If you do tutorials again, and please do, please paint each independent piece of pipe (blocks connected to eachother and located in between 2 or more bearings), like you did at 3:37! It makes things so much easier to understand. Such a simple tweak can be a great visual aid!
In an engine, cylinders usually combust one-by one. It's rare that two combust at the same time. For example, in a four-cylinder engine the ignition order can be 4-2-3-1.
What you made is the valve that makes the piston go back and forth .to get over the "dead spot"the other side has a 90 degrees offset to keep it running smooth
There is another valve gear called Stephenson valve gear were all the reversing parts hidden underneath the boiler but a pain in the but to build but a fun challenge 😊
Bear in mind that a steam loco's valve gear doesn't only determine what direction the engine runs, but also the length of time steam is being admitted into the cylinder with each stroke back and forth. You use full gear (front or back) to get started, and as the loco accelerates, you pull the valve gear back towards center to cut off the steam earlier and work more by expansion of the steam than by volume. If you left it in full gear all the time, you'd be eating up more steam than the fireman could make, and the engine would be working against itself with back-pressure, basically not being able to push all the exhaust steam out in time before pulling in fresh steam from the boiler.
The way this one works is showing Kan's big brain, he has invented a completely different way of it working! The proper system changes the timing on the valve gear instead of forcing the wheel into a direction, he may know this by now though because of Hyce.
I was just working on this kind of thing in scrap mechanic right before i clicked on the video! I love trains so very, very much, and I'd love to see you make a steam train!
A steam engine mounted in a frame on wheels is a steam locomotive. A train is the locomotive with its tender if any, and load of trucks, carriages etc.
The valve gear does not give an initial push, that deadzone is counteracted by the wheels pistons being 90° out of phase which remove any deadzone, and the valve gear's purpose is to reverse and decrease steam admission at highers speeds/lower loads, thus reducing the steam consumed
Actually, all steam engines have valve gear, walshearts, baker and stephenson being the most common. Walshearts was made to have an easy to maintain valve gear outside the frame. The large back and forth yellow piece was connected to either a "johnson bar" or a power reverse. The johnson bar was a mechanical reverse, typically a lever in the cab that when pushed forward, would make the train go forward. After a while, you would have to pull the bar back to about 25-50% forward to go faster. A power reverse used steam from the boiler to changd the position of the "bar"
kinda correct the reverse gear turns the return crank (shown in your video) but it also moves the valve rod (valve is the one that decides wich side of the piston the steam goes) so changing the reverse gear to the extremes makes steampass trhough the valve piston a lot more time thus more steam on the piston, that's good for condensation in there and making the first wheel turning but then you've got to turn that reverse gear closer to the middle so the valve piston let's less steam go into the piston and saving precious steam (this gas expands A LOT).
so in the reverse gear, going to the extremes is like the first gears on a car, the low gears. Then when you already get the inertia you can change the link nearer the neutral point and it will go faster but it wont help in the first movements. further from the neutral = slower but with more traction. Nearer the neutral point = faster
To stop it chugging you would need the second drive in conectionits why steam engines have 2 or 4 driving cylinders. But to make it's simple for scrap mechanic look up the Shay locomotives, their steam drive is 3 cylinders pointed down to a geared shaft to drive the axles. It seems like the best option.
this is lovely, but not quite how the system works (though I have just been spending the past few days trying to figure out how they work, and there really isn't much info beyond websites that look like they were made in the late 90's!) what is amazing is how it still works! some real backward engineering right there! fantastic!
Yes, it is not nudging the crank-arm at the wheels in a certain direction. It is only shifting the valve inside the piston so the timing is different, that way it can run in reverse. And the problem with the deadpoint (the maximum or minimum point of action) of the piston and the (fly)wheel is solved by placing the crankarm of the wheel on the other side of the train at a 90° angle. So when one set of wheels and piston is at it's maximum/minimum throw/action, the other set is in the middle of the throw/action. No matter the position the train stopped at , it can always start driving again without it having stalled.
If you do the steam train use thruster pistons ( u know use a thruster for the pushmotion of the piston) u get the extra steam engin kinda noise :) Also bridgecrane
3:37, the Eccentric, 3:43, Drive Rod, 3:49, reverser, 6:35, you are talking about British and German trains, also, look up the American 4-4-0 locomotive, it is easier because it has valve gear in between the drivers
The reverser controls the direction of travel you would put it on 100 when starting to move when over 10 mph or kph tou would lover it to get faster speeds if you dont understand have a look on the internet
All steam engiens had valve gear. Some had the valve mechanism between the wheels attached to the axles. Some had the outside with the pistoms and some had pistons and valves on the axles. (Between the wheels)
Raaabon Laaanon yes the stevenson method has the valve gear between the axles. What I like about this method is it is completely external to the chassis of the train
Great... I finally figured out how to make this and I start doing my details last night and kAN uploads this today... Great... Ima be called out about copying... Thanks kAN...
Another system used was the stephensons valve gear, which was an earlier system. Also, as other people have said, this isn't a true representation of walhscherts (its pronounced wall shirts by the way) but it is most likely as close as you could get.
Yes I looked at the stevensons as well but I thought this one was much cooler. I agree its not perfect but I thought it was pretty close for Scrap Mechanic :D
Could you put it on the workshop anyway? Maybe it will work- who knows. I wanna see if I can make a steam engine with that, and I would give you credit if I put it on the workshop. Also, I've made a succesful 2-directional train with a 3-piston pipe system, so could you tell me what you think of it if I share it with you?
i think you should make a train and i know either durf or lordpain has train wheels and train tracks in one of their mods which would be more realistic than default wheels on polygons
Yeah you think it’s hard to do it in scrap mechanic but play plane crazy and try before making a statement like that for SM (you can only angle parts by 90° without extensive use of wedges wich means the weight is off-set) Also bulleid valve gear is better you get 6 beats with bulleid valve gear with 3 cylinder 5 are distinct and the 6th and the 1st happen at the same time boosting the volume and with the central input and twin-end output cylinders giving the bulleid pacific the most unique exhaust beat of any engine and it can’t be bad if it’s designed by O.V.S. bulleid
Great to hear someone who still and actually does have passion for what they're doing. That's hard to find in the UA-cam Universe.
Honestly I love mechanical systems and I love that you guys enjoy my nerdy concept videos!
i love mechanics its what pulled me into scrap mechanic
Pot8o_Penguin i saw you on scraps vid talking about floppy disks
Zone Breaker haha! 😂 Nice to see you again.
Who needs school when you've got kan
Talentedmajesticman your to right
Talentedmajesticman YEAH
Exactly
Ikr
And google
"The black arm provides the power to the system, and the white arm controls it."
Aidan Zigler I realized while editing that sounded kinda bad...
Aidan Zigler yes you did hear that right
lol
Same
Ор выше гор :D
I've looked at the Valve Gear Animation and I got hooked on steam and pneumatic engines... again:P
abradabk me too. I love these kinds of mechanical systems. So impressive
Please make a steamtrain
If you do tutorials again, and please do, please paint each independent piece of pipe (blocks connected to eachother and located in between 2 or more bearings), like you did at 3:37! It makes things so much easier to understand. Such a simple tweak can be a great visual aid!
Crazy how far this guy has gotten! And he hasn't changed one bit :)
I like the informativeness of this style of video, you should do more!
Favorite UA-camr

