4 to 6 inch diameter gear to match stepper #27964

[verobel]

Fellow stampers..
Do you know where I could find gear(s) to match the 27964··stepper motor sold at parallax. I am looking for 4 to 6 inches in diameter. Material could be nylon or brass.
Thanks, John

I don't think that motor would have enough torque to push something that big reliably. You probably won't find a gear that big with only a 3mm shaft bore size, most likely 1/4 to 3/8 in. Have a look through this site, it will give you a good idea on what is available. Plastic / delrin are the best bet.
