I have often day dreamt of mounting something very similar for model engine gears on my CNC mill. Although, with the single point method I had though about, would be to create a small CNC involute profile grinder first. Then I'd like to create a small spindle mounted shaper to stroke the cutter. The gear blank could be mounted on an indexing table below. That sherline RT looks about perfect for this job, but dang, that is about what I paid for my 12"RT many years ago.
The reality is I have very little spare time as it is. So, back to dreaming it is and envy those who do have the time.
