Re: CIM direct drive

We have used 5/16" bored gears/spockets and a 3/32 keyway. With a little filing, they fit right on the 8mm CIM shaft and then get a piece of 3/32 key and file it to fit. We've made 3 types of transmissions this way and also used this method for our ball shooter in 2006 which used #25 sprockets mounted on the CIM shaft. Never had a failure... yet.
