BB-8 want-to-build thread (apparently I'm calling him BB-8)

Still need a name.  I've decided to start with a nominal 50cm diameter sphere.  I'd been working along those lines because I thought it was close to my measurements and a nice round metric # and the builders are from the UK and not used to inches.  However I was a little worried it might be bigger, some photos seemed to maybe look like 21" or even 22".  But cyborg on Astromech posted several pix with good side-by-side shots.  The first I measured at exactly 0.5m, the others slightly bigger, but I was able to convince myself that the perspective was a little off, and so he's probably smaller than my bigger guesses.  They were all in the ballpark though.

This is the "best" of the pix:
