Yes I am doing a simple straight conical form. I just took a form from an internet software. Modified the base form to make it a little deeper so that my 2mm cutter form corner did not foul. Then lofted it as a 2D major circumference 32tpi to the scaled down minor circumference 32tpi for the small gear. This looks quite good. I am then doing the same with the gear form onto the 64tpi. Maintaining the same tooth pitch on the mating major and minor circumferences. This looks fairly promising.
