so i took your advice and Kaz and "grew a set" and drilled and tapped the pinion gear myself. its not perfectly straight but it went a lot better than i expected. here are some pics. you can see how long this gear is. i used 3/16" drill bit and 6mm x 1.00 tap. 6mm set screws go in perfect. fat little stubbies, they are!
