    Fascinating — that the spindle is being moved laterally — as well as indexing — to 'bump' into the stationary milling tool.

    Thanks for pointing that out that the spindle is moving in and out, I missed that ...that is awesome !! I also missed the belt driven milling cutter the first go round and was really scratching my head wondering how it did that ?!!

    Thanks for sharing I love to see how things work

    IIRC Lindsay Publications had texts on Rose Engines. A serious mistake in not collecting a few. They're capable of all kinds of ornate patterns, for flat or contoured profiles, since 1600's, probably earlier.

    “Holtzappfel’s Turning and Mechanical Manipulation” (5 volumes) published between 1880 & 1900 is a real mine of information. My late friend, Ken Gaines, kindly lent the set to me. A modern reproduction. I have not been able to buy the whole set, unfortunately.

    Stumbled on this recently. At $84K, a bit rich for my blood, but still impressive.

    Incredible! Almost like a mechanical — and mechanically programed — CNC lathe.

    $84k. With a lot of ornamentation on a machine tool, clearly for descendants of Louis XVI and commensurate disposable income. Rose turning isn't a big industry, so there is demand, but wonder how many hours are needed to run for return-of-investment, let alone profit?
