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.

Unfortunately the last set of photos are still on the school system, so I can't access them.  I'm sure there's a way, I just can't remember!  Either way, the base frame is now fully drilled and waiting to be countersunk, and the mini-frame that the UJ attaches to has been welded together.  I'm now taking the opportunity to catch up on some paperwork (production diary, gantt chart, etc...) over half term!

Marking out, centre punching and drilling the holes in the cross bars.  These are going to be bolted onto the frame, and the UJ is going to be mounted on top of them.

After a brief wait for some more 50x25 box section (due to the fact that I cut up the wrong bit...) the base is nearing completion!  The two rectangles have been tacked together, and the two long bits (technical term!) will be bolted on.  This mean that I'll be able to disassemble it and hopefully managed to get it through the door.  The UJ then bolts onto the plate, and it should start to look somewhere near its final form.
