Beautiful work Mactin. Reminded me that I had seen a series of articles in the Model Engineer January 1959 illustrating the build of an A Class submarine should you ever wish to put your engine to work.

the fear of losing bodily parts was enough to keep us away ,changed days i remember him having bottles of meths and matches in the bedroom for the engine which powered a workshop with a small circular saw a power hammer and other potentialy lethal tools no health and safety in these halceon days ,next time i see him will have to ask what happened to it knowing him it will be up in his loft

The ball is actually a door knob,got two of them from a charity shop for a quid its ferrous because its magnetic. The "meccano" is the poor mans variation called "X Tech" the hole spacings are different and its dirt cheap, once again courtesy of Marie Curie cancer charity shop. I presume you still have a full compliment of digits and bits! older brothers! mine was exactly the same.

another wonderful work of art . is the sphere stainless steel ?,like the Meccano ,memories of a lost childhood my older brother had a huge box of the stuff with a mammod engine and me and my brothers couldnt touch it if we did the threat of losing parts of the anatomy or death was there to stop us

Beautiful! Excellent. Not a toy by any means. You sir are an engineer.

Cheers

Cos "the other is in the Albert Hall" 😉
