Saw these, and thought of you!

I like the WD40 can.

OOFT !  Tried to get a PDF uploaded, but didn't find a way to do it.

If you can see the detail, this is a Metal propeller blade "milling machine" manufactured and used by Ratier Figeac France in about 1940. It copied a 'master' blade and finish profiled 4 aluminium alloy forged 'blanks' mounted between two chucks. I can't quite make out where the 'master' was. Ratier are still in business today and make many diverse parts for the aero industry.

This machine seems to work on the same principle as used to mass produce clogs (or sabots) before WW2. A linkage caused a ball to follow the surface of the rotating master pattern, and its motion was copied directly to a ball cutter on the rotating lumps of wood. The machines seem to be preserved in several museums in France (and quite likely, elsewhere, too).

Seems that the Scanify thing is no longer available. However, you can create 3D models from a series of conventional photos using products like Recap 360. Some of the examples are pretty impressive.

The Shapeoko has been around for a few years now – one of my interns in Canada built one almost 4 years ago. Nothing particularly special about it, being a CNC router like many others out there. Many of these machine seem to be closer to 3D printers with small router heads rather than CNC machine tools as such but there is a whole spectrum out there from one extreme to the other

Greenwood and Batley used to make copy lathes which machined things like rifle stocks and clog soles from solid. They had a whirling cutter which was moved back and to by a linkage copying a master, whilst the blank and master rotated in unison
