musical instrument manufacture or how horns are made?

I just came across this video on Facebook, and although it's the manufacture of a musical instrument, I could imagine that phonograph horns were made in a similar way. The horn is made right at the beginning of the video.

I think the techniques are similar, especially the brass bell and body of an all brass horn. Also, just the bell on a B & B horn. I have a buddy in my area who restores brass instruments and he restores my horns using these techniques shown in the video. Very interesting video. Thanks for sharing.
