Ah yes, the satin sheen on exposed steel parts, and general patina, of a well-used, well-loved machine or tool… One of my tap-wrenches is now becoming too worn to be very useful, but years of mine and previous owners' hands as well as predecessors have given it such a sheen and pleasure to feel.
This reminds me of visiting the tiny, 13C church in the French Pyrennean village of Ste. Engrace. The columns' plinths are decorated with stone balls, about tennis size; and I noticed some were black and shiny whereas the rest of the stone retained its limestone creaminess. I realised from their location, those ones had helped all those generations kneel for Communion: the patina from thousands of hands over hundreds of years. (My girlfriend wrote one word in the visitors' book: " Peace ".)
The satisfaction of using any very old functional article – not necessarily a workshop tool – as intended, when and where its use is still legitimate in purely practical terms….
Though including a large carpenter's trammel whose hardwood rule's brass-end fittings look (at very close inspection!), hand-made; or a very useful, neat little adjustable-square with 4" blade. I so wonder of their history.
The scent of clean oil…. The pleasure of using a bench drill, a Meddings so a good one, that was second-hand to me but actually has no lazy-holes in its table!
The neat contrast between 18C interior-decorating elegance and 20C modernity in a former town-house used by the IT training company my employer sent me to.
The slow, very soft, almost inaudible, " whoomp whoomp whoomp " of a large-scale (6"? It was certainly 4", scale) Showmen's Road Locomotive ticking over, though still generating for its canopy lights. (I wonder what would be the common reaction if someone displayed a miniature or indeed full-size SRL without canopy lighting?
)
The rhythmic splash-splash-splash of a large water-wheel in a restored mill, while hardly a sound comes from the cast-iron pinions meshing with the hardwood "cogs" of the larger wheels. ("Cog" here is the millwright's term for the teeth, but not the gear as whole.) …..
…. and this lead only slight obliquely to…
"The click of a ratchet". Ah yes…
Just outside Sherborne, Dorset, is a Wessex Water fresh-water treatment-plant alongside its predecessor, a bore-hole pumping-station driven by a water-wheel. This has been restored to demonstration state as central to a local water-supply museum by a Trust which holds occasional public Open Days. (I am not a member, but yes, this is a plug – it's a charming little industrial museum to visit, the sort more conserved than pickled!)
The wheel-driven pumps were replaced in due course by steam-driven ones, in turn eventually displaced by electric of course. The Trust found a similar engine, and installed it with a coal-fired vertical boiler in the original shed. Built by E.S. Hindley & Sons, of Bourton; not very far from Sherborne, this single-cylinder mill-engine is so quiet the only sound is the soft tick-tick of its lubricator ratchet.
On one visit, I saw the volunteers had placed a small hot-air engine on the valve-chest, cheekily using heat escaping through the casting!
The water-wheel, also a Hindley product, had rusted beyond repair. It is on display, and the working wheel is a replica by preservation-engineer Richard 'Turbo' Vincent, fittingly near Bourton and Sherborne. He was also the builder of a replica Hindley Steam-wagon, to commission, and which uses a pair of wheels that are the only known remains of any original Hindley wagon.

On a very different metallic " tick ", I can assure you that as also a caver, when you are dangling from a rope with a hundred feet of dark thin air below your tootsies, there is nothing more reassuring than the sharp, metallic " Click " of a karabiner snapping shut on the belay!
