Hi Chaps
Spent a short break in London.
As well as viewing our loot in the British Museum :- Elgin marbles, Roseta Stone, etc etc etc.
We also visited the science museum in Kensington. Full of Kids pulling handles and pressing buttons on the interactive displays, getting in the way of the bigger kids like myself, who wanted to pull the handle and press the button and work out what it was all about:- they should have adult only days for miserable old sods like myself.
Any way they had some great engines there her's a few pics.
Newcomen atmospheric engine yes that's the date it was made 1791




Steeple engine (I think)

Twin Compound horizontal mill engine, this one was coupled up to steam and they ran it for about an hour, absolutly fantastic it was amazing just how smooth running it was almost silent and hipnotic I loved it :- The kids wern't interested to busy pulling handles and pressing buttons.


And Babages difference engine an early attempt at a computer.



Wonderful workmanship
Also went to Greenwich to see Harrison's marine chronometers:- H1, H2, H3 and H4 I was spell bounded by them it re kindled my ambition to make a clock

If any one wants a good read I would recommend John Harrisons auto byography:- The story of Longitude,
Harrison would have made a great madmodder he's one of my big heroes.
