Some of you have been watching the development of an air motor/steam engine that I designed with as far as I know, has no allegory in reality. It's certainly not an improvement on any existing design and it kind of stupid, as far as engines go.
For those that haven't seen the animations, here's the HMEM link:

Well, with the design more or less worked out, it's time to build Camgine!
I started with the most difficult part: the cam plate. If I cannot make the cam, then there's not reason to continue and it's back to the drawing board.
To make the cam plate, I first needed to make a fixture so I can hold the blank and transfer it from the lathe to the mill.
So I turned a piece of barstock, drilled/reamed/tapped some holes to mount a sacrificial aluminum plate. Note that I used a Sharpie to mark the clocking of the barstock to the chuck so I can put it back in the same position (hopefully) keeping runout issues to a minimum.

The waste plate is a pieces of aluminum stock I has laying around. Again it was drilling / reaming / tapping some holes to mount the waste plate to the roundstock and the part blank to the waste plate.

Bolting the two parts together, I could drill/countersink the holes in the part blank and mount it to the waste plate and off to the lathe...
