Devlog #13 - Drivetrain System/Day-1: With the very start of making this section, today I built the rear differential cover, the u joint (universal joint), and the pinion shaft, all part of the main rear differential system. I went ahead and started working on this section rather than making the other track bars and all that stuff, because I kind of wanted a “reference” to build on, (aka a better picture of where the other parts were gonna go). I think about the hardest part about today was kind of planning how to do this. To me, differentials look like a huge mess to look at; I was super confused on how even the gears connected and worked with each other. I definitely am making it harder for myself by building the internals too rather than just the externals, but hey; I guess I really want a challenge!
