This week has been a bit forward and backwards on the Kart.
I spent a day on Friday trying to get a pair of Vauxhall Corsa bonnet hinges to fit the boot lid and open it giving the necessary clearances. I have abandoned that idea and am contemplating other ways to secure it in place.

On the positive side...
1 I got the boot lid frame jointed and glued up
2 I mounted the fuel tank
3 I wired the kill switch and temporarily labeled it. (Synthpunk, the photo is for you ;-) )
4 I finished attaching the steering wheel quick release after a mate turned away the bit I didn't need on the end of the spigot
5 I found a badge that fit in the centre of the steering wheel perfectly
6 I have acquired an 8" x 3-1/2" silencer that looks like it may fit into the exhaust system
7 The Nomex overalls arrived.

Not a bad week but it felt like slow progress to be honest.

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.

A little Monday post work cyclekart building as my perforated alloy off cuts came through the post and I just had to.
 From a distance it should look pretty unnoticeable especially as the angle your eye can see it reduces as you are further away. When it is all painted up. I hope it will provide a cooler engine bay as I read overheating can be an issue with a covered engine bay - anyway, we will see in time.
The off cuts were not quite long enough for  the job but I need to sort out a boot latch at the bottom end now so I hope I can cover the discrepancy without too much of a visible join. Failing that I could try and match in a couple of pieces from what I have left. 3mm alloy with a 5mm hole - probably weighs less than 2mm alloy and it has taken the compound curves of the boot well.
