I like it. I have never tried threading antler. Are there any tips I should know about?
Mark, to begin with the horn has to be pretty solid or the area of pith about the same size as your bit or smaller. Same tools as horn, I do back out and clean after about every turn, Dr. Jackson's Hide Rejuvenator, lots of it as a lube.
Here are a couple of candidates both are about 1 1/8" and will work well with a 5/8s tap. The smaller one is right at 3/4s"
it is threaded all the way through.Not much to work with but somewhere along the line it will get used.

PS: Somebody told me they use CA glue on the threads once they are cut. Haven't tried that, I would think the glue would make the threading brittle. TC
