John:

The projects that I was seeing online for Tractrix petal horns were usually not "wrapped around", and most I saw were terminating at 90 degrees at best. I don't think I want to turn horns, and I am tempted to spend the time working OT and just save for horns from a company that is set up to custom fabricate. (I have a bad habit of putting 100's of hours into DIY projects, when sometimes I probably would just prefer to get the end result! For sure, sometimes I spend more doing it myself when I count tools and finishing materials, so I have to be sure it's going to bring more enjoyment than frustration.)

I believe I have a graph here of a tractrix equation that is not truncated but a complete solution set, save for the throat opening. The calculators I have for tractrix stop at 90 degrees, and I would not want to go through the trouble of a tractrix only to add an arbitrary radius at the end.

Turns out I have one "good" 2441 with original aluminum and one which now has a repaired throat and need to be reassembled. I was overestimating the difficulty. The thing practically centers itself on reassembly - except I am not sure if they intended for there to be a space between the pole piece and the shorting ring of the top plate. I will have to look into that further.

Cheers,
Presto
