Those hard to find TVR rocker covers
Discussion
Hi all,
I've had a project on the go for a whole now and I fitted one side today, so now I know it fits although I've not started it yet and run it up as the paint needs to cure..
I'll go back to the start and run through with the progress shots.
This is the mould made from parts of a rover cover wood and car bog.... Lots of car bog!
You can't cast from an original cover as I shrinks so the mould has to be an even percentage bigger all round so it shrinks to the correct size.
This was the first attempt to cast but because of the thin wall thickness (you can see a hole in the inside wall where the indentation is)the foundry said it needed to be hotter and use nitrogen to get rid of the oxygen.
So the next time round was ok and the process documented.
More to follow.

As you can see from the thread cut quality of the casting is good, no air in the cast.
And they use a much smoother sand on the outside so cleanup is minimal
More to come
I've also made some 10mm rocker cover spacers for those fitting roller rockers, we have a set fitted on a griff here and are performing well, no leaks:-)
I'll post a photo later, I have the PDF with the laser cutters for these....
Ready for the engine enamel, I used por15 engine paint.
And finished,
Getting the filler neck off the old cover was a mission as it had been epoxy'd on but sanded and polished it finishes them off nicely...
Just got to fit the other one now. Adam Q any tips for easy removal of the throttle linkage and can the supercharger stay put?
Cheers
Adam

Yes the other side is a pain. You can undo the throttle body from the back of the supercharger in situ. Although one of the hex head bolts is hard to get at you don't have to undo all 4, you can swing it out of the way after removing three.
Cheers mateThought there had to be a trick...
So it's a dry joint then?

Thats the one!!!I have had interest in casting sets but I think it works out too expensive (if they are finished ready to fit), although less than a good original set going by what they have previously gone for on ebay.....the reason I did this apart from the challenge was because I wanted a set and couldn't afford it.
Materials, casting costs and postage I can do nothing about but the work involved in machining painting and polishing up the alloy bits to be honest would be better done by the enthusiast.....:-)
I'm happy (free of charge) to drill the large holes,tap them and the fixing holes as I have the jig.
I'd like to see them on cars, seems a shame not to make the most of this as they are now so rare.

That's who I've used as the P&P price surface mail 8-12 weeks which is £40 approx. double that for airmail.

Hi all,
Every where I look for a cheaper postage option ends up more expensive than Auspost :-(
$70 or £40 is the cheapest I can find single package 8-12 weeks.
Or a parcel 60cm x 50cm x50cm is about $300 but I'd probably get maybe 5 or more pairs in there
And thats 2-3 days.
I fitted the other rocker cover on last night bit of a pain on the sx but all good now.
Cheers
