Internal Gears, Practical Applications

[precisionmetal]

Anthony,

I'm the guy that cut the 0.1 module external gear in the photo above.

I've cut many internal gears and splines... from very tiny, up to very large.  All via wire edm, and often from pre-heat treated material.  I also have a #7 Fellows gear shaper, so that would be another option if I have a cutter of the correct DP/PA.

If it's something that could lead to even a short run, I'd be happy to cut a sample.
