Unfortunately not. Once we saw how the notches affected how the chain seated on the sprockets, we filed the notches out so that we could get on with testing. We neglected to take photos so the evidence is gone now. Also, I am working with another team this year since we moved across town. Driving over 40-60 minutes one way was not fun.
I did some hunting around and found some aluminum sprockets with hubs made by Berg. These use set screw hubs and "pin hubs" so it may be best to broach a keyway in them.

I also found some glass reinforced nylon sprockets made by Torque Transmission.

I will give their distributors a call and see what their stock looks like.
