Thank you. I was feeling a little overwhelmed by an old single cylinder motorcycle engine I’m restoring. You have put my issues into perspective. Best of luck.

It is actually a lovely piece of Engineering. I certainly wouldn't like to tackle it myself but I can appreciate what it is. Truly awesome.

Its great that you are bringing this old girl back to life. Its sad to see them bent up and gathering dust. I'm sure the brave lads who flew with it would appreciate your efforts. I did my apprenticeship with Paxman during the 1970's so i've always loved the V engine.

[@noonehere1793]

Being a pilot and familiar with the merlin i think that your engine was in a controlled crash rather than an uncontrolled crash simply due to the lack of structural damage. Well done find and rebuild!

[@jesuschrist2284]

You sure its not a tank engine?

[@PatGill-tu6oq]

Tank engines do not have a supercharger and I believe the crankshaft is different. @@jesuschrist2284

[@PurityVendetta]

I enjoyed your intro video immensely, thank you. I understand this kind of engineering given the I work restoring vintage and classic motorcycles. I found the condition and preservation of the engine remarkable! The college I attended as a 17 year old had a cut away Merlin, supercharger and reduction gear assembly in the foyer of the engineering block. The collage is long gone but the cutaway exhibits are on display in Stoke-on-Trent museum and art gallery as part of the Spitfire exhibit. As a young person I found them fascinating. I admit to being slightly envious of your project, I'd love to work on something so fascinating.

[@robleary3353]

Love seeing old bits of kit bought back to life (especially a Merlin). Great job!. Can't wait for future updates. Nuff said 🙂

[@urabampot]

My Grandfather John Kinsella was a draftsman/machinist and then final inspector for RR all during ww2 in Glasgow, building and working on all makes of aircraft engines... So he probably built that engine or worked on it, or inspected it... blew my mind when i saw this... amazing!!... if you can find out if he did by the serial numbers, id love to know for sure... RIP John!! (*subscribed)

[@shug831]

I served my apprenticeship at Hillington, Glasgow back in 1980's. At the rear of the training centre there was an stripping/overhaul section for senior apprentices that stripped Merlin and Griffon engines. I remember they got in a Merlin engine from a crashed aircraft, that had been in a bog for many years. Once stripped, the only component requiring replacement was the crankshaft as it was twisted and that was replaced out of stock parts in East Kilbride! The used pistons made excellent ashtrays mounted on turned wooden bases for various Top Brass in RR. 😉

[@patrickradcliffe3837]

I have question about the piston rods. Does the piston rod that runs in-between the split rod ride on the same bearing? I see the split rod has a copper bearing that bridges the split.

[@FlightEngineering1]

No, the "blade rod" has it`s own shells and runs on a journal machined on the outside of the big end bearing block. This means that the blade rod only oscillates while the big end bearing in the centre runs a full 360 degrees as in any other engine.

[@robhavock9434]

Incredible technology that is not dated, in my opinion, as i am old enough to know how well-made things were done In comparison to today, different steal and aluminium not available today.

[@bobmorris4503]

Totally mind blowing. I have worked on one or two much much smaller engines - lawn mowers/scooters etc. To have the wherewithall that you clearly have is a great credit to you. Enjoy getting it all back together and then running the beast . I wish you the very best. Bob

[@richardtarr2745]

What a fascinating project on a beautiful engine! You clearly know the Rolls-Royce Merlin well and have the skills to restore it. A shame there's no way of telling how and when it crashed but I'm looking forward to seeing the progress back to a running piece of history. Thanks for sharing😎

Beautiful parts. Beautiful pattern work, beautiful machining. Thank you for going over the engine with a camera so well, and for posting it. I've never seen a disassembled Merlin before. Regarding the zero-oxygen water: seems reasonable the water in a pete bogg would be void of much oxygen.

[@brucemiller8109]

As an Airframe and power plant engineer in America I would say at 19,000.00DM? or USD or Pounds you did fine. Ive worked on P 51's over the years and can say that ANY engine cases/heads/crank/ supercharger part alone would be expensive. When I started working Mustangs back in 1974 you could buy a Yellow tagged (Military OH) engine for about 12,000.00USD out in calif...a parts dealer had over 100 FS, today same engine would be 250,000.00USD AND another 90,000.00 to have a shop certified it. Well done.

