Model steam engine for tug Maarten

I built this engine between 1997 and 2003 for my model steamtug Maarten.
Deze modelmachine naar eigen ontwerp heb ik gebouwd tussen 1997 en 2003. De machine is bestemd voor mijn model van sleepboot Maarten. De hoogte van de machine is 130 mm. Op deze video draait de machine op 1 bar perslucht.

wow a real masterpiece works like a Rolex thanks for sharing

[@richardkelltoolmaker]

This is a really fine engine, I also like how the thing is run slow as per a real engine, these little miniatures whizzing at so many thousand revs seem ludicrous, proves nothing.
Wonderful workmanship and a real sense of 'atmosphere'.
Well done !!

[@EddieMoonWalker]

Prachtig gemaakt en de sleper is ook prachtig!!

[@WalpotJ]

@SteffanLlwyd
Thanks Steffan. The valve gear is Hackworth. There are 3 pomps on the back. The first is a coolingwater pomp. The second is the air pomp. The third is the boiler feed.

[@WalpotJ]

@landus94 It only looks like a triple-expansion engine. It has 3 pistons of the same size. The boiler pressure is 3 bar and a real triple wouldn't work because of condensation.
Regards, Jan.

Gorgeous engine. Just found your channel and subscribed

[@ph11p3540]

Triple stage steam and he managed to put a little condenser cylinder off to the side top of the engine. I see most model steam engines as open loop and exhaust water in 15 min. This is closed loop is really amazing.

[@rongeremy6970]

WOW!!!!!!! HOW lovely is this engine,,, I'd be very happy with this for sure. Beautiful, piece of work.

[@WalpotJ]

I designed this one after I had seen several engines on several tugs.
Regards, Jan.

[@FrankRuffolo65]

only quality builds can run like that, folks. great sound as well.

[@JohnnyPhoenix]

I thought it was huge at first, that's before you moved that valve!

[@WalpotJ]

Thanks everybody for the very nice comments.

[@WalpotJ]

@ rhavrana. Thank you very much. Because of the 3 bar boiler pressure the engine isn't a real triple. Bore x stroke = 13 x 18 mm.

[@richardkelltoolmaker]

A fine piece of work.

[@robertmayhew98]

So amazing. Thank you for sharing this. 🤗

[@WalpotJ]

Thanks for the compliment, I like your work as well.
Regards, Jan.

[@eddiestafford3313]

[@modelleg]

[@pepewiwi]

Fantastic made!!!

[@luketremble9782]

Wow sounds perfect

[@ikwillet]

absolutely beautiful!

[@WalpotJ]

@CHRISANDELLIOT123 Thanks, the engine was running on 15 psi compressed air. Regards, Jan.

[@WalpotJ]

@wat3randfir3
Thank you very much. When the boiler is ready I hope to do so. It may take a while.
I'm sorry but there is no plan for this engine. I designed it myself and never made a complete plan.

[@CHRISANDELLIOT123]

wow man, very impressive engine, absoultely love the hackworth and the 3 pumps off the back, was the engine running off steam or compressed air?

[@gorduche69]

trop belle course longue couple elevé

[@Calin1000]

Wonderful engine, congratulations. Please post a video of it running under steam too.
Are plans available for this eingine?

[@WalpotJ]

@cellyboy3000 Tijdens het bouwen krijg je ook steeds meer respect voor techniek van vroeger. Groeten, Jan.

[@mayol74]

That is a fantastic engine you have built there. I have never seen that kind of reversing link before, does it have a name or is it somthing you have invented your self? Do you have drawings for it, showing the reverse link and altso the linking of the vacum pump?
Very nice work

[@Tjalmann]

Very nice engine. Would love to buy one :P
As im building a old themed RC boat

[@WalpotJ]

@cardinalvincent
Bedankt voor het compliment. Groeten, Jan.

[@wacobleu]

beautiful beautiful engine

[@WalpotJ]

@DasBootU96 Bedankt en over het vermogen maak ik me geen zorgen. Is ruim voldoende. Groeten, Jan.

[@DELTA1DSV]

Hi great engineering, many thanks

[@landus94]

It is triple-expansion engine, isn't it?

[@WalpotJ]

Thanks, the reverse is "Hackworth" type and sorry I have no drawings.
Regards, Jan.

[@barumman]

Very nice work, Congratulations.

[@WalpotJ]

@67amigo
Sorry dat ik nu pas reageer maar ik was op vakantie. Daardoor moest ik helaas Dordt in Stoom missen. Bedankt voor het compliment.

[@Hunter-sq9wf]

Are there any plans available for this? It's a really nice little engine.

[@overtakeNeps]

Hello Jan
Fantastic work!! Do you have a plan or something of this engine? I wanna build a engine like this for my glasgow.
Regards, Constantin

[@HistoricSteamTV]

Incredible,I am still to get a reversing single working! LOL! Will you build me a good 5/8" bore uniflo racing engine?

[@rhavrane]

Hi, Congratulations,, I confirm, this is indeed a wonderful engine ! Complicated as I love, It fully justifies more technical details to be shared ;+)

[@WalpotJ]

Thanks and sorry there is no plan for this engine because I never made it.
Regards, Jan.

[@WalpotJ]

@modelleg Thanks and regards, Jan.

[@evilamish]

I would love plans for this engine

[@75echo]

WOW!!!

[@haraldhardrada2865]

Это очень круто ! Спасибо за видео ! Незнаю поймете меня или нет )

[@WalpotJ]

@evilamish
I'm sorry but I designed this engine myself and never made a complete plan.
Regards, Jan.

[@crapthisisalongusern]

This here is a triple expansion engine right and its running on air?

[@janwalpot3960]

It only looks like a triple. A real triple would not run like this. The pistons are equal.

[@serpentstudios7768]

Kazoo its cool

[@mnewlyn]

have you sailed the Maarten yet?

[@janwalpot3960]

No She is not ready yet.
