    The Morris is a bit of a distraction but I am trying to maintain some progress on the Dennis. We had another day of driving it around as the weather was good and there was no salt on the roads. 311218trimmed.mp4 After running around for a while we emptied the petrol filter bowl into a jam jar. The one on the left is new clean petrol and on the right shows particulates and a little water. No stoppages today which is a definite improvement but I think I will continue to flush the contaminated fuel through a filter each week and burn all this brown fuel off before putting fresh fuel in. I have been making the covers for the door pockets. Starting with the leather off cuts from the seat cushions I used a cardboard template to mark out the leather and started to stitch the edges. After stitching the whole way around I treated them with some leather balm.

    Not strictly a vehicle, or even a vehicle part...but in absence of anywhere else I thought I would share the latest acquisition on HMVF - it may be of interest perhaps? Thanks to the generosity of a very good friend, I have acquired a vintage 8 cylinder radial engine that would have originally powered a torpedo. Its pretty much complete but a little scruffy. As just about every other British origin torpedo motor is a four cylinder radial arrangement, this eight cylinder version is - I suspect - a bit of a rare beast. It is most likely an experimental model and quite possibly originating from the Whitehead Torpedo factory in Weymouth. But as of now, its history and origins are unknown. One thing apparent is the the threads look like UNF and the nuts are nyloc variants, so the first obvious question is when was the nyloc nut invented? That would help with a date range, if nothing else. Will update the thread as restoration gets underway, but like most projects it won't be rushed. The intention is to make it a runner (heaven knows what fuel!) and possibly fit it into a Suzuki GS750 rolling chassis that might be available at some point.

    Happy New Year to all our readers, hope 2019 will be good to you. Time to catch up with the Christmas tankering. Brake linkage is all finished, cleaned, freed, repaired as necessary and then given the repaint treatment. Ready to fit back on when the time comes. Moved on to the spare wheel carrier bits that have been lounging behind the shed since the cab top moved out. Most of it started like this. Complete, just badly corroded and in need of cleaning and repainting. Several hours of wire brush in the grinder, then paint shop washing line and we get to this Brake drums got a coat of green at the same time. More bits ready to go back on. Quick question for those with significant others. Could you get away with putting truck parts on the posh oak dining table? Answer, only nice clean ones, and after asking very nicely. Cupola hip pads being retrimmed Had to borrow her sewing machine too! There may be a substantial price to be paid for this, later. Anyway, had some cloth left over from the seat recovering, so thought I'd have a go at retrimming the Hip Pads. Original ones looked like this, but were so rotten...…... They just fell apart like this. So, bit of guesswork with the calculations, bit of string as a compass to draw the curves, cut out and sew together. First attempt went into the bin, but a few adjustments and the mark 2 version looks quite tidy. First one off the press, and 2 more to do. I think they'll do nicely

    I am glad to report that after a frustrating day chasing different problems, the old girl coughed back into life at 7:30pm. She sounds lovely and quite and the oil pressure is perfect. Jon

    December 31st On the last day of the year, I went to give the Dodge one last check over before the winter weather really sets in. I added another gallon of fuel as the tank was getting low, and gave the engine a good warm through. Clutch and brakes were exercised, lights checked and the truck moved in the container to avoid tyre flat spots. After it was nicely warmed through, the engine was shut down and the battery was removed. I brought it home to add some acid tablets and give it periodic charging over the Winter until things warm up again in the Spring.

    So here is the truck with the wrong rear body (but I like it) as I can carry my 45 M29c weasel on the back.

    Oh yes, between Xmas and New Year another parcel arrived from the UK. This one had been some time in the planning and has most of the necessary bits to finally get the brakes set up and also the wiring sorted. Very pleased.

    Thanks for your interest in this blog. We're still busy restoring Michigan, but a lack of time has caused me to somewhat forget about this blog. we're currently working on the woodwork of the rear body.

    I look forward, with excited anticipation to the Thornycroft updates, and now that’s coming to a successful completion I would like to thank ‘Team Gosling’ for their tireless dedication and the many hours spent in the shed, and would like to wish you every success with the Peerless restorations. Never let it be said that Team Gosling allow the grass to grow under their feet!

