The ID of the 45 tooth is .5" They are Martin steel gears and some sort of steel shaft.
Thanks.

i can see it looks like you are trying to use the white paper on the gearbox from andy brockway (as it seems). The best way to attach it (from my standpoint) would be to either heat shrink it on (in a kilm) or by using say liquid nitrogen to shrink the metal and let it warm back up to room temp for the metal to expand again and bind to the gear. Be forwarned through heating and cooling the metals may cause stress and strains that are not intended for the material use and may cause some problems if not done correctly.
