Were planning on doubling up our wheels on the drive axle. Last year with a single wheel we had a fixed axle and attached the sprocket directly to the wheel. Whats a good way of connecting the wheels and sprocket to the shaft without using a keyed shaft. Should we drill clean through the shaft and wheel hub and put a screw through it? drill a hole in the hub only and find a way to set screw it? or is there a better way? btw we are using 1/2" diamater shafts if that makes a difference.
