I spent a good amount of time researching this at one point, and as far as I could tell, to make a gear with less toothcount have the same pitch diameter as a larger gear, you take the gear with the toothcount you want and let the teeth extent all the way out until their involute profiles meet, instead of cutting them off at a given diameter (as you would to make it have it be the normal diameter).
Of course, I may be totally wrong, so someone else feel free to correct me on this.
