i have few questions:
1) if have dc motor 10 tooth spindle gear how go matching spur gears etc. mathematical 'instinct' tells me spur gear have have multiple of 10 teeth or number of teeth has common factor 10. mistaken.
2) cannot believe how friggin difficult seems find source of heavier duty plastic gears/cogs largish diameter (5 - 6 cm or so) , 4mm diameter centre hole. can point me in direction of site can find sort of thing. ebay appears of no here....or else using inappropriate key words.
3) there major issues meshing brass spindle gear heavier duty plastic spur gear?

1. number of teeth not matter that. pitch & pitch angle crucial things consider first. number of teeth determine torque , speed ratio. 1 full rotation of ten tooth gear spin ten teeth of ever number other gear is. however, 1 consideration not want ratio exceed 1:80. don't want less 10 teeth or greater 250 on individual gear.
2. have searches included small nylon gears?
3. yes. not when comes desired ratios. 2 opposing materials have negative effects on life cycle of gears. effects performance. smaller gear, , slower speeds, less run major issues.
