Does anyone have a source for small gears? I'm looking for something that would fit a 1.5mm shaft. I would be buying a dozen at a time, at most. Everything I'm finding on Google is for bulk supply.
Try Northwest Short Lines.
Their on line ordering system is a bit difficult to navigate, but they do take Pay Pal and ship anything in stock promptly. They also have a design program which can assist you in creating a gear train for almost any use.
The usual denials of association.
Here is one industrial source I have used many time in the past

Can you give me an idea of what specs you are looking for? I may be able to help.
Thanks for the links. I never thought about NWSL.
I have some Faulhaber motors I want to use in making nose-hung traction motors in 1:32. The shaft on the motor is smooth, and measures 1.47mm. I assume they are meant to have a press fit? That's where I'm having trouble finding a spur gear with suitable bore size.
The output shaft diameter is 5.5mm. I'm looking to get in the neighborhood of a 1:8 gear ratio.
I looked thru my collection but sorry to report I have nothing even close to that spec. Good luck with your search. How about printing them?
