There is a fellow in Portsmouth NH that built 2 replica Rose Engines.
This is a variant of the Holtzapffel that does essentially faceplate
work- as on the back of a pocket watch. On these the headstock is
mounted on a pivioting base so it can swing back and forth. Where you
would expect drive belts on a headstock there are cams that can make the
headstock rock.

He gave a great talk at one of our NEMES meetings. As I recall he built
2 with the idea to keep one and sell one. I believe he said it sold for
about $40K.

There was a convention of Ornamental Turners in Kennebunk Maine a coule
weeks ago that one of my friends attended, so there are folks still into
this field.

To many good things to do, so little time!