[@FlightEngineering1]

Thank you! Yes, they have got more expensive and parts more difficult to acquire here in the UK. The real killer was when Aviation Jersey sold out to Vintage V12s, that hurt!

That Merlin probably flipped on its back to play dead until the right guy came along. It appears, now, to be in good hands. Best of luck on the resto; you're doing the 'world' a favor.

[@buffaloj0e]

Amazing, I hope we see more of this. It’s fascinating to watch and not often seen unless you are in the right circles.

[@azazeldeath]

It still amazes me to this day just how similar engines really are, regardless of size, fuel type or even use (generator, car, bike, truck, boat, earth moving machinery or aircraft) of course to an extent, i was only a lowly automotive mechanic, actual modern day turbo fan engine ive never worked on, have worked on radials and even jet turbine engines once. But for the most part they are all very similar. Never saw the inside of a merlin until today, and i could follow along no problem.

[@jjhpor]

That first closeup of the bare lock at about 5:00 really reminded me of a Porsche 911 block. The details of the mounting surfaces for the cylinders with the skinny studs sticking out is a perfecrt match. The crankshaft seems to be built up instead of a single piece. Once again I'm reminded of a Porsche engine but an older one. The early 356 S engines had a built up crank by Hirth. He marvels at how clean the inside is. I've worked on car engines from the 1930s to the '80s and you never see modern engines that have only seen detergent oils with that much gunk inside. I've seen engines with 300,000 miles cleaner than that. I'm not refering to the grit from the crash site but the thick black goo everywhere. Apparently there is no separate cylinder head. That makes an amazingly complex chunk of metal to cast and machine. the old Offenhauser engine used in Indy cars was made like that. I assume, since the block assembly was aluminum that there were iron cylinder liners. Fascinating engine!

[@FlightEngineering1]

Yes, detergent oils are the way to go. The Merlin changed over to a separate cylinder head in 1942 due to coolant leakage caused by increasing boost pressures being applied.

[@rivalrepairs]

What amazing engineering went into that engine! it was impressive how it went from 1000BHP to 2000BHP over the length of the war

As a “non” engineer type, I’m not qualified to say anything about this engine but I’m amazed by its “cleaned up” state....I love the colours in the different components, something that you don’t normally get to see, unless you’re in a workshop environment and it’s not a bland expanse of “Silver”, either but a far more subtle mixture of mettalics....lovely to look at, even without a technical background! Good luck going forward....will you pursue it’s historical lineage, using parts numbers, etc, or is that too difficult to do, given that we’re nearly ninety years on?

[@stanleybest8833]

Divco rebuilds and inspects crankcases. I'd just compare RAF to USA practices. Cases don't always get shaved for rebuilds. A good engine found is a "Lucky". You should find parts spares. I'd restore it to ready but loose assembled, so it can be later inspected and greased every few decades. A few of my gaskets are leather. So are my engine mount ends. The cores are rubber carved with a Stanley Sureform. Wooden blades is also a good thing. Culver is a USA all lady propsmith. When you paint your mill, please don't try spray cans. A brush is more durable and economical. Spare accessories is a must. Keep a measurements and work logbook. I'd stay away from anything but regular Prestone and distilled water. Leaded gas isn't necessary, anymore. It runs 700 hours between rebuilds. Bores can be nickel plated but never chrome plate a bore or wear surface. I changed my prop seal every 50 years, whether it needs it or not, and the J&J Airparts lady was howling with laughter. A cooler thermostat is possible if you don't run it in the winter.

[@johnb5519]

We tend to think that the engines of today are so advanced, but it's such a surprise to see the design of these engines from that time period. If only some of the motorcycle manufacturers used some of the innovations in these engines, they would still be around.

[@FlightEngineering1]

True, it even has sodium cooled exhaust valves.

[@Classickoolcars]

Oh wow! That engine is in incredibly good condition taking into account the age, and the fact that it's been crashed, and buried for many years. The thing that really surprised me as much as anything is that you said that it was full of really dirty black oil. I would have expected better maintenence from the RAF / RAAF / RCAF ground crews!

