Well I actually managed to get somewhere today, the epoxy went on lovely.
I've still got a few niggles to sort out but relatively minor stuff.
Tomorrow may yield a repainted engine bay, which would be a might fine thing as I can actually srat bolting things back on the bloody heap such as the steering rack, brake servo- I'm not using the old hydraulic "bomb" type, instead I'm using the ones fitted to the audi 100/80/90/coupe quattro etc so that also means I can start fabricating up brake lines and sorting the runs out.
About time as well.
Todays progress.

Why are you not using the bomb? I think it's a good bit cheaper on a WR than MB or RR.

The bomb was a pain, too much extra complication when a vacuum servo does the job and frees up a lot of space, its the same method a friend of mine adopted on his 200 turbo quattro 20valve rally rep wossername, it works ok for him so itll work for me as I've used the same setup previously.
Photobucket blows.
Flickrs no better the photos dont show up even though I've posted the urls in img tags, I dont get it????...

Yeah Dean the epoxy will be wet flatted, its gone on pretty well so minimal work needed and the colour and clears right over that.

Try imageshack, they're supposed to have unlimited bandwidth!
Or simply upload a piccy off your hard drive using the link top right in the reply to topic box. Never had a problem with this approach. Make sure each pick is less than 2meg and you're away.
I use Microsoft picture editor or some such freebie that comes with windows for compressing.

Aside from that, when set up properly the hydraulic system is superb and very powerful. The so called bomb is an accumulator that stores pressure so that you get umpteen goes at the pedal even when the engine has stalled. Much safer!

A wee word of warning old son. The main reason the turbocharged cars have a hydraulic booster system rather than a vacuum servo is that when the turbo comes on to boost you have no vacuum, so you have a slight problem stopping!

Thanks for the good advice Jith, I was aware of that issue as its something I've come across a long time ago in a non turbo renault when left foot braking with a partially opened throttle.Aside from that, when set up properly the hydraulic system is superb and very powerful.

You get a couple of pumps and then nothing...well very little.
Quite scary if youve never experienced it before.
My method of dealing with it is to incorporate a vacuum canister probably under the wing to act aa a vacuum reservoir and supplement whats in the brake booster so it wont be an issue then, less complication too.
Further to the wise words of Jith, honestly I'd leave the brake/hydraulic system as Audi designed it if I were you. It's simple and more or less maintenance free.
Quite apart from anything else, if you ever want to sell the car, I suggest that anyone who knows their Quattros would probably have serious concerns if it's fitted with your vacuum system (I would).
Anyway, on with the show!

Indeed, iwouldn't ditch the bomb unless a twin master and balance bar was being installed. then you really save some space, as everything can be inside the car, with a hose to each corner if you like. Servos, including the bomb, do not increase brake efficiency, they only reduce pedal effort.Quite apart from anything else, if you ever want to sell the car, I suggest that anyone who knows their Quattros would probably have serious concerns if it's fitted with your vacuum system (I would).

Sorry about the sporadic photos, I'll hopefully sort it permanently soon.
Well I spent most of today respraying the engine bay out.
It took 2 and a half coats of basecoat to get it covered correctly, no issues with it, looks fine I think.
This is just the basecoat.
Since its water based basecoat it takes a little longer to flash compared to the usual stuff you might use so its taken most of the day to get it done.
With the basecoat ready I put on a couple of coats of properly catalyzed clear.
Its come out as well as I wanted, so a few days and the front suspension and gearbox plus the other items can now go back in. Whoopee! Progress finally.

Well I got the front subframe reattached and the car sitting back on its front wheels for the first time in months, also fitted the fusebox, fan and its little domed grille.
I have a pair of new "limit stops" coming on monday, they prevent the struts dropping past the towers at full droop, originals were damaged/rusty.
I cant get enough of this colour and the paint finish, its hypnotic almost, very nice how it changes colour depending on the light.
Should have the door apertures resprayed this week too.

Bit late but just copy and paste the full BBCode, usually using the middle of the medium sizes, and you get, Flickrs no better the photos dont show up even though I've posted the urls in img tags, I dont get it????...

Not strictly right for that year of Quattro but I'm certainly not grumbling. (Although personally I'd have gone for the Llahsa Green.)Hopefully these pictures might last a little longer, I resized them right down to about 45 kb.....
Weathers been dire so unable to do much of anything, still we had a couple of days where it stopped precipitating for a bit and that gave me the chance to work on some of the bolt on parts.
Mostly stripping off dirt and paint and oxide and rust, repainting ready to refit them.
I figured if I do them now, when it comes to putting it all back in one lump itll save me some time.
Id started out doing anything that was going back on and that wasnt good enough as it was so that was everything then!
Boot hinges were stripped and blasted and repainted in the same body colour and clearcoat as the rest will be.
The stainless brackets I made to secure the removable front panel, I could have left them eau naturelle but then theyd stick out , not the intention so body colour also.
Engine mountings were similarly stripped off of all contaminents and epoxy primered then coloured and cleared.
The radiator cowl was in a state and a half so I spent a day or two getting all the old paint and rust off before epoxy primering that too.
I briefly considered going satin black on it and letting it be at that but my clearcoat obsession got the best of me.
I also made some new rubber bypass flapper whatsits and fitted those to replace the mangled wreckage of the old ones.
Just about everything has been done in the same manner.
Offside inner cv heatshield.
My reason is simple, painting parts means theyre easier to clean when in service, they dont oxidise and they dont rust, its all part of the plan to keep it looking good for longer.
Its far easier to wash off dirt and contaminents when the surface is as slick as some of these parts are, I figure long term itll stay cleaner and since itll probably never be sold, just handed down it matters not if its unoriginal.
I bought some new strut top caps and the steel cups called a limit stop as mine were shot, the plastic was off the one and they were plain nasty and covered in rust.
Looking at this engine bay shot you can see on the firewall the brake servo mounting position on the left and right.
Normally the one on the drivers side isnt accessible and its closed off with a bolted and tacked on cover, a consequence of using part of the coupe gt and cq shells, but one which is going to work well for me in my quest to keep the bay tidy and tight.
Using the same brake parts, servo master cylinder and proportioning valve as you get on the cq it means I can switch the servo position over and have a direct acting pedal instead of the old Ur's relay lever apparatus that introduces pedal slack and takes up under dash space.
I used the very same setup on my old coupe gt, converting it in the same way although the pipe runs wernt as neat as these will be.
I used the now vacant servo mounting hole in the passenger firewall to attach a plate and the proportioning valve to it.
Thatll keep it close up against the firewall and out the way of the exhaust side of the bay where itd normally sit somewhere over the manifold cluttering up the scant space there, it also means a minimum of pipe runs, you can just make out the one pipe to the valve as I painted it black rather than leave it copper and hence liable to go all green and icckky later on.
Since I'm almost out of things to paint my efforts now have to go fully into rebuilding Phils Urq engine, after I finally got the block bored and honed and new 3rd oversize pistons ( only ones now available) to replace the destroyed one after a valve head went awol and pretty much wasted the entire thing.
Fun.
