Lego Technic Napier Deltic Marine / Train Engine

[JesusMcCloud]

Great work!

I tweaked it a little (see my video response) so that all three cranks turn at the same speed

[faturesop]

yo. can u show how to make it please. its for my desil

[1madaboutguitar]

FAKE

[CornishMorgan]

@1madaboutguitar lol hardly

[baldbloke]

Amazing - it even sounds like a Deltic (well, as close as you can get anyway!)When do we get to see the opposed-piston version complete with phasing gears :-)

[legostalwart]

@baldbloke I'm not totally clued up with Deltics (never seen a real one) so might've misunderstood the question, but when I built this, the gearing was designed so that one crankshaft ran opposed to the other 2 so that that phasing was correct.

[aSirludvig]

More power!

[D1013wezzo]

Wow very nice I'll like to see a Maybach MD655 . I'd like to see a Lego class 52 :) but like wow

[MrFlavioValentino2]

how could you build it?

[seasonedtoker]

I was always wondering how much heat from friction do these plastic parts create?

[legostalwart]

@seasonedtoker Zero heat in the short time that I ran it - the tolerances aren't very close at all and plenty of moving air.

[PalomboDylan]

@legostalwart WHERE DID YOU GET THIS!?!?!?!?!? PLEASE TELL ME!!!!!!!!

[AlchemistHawk]

@seasonedtoker nothing at those speeds probably. But i took a simple V8 version of these lego 'engines' and hooked it up to a 32,000rpm dremel... melted the crank and the cylinders were a little hot.

[CornishMorgan]

@AlchemistHawk lol nice, so im guessing about 20000rpm is as fast as ya wanna go with lego. thanks, saves me the job to testing.

[ChargerMiles007]

Awesome work!!!

You must like Deltics as much as I do!!!! :)

[torino390]

yes, it even has the same sound! that's clever stuff!

[07jkearney]

what is powering it?

[legostalwart]

@07jkearney There is a Medium Lego PF motor geared up 3:1 running out of shot. It's possible to fit the motor inside of the cylinder triangle in order to hid it, but I've not yet tried fitting one in there with additional gearing.

@legostalwart

its upside down!

[legostalwart]

@tpvalley I did wonder how long it would take someone to spot/mention that, the cradle was built as an afterthought just to provide a video of it running. This engine now has a partner, along with a transparent Baby Deltic, just need to get them on here sometime.

[legomaniacman]

Amazing engine, never heard or seen that kind. Sounds nice to :)

[radbot1]

That's awesome!

Is it just me or does it even kinda sound the same as the real engine charachteristicly.
