Hydraulic Lathe Tracer

More for visual FYI purposes (spendy) but these have always fascinated me. Basically you make a 2D pattern which is temporarily mounted relative to the metal blank. Then then the tracer mechanism basically copies it as you traverse the work. It a bit more complicated then that because you are making successive feed passes just like regular machining & that's where the hydraulic following comes in. I guess you could say 'analog CNC' :) Good for complicated or ornate work or even multiple copies of the same thing. Keith Fenner has some vids of his in action.

Keith does have some interesting vids on those pattern followers. A Cnc refit to a standard lathe would cost about the same as these followers. Steppers, controllers, computer....
