scratches. I'm going back to the tinted spackle which I've used several times before. I learned this from Robbie O'Brians Luthier Tips du Jour series on youtube. Rub it in with a piece of burlap, fills fast, and sands back quick and easy.
So I used Permalyn gunstock finish, an oil/varnish, rubbed on with a small piece of paper towel, many coats, and it turned out nice.

Got the fretboard made and fretted. This is one of Ed's 2nd grade rosewood boards with some nice color and grain patterns.

And I cut the bridge out of another one of those fretboards.
So I've got to fill and finish the neck and then wrap it up, getting closer.
