As an aerospace machinist of 30 years that is simply amazing...

@mattstevens4667 4 года назад

I have just purchased a casting set for this model and got together all the materials.....expensive but very impressive engine also. I purchased it with money left to me in a will from a close family friend who passed away just over a year ago - hence once i get it complete, it will be called "Stan". Beautiful engine and the one shown is to a very high standard!

@guywren4801 3 года назад

Such ingenuity and skill - thanks for showing. I notice that the flywheel needs a little turn to get it going - how is this managed with the full size?

@keithappleton 3 года назад

The large full size engines often used a "Barring Engine" to turn the crankshaft into the correct position to start. Sometimes something called a "Simpling Valve" was used to admit steam to more than just the high pressure cylinder to start the engine.

@johnutting9615 12 дней назад

Somewhat surprising that a 3 cylinder needed hand starting. Would have thought it would have been a self starter. Comment

@keithappleton 12 дней назад

It is a 3 cylinder 120 degree crankshaft compound engine and would need a special "Simpling Valve" which allows steam into the other cylinders other than than just the first high pressure one, to allow self starting.

@@keithappleton got it,I'm used to 90 deg crankshafts on twins. Thanks

@nitro105 4 года назад

Great little engine keith, I noticed that you had to turn it off dead center to start it, would a full size engine have a starting valve that let high pressure into the low and intermediate steam chests for starting? something like an intercepting valve?

@keithappleton 4 года назад

they used a "Simpling Valve"

@TimsBitsnPieces 3 года назад

Keith, what are the 2 pumps on the side of then engine for? This is a magnificent machine, it looks and sounds fantastic.

@keithappleton 3 года назад

One is the boiler water feed pump and the other larger one is the condenser vacuum pump.

@paulrayner4514 4 года назад

just out of curiosity should this engine be self starting? or is it because its still a bit tight? I would imagine on the full size one's they will be, or do they have to stop them in a certain position like they do with beam engines. It's a beautiful engine and nice to see it running rather than stuck behind a glass case.

@keithappleton 4 года назад

Compound steam engines generally do not self start unless they have a "Simpling Valve"

@JamesPetts 4 года назад

Incidentally, given that there is a displacement lubricator, what is the purpose of the cylinder oiler?

@keithappleton 4 года назад

What cylinder oiler, I see a water pump and a condenser vacuum pump built onto the engine but no mechanical lubricator . . . hence the Displacement type.

@Herby-1620 4 года назад

I find these very interesting. The big question I have is how much power can/do they produce. Can you hook up a dynamometer or some such that might indicate what such an engine would do under "load". I understand these little engines can be quite powerful for their size. Great video and video series.

@douglasmcdermott2830 4 года назад

Herby1620 The Stuart triple from memory isn’t terribly powerful, but the Stuart 5a produces 1 1/4 horsepower at either 300 or 3000 rpm, I can’t recall which. They also make a very large compound launch engine which has been known to generate 2 1/2 hp.

@DAKOTA56777 4 года назад

@@douglasmcdermott2830 The Stuart 5a is 1.5hp with 100psi at 800rpm, listed on Stuart's site. 3,000rpm is... quite high, for a steam engine.

This reminds me of the large 3 cylinder engine that was at our works until 1978, I started work at British Steel, River Don the following year so never saw it, Had to pack in last year due to the after effects of the virus! 🙁 It's at Kelham island industrial heritage centre now and is (Or was before covid!) Steamed up every so oft, I'll have to get there and watch it sometime! Love your vids by the way 👍🙏

@royseifert3078 4 года назад

Keith, when you changed from forward to reverse, then from reverse back to forward you had to start the engine by hand, why is that? Another great video and fun to watch, thanks.

@keithappleton 4 года назад

Compounds are generally not self starting unless the cranks end up in the right position . . .

@johnutting9615 4 года назад

Can be considered to be a single cylinder enngine

@Genius_at_Work 2 года назад

@@keithappleton That's why real Compound Engines have a Bypass Valve to pass Steam around the High Pressure Cylinder directly to the Medium/Low Pressure Cylinders, incase the High Pressure Cylinder came to stop in TDC/BDC. At least Marine Engines have that, as they must be started many Times when Manouvering. Stationary Engines like Generator or Pumping Engines may have to be slow turned to Starting Position instead, as they aren't started very often.

@krzysztofjaxaswist1434 3 года назад

I know that this may be a little crazy idea.... But do You think that a small engine like that with some reduction in revs, would be able to power a 2 person lightweight "car" like wehicle build of bicycle parts? I mean ...human power on bike isnt very much and it runs... now taking the torque of steam ... Could you comment on that idea?

@keithappleton 3 года назад

Not powerful enough and it would prematurely wear out. It is after all just a working model Steam Engine.

@krzysztofjaxaswist1434 3 года назад

That's what i thought... But hopes were high 😁 A nice triple expansion steam engine on my imaginary car looks just perfect. Single cylinder launch boat engine just doesnt give that wow effect. I don't want to take too much of your time on my idea, but what would you recommend? Building it from scratch or is there somebody that makes bigger steam engines than that beauty you showed here. Btw. Im learning plenty from your videos and hope youre not going to stop anytime soon 😊

@keithappleton 3 года назад

There is a commercially manufactured steam car available, and they are not too expensive to buy. It is called a "Likamobile". maybe by Googling the word you may be able to find more details about them. I found a picture of one here: www.stationroadsteam.com/likamobile-steam-car-stock-code-3767/
