Thanks, Steve and all. Generally I let the horn speak to me as I start working on it. I picked up a very rough, extra long horn from Lee Larkin and noted it was light and thin already. Sure enough the cavity went close to the end, which was thin. So I didn't have much material for shaping; the horn was too thin to have a step from the body to the throat. With rough horns, I never know what lies underneath all the "bark" till I've got it smoothed down a bit. I saw a picture of a chip-carved end plug that was fairly unsophisticated and it caught my eye. I did it in pine- next time I'll use cherry or something that will stand up better to the chisel, if I want it to look "horner-made" instead of "owner-made.
