    Thanks for that Hedd. I will think on that one. In the mean time, I have heard back from the Slosh people. Unfortunately, it is not possible to re-coat the inside of the tank as the new coat will react with the first and won't seal. They have suggested using an epoxy putty on the outside but that will leave an unsightly lump which I don't want. Can anyone offer any more thoughts please? Steve

    I don't think it really needs a patch on the inside as the surface is so much better. I only need to block the hole. I could nut it on the inside if it does work loose. Not come across 'Tigerseal' before. I shall Google it! Steve

    Well, that one has prompted some discussion! As it is non-structural and not pressurized, I think that four screws will be enough. I can always add more if necessary. With only four, however, I won't be able to get a good pressure on a gasket, rubber or otherwise so I think I will go for the liquid solution. Silicone seems pretty good but I will have to clean the surface fairly well. I shall use cellulose thinners to get a good clean ring around the hole. Oil in the hole won't matter too much as I am not trying to fill it. As long as I can get a continuous ring around the hole, I am sure it will be fine. Many thanks for all of your thoughts! Steve

    I have managed to do a bit today and have fitted the patch to the sump. It started out as a bit of 20swg copper from the drawer suitably annealed. Then a bit of tapping around using the bossing mallet and a panel beaters hammer, annealing between each go. I annealed it about twelve times altogether. I drilled and tapped the casting for 2BA. The casting is horrible in this area, full of porosity and only 1/8" thick. Then just screwed it down. I shall seal it with modern silicone instant gasket which I think is forgivable in this case but that will have to wait until I get down to Devon again. Wing mirrors next. It never had any but I have tried driving without and it is scary as hell! They will go on the cab frame under the wing nuts. Steve

    Well, we went to Beaulieu Autojumble last weekend but no great 'finds' unfortunately. We did see lots of friends though and a number from this forum which was wonderful although it is most disconcerting to be recognised! We also met an enthusiast for 'Radmill' lighting equipment. He has a significant collection of them but surprisingly, no gas generator so he was very interested in ours. It seems that ours is a lot rarer than we thought which is interesting to hear although somewhat unfortunate as we want another three! It looks like we will have to make them. Oh well. We are still making some progress. I started on the headboard in Father's car-port before bringing it back here to Leicester for completion. This is now done and it is ready for the paint shop. Adrian has very kindly given the sump a light sand blasting so that we can see what we have. It appears to be a casting fault as there are several cold-shuts in the area and possibly a crack along the inside. I made the fatal mistake of poking it with a small screwdriver and going right through! I have some repair paste but think that a patch might make an appropriate period fix instead. I shall try that solution tomorrow. On the subject of fuel tank sealant, I have written to the suppliers to see if a second coat would be an acceptable solution. We will have to see what they say.

    Yes, a bigger garage would be a great asset but we will have to live with what we have. Actually, more floor area would be useful for the next project! In the meantime, we are trying to push the Thorny over the finishing line but it is not giving in without a fight. We took the sump off on Monday. We expected to undo the bolts and just drop it but famous last words. It stuck to the gasket and just would not shift. We had to strip down the oil pump and front of the engine in order to get at the joint. Lots of knocking and pulling from awkward angles went on but it eventually let go when Father held a jemmy inside against the underside of the crank case and I hammered a chisel into the end joint. It took us three hours! Dad wiped out the sludge which had accumulated in a surprisingly short time. I now have it with me ready to fix the leak. I think it will be a Dremel and filler job. We shall see. Steve :)

    Well, we had a nice day at The Great Dorset on Friday and saw a lot of friends and old lorries. We have had a lot of opportunity to discuss the fuel tank as well. We have reached the conclusion that the lowest risk approach would simply be to Slosh it again as Barney has suggested. It is a bit pricey but offers the remotest chance of blowing ourselves up so we have, today, drained the tank down completely, removed it form the lorry and left it on end with the cap off to dry out. I'll order some more Slosh shortly. In the meantime, we have been back working on the lorry. We have put up the hood frames and trimmed the longitudinals to length before drilling the ends and fitting them. Next job is to make the wooden headboard up and then to remove the sump for investigation. Steve

    Yes, and only 36 hp to haul it about! They didn't seem to consider weight very much! Steve

