After I mounted the dynamo to the marvellous machine it had a little shake which gave me some pause. Because the piece is to travel many thousands of miles in the back of a transport truck I became worried about a failure. The solution was to create another bracket which attached to the top portion. As I looked at the space it became apparent that if I added a bracket here it would interfere with the next gear I was going to add.
I decided to offset the gear to the left and use the same bracket to hold it in place. I hand held the gear in position and then took some quick measurements.
