I'm researching alternative (cheaper) ways of fitting my robot with arms. A few creative ways have surfaced and Brad had an interesting idea of how to make arms. I'm waiting to hear back from some suppliers on alternative sources.
After work, I lightly sanded the primer I applied to the treadsection and knee plates. Then Yvonne and I applied some hammered silver to the tread section and knee plates. The paint looks pretty good. We only applied a few coats and called it quits.
