I always to look forward to seeing your progress Jim. It's a great cyclekart.

Weekly update.

I spent some time this week pondering the boot lid hinges... eventually I settled on a simple solution that may just work out as a bit of lucky genius allowing me to both access the starting side of things and the maintenance side of things. A couple of little issues to sort but it feels like progress.
I also took delivery of a caliper that looked like it would do for a hand brake and I think I may have solved that too. The photo shows the handbrake caliper in red. Its linkage arm, in blue, pivots on a bolt to the chassis sub-frame  which in turn is attached to the silver turnbuckle arm that adjusts the caliper as the disc moves in the dropouts when the chain is tensioned. The eagle eyed amongst you may recognise the components of the door closers I have spannered to bits in other threads. A little fettling and I think it will work well.
I have also added a center strip to the boot and a fake hinge line to the bonnet. I have ordered some perforated alloy to cover the boot.

Gratuitous picture of a sunset at ours this week.
