    WW1 Thornycroft restoration

    Take a deep breath, bite the bullet and do it properly! Grind off the rivets, unsolder, clean it out and put everything back again as it should be! In you heart you know it's the only thing to do.

    Ben, is there a reason for the expanded aluminium mesh behind the radiator core? The sign writing looks super. Have you had an extended drive of it to see how the engine pulls?

    Not ever having done this, how long do you leave the water in for before you think it is safe to attack the tank? A day, two days? No matter how hard you try to clean parts in the fuel supply chain they always seem to smell of petrol. How does smell equate to petrol vapour? Can you purge a tank with Argon and then go for it straight away? How about using a 'wet and dry' vacuum cleaner to suck the vapour out (with the petrol tap open) or will the cleaner go bang instead?

    Lucas had a standard universal bracket for bulb horns of this type. Unfortunately this picture does not show it too well, but the brass stalk has an adjustable 2 axis swivel clamp. On the end of the stalk there is always a Lucas King of the Road badge. The horn in the above picture does not appear make use of the mounting boss which is rivetted to the horn body and as such is non-standard..........and just looking on ebay there is a perfect example of the standard bracket! (Should we allow Steve to make the split clamps from brass bar or should we insist he forms them from sheet metal?).

    Does anyone have any further details on this? Barry.

    What fantastic tyres!!! They look as if they have been properly molded in steel or aluminium dies. Can you tell me more about the process and how you persuaded the company to make you just a few? I am assuming that you didn't have hundreds made to spread the cost? Do you know if they are willing to repeat the process with different molds? Dare I ask to the nearest $10,000 how much they were? The last tyre in your top picture (the one propped up against the pile of modern tyres ) seems to have a join mark. What is this? I find it hard to imagine why there has not been a greater response in admiration for you persevering and getting your lorry such an amazing set of tyres. Best wishes, Barry from the North East of England.

    Mammoth , Stick with the Mercedes engine, it will be far easier for you.........and let me have this Dennis engine!🤗🤗🤗 What a find! I wonder whether it is just a teaser or whether it could change hands? Best wishes, Barry.

    Andy, I think it looks like a soldered up brass header tank but built as a replica of a cast aluminium top tank. Very unusual and unique! Barry.

    Steven, This is my 1913 Dennis. The points of interest is that it does not use the White and Poppe engine with the four separate cylinders but a two block engine with thermo-syphon cooling. The fire fighting pump is not the larger size found on the later 'N' types but a smaller Gwynne. The standard piston primer is contained in the rear locker, but it is just single unit and not paired up as on the 'N' Types. The radiator cap mascot has no relevance to the discussion, but what a super mascot for a Dennis! (The brochure extract is my actual machine as it was originally supplied to the John Dickinson works fire brigade. You will notice that there has been a change of radiator and wheels). Barry.

    Ben, where did this bit of red come from? The belt pulleys seem quite some way out on an unsupported shaft. For a moment I thought that you might have mounted an auxiliary bearing on the fan bracket to give extra support. When you tensioned the belts did the pulley shaft flex at all? Are we going to see pictures here of the adventure that the lorry had a few days ago! Barry.

    Ed, I would just pull off each plug cap in turn and listen for a change in engine note to see if I was missing on a cylinder. Is a 'Cylinder balance Power Check' anything more sophisticated? On my early Dennis's charging a cylinder beforehand and then returning up to a couple of hours later is like you say a real 'party piece'. The Dennis's have trembler coils so we have plenty of sparks to set alight the remaining mixture. Barry.

    This was in the era when the F1 rules permitted either 3 litre normally aspirated engines or 1.5 litre turbo engines. The turbo engines ran with tremendous boost so although they started off with only 500 BHP by the end of the development they were producing close to 900BHP. The BMW engine programme was run on a shoestring with them making do with whatever they had available. Stress relieved old blocks were therefore essential to the campaign. However, we are talking about a Thornycroft here, so hone out the bores, skim the pistons, perhaps increase the ring gaps too and enjoy happy motoring with 50 trouble free horses.

    Yes, later models were not fitted with the trembler coil. This is how it can be started without B.E.N. https://www.youtube.com/watch?v=ivN1FNsrCsI

    I don't know if I know how to do that........ Here is a video of another starting system called B.E.N. https://youtu.be/KwZL-JDnBuY

    I was intrigued by the last post from Ed. I have a 1913 Merryweather fire engine where starting is quite difficult, due to the engine size and compression. In the U.K. starter/generators are called DynaStarts. The advantage being is that the belt drive is permanently engaged and once you have used the 'Start' part of the unit the 'Dyna' part charges your battery. For the Thorny and my size of engine (10 litres) you need quite a big DynaStart. There is a man on ebay specialising in Dynastarters for our type of application and typically sells 10 sets a year. The best belt to use is a 'Polyvee' belt, which you see wrapped around serpentine like on all the Front End Auxiliary Drives on large car engines. These are like 4 or more tiny vee belts all joined together side by side. A pulley ratio of 6:1 will give a torque of 60 ft lbs at the crank. How does that compare with Steve giving the hand crank a good swing? Probably about the same? Anyway, I think I am going to give it a try. The seller will accept everything back if it doesn't work and give an 80% refund which seems quite fair. The great advantage of this type of unit is that you don't have to fit a starter gear ring to the flywheel or do any machining at all. With luck the DynaStarter can just be clamped onto chassis rails without any hole drilling, so the system can be removed without leaving any traces behind if you wish to go back to complete originality.
