The Facebook Marketplace Merlin Engine. EP3. Fitting The Crankshaft.

Next step in the rebuild of this 1942 Rolls-Royce Merlin XX engine is to install the crank. The engine once flew in a Handley Page Halifax heavy bomber in WW2.

I remember one of the lecturers at tech college telling me that he used to work at a factory making the Merlin shell bearings and they used lard oil as a cutting fluid. He said it permeated everything and stunk to high heaven and was discovered later on to be carcinogenic. Nice to see this progress Peter looking forward to seeing it completed and making noise. If it’s going that far.

Rendered Lard Oil is not carcinogenic (usually produced from Pork Fat). It sounds like what your lecturer used back in the day had other additives in. Food grade Lard (Oil) is used all over the world and is far healthier than many other animal oils and certainly safer that processed vegetable seed oils. If it stank really badly it sounds like it wasn't rendered and filtered very much as food grade doesn't have the pork smell at all.

So glad I found your channel, great stuff

[@clivelee4279]

Most interesting, thank you .

[@paulthompson8613]

Always love the stories that come with these engines

[@woodwelder]

Excellent video , keep all those extra bits and bobs about the design and performance coming …
Cheers

[@eddyd8745]

Thanks for taking the time to produce this. Fascinating stuff!

[@danieloltmans475]

I’ve always been curious how these engines go together, great content. Also, do you have a video detailing your background? If not I would be interested to hear more about what got you into this type of work.

[@ralphedelbach]

Sound quality and level varies a bit too much for my 85 year old ears. I assume you liberally lubricated the main bearing before you installed the cap at 5:47 although you do not mention doing that. It is interesting to see how this great engine is put together. Thanks. Will we get to see and hear it run sometime?

[@TheMontyrex]

There isn't a word for this video but fascinating will have to do.
I can't wait for the next video. THANK YOU.

[@davidlawrencebanks4610]

Brilliant! Enjoyed that thanks

A Britsh mechanical marvel when it was needed most !

[@Michael-he7xn]

Fascinating information. Thanks

[@rockyrivermushrooms529]

amazing engineering. Im fascinated by older engines.

[@kiiiisu]

very cool thanks!

[@DarrenPhillips001]

There’s a good book by sir Stanley Hooker who was chief engineer at Rolls Royce. He was involved in improving the supercharger. V interesting video by the way.

[@johnmerrifield424]

Great videos Peter I am learning so much that I will use during my Merlin mk25 talks/demos at de Havilland aircraft museum !

[@zaharib]

Thanks so much for sharing the journey! Nice job with the crank web attachment tool 😊❤

@FlightEngineering1 - Coolest YT video of '24. 👍👌

Thanks for the 'fretting' info; I had been under the wrong impression that the bearings were what lost material, so I never understood how P&W's introduction of a silver shim on the rod/rod cap mating faces did any good. Much enjoy seeing the Merlin at 'parade rest.' It's hard to believe how judicious was the use of material until you see any stripped block. I saw a stripped 4360 crankcase that just looked flimsy. It had fixed, helical rings whose function seemed to be to cancel crankcase twist under power. I may be taking it too in I suggesting that the Merlin's use of exterior oil lines was not so 'retrograde.' Adding material just to ensure oil passages is not without penalty.
