Loads of WD40 has failed to free the roof frame - but this is all assessment stage anyway. The scuttle is going to need more than a battery box, but that should be straightforward enough.

Now Covid things seem to be easing off, going to find out if any local colleges offer welding/bodywork courses.

The bonnet’s wide arches are very interesting. They seem to have been let in by cutting the original arch back, slotting the wide arch in, then stitching and filling the three layers of inner tub, arch and wing.

What do the doors open and close like?

Fine, apart from the handle on the passenger side being disconnected.

I think the tub is sound enough, just rust from battery and brake fluid as you usually find. From memory sills and floor are good but I’ll check below the battery tray once the roof is off so it’s less claustrophobic.

Bookmarked. Love the look of this little Spit 6 - it always looked so forlorn sat in the FOD. Is she a runner? I'm assuming probably not... 😆

It was - but I haven’t tried it yet!

The fuel tank was taken out cleaned, slosh tank sealed and then it ran.

@Slowsilverwas never able to do a sub 10sec 1/4 mile!

Thanks for starting a thread on this as requested.

Wasn't quite as easy as it sounds. It had some sort of weird home-made immobiliser on it which I had to rip out and then rewire the standard ignition system. The distributor was full of what looked like grey candy floss so was cleaned out and the points were removed, cleaned and refitted. Then the plugs were taken out and cleaned and the compressions checked while they were out. All the cylinders were about 180psi, equating to about 12:1, which sounds quite high to me. Checked that there was a spark on each cylinder then refitted the plugs. Cleaned the filter in the fuel pump and hand-primed it with some fuel. Set the ignition timing to a nominal 10 degrees BTDC and cranked it over. No start but lots of spitting and coughing. Loosened the distributor and tried twiddling the timing randomly while cranking it over. Eventually it fired up so I adjusted the timing for the smoothest running and tightened it up. Rechecking the timing then showed it to be about 90 degrees before TDC, which seems way out. I rechecked the firing order and I am sure it was correct. However it now ran OK so was exercised up and down the track. Unfortunately it had no brakes and was eventually stopped by rolling it backwards into a conveniently-located Triumph Herald (sorry Chris & Claire). Broken light lens on the Herald and minor dent in rear panel of Sixfire which was soon remedied with a block of wood and a lump hammer (Copyright Slowsilver panel-beating services). Then it stopped running. No fuel in the pump so we assumed it had packed up. Checked the inlet and, despite having sloshed a fair amount of fuel in it initially, no fuel was coming in from the tank. Checked the tank and it was empty again. Sloshed in yet more petrol and off it went again. Judging by the compressions measured, where the timing ended up, the noise it made, the amount of fuel it used in about 5 minutes and the fact that it accelerated like a scalded cat I think the engine (which we think is, or was, a 2.5 litre from a TR6) is far from standard. It will be interesting to see how it goes once it has brakes and can be thrashed tested properly.

Thankyou @Slowsilverfor filling that bit in - and @Six-cylinder, eight years in the field might explain why it’s an antmobile! It always has ants running across it when I go in the garage.

Wonder what the details, suspension etc looked like eight years ago. There are still stickers on things like the springs.

Doubt much will be reported this week but on the plus side, the lower front valence is rust-free - it appears to be GRP! I didn’t notice that when loading. 

Which raises the question: pipedreams of carbon fibre be damned, GRP bonnets and bootlid skins? The only bootlid skin I’ve seen so far is £250, but given how simple the overall sheet is I suspect the rusty corner could be repaired?

Again, spitballing. Nothing even remotely concrete; idle thoughts to work out shapes of what can be done.

Odd Triumph never made a factory Spitfire 6.  They made the GT6 but not the open car. Y'd have thought there would have been a market. They made the Herald/Vitesse. Seemed a shame.

I suspect because it was developed backwards - Spitfire begat GT, GT underpowered, drop bigger engine in to make GT work - and by the time that’s done Triumph is part of a larger empire with cars that would be seriously undermined by a Spitfire 6 plus bad experiences/numbers with things like MG Cs.

If you have a rusty bootlid, could you use it to make a female mould. Then you could make as many bootlids as you wanted.

You can buy complete sets of panels and tub for Spitfires in GRP and eradicate all the ferrous parts in a single stroke!

I have never been keen on GRP panels because they never fit properly and we have just changed a front wing on the Allegro from GRP to a good used original. Also on the whole unless panels are destroyed I prefer a repaired original panel to even a steel aftermarket.

It's a Triumph, none of the panels fitted properly from the factory!
