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.

Real craftsmanship here, Jim! It looks amazing
I don't want to bore you all with the details, here. But if you are interested, have a look at my blog https://peteskart.blogspot.com/

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.

Weekly log.
Lots of little jobs this week.
A couple of shots of how the boot hinges work, Position one for starting, position two for maintenance. Hinge pins from master cylinder pins with split pins for easy removal.
Time spent putting heavy duty valve springs in and not a few expletives uttered in the process. The valves have split collets and aluminum caps. Getting the collets back in involved losing them several times, taking the crank case cover off, shaking the engine upside down, employing the wife, and generally getting frustrated before "getting the knack".
No amount of YouTubing can give you "the knack" :-)

One positive from changing the springs was finding an extra nut that the factory had included loose in the rocker cover! That could have caused some aggro!

(not so ) common lizard on the marsh

A few hours preparing side one for the final skin and an added spring to the pedal.

That's really nice Jim, The quality of the workmanship looks outstanding like many of the new builds on here at the moment.

Thanks for that Jim, it is a bit experimental, but I suppose that's what CycleKart is all about. I know where the filler is ;D so it ain't perfect. I am not a million miles away from the engine starting, I suppose the proof of the pudding is in the, er, driving?  ;D

I'm on holiday this week, so besides the "melon" list (Honey-do) and a bar I'm knocking up in a mates man-cave it's time for side one, a job I have not been looking forward to. So far so good, but lots could go wrong yet.

Weekly progress.
Side one trimmed up.
side two glued and trimmed up.
Both cockpit internal panels fit, glued and trimmed.
Grill cut and starting handle ferrule fit - but not fixed.
One of the bonnet panels cut - cant fit these yet and I have had enough for the day as the garden and a beer call.

The starting handle ferrule is a stainless sliding cupboard door pull left over from a job, holed and rolled on the wood lathe - I have another one or two which I intend to use for bling on the boot.

Thanks to Rhys and Synthpunk for their earlier comments on body torsional stiffness, double skinning the cockpit has made the whole thing stable enough to inspire confidence. :D

Another week at it, along with work, picketing work, finishing off a mates bar in his mancave and a bit of shooting targets.

Progress.
> made the seat frame
> Turned a handbrake lever out of an off-cut of oak worktop
> Used an elbow catch epoxied into the handle and a bike brake lever to approximate a period lever -it should work "fly off"
> Put a stainless corner trim on the rear after a bit of gentle reshaping in the wood vice to provide a bumper to the corner
> trimmed out the center tunnel and added the ply strengthener to the brake/accelerator mounting (belt and braces)

I think that the handbrake might end up where it is in the picture. It is on the other side in the original car but having sat on the "wrong " side of the car to drive abroad on many occasions, the handbrake is always the last thing I get used to. So to the left hand I think it must be.
