I bought a nice selection of small motors for some projects. The problem is finding gears to fit my needs. I figured I could find a watch supplier or something but I have not had much luck.

Can anyone hook me up?

Mamilligan, have you looked at all the aurora ho gears?

I need gears with a much smaller hole for the shaft. I might be able size up to the normal HO sized gears with brass tubing. I was hoping to find a better selection than those sold for slotcars.

Have you tried any hobby shops?
Sometimes shops carry little expirmenting kits for building motorized gizmos and such.
And here is a link of several sources...

I hope that this helps.
