Next came the more difficult work, designing and cutting the base. This process took a lot of time in class and out of class to complete, so I will briefly discuss each part of the process to quicken things up, by excluding some of the pointless Onshape sketches and just showing each product.
The pictures to the left are our sketch for the first part of the base. On the second picture there is a clear hole cut half way down, the third picture shows four relatively circular objects. These objects when put together form a gear to rotate the cannon with, notches are made at 0 degrees, 45 degrees west, 45 degrees right, 90 degrees left and 90 degrees right. The right two, have the same diameter, and are stacked on top of each other so they can be placed on the center object, with a slightly larger diameter. After being glued together, the three objects now made one, are placed freely in the dip in the base, while the last part lay to the side. This can be seen in the last picture.
