Our parts came in today! However, we realized that the sprockets still needed keyways to be cut into them. Therefore, we consulted Joe from the machine shop in Emerson about the best way to cut the keyways. He agreed to help us tomorrow morning at 10am to use a special tool to create the cuts.
I looked more into the Tracker video tool. We will need to make a measurement of a part of the erg to use as a reference distance in order to accurately track and calculate the distances moved in the rowing videos. Looks like another trip to Teagle!
