You could try and purchase a flexhub flange (http://www.andymark.com/product-p/am-2445.htm) and a 8mm hub (http://www.andymark.com/product-p/am-flexhub.htm) the hub fits in the flange and the flange has the appropriate hole pattern for IFI and Andymark wheels.
Another option would be to modify an IFI planetary gearbox to accept the cim . Good luck from team 1325!

Or make a shaft adapter. Made with a drill and a hacksaw. Or buy an 8mm one and drill out the other end for what you need.

How does the hex hub hold the hex adapter shaft into place?

We are looking for something similar since the normal hubs are sold out.

You put the hex adapter inside the hub and put the 2 in a drill press. Drill a hole with a number 7 drill through both of them to the center hole then run a 1/4-20 tap through the 2 of them. You can then run a set screw through the 2 of them all the way to the CIM shaft.

Hope that helps.

Commonly used AM hubs routinely go out of stock at inappropriate times during the build season. We noticed 250 hubs never go out of stock. So we decided to buy the necessary drill bits, reamers, key way and hex broaches to make whatever size hub required for the application out of them. We offer this service to the FRC and OCCRA teams in our local area. Check with established teams in your area to see if they could make a 8mm hub from a 250 hub for you.
