CIM direct drive

NOTE: I am not completely sure this will work. We did something similar and didn't notice a problem, but you never know. Maybe somebody with more knowledge can help me.

In 2006, we took an ANSI sprocket and wrapped the CIM shaft with some tin to make it close enough to the same size as the ID of the sprocket so the sprocket would spin fairly true when mounted. We then used the setscrew to hold the sprocket on. The sprocket definitely wobbled when we turned the CIM on, but the number 25 chain never fell off. So it works, but is not a very elegant solution. Thinking back on it, another way would be to take a sprocket with a smaller hole, like a 5/16" bore sprocket, and then bore it out to the size of the CIM shaft. Then, run the set screw into the keyway of the CIM. I am pretty certain that the CIM doesn't produce enough torque to make the setscrew fail. Does someone else know if that is true?
