Does Jaguar still have the press tools for the XJS?

Good question, OB. I remember about 10 years ago or so, the JEC had a bit about this in their mag. The tools did exist then, or most of them, and they were stacked in a some sort of west midlands outdoor dump getting rusty along with all sorts of other heavy bits of old steel tooling and stuff. There was talk of their being used to make certain parts, and for all I know some were. There was also, not quite so long ago, a letter to the JEC mag from one of the really expert and really expensive bodywork guys, based in Worksop, Alan somebody now retired, complaining that the parts being supplied by JCP were not sufficiently accurately pressed to be fitted without extensive fettling. So I guess some parts were being turned out from the old tooling.
Truly and honestly though, it is commercial suicide to try to utilise old tooling unless you have a really substantial demand and also can sell them for seriously high prices (E type panels and bonnets anyone?). Together with which, while there remains a substantial supply of scrapped/could be scrapped XJSs, there is no real shortage of panels or parts. Added to which, press tooling life is not indefinite and probably most of the actual presses the old tooling fitted are themselves obsolete. As soon as tooling edge definition goes, it is amazing how sensitive the human eye is to quarter millimetre differences. Half a millimetre edge loss of definition on (eg) a pre-facelift rear threequarter panel waistline crease is really noticeable and any more looks awful.
But you have an important point, as always. It will be rust that does for the XJS, not lack of mechanical parts. Those of us with rust free cars will watch from up there, or down there more likely, as our beneficiaries reap E Type money!

Interesting Stuff but I'd really love an XJS with an Aluminium Body, so that will be on my Wish list, if I happen to win the Lottery on Roll over Week.

OB,
As Greg has mentioned, we did look at this issue some years ago. I suspect that an XJS bodyshell will never be produced again for a number of reasons:
- The tooling that exists (or used to exist!) is very old. Alan Proctor who was the JEC bodywork technical adviser for XJSs was having many problems with the remaining panels even 10 years ago. I don't think the old tooling (if it still exists) would be capable of pressing panels any more.
- There is a huge difference between the pre-facelift and facelift panels. Even the facelift panels were changed over the years. There are 3 or 4 versions of the facelift front wings as an example. So, deciding exactly which bodyshell to produce means there is a already a very limited audience.
- JLR just doesn't have the resources (or possibly inclination) to invest in what would be a huge project.
So, keep on spraying the wax each year!
Paul

Cheers, Spraying the Wax it is then and also such a shame that no one seems to have had the foresight to save the old tooling, when they ceased production.

£250 ten years ago? This shell was £1750 2 years ago. So maybe shells are better investments than complete XJSs!!
Remember that re-shelling an XJS is a phenomenal amount of work. If the car is that bad to start with it will also need a huge number of other unobtainable parts. I don't anyone who has re-shelled an XJS which is probably why this shell has been for sale for years.
IMO, it will end up being sold very cheaply to someone who needs a few body parts and will end up being cut up. Just MO.

To be fair, Paul, if you have the original car with all, or most, of the bits on it, removing them all and putting them into a new shell is a viable option - from the do-ability point of view. BB pretty much did this with his car I seem to recall. I speak as one who removed everything from his shell, and I mean everything, fixed the shell and rustproofed it, then put everything back in. By far the worst bit was taking all the old bits out of the shell. Replacing it all, with a good smattering of new parts as required, was a breeze compared with the dismantling, positively enjoyable, and in reality took very little time, as in total about three weeks once everything was there, clean and ready.

Doesn't mean it will be sold for that money.
Stored outside now in primer only with some surface rust visible and possibly more hidden, don't think I would go for it even if funds and space permitted.
I wonder with modern technology about possibility of digitally scanning body panels for reproduction in aluminum, might there be a market for that or am I dreaming!

You are probably right but if I win the Lottery (Tonight) then all bets are off.

Agree with that Paul, just because they're asking for £4,400 (approximately US$6400 or Aus $8700

You could in theory put ally outer panels on an XJS (boot, bonnet, wings front and rear, doors). It would be a problem keeping them rigid in the medium term though, as the those lovely flatish lengths of wing would need considerable bracing from underneath. Take the bonnet, even in steel it has very substantial inner bracing to keep it in shape. You could even find the weight saving was practically zero. Once in the late 1950s Maserati (I think it was, but it might have been another firm) made an aluminium tubed spaceframe for one of their racers. By the time they had it sufficiently stiff, it actually weighed more than the steel tubed item it was to replace!
The real weight saving in the modern Jaguar cars is from the chassis being in ally. And this needs seriously careful design and build, well beyond all but major manufacturing and CAD/CAM resources. So redoing the actual load-bearing monocoque in ally would be a non starter.
E types, D types and so on have mainly curved outer panels, and these are much easier to make reasonably rigid in ally than the XJS would be.
Having said all that, Ronbros has removed a huge amount of weight from his convertible using essentially straightforward means. Also, if weight saving really is a priority, then the aircon can go - 100% of it, the electric seats and anything like that too, the hood on a convertible (or at least the motors that drive it), chuck the bumpers, use thinner glass, remove the window motors, remove everything non essential in the engine bay, swap out old fashioned soundproofing for lightweight modern stuff, use an ally rad, remove the spare wheel, and pretty soon you have got the car down from (for a pre-facelift coupe) 1750 kg to 1400 or less. As the Great Colin Chapman said: "Remove weight and add lightness".
Even, buy that shell and have it acid dipped to remove 15% of the metal throughout - it worked for TWR on the ETCC cars!
