The first thing that struck me was all those draftsmen at drawing boards. No CAD, no Solid Works just sharp pencils and good erasers. Painstaking attention to detail without the benefits of being able to change stuff on the CAD assembly and have it translated to the respective drawing. Nope, that required a complete redraw of the changed part plus any other bits involved. Oh, and no CNC, Just highly skilled people doing their thing. Interesting, specially for one who had the good fortune never to experience the horrors of war. My thanks to those who fought for our freedom on whatever continent we now dwell. John B |

My mother was a traser waxed linen was placed over the drawing and a coppy made in India ink , then it could be printed and it was blue , they were hit three times by bommers even iff it missed the drawing office the tracing moved and she had to start again , women realy did there bit . |

What an excellent video. Thankyou for sharing. IMHO the merlin was a very impressive piece of kit for the time, and massively successful. Rather surprised in the commentary about heat treating the alloys that the temperature was kept within 2 degrees centigrade. In those days I thought Farenheit was king. Also the speed of the turbocharger radial fan at 20 to 30,0000 rpm WOW. Reminds me of Miss Tillys orifice (https://en.wikipedia.org/wiki/Miss_Shilling's_orifice) , a good piece of lateral thinking. Best Regards picclock |
