I had originally plan to file a large octagon spout and inlet silver filigree panels on four of the sides. I was unsure if the walls were thick enough for this, so I did a short octagon tip followed by a candy cane/spiral pattern. It worked out nicely.
Thanks for the idea, FL flinter.
The yellow tape shows where I'm going to make silver filigree bands. The horn has a two piece butt plug. The inner plug is glued in with epoxy and made 3/4" ash plank. The core isn't cut out jet. The outer plug will be of 3/8" black walnut and rimmed with a silver filigree band.
I'll post pictures when Ive done the silver work.
Best regards
