So I spent the day "and most of the night" doing final assembly on the framework. Epoxied the joints, putty in the gaps, sanded and such.
I took a level to the frame and made sure that the frame was level, especially the side braces where R2's legs attach. After I was done with that I threw a coat of Rustolium outdoor wood paint "Blue" on the entire thing. Next up is going to be the legs, which luckly are a significantly less stressful build.
