Short, sharp & shiny ... but fails to explain "Why?" 
The tracks, man, the tracks were terrible. Not only were they about half an inch too short, they were almost totally inflexible and fitting them onto the running gear ended up being a downwards spiral of hell. By the time I’d bodged them into looking not even decent, the tension on the idler and sprocket had forcefully bent the lower hull plate inwards, making it nigh on impossible to build up the lower hull - but not totally impossible. I eventually bodged that together, put it down on the table, leant back - and it promptly imploded. At which point I destroyed it in rage. And then set fire to it.
Well, that looks definitive! Is there a Plan B?
Yes, and a plan C as well. This has messed up my planned schedule but I have many ideas for African vehicles, and I’ll try to start my next one this evening.
