| The cam wheels push a rocker box back and forth, and as you can see from the pictured engine, every time you want a different pattern you have to create a new camwheel (Bill's first camwheel was hand-cut from lucite and was a project in and of itself). And it seemed like an obvious thing to propose using an arduino and a motor to push the rockerbox back and forth with a lot more flexibility. (Bill has since discovered that the original technology has been somewhat preserved by the Society for Ornamental Woodturners and plans for various cam designs are available, but before we know that, a digital test system to figure out how to eventually design the cams made sense). And of course that led to asking why not put all 3 motions (radial, Z, and rotation) under computer control? Bill said "you should give it a go" and someone was dumb enough to say "sure, why not?" :-) | The cam wheels push a rocker box back and forth, and as you can see from the pictured engine, every time you want a different pattern you have to create a new camwheel (Bill's first camwheel was hand-cut from lucite and was a project in and of itself).

| - | I was fortunate enough to have the guts of a sherline 3 axis platform that eliminated the need to figure out a lot of the mechanical side of it. And I had a rotary table that came with my Taig mill. After a few false starts I had a prototype running with a Uno running three small stepper motors via Sparkfun easydriver boards and a spring-loaded pen holder. | + | I was fortunate enough to have the guts of a sherline 3 axis platform that eliminated the need to figure out a lot of the mechanical side of it.
