I've been doing some digging through my notes and saved pictures (more on that later), and got to wondering, how old is your most-used horn?
I can remember as a kid (early '80s) seeing folks who had horns that seemed "old" to me, with scrimm'd dates going back to the '60s. Once in a while I'd see someone carrying an original, but we seldom knew how old those were due to lack of dates.
The horn I carry most-often now was made when I got shanghai'd into running a seminar on horn-making at one of the rendezvous back in '89 I think. No one was really set up for it, so we made horns using the tools we had with us. IIRC, the original iteration of this horn was made using a knife (to shorten and scrape the horn), a hatchet (to split and rough-shape the plug), a canoe awl and a moc awl (to drill the spout and for nails to hold the plug), and a 3-square file I had for some reason. I might have used the drawknife from my repair kit too, don't recall. The awls were pounded through a split of wood and used as a compass to scribe some of the carving on the horn, finished up with my penknife.
Around 2010, the horn (and my musket) spent some time under water after a canoe wreck--maybe a week or so. Musket was OK, but the plug in the horn has absorbed enough water it split. I turned a new plug from some quartersawn pine, and made some other minor repairs.
So my horn is roughly 33-34 years old, older than the "old" horns I admired as a kid. How old is your horn?
