Yeah. The metal ones were 800Hz tractrix. I never liked them for reasons I can’t quite describe. I could always hear them, which I couldn’t with the previous ones and can’t with these.
I now have plans for the 2441s as well, which will entail lots of glue!
Today I’ve been doing maths and spreadsheets, what fun!
Going from a point cloud to a mesh then another mesh and then curves seems bloody stupid. The mesh steps make no sense. And they are really difficult to implement, they keep fucking up.
So I’ve been trying splines. These are just equations for curves. Fusion can import a spline as a sketch object, so I’ve imported the throat, the mouth and a number of lines along the exact profile of the horn.
Then you can use the loft function to connect throat and mouth, along the path of the horn profiles. And it works…
The eagle eyed among you will spot that there are some striations along the path just up from the throat. You smart arses can fuck off, but I might try to fix that soon.
