Making BB-8 (v2) - Improving the Head - Part 7

In part 7 of how to make a BB-8 I work on the head being heavier than I'd like, so much that it affects performance. I change the way the head support structure attaches so that I can lighten it, and then I hack away at it to make it lighter. I swap the 2000mAh battery for a lighter 150mAh one. And I replace the deodorant ball casters with much better, but still fairly lightweight, Pololu casters.
