Pins/Rods/Motor Completion

After changing a few designs for our motor, we assembled it. With the input of Mohamed, we decided to put "glove-like" material between the acrylic face and the oven wall  to prevent as much heat as possible from getting into the acrylic motor box. Our box will require two power sources, one for the motor and one for the Arduino:

Aiming to put the rods 120 degrees from each other in the inner ring, we threaded the ends of each of the three rods:

At the same time, we aim to machine the shafts on each of the rings today, 6 total, using the vertical machine. Given the large nature of the outer most ring, multiple supports were need to reduce the movement and vibrations associated with the cutting.We ran the tool at a feed setting of 5 and 1500 RPM:

As of 3:40 today, we were able to fully manufacture the outside ring and its spins effortlessly:

Ring Machining

Machining of the rings today out of of a half inch thick sheet of steel. We first cut out a piece of acrylic for the jig on the CNC machine:

During the machining, the support structures were tapped by Andrea and Dan:

In order to begin the machining of the rings, it was suggested that we drill and tap 4 holes into each of the three rings and attach them to the acrylic jig below.this ensures that he rings will not move during machining.

Machining would continue until roughly 7 PM, at which point, the first ring was finished and the inside of the second ring was in progress:
