Dave has beat me to it ! Bongo (B1) by Chris Vine ! Noel.

The eighteen cylinder radial engine made by Gerald Smith – a simply awesome example of machining skill and especially so when it was made on a treadle powered round bed Drummond.

I've only seen it the once and never had a camera but it's etched on my memory. Seen many fine examples of the art over the years including the superb models of Cherry Hill but none eclipses that for me though Peter Southworth's Agnes tandem compound stationary engine comes a very close second.

As I rarely get to see models in the flesh (it's all wallabies and sugar cane around here), I would have to say the recent thread Doc posted HERE (see page 19) about the model of the engine room of the Deutchland is the best example I have seen pics of. Seen at the Hamburg maritime museum, the workmanship and detail is boggling and the subject, a six cylinder quadruple expansion engine is unique. But it is surrounded by the full engine room full of equipment with details like a Stuart V10 driving the condensor cooling pump etc. Just awesome in both extent and quality.

From Doc's thread:

Also some Stuart Sirius engines there I think:

I can now appreciate the skill and time that went into this amazing model.

I have been looking at ME mags since I was a boy in short trousers and this takes the cake.

For me it’s armour like this. Made without anything in the way of advanced tools. Made to fit the men like a second skin. Plates formed by nothing more then a man’s hammer and skill. Not only did this need to look great by the use of the skill of the finest artists of metal and design. But the metal craft in getting the correct temper of steel took a depth of knowledge long lost.

Thanks Hopper,

Yes I agree those pics you reposted of that engine room…..magnificent!!!

Very much on the same general theme of Cherry Hill's work, Ron Jarvis' collection of early and significant engines built to quite small scale but fully-working, to highlight their historical significance in engineering.

These included models of:

– The strange steam-powered bus built by Church (Apparently the prototype was built but proved a disappointing failure without ever entering its intended long-distance service.)

– Newcomen's 'Atmospheric Engine'. Standing perhaps two feet high, the details extend to correctly-bonded actual bricks, to scale size; properly-sqaure nuts and bolts on the timber frame etc, and real lead pipes made to right size and correctly soft-soldered to join them. Ron admitted he could not use coal firing reliably in a 2psi gauge spherical boiler about the size of an orange – and with orange-peel finish to represent 18C manual plate-forging – so it contains a discreet electric element controlled by concealed thermostat and microprocessor. He joked about this being unique as an 18C CNC steam-engine!

– a diagonal paddle-steamer engine, in timber hull section. I think this was the one competing for Gold with another's work of equal merit, but had to be content with Silver because the judges were unsure if the castings should have been painted. Errr, they had not realised the model's iron castings were actually mild-steel fabrications treated in a home-made grit-blaster with the correct size grains, to emulate castings….

.

Outside of model-engineering, Mr. Jarvis spent his retirement from an MoD Science career, gardening, teaching himself computing when you needed know programming to use a computer, and bee-keeping. It seems in the last, he was the one who probably cracked the insect's curious 'kamikaze' myth – it fatally injures itself only when stinging an animal with a tough skin such as a horse or human, not fragile ones like other insects.

I do not know what happened to his models after his death – already a widower. I do hope they and the awards they garnered at the major exhibitions, are available for others to admire; preferably in a museum run by curators who understand their subjects, not just how to fill the premises' private store-room behind the gift-shop.

.

I shall now admit bias! I knew Ron Jarvis as a fellow-member of our local model-engineering society.

These memories raise another….

I helped take his collection back to his home after a local exhibition; and carried the Newcomen Engine from a car, across crazy-paving, and up three steps into his house. It is (I nearly wrote 'was' )  a heavy, bulky but very fragile arms-full, and I was very nervous; thinking afterwards as relief took over that if I had tripped and dropped it……

Even now, years later, it still makes my blood run cold that by a single slip I would have destroyed Ron Jarvis' Newcomen Atmospheric Engine. Breaking his heart; and my being whispered about, even pointed out, in clubs and exhibitions up and down the land to this day.

. . . .

Incidentally, though not a leading exhibitor, another and earlier club member, Reg Dawson, was a consummate craftsman who overhauled the 5" g. 'Maid of Kent' that was the club's locomotive. He might even have helped build it originally. It was with this that I learnt to drive miniature steam locomotives in my Junior Membership years, back in the late-1960s.

When I knew him he was constructing an exquisite triple-expansion engined tug he told me he had willed to the Science Museum. Not for hiding behind the gift-shop, we hope.

This character moved away c.1970, with the loco….. And neither were seen since. As he was in his 80s, then I think it safe to name him!

I would love to know if the locomotive, bearing the 'Maid of Athens' name-plates for a reason I long forget; and I think fitted with Joy Gear, still exists and despite my novitiate handling, hopefully still sometimes romps around some club's track somewhere….

One deserving of a mention is the 1/30 scale horizontal Corliss engine of Jerry Kieffer of the US. Deceptively simple looking, until you realise that everything is scale, including the 1/4 diameter bolts on the original. How you go about making taps and dies to produce a 0.009" diameter functional bolt I have no idea!

Clem Tomlinson's Deltic Engine deserves a mention. i would love to see it close up.

Plus one for the engines of Commander Barker. I always made a point of visiting the Merseyside Maritime Museum to view them, but I believe they are no longer on display. Even more impressive when you realise they were made with treadle operated machinery.

Other people's work is well out of my league, so not an ego trip, but the most satisfying models I've seen are the ones I made myself.

Can anything made by someone else ever beat the joy of a home-made engine or clock firing up the first time?

I really like Barry Jordan's machine tool models, particularly the Bridgeport….

Great model but also unique.

The many examples quoted just go to show the immense range and magnitude of the skills within the Model Engineering environment.
