Re: Mounting Sprockets to the Rover Wheels
With the thickness of the spacer and sprocket, a 3/4" bolt would not penetrate very far into the hub. As many have pointed out it's best to either put a bolt all the way through and use nuts or use long enough bolts to almost go thru and tap them in. When the robots are on carpet and they take a side impact, the stress is distributed to all the wheels. With drifting this year the robot can hit the carpet with only 1 or 2 wheels taking the impact.
Beware of the carpet.
