Additional note: When I was trimming the horn it to length I cut it to short, have no idea how I managed to do that, just not thinking I guess. As it was it just didn't look right so I decided to add the cut off piece back on. I turned a piece of Maple that would fit inside both pieces, turned the inside hollow so powder would flow through, glued and pegged it in place and covered the seam and wooden pegs with a band. Always something.
