Hey! 😲 I had a basic one when I was a lad in school. I took it to class and we ran it, it was a huge success. And I still have it today. I got an A+ on that project 😄. I remember, I blew the whistle and the girls screamed holding their ears hehe. It was terrific.
Thanks, good video. That’s positive feedback! The system demonstrated used negative feedback, i.e. sample of output subtracting/negating input to stabilise output.
1:22 Where can I get a Professor Simon minifig?! Ok, I know, it's probably "Doc Brown" from that movie. (Which, coincidentally, one of the sequels features a steam engine!) I suppose Retrol might have had their hearts in their teeth until you successfully diagnosed the problem. Fortunately, it was a simple error anyone (including an experienced machinist such as yourself) might commit and not a problem with the kit itself. The fact that you didn't simply give up and blame the product, but applied troubleshooting skills and prevailed, should be encouraging for everyone.
It's interesting to see you run your steam machines on compressed air. Some decades ago on TV shows like tomorows world they showed these very light taxi's that run on compressed air with a big carbon fiber tank. Apparantly there are still a bunch of companies working on them. But they dont have the same range as petrol cars i guess. But i guess only recently with electric cars people start looking at alternatives. Just read something that someone bought a hydrogen car for $50.000 but now it needs a new fuel cell a repair will cost $100.000 as they only made 1000's of that car. Alternative energie isnt easy .. but the advantage of a compressed air car is that its relative simple and has relative simple parts.
Thats a fun looking model Prof Simon! did you have to machine/fettle any parts or did it go together without problems? (except for the timing issue you had)
It's more fun when they don't work I think! More tinkering but for free haha. I would dearly love a kit if anybody wants one made for them. What oil do you use Simon?
@@SimonHollandfilms This stuff is awesome. There is a 3M version of it also. I was introduced to it at Sheffield's Rolls Royce AMRC. I could be shot for telling you that ha ha haa. Love to show you the 3-meter diameter chucks we used to install. With a runout of 3Mic. Some of the smaller parts loved that juice!
@@dean5263 Clearly it's a technical term, dating back to the mid-nineteenth century. You see, @dean5263, engines in those days ran on _steam_ and, like our modern generators, had governors. The difference between then and now is those early governors featured balls of brass, such as you see here on Professor Simon's machine. Whenever the chamber gets hot, the pressure builds up, so the balls come out, maintaining optimal stroke speed.
Thank you, I thought it meant to run it at full speed where the governor balls were all the way out because of the centrifugal force.@@DistracticusPrime

what fun
Got one under the Christmas tree, just waiting to be put together.
enjoy...I run mine all the time. nice engine. ...boiler is too small
Thanks for your video, Professor!🥰
nice engine, fun to build.

they made a good steam engine model and the ball governing system really works.
I had one of those kits when I was a kid in the 70s
That's pretty cool, Simon! I always enjoyed the Stirling engine kits myself:)
Me too!

yes...the figure was a doc brown from playmobile back to the future toy
Honestly for $300 I can buy a 5.5 Hp gasoline engine powered generator. Still love the steam engines. Biogas is also awesome.
Ooh! Ooh! Where do you live, where a 5.5 Hp generator is only $300? Around here they're 10x that. Whatever, I'm omw with cash!
Harbor freight! @@DistracticusPrime
These are awesome these and sterling engines.
Love it! I want one.
You should!
I'm sure those blue boxes would be quite expensive... 🙄

no machining it is accurately made. the problem i had was me not reading instructions...ha

Hello Sir. I have a question I have been unable to find a good answer for. Why don't we use subduction zones to dispose of hazardous materials?
good question..i wonder how fast they would move and if they return to the surface....needs careful geology
It's more fun when they don't work I think! More tinkering but for free haha. I would dearly love a kit if anybody wants one made for them. What oil do you use Simon?
So true!, oil, i use a light oil on models 3 in 1 type or marvel mystery oil is great

When in doubt - read the instructions. ;)
last resort...ha
cool
Balls out
I wonder how many people know what that means?

@@dean5263 Yes, you are correct. Also, there is a double meaning, if you read it a certain way. 😉🤭

My mom says that I can't play with you any more.
