My little motor also had a threaded end on the shaft. My wheel is the ground down hub from the squirrel cage/blower that you didn't buy.

Correct diameter will depend on what RPM your motor needs to turn to generate the right voltage, say 14v.

I did mine backward: I ground the hub down first, then tested to find out if it was the right size by pressing it against a moving bike tire while it was on a stand, while reading voltage off a voltmeter.

You should start a new thread with pics. I'm sure others will want to see what you're up to.
