Due to some offcuts of 12mm square bar from the frames of our Heisler loco becoming avaliable I'm going to make some small test runs of making some atomizers for it.

I can't find any open source CAM software for outputting to a lathe so I'm going to be writing the G-Code by hand in gedit. I'm getting the design from here which I've found to be a very good resource for info in the shay and heisler locomotives. I am making some changes to simplify construction with the avaliable tools (rounding to the nearest metric drill size).

I can post up some CAD files of the proposed design and the G-Code if anyone is interested.

Cheers,
Rex