[@Tera83074]

wow, i'm so happy to see this engine in capable hand, being restored. you say the crankshaft should have had a serial number stamped, but doesn't! Leading you to believe its been serviced and or rebuilt. i'm sure you would have told us if any of the other parts that also should have serials had them. But is there any hope that there are serials on anything else you haven't yet found? I can't help but feel the history would be so interesting, even more so if this is an engine that's gone thru rebuilds and possibly seen a long service. Given the location that it was found and the fact its rebuilt, possibly from spare/scavenged parts might that not also narrow down the number of airframes that it could have belonged to? I'm not british and english is like my third language so I could not hope to look thru RAF records, but if at all possible, finding the airframe and pilot of this airpale would be one incredible find. Good luck with the restoration and as a new subscriber i'll be enjoying your next episode with a good old cup of tea and biscuits!! Cheer's

RRHT have a cracking good book on the Merlin in the Halifax. The installation by HP was urm.. sub-optimal.

[@FlightEngineering1]

That`s right. I think the thrust line was different to the Hercules powered variant, which caused handling issues. The bearers were also (unusually) bolted together and not welded.

[@hoedemakerbart]

Well you have acces to many parts, for us mortals it would be useless, a static display only 😂. Nice job.. im curious to the end result 👍😉

[@anthonyxuereb792]

Maybe it was upside down because it sat better (and safer), it would have been rather awkward to put it rightside up without a stand propped up by the supercharger and ancillary bits and piece, it seems logical to me anyway

Aluminium doesn't 'corrode' like steel. The surface oxides instantaneously when in contact with oxygen, forming a thin, invisible, protective barrier against further corrosion.

The old wooden props, very early Merlin

[@yogiguitar1]

nice 1 ! id love one of them merlins especially as this ones got history. id build it into a car or a boat

[@nzsaltflatsracer8054]

7:32 That's interesting, I've never seen inside a Merlin before. The opposite cylinders are in line so the inside rod bearing runs on the outside of the outer rod bearing & that rod is 5 pieces. Was that a common setup on aircraft "V" engines back then?

[@patrickshaw8595]

Yes. Harley V-Twins and Allison V-1710s also used "fork-and-blade" connecting rods. Griffons used one "standard" rod with a gudgeon for a "link rod" to move two pistons with one crank rod journal. Of course nearly all radial engines used a "master rod" with many link-rods attatched to it.

[@FlightEngineering1]

Yes, absolutely right. As below, the Allison V-1710, plus all the other Rolls-Royce V12s except some experimental models. The German V12s used a slightly different idea with a common bush supporting both rods, and some Russian engines used a master rod and slave rod with a wrist pin at both ends.

[@smplyizzy]

I thought if an engine like that was to be used in an aircraft it would need to have a log book created and signed off on by an engine specialist? In that light, the components would need to go through a recertification process. No?

[@FlightEngineering1]

I am that engine specialist, but this isn`t going back in the air, mainly because it is an early engine for which there isn`t the demand. Nothing on a Merlin is "lifed", ie, you don`t have to have a record of how many hours it has done, you can pass all parts on condition, by visual inspection, measurement and x-ray flaw detection (NDT). Quite a lot of this engine could fly again, but not all of it.

[@Steviegtr52]

Sounds like it will be a good engine eventually. This popped up on my youtube, I think because i had watched Lottie the tank whisperer over in Aus i think. She is building one up now. Merry Christmas.

That`s a good question. I don`t have any history, but I am going to try and trace it using the engine number with the RAF Museum library.

[@mikewilson631]

This is the second Merlin/Meteor crank I've seen that I thought was quite grotty and needing refurbishment but the owner was happy to reinstall. Yours appears less grotty than the previous one but that may be down to video quality. The previous one had clear corrosion pits in the bearing surfaces. When you make the installation video, would you be so kind as to be specific about why you think it is acceptable to refit this instead of having it reground. My experience is with smaller, more highly stressed engines and I wonder if that is the cause of our difference of opinion. Interesting that the oil filtration was so primitive on Merlins.

[@FlightEngineering1]

The finish on these journals is ok, they are discoloured. As a non-flight engine, it can go, but to return to flight it would need to be lapped, or possibly reground, yes.
