Well here we are, 31.2kg of Kaizen 1.0. The good news is that it moves fine, even on a very uneven wooden floor. Bad news, the pinion gear for the axe has slipped off again so I'll get that reseated back on the shaft and then I might actually have a weapon for Chatham. :P I'd say ~10mph which isn't fast but the small wheels mean it does at least get up to speed quite quickly.
