a drill press should work, get a centering jig for round pieces, mark it and hold the gear in a vice in the drill press. i used to have to do it that way before i finally broke down and bought a mill. currently im *thinking* about using the hs55 parts. my brother is into electronics and its amazing how CHEEP i can buy SMALL electric motors. i'll probably use the servo electronics for a esc for the time being but i do have a couple of esc's on the way from across the big pond. i had the same problem with gear sizes when i tore down my STD size servo. just too big, but he motor and electronics are still usable. im still looking into a few possible sources for gears that i have located using my brothers electronics books. just have to sit down and crunch the numbers to see if they will work. ill let you know as i find out though.
