    I know Joe quite well but I suspect these would be very expensive! The SU catalogue has the HV3 with the vertical configuration, I guess they made both.

      A bit more "Scan n Cut" action today. Mr Fuggle needs an exhaust flange gasket for the truck and no-one seems to have them.
      Back to Brother's website and their CanvasWorkspace software and after trying to remember school geometry, I managed to get a decent design. The cardboard sample fits really well so I will now contact the local water jetting company and see how much it would be to cut some 1mm (ish) copper (or 0.043") for me.
      These will fit Talbot AG 14/45s either with standard exhausts or with the Rawlings conversion. Would anyone else be interested in one as I'm thinking of having a few made?
      I'm not sure if they'll fit the AD as the part number is different. The AG 14/45 part number is 308020.

        A final push on the Holiday Fettling of Mr. Fuggle's truck has 2020 starting the way 2019 left off: Two steps forward; one step back!

        After procrastinating for too long, I decided that there weren't any more excuses for putting the head back on. I had re-routed the fuel line I fitted when I put it back on the road to the other side of the engine to keep the left hand side as clean as it is supposed to be; I had made and fitted the SU adapter and even prepared for having flange gaskets made for the exhaust. Today was the day!
        I cleaned the gasket with scotchbrite to remove the soot left by the heat treatment and carefully applied Wellseal to the block. Then I noticed that the large hole for the big head stud was in the wrong place on the gasket. These Talbots have one of the head studs much larger than the other to carry oil up to the head. This is placed one stud back from the middle. The gasket had it in the middle. Odd. Never mind, I opened the hole out with a de-burring tool and the stud passed through. Happy with this, I applied Wellseal to the gasket and waited 15 minutes for it to get really sticky and then placed the gasket on the top of the block.

        Despite the gasket being bought as a pair in November and having the same part number written on it, it isn't the right size! It's over a quarter of an inch longer than the block! The other one of the NOS pair is fine, as is a newer replacement I bought two years ago. The newer one was heat treated at the same time but still fits OK.

        Is it possible that the older solid copper gasket expanded in the heat treatment process while the more recent pattern one, treated at the same time didn't? It can only really be the heat treatment process because originally they were made by stamping them out one end at a time, the difference between the two is like one's been photocopied at 105% so I can't think how this could've happened during manufacture!
        Anyway, luckily I had the newer replacement, annealed and ready to go so the head is now on!

        Happy 2020!

          After some excellent CAD action from Jason Reece (Thanks Jason!) and a bit of water jetting I have now a collection of Talbot 14/45 exhaust flange gaskets in 1mm Copper. I will have a go at annealing one and fitting it to Mr. Fuggle's truck at the weekend.

            Well, another step backwards with the Fuggle truck.

            Mr Fuggle decided to fill the gearbox and engine with oil. Since the gearbox is connected to the engine with a balance pipe and the lid was off the gearbox, 4 litres of oil went in the gearbox (not knowing its capacity). This then drained in to the engine to the proper level in the gearbox. The engine takes 9 litres, apparently, so over 6 litres down and suddenly it looked like the Torrey Canyon had sailed past. I had left the bung out of the side of the sump which you remove to set the pressure relief valve. This shouldn't have happened - except that the gearbox only takes one litre so 3 litres were already in the engine when I poured in another 6 or so and the level reached heights that it was never designed for and leaked out of the bung.
            A litre of oil was scraped off the floor and a ton of cat litter called in to action.
            With all the oil in, it seemed that the gearbox had a leak. Maybe it was because it was over-filled? All the oil was drained out of the gearbox and it was left for a couple of days. The oil that was drained out was then put back but the leak reappeared. Bugger!
            The backplate of the gearbox was sealed (so I thought) with RTV when I rebuilt it but that obviously wasn't sealing. So, the rear axle was removed again and the torque tube pulled off the back of the gearbox and the backplate removed.
            Taking no chances (and not wanting to remove the axle and torque tube for a third time) the Brother Scan n Cut was again pressed in to service and after a couple of hours (!), I have a backplate gasket and one for the torque tube. There was never a gasket on the original scheme but, as the gasket material is only 0.25mm thick, I don't think that two layers of that will cause too many problems with the geometry of the torque tube.
            Maybe these will stop the leaks?

              A few steps forward on Mr. Fuggle's truck this weekend, the pushrods have arrived (well, after I had extricated them from the delivery office in the town where I used to live!)!

              I had the ends carefully lapped to give them a perfect 2.5mm radius and finally got the valve gear installed.

              The tappets are now set with initial gaps; the ignition is timed; the points gaps are set; the twin points are synchronised; a NOS condenser is fitted; the carburetter is on; the choke linkage is sorted; the fuel lines are installed; there's oil in it; the gearbox lid is on and felt oiler installed; it's on its wheels; the original exhaust is on and the battery is charged. There are fewer and fewer excuses not to get it started except it's run out of fuel!
              I reckon I just need to put some fuel in it, some spark plugs, some water in the radiator and hook up the throttle linkage and it'll be time to see if the hard work has paid off.
