First we need to drill a hole in one of the 9x12 Aluminum plates **S35** because we will need a hole of just over 0.5 in diameter for the differential pivot mount. There is already a small hole drilled in the location we want to use, but it needs to be widened substantially. Start with the drill #23 and drill the hole shown by Figure 1. Repeat this with drill sizes stepping up until you get to a drill of 0.5 in.

The image below shows our suggested progression through the mechanical build process for this project. All individual subassemblies are meant to be completely parallelizable, so each individual subassembly could be built on its own at the same time. Once all the subassemblies are finished, there is one mechanical integration process where each of the subassemblies is integrated together to create the final rover body. Note that the mechanical integration instructions are meant only for the base assemblies that were originally released with the project, and may differ when using other modules/subassemblies that were not originally included in the base assembly.

The turnbuckles must be attached to the differential pivot and rocker-bogie arm. We will accomplish this by drilling holes in the aluminum beam S16B and attaching two 5-hole aluminum bars on each side.
