Hey guys, I'm looking into building a bot using either the GM6 or GM7 (they can be found here: http://www.solarbotics.com/motors_accessories/gear_motors/
). However, these GMs have a 2mm output shaft. Solarbotics (i've also checked hobbyengineering.com, pololu.com and robotshop.us) doesn't carry any wheel specifically for this shaft. They've recommended using this wheel (http://www.solarbotics.com/products/rw2/
) which uses a 3mm shaft and using some 1/8" brass tubing (say 1/4 of a tube) to shim the shaft along w/ a locking screw.
Has anyone successfully done this? Or does anyone know of a wheel that fits a 2mm shaft? Or maybe is designed specifically for this motor?
Thanks in advanced.
