The beast has been assembled!  Minus the actual cockpit, but that's just a minor detail.  I finished drilling the base, then reassemble the UJ.  I then realised that I'd assembled it without the 4 bolts in place, swore profusely, then took it apart and re-did it.  Once that was complete, I had the exciting task of assembling the damn thing without breaking, dropping, scratching or otherwise damaging any of the sections I've spent the last 4 months creating.
