Getting there with the rear arms, Ed finished a jig and tacked up one side just to double check clearances:

And new rear discs, same weight as the old ones but 320mm diameter instead of 300mm.

After trying the double diaphragm clutch the other month, and almost getting a hernia, went hunting for a tiny pull-type hydraulic slave cylinder, eventually found one that would fit, so onto the other end:

Yes, strange shaped bulkhead with the fuel tank behind plus a requirement for the fluid reservoir to be behind the bulkhead led to a strangely shaped pedal too. Only a mock up (the ally tube is too soft to support the bearings long term, probably make a sleeved one), but seems to work ok.

And everything fell off the car again so the rear geo. jig could go on to finalise the rear arms:

Oooh, lovely shiny working thing:

FrontAdjuster1.jpg

Ooops, I, err, it wasn't me, a strange bloke broke it and ran off.

FrontAdjuster4.jpg

Then there was an incident involving a pillar drill butchering some finely machined components, a tap, some deburrers and some extra parts. I didn't take a photo of those because of their graphic nature to anyone of a petrolheaded persuasion.

Anyway, it all got back to being shiny after some TLC and some T-cut, and I think all the important bits went back in. I'm sure it'll fine.
That bit that pinged off into the corner didn't look vital.

Look, 1 whole wheel on the floor, we've invented the agricultural unicycle!

Well, the new arm revealed one stumbling block after being cycled - the existing rear geometry gave massive toe change with the extra travel we were intent on using, and nothing beneficial either. After hearing Ed swearing about it for a while I had a look and decided to just re-do the mounting points on the car and make another new arm - I've been wanting to alter some of the rear geometery for a while, so there's really no better time than when you're making a new arm.
We've removed a little of the rear camber change, and lifted the outer pivot to help with the toe curve, which now has about half the previous toe change over the travel and what is there is helping rather than hindering now. As a side bonus that brings the anti squat up a little closer to where I'd like it, and lowers the rear roll centre which should help with a little more traction/grip.
Cheap and cheerful jig to swap the pivot location over to the other side of the car, nothing fancy but it works:

And on with the new, new arms:

RevisedArms1.jpg

It's actually made the area for transmitting load around the bumpstops and damper mounts much neater so they should end up a little lighter too, added bonus!

Rear damper mounts ended up a lot neater too:

Car going back together and shiny new discs - clearance on the caliper is a little risky mind...

Not being too happy with the temporary air inlets for the manifold and supercharger, and having a spare bit of billet from another project, Ed make a small mountain of swarf and replaced the manifold one whilst I was swearing at the cam sensor (I had to make a plug for it, because we couldn't get a connector to fit it for love nor money):

Just got the last bit of plating back, got a few upgrades to the new brake calipers to make so pulling them apart at the weekend, fuel lines finally went in tonight, still need to mount the pump and filter properly mind.

Some of the bits that came back from the platers going together with proper seals, bearings and greased up ready to go:

Bit out of date again.

1 - It's been running, albeit with a whistling airleak from a gasket:



2 - Then this happened:

3 - Old 5-piece rivetted and glued roofskin is now a lighter, welded single piece effort. Much cursing and hammering was heard in the process. Sounded easier than it was, ripples all over the place to start with.

4 - Roundy Roundy bits went back in:

As did uppy-downy bits:

And her hat went back on:

5 - Set the suspension to Irish cruzin spec:

6 - Got slightly carried away with louvers. But only slightly.

Okay, maybe more than slightly:

Errm.

Haven't updated for a while due to serious family health issues/funerals - and a few heart problems of my own to boot - so will just bring this up to date a bit:

 

orkshop elves have been making new CV flanges since the old were pretty sloppy on the flanges, I'm going to have them plated to to tighten up the clearances a little this time around, as the rock on the splines a little from the plunging forces, and it wears the seals out eventually.

CV%20Flanges%20New.jpg



 

Cardboard aided design is back!
In fact, in this case, it was Computer Aided Design for the Cardboard Aided Design for the wing.
CAD^2? CAD inception? CCAD?....anyway:

wingribs2.jpg

 

 

 

Now we've evolved into PAD, it's almost structural. Almost*

RearWingRibs3.jpg


*Needs more duct tape.


 

Good news, the CV joints are here!

CVs.jpg

Bad news, they've sent the undercut 'race' ones with undersized CV balls that we don't want, as per earlier in the thread, as they're crap for wear and distort where the bolt heads are undercut.
So yes, more waiting....

 

 

 

More wing pictures time - finally got the first skeleton up to full width - need a thin sheath of balsa in certain spots just to give it some shape in order to skin it with either fabric or fibreglass to give it a structural skin, the wooden spars will get replaced with aluminium tube when it arrives, and it needs some carbon + epoxy reinforcements to go in on the trailing edge to stiffen/strengthen it, but at least it's getting closer - just another 3 to go...

RearWingElement1Skeleton-1.jpg

RearWingElement1Skeleton-2.jpg


 

Been and swapped the CV's today, forgot to get a photo but they're some proper GKN outers, but the chromoly race cages, eletropolished centre stars and balls are already fitted.
I need to hand finish some of the tracks but apart from that the rest of the prep work on the other bits already done so it should be a quick job to get them bolted up, bar coating the driveshafts in some anti-chip coating to stop any places cracks could propagate from.

Clutch pipe needs remaking as it's only a mocked up piece from old bits atm, but once we have that sorted, it can move. At last!

Won't be soon - have to give us a few weeks - as we're repairing one of the old spaceframed racers we used to make for someone else atm.

 

 

 

Inlet for the supercharger got remade to give a better run for the throttle cable and smoother transitions - still not ideal as in a perfect world it'd be curved into a bellmouth too but space is very, very tight down there - there's not enough length to do it properly. Mind, I don't think we'll miss a couple of horsepower...

NewChargerInlet.jpg



 

Getting prettier as you go through from start to finish :D

Finishing touches slowly going on, new inlet, new boost piping, heat shielding/lagging, shock reservoirs mounted, looms routed through bulkhead fittings, etc:

ChassisFinishingTouches.jpg


 

Well, that's one (still needs it fibreglass skin, has a thin* balsa layer at the minute to form the cloth over and it's allowed me to foam fill the leading and trailing edges for dent resistance)....

WingFront3qtr.jpg

WingFront3qtr2.jpg

On to the always growing list of 'additional s*it we shouldn't touch until it's finished but we're probably going to do anyway' - the front mudguard mountings tubes are going, they were originally left separate to the damper mounts so no damage occurred to the suspension if a mudguard got ripped off, but we've worked out a smaller, neater way to do it which gets that curved tube out of the equation. Should be lighter, look a lot neater and gets the tube out of the way of the wing endplates.
You can see the new nerf rails and front bumper coming together too.



[small]*So thin you can see the ribs through it, saves at least 10 vital grams of weight![/small] ;)
