It seems like you skip by that rough aluminum step. I know you use a lot more CAD than we did, but do you just trust that your Vex and cardboard dimensions are "good enough"? Or do you end up rebuilding some manipulators if you find that your dimensions don't work as well as you anticipated?

I know they plan in adjustable features by adding extra sets of holes and such, we may have copied this attribute when we stole their entire 2007 arm effectively....

Good point. Having flexibility with mounting points on a final piece can help out later down the road if something changes. Plus extra holes = less weight
