Today I was somewhat busy with other stuff, so I didn't get much done.
In the morning I applied some primer to the slots in the booster cover tops, so paint will stick better after these are glued back together.
In the afternoon, I started the first modest steps on the utility arms. I drilled 1/8" holes in the utility arm pivot points, and JB Welded 1/8" metal rods into them. These will be cut down to size soon.