    I had a nice weekend making up more bits. This time, the shovel and pick brackets. I am fortunate to have the original Dennis works drawing for these but it appears that they are a Govenment standard so the Thorny will have the same type. First challenge was to find some suitable timber. Fortunately, I had a pice of school woodwork bench in stock which is Beech and hard as hell! I manually planed this to shape. The second one was cut from a piece of Herbert Machine Tools workbench which I also had in stock as being too nice to scrap. I did have to dodge the bolt holes, however. I had nothing in stock for the last one so I laminated it and then cut it to size. I did the chamfers with Grandfather's spoke shave which he used to build frigates at Charles Hill's Shipyard during the second war. I do love using his tools. Then onto the steelwork which I bent using the press. It was bright steel strip so I had to anneal it frst to prevent it from cracking. The shovel handle bracket was a bit tricky. It is supposed to be riveted together but I couldn't see how I could get a snap in there or bend it afterwards so I bottled and used my favourite silver solder. The rivets are supposed to be countersunk so the bracket looks no different from the drawing Complete and ready for the paintshop. Headboard and rear lamp bracket next. Steve

    Thanks, Chaps for all of the advice. At least I have recognised the potential hazard before finding out the hard way! Current thinking is to fill to the brim completely with water to push all of the fumes out. Then I want to unsolder just the outer skin which, with a bit of care, I should be able to do without getting the inner one too hot. I shall drill a couple of holes in it so I can drain the petrol in that space and tap the plate so I can put a screw in it to start lifting it up. It is a real pain living 200 miles from the project as everything has to be planned in detail to make use of the short timescale. Oh well. Some things still going on slowly. When we were down last week, Tim spent an age touching up bolt heads. This is a very tedious job but has done wonders for the lorry's appearance. We have also carried on with the hood bows. I started off by bending them to shape using an anvil tool that I made up. Dad had cut the angles perfectly so the quadrants just dropped in and were ready to weld. In the mean time, I riveted the lap strip onto the centre flat bow. And then drilled the bottom edges where they bolt onto the extension pieces left by Father. The longitudinal bar brackets, I had already bent so these were riveted as well. Centre bow ready for paint! We riveted the joiner plates onto the end bows. Then a trial fit to get the bolt hole positions. Once welded by a pal (Thanks John), the longit brackets were riveted in as well. Dressed off ready for paint. Just the top-coats remain and then we can tick another job off. Steve

    Many thanks for all of your comments chaps. My experience of welding old aluminium has been of 100% failure. There is something in it which just won't weld no matter what kit you have so I feel more inclined towards the filler route at the moment. However, we had a brainstorm this afternoon and had a look in the spares collection and came up with this. It is an earlier pattern sump which doesn't have the holes drilled for the oil pump but the boss for it is there. Dad is going to clean it up and see if it looks promising. Fitting a good one might be the easiest way out of all! To use it, we will have to remove the old sump anyway so that will be an opportunity to have a good look at it. Steve

    Ah, but you know how much I love my silver solder! Seriously though, a good silver-soldered joint is as strong as a modest grade of steel so I am quite confident that this will survive. No doubt time will tell! Cheers! Steve

    We have had a nice day again and have fitted all of the rope hooks. Definitely a two-man job to avoid climbing in and out of the back all the time. Another job ticked off! I also took the opportunity to crawl underneath and have a look at the sump. Once I had wiped the oil away, it became obvious that some sort of filler had been used to fill some porosity in the casting. It looks like soft solder. The oil is leaking and steadily dripping from the joint line between the two metals. The question now is what to do about it. I am wondering if I could cut some of it out with the Dremel and fill the resulting groove with Plastic Padding or even a silicone gasket material. Any suggestions please chaps? Steve

    We had a nice day out yesterday at the Bovington Amiens Commemoration Day with all the lorries you can see above and some more. No doubt Tim will post a report shortly. In the meantime, we now have a horn! Thanks to Barry's photos above, I have made up some representative bits. These were done in Leicester and I have since cleaned them up with a file and broken all of the corners. Then it was on to the base which is bolted to the curved top edge of the dash plate. My usual favourite, silver-solder! Getting closer to being legal. We only need a rear lamp bracket to complete the requirements. Hood frames are in the plan for today. Steve
