that was absolutely wonderful, thank you so much for this. I am currently writing an art history dissertation on English pottery and have been trying to figure out how these lathes worked -- what a revelation your research is!
Similiar machines were used in the manufacture of parts for internal combustion engines. Specifically the camshafts and to so degree pistons. Camshaft profiles were ground using a Master Cam that would be followed by a roller. The roller was mounted on a cradle that would rock in and out allowing the cam profile to ground. Pistons are made with elliptical skirts. Some were turned with elliptical profiles mounted on the spindles the would move the cutting tools in and out.
Thanks a lot for sharing and taking your time to investigate, very interesting. I know this would be another type of lathe, but I wonder if the screw-thread at for example ceramic bed-warmer bottles also were made on a lathe.
Thank you this is so interesting! What wonderful mugs!

Awesome! Thanks so much for sharing! ❤Wish they still made them.
PS, Love the music!!
I finished my reproduction of the lathe today, test runs tomorrow!
