Today was a whirlwind day of machining and assembly and final testing in preparation for MS10. We had to lathe down the axle for the swing arm because it was sticking-- it ended up that we were a couple thou off of our design parameters. The gears that we are interfacing between the metal gear motor and the swing arm axle may not work as well as we though they would. Larger teeth, and possibly multiple gears in a herringbone pattern, would definitely help the strength of said interface.

Other than that, assembly goes well. Everything fits tightly as per the design, although using through-bolts instead of threading the plexiglass is an annoyance.
