This is great engineering to me. . . .. grinder, welder and a can do attitude, top marks
Don't forget the big hammer!
Here is the picture of the gearlever in approx position

- a frame/gearbox cover will provide the fixing points.
And here is where the fuel tank will sit.

When I revise the rear framework, it will be lower.

Unfortunately things have conspired to prevent more work on the BGT over the past few days so no fire up by Christmas.:sniff:....but possibly this year??
Anyway "Happy Christmas" to readers of this thread :wave:

Thanks ATE
Unfortunately no further progress - and work is shut until the 4th, so I reflected on the progress (or lack of?) and in fact there have been quite a few aspects which are now sorted and so 2016 should be the year when it all comes together.

I was able to use the welder today and so worked on the Drivers side exhaust - much cutting



................and welding



.......and it ends up looking like this.




Not as pretty as some - but it should be a lot more effective than the old cast iron headers!

Another job done, as I have welded the lower radiator support brackets to the front chassis legs. With the radiator in position, I then tried the fan shroud, which has a small electric fan and space for another larger fan.

FP, you deserve the 2015-2016 MG Madman Award for this project. Completely crazy and will go like a dingbat. Will the car be used for general road use or for the strip?

I have told the DVLA about the BGT reg and changes but they weren't really interested until it is complete. However it is really for the odd RWYB and possible shows/garage candy so a trailer queen it may be if I cannot get some form of registration.

Cracking on with the welder today. the drivers side floor pan cut, bent and welded in place.


Then most of the passenger floor.



Then the bracket to attach the handbrake in place.



and finally two supports for the gear lever and gearbox cover plate.

The handbrake lever has been fitted together with its cable (which is too long but a loop works!)


I've also been sorting out the brace bar that goes across the roll cage behind the dashboard - there is still space for it and it can tie in to the other dashboard brace - providing a mount for the top of the steering column.



Other work has been on the carbs to get a possible operating system by linking the throttle butterfly bars. It is possible to buy a system with two operating bars alongside the cam covers - but £330 plus VAT is not for me and I want a simple discrete system.

Well I have been modifying the Weber throttle linkages by welding tabs etc on, and now, the three carbs on each side are linked - so I just need to run dual throttle cables from the pedal ( to be done) to the middle of carbs two and three.


I have also made a start on the front chassis fixing point for the trailing arm link to the rear lower suspension arm. The tube will be sleeved to match the conical shape of the rubber bush centre. The rubber provides the compliance for the geometric errors (this is the standard XJ-S set up.)

I am still thinking about the trailing arms.
However the water outlet housing has been welded.



And I have been sorting out the illumination of the dashboard?????? Well the XJ-S had a rather nifty bit of fibre opticary for that job - so I've just got to use that!!

I have stripped the fibre optics out and the are 9 fibres connected to the source. Another surprise was that there are three colours! White, Red and a pale yellow. As the source is a filament bulb they must use coloured fibres. I have also put all the thrust washers onto the lower wishbones and bolted up the lower plate so the rear cage is now finished.

I was hoping to fire up then realised that it would be best if I had an oil filter in place........ I remembered that I need a blanking can as I bought a remote filter, then, when I put the newly welded water outlet in place, it points straight at the oil cooler pipework........So I am having a rethink about the oil system - do I need an oil cooler anyway? Where to put the remote filter?

Phil, the V12's don't necessarily run hot...but there is limited air flow within a 'B, so it would be worth installing a sensible sized 13 row cooler. Re' the remote filter...could you not install the remote similar to a V8, near the front of the car...it would also make oil filter changes much easier. A+

Thanks V8250 As the car will not be cruising down a hot Autoroute anytime soon I think the oil cooler is unnecessary. The big hole in the bonnet will aid airflow through the radiator.....
Some more welding done today. The brace bar across the front legs of the roll cage has been put in place and it has been tied in to the bell housing frame to get a good support for the top of the steering column.

I also put in the rubber bushed trailing arms - I valued the input from various sources re the need for the arms but, in the end, I thought it looked better and it will, very slightly, reduce the loading on the lower "dogbone" arm. I have checked the suspension movement and the compliance in the bushes allows full movement.


I then attacked the oil filter!



When the two parts are brazed together it makes a short filter substitute and the oil cooler pipes will be shortened to feed the remote oil filter which will fit on the block behind the exhaust manifold.

Big Thanks to Guy (Bigyellataxi) - I now have the pipework to attach the remote filter to the oil circuit. I will need to make a bracket to support the filter on the engine block.

Here you go - the oil pipes in place but a fixing bracket for the remote filter needs to be made


And I am making a start on the electrics using bits from the XJ-S loom to the instruments.

A bit of a change as I wanted to trty out a slightly different "Look" So out with the Satin Black spray cans..................





Then a bit more elbow grease on the rear hubs
