Someone should chime in with a source for a Cad program to create the
profile file.

That would be great!!! I've got a local guy I work with on wire EDM
extrusion dies.
If I had the software to generate the profile he could probably do it.


Give the complete specs of the gear and the file format you'd like and I
can easily generate a solid model.

3D - .ipt, .iges, .sat, .stp, .stl
2D - .dxf, .dwg

That's what RCM should be about. Well done, Ned. I nominate Ned
as RCM hero of the week without regard to his politics or how many
guns he may or may not choose to own.
