I mentioned earlier in this thread that I was also building a vintage style neck (truss rod adjustment at the heel). That one has been on a back burner since I was unable to find a suitable anchor for the truss rod. The anchor mounted on the truss rod has to fit through the 3/8 in. hole in the headstock and lock into the wood somehow.
I was unsuccessful after contacting StewMac Customer Service. I was basicly told "Don't have them. Don't know where to get them". Warmoth sells a vintage truss rod but not just the anchor. I went so far as to contact Melvyn Hiscock inquiring about the one pictured in his book. He wasn't able to help much. Said "they" had had several made up special several years ago.
Yesterday as I was browsing around the special parts drawers at my local Lowes, I may have found my anchor. It's a
6-32 knurled nut. I bought a package of two ($1.05). When I got back to Jack Ranch I drilled and tapped it 10-32. The knurled part does fit through the 3/8 in. hole.
......
I decided to do a little test with a small block of hard maple. Here I've drilled a 11/32 in. hole followed by a smaller 1/4 in. hole into the end grain.
......
A few taps with a dowel and a hammer and the knurled part is driven into the maple.

Here's the block after removing the rod. Looks like it just might work.
