    Reduce the pitch of the worm gear, or increase the number of teeth on the spur.

    the gear im using is tiny, like a half inch and it only comes in 20 teeth. the only worm i can find for it is 48 pitch. im looking at https://sdp-si.com/ only so are there any other sites that have half inch or even better 3/16 gears with more teeth and worms with smaller pitches?

    What are SDP's part numbers of the gears you are using? Can you use bevel gears?