    Yes, in a few minutes it was over. Amazing level of engineering for such a short time. We do know very torpedo built at Whiteheads was fired at least 4 times before being shipped to the customer, just to make sure it would function as intended. We have found a few in Weymouth Bay that went missing. All of them had lead segments replicating the weight of the warhead. That one is a real gem, and so far the only other 8-cylinder example I can find. Because of where it came from (Weymouth) we are pretty sure it came from the Whitehead Torpedo Works at Wyke. Whitehead were taken over by Vickers Armstrong and as far as I can tell work on an 8-cylinder engine started in 1938 and continued after the war. So current thinking is UK/experimental/test & development unit. I had not considered a captured/foreign unit, and is possible. Nor had I considered the nylocs being a recent(ash) edition. Some of the studs are not long enough to fully engage with the nylon insert, so thats a possibility too. There are a few documents to look up in the National Archives, so a trip is planned soon. And thanks for a clear and simple description of how and why it works the way it does Watercart - that was a big help in understanding some features I was scratching my head at. Nice find with the Japanese motor too - glad its been saved.

    amazing that this almost forgotten engine technology has been around for over a hundred years and never been developed. Think of the bhp potential from such a compact engine! Incredible to think something this advanced is built a a single use engine, made to last just a few seconds!

    A very interesting engine. I wonder who made it? I had some dealings with Commonwealth service torpedoes pre 1990, but have never seen an 8 cylinder engine like Simon's. If it was made in the UK, I would be reasonably certain that it was not produced in any quantity. Another angle is that it may have been an example of a continental engine (1900-45?) recovered for tech intel purposes? Re nyloc nuts, can you discount that someone has not had a go at restoring it more recently? The engine sold by Prestons is a 4 cylinder radial Brotherhood burner cycle engine that went into service in the 21 inch Mk.8 (submarine) and Mk.9 (surface launched) torpedoes. The Prestons one in particular looks like a WW2 produced type that would have been in service until the late 1980s. Recently I had the job of sectioning a whole Mk.8 torpedo for a museum and read the manual that came with it. Some interesting specs: (1). The fuel is listed as "shale oil".(2) It carries about 250 pounds of compressed air at 3000 psi (3) Due to this air pressure and volume, the throttling effect would tend to ice up everything (like how a spray can goes cold when you hold the nozzle down for a long time). (4) They get around this by admitting a small quantity of burning fuel to the air to heat it up before it reaches the engine. (5) The preheated air and cylinder injected fuel then operates as a diesel exhausting into the crankcase and out the propeller shaft. (6) The pre-burn is started by three blank cartridges that are fired on launch. (7) If the ignition fails, the torpedo can still do about 22 knots just on air pressure for a few hundred yards. When the navy tested the engines on a dynomometer, they would routinely produce about 550 horsepower. Not bad for a tiny radial engine designed in 1926. All that said, the salient point is that you need about 3000 psi air boost to get that performance, so not especially convenient for a motorbike, etc. My reference to tech intel is base on a discovery made in Sydney a couple of years ago. In the mangrove swamps near an ex-ordnance depot, a large complex bronze casting was pulled out of the mud. No one had any idea what it was, but it was kept due to being old and mysterious. It turns out to be a Whitehead designed long stroke 2 cylinder engine from a Japanese submarine torpedo. This was a 21 inch type, but the fabled "Long Lance" Type 93 24 inch torpedo used the same design. BTW, while torpedo engines may seem a bit niche, torpedo gyros have been keenly collected for many years. They are amazing bits of precision kit and span about 120 years - from clockwork, compressed air to electrical methods of spinning them up. The Mk.8 torpedo uses a quick blast of the 3000 psi air supply to bring the rotor from standstill to about 30,000 rpm in a fraction of a second.

    Yes, compressed air, burner cycle with or without enriched O2,, HTP (High Test Peroxide) and electric are all examples of fuel used. I did have an electric Mk44 air dropped torpedo for a while and connected the motor up to a car battery to see if it was still viable. The contra rotating props worked a treat. But the missus drew the line at an intact, complete and functioning (less the warhead and original battery) torpedo in the garage, so it was donated to the local Sea Cadets who thought all their Christmas and birthdays had arrived at once, so it went to a good home.

    Dear All, Even the E5 bio petrol caused serious problems with the REME museum's Conqueror ARV. I made up a fuel manifold to supply each of the 24 electronic fuel injectors. I used 15mm copper pipe and soft soldered on a compression fitting to supply each injector. In terms of fuel leaks it worked fine for some time. Then suddenly it was spewing petrol everywhere! The bio fuel had attacked the soft soldered joints. Even though the joints had plenty of cross sectional area of solder, they still failed. The new system that I have made has no soft soldered joints. This suggests that many vehicles will need a completely new fuel system with no soft soldered joints anywhere. I will shortly be posting tales of woe about Meteor tank engines and petrol contamination of the sump and the possible effect on the white metal of the crankshaft bearings. I suspect that the reason why Government has not moved faster to E10 is more to do with issues concerning the economics of supply and possible adverse effects there rather than the effect on old vehicles. I think that E10 will be ubiquitous in due course whatever problems it causes to older vehicles. The problems for our vehicles are manageable provided one is not too worries about originality. The real problems will be for those with later vehicles (especially cars) with sophisticated fuel systems which are not tolerant of E10. I expect that the response from classic car enthusiasts will reflect this. John
