Another spoked hub was printed to match another gear. This hub was installed the same as yesterday with short 1/4" (6mm) long screws.
A 4' x 8' (1.2m x 2.4m) piece of hardboard was purchased to be the mounting board for all the gears. Laying the gears out in the actual position they were going to be mounted was hugely beneficial to deciding the next step. Mounting them to rotate and interlock will be a challenge. For days, a suitable design has been bouncing around in my head, but while writing this sentence it occured to me, finally, that creating a low profile hub with bearings was silly, the bearings should be conected to the board so only an axle coming out is necessary. This way the gears won't need any special mouting techniques and the bearings can be kept out of sight.
