After work tonight, I completely tore down my B9. I even put the bubble and Torso back in their box and brought them in the house. Now I can redo the tread section and legs and build the new sidepanels to fit. Plus I can fit and attach the new treads.
After I fill, sand and repaint the lower part of the robot I'm going to give a lot of thought into making it easier to take apart and put together. Another thing I need to do and wish I would have addressed it earlier is to cut notches for the soil sampler. I'm not sure how to do that yet. But I have to at least make it look like there's a soil sampler.
