Some of each. There is some difference in the amount of "dome-ness" but not much. The radius of the actual edge was cut to match the sharp keel on the stem.George, you said you were going to radius the "horn" at the hard corner at it's stem end, that would have been interesting to see. It looks like the edge was only "softened" very slightly? The original horn extension in video #1 appears to have a more domed shape at the end, or is it my eyes?
The briar tube extended through the horn to the base of the recessed "pocket" for the stem shoulder.In the original pipe, did the briar sleeve only go as far as the trim ring?
Yes, I stopped the video. I meant in the other direction, towards the bowl of the pipe. My understanding from what you determined, was this briar was part of the trim ring/horn extension assembly when the pipe was made, and not the shank's wood having been turned as originally thought? That it effectively formed a briar sleeve for the tenon. So it "plugged in" to the mortise drilling in the shank?The briar tube extended through the horn to the base of the recessed "pocket" for the stem shoulder.
Agreed. Have you ever worked on any of the older Larsen pipes? They used the steel tube in the shank mortise into the horn, with a separate reinforcement piece at the military mount end.How much of all that was planned and how much was improvisation to salvage the design we'll never know, of course.
