Yeah, solid advice, John, and we have been much more rough with it off camera. We broke it in starting to more heavily test it, so I suppose better in testing than in the arena after travelling thousands of miles!

PJ, we're thinking of drilling out the threads on the drill shaft as we'll never get the right bolt again, or certainly not for use in this machine (would break in the same way). Remember it's a weirdly sized reverse thread bolt, which we can't find anyway, let alone a high tensile version. And certainly not within 3 days along with everything else.

We're going to drill the threads out and stick a 6.5mm steel tent peg in there and bodge something up. We don't have time for anything more clever. As for welding, it's on a minuscule scale and we can't weld with any confidence anyway. We risk wasting time and/or ruining the tiny sprocket. We could *potentially* find someone to weld it for us, but again, with a day or two to do so... meh.

We'll work something out by the end of today and hopefully by tonight we'll know if we'll be able to fix it in time.
