We have legs. (And we know how to use them.)

So last night I put the first leg on. It was pretty awesome. I had originally planned on feeding a bolt out through the frame holes, through the shoulder hub, and into the leg sockets, but that proved to be a royal pain in the butt getting everything lined up properly. So instead, I snagged some threaded rods and put them in the legs first. Then I dropped the shoulder hubs down onto the rods, put them through into the frame, and fastened them with nuts and lock washers, thus:

Due to the 4-6 difference, I had to do some extra drilling and only had 4 holes in. But if 4 is good enough for the aluminum legs, it oughta be good enough for the wooden ones.

Anyway, while I had the dome ring off (I had taken it off to put the skin mount points on before the legs went on), I finished off the utility arms. It seems I hadn't noticed it but the frame kit came with the proper mounting hardware for the arms, so I went ahead and put 'em on while I was at it. So at the end of tonight, R2 was looking like this:

So anyway, the next step is the center ankle. It turns out I had the hardware for an aluminum center ankle, but there's a different one for the wooden version. Which I didn't know. But the frame guy is swapping me this week, so hopefully I'll have the proper hardware in my hands soon, and I can put on the center ankle, followed by the wheels and foot drives, and R2 will be standing on his own 3 feet. Can't wait.