kAN you should make a olden day train VS a future train?!?!
There is another valve gear called Stephenson valve gear were all the reversing parts hidden underneath the boiler but a pain in the but to build but a fun challenge 😊
With a lot of engines the valve gear is inbetween the frames. E.g. GS&WR 101 Class. Every steam locomotive has valve gear.
Not all of them actually, down steam engines are actually turbine locomotives. Although most do use a kind of gear
@crazynachos4230 well anything that isn't conventional may not have gear but you get what I mean. Turbines made up a verybsmall minority.
I learned more in this video about mechanical pivot points, imma try this nextime on scrap mechanic
Bear in mind that a steam loco's valve gear doesn't only determine what direction the engine runs, but also the length of time steam is being admitted into the cylinder with each stroke back and forth.
You use full gear (front or back) to get started, and as the loco accelerates, you pull the valve gear back towards center to cut off the steam earlier and work more by expansion of the steam than by volume.

Dude this legit
This is amazingly informative and would love to see you teach more stuff on this game.
ken I'm glad you are making a steam train I'm a steam train fan
"This black arm powers the system, whereas this white arm just sorta acts as a *control* arm"- Ya don't say
I was just working on this kind of thing in scrap mechanic right before i clicked on the video! I love trains so very, very much, and I'd love to see you make a steam train!
Oh my gosh ive litterally been working on stuff like this for the last month or so
I've tried this but I cant get the piston to extend/retract at the right time. Any tips?
Please make a steam locomotive!
Yes thanks so much! I needed this

Don't forget Hackworth Valve gear being common in narrow gauge
Forgive me but i cant understand how exactly works the reverse engine, why change the direction moving that bar?
Love the video
Really intresting video, excellent work!

Time to make the big boy!!
You are finally making a train
this game could be more educational than a masters degree in mechanical engineering
Make a dumper car and a car hauler car for the steam engine
If you do the steam train use thruster pistons ( u know use a thruster for the pushmotion of the piston) u get the extra steam engin kinda noise :)
Also bridgecrane
Could be interesting having a steam locomotive in Scrap Mechanic.
How did you have the logic gates set and connected?
You should make trains that are powered by different engines
Hi
Well hi again
wait did i hear this correctly the white arm controls while the black one does all the work (3:40)
kan i hope this was not intended
Šømē Øñê he did that so it was easier to see what he was looking at..
How'd you get the piston to go at the right time? Can you do a video how you can do a logic gate repeater?
Yes do a steam train!
Lookin Nice! :)
3:37, the Eccentric, 3:43, Drive Rod, 3:49, reverser, 6:35, you are talking about British and German trains, also, look up the American 4-4-0 locomotive, it is easier because it has valve gear in between the drivers
hey kan what are u gonna stream today? tell me plz! ♥♥♥
continuing the cargoplane?
The reverser controls the direction of travel you would put it on 100 when starting to move when over 10 mph or kph tou would lover it to get faster speeds if you dont understand have a look on the internet
How do you attach bearings like that? I cannot for the life of me seem to get it
TRAINS!!!!!!!!!!!!!!!!!!!!! YEEEEEESSSSSSSSSSS!!!!!!!!!!!!!!!!!!!
All steam engiens had valve gear. Some had the valve mechanism between the wheels attached to the axles. Some had the outside with the pistoms and some had pistons and valves on the axles. (Between the wheels)
Raaabon Laaanon yes the stevenson method has the valve gear between the axles. What I like about this method is it is completely external to the chassis of the train
Definitely do it
Also some steam engines had levers for reversong. Not all had hamdwheels
Raaabon Laaanon True enough I was refering to the one in the animation linked
kAN Gaming could we possibly make a steam loco together?
I think we could make a pretty good one
Great... I finally figured out how to make this and I start doing my details last night and kAN uploads this today... Great... Ima be called out about copying... Thanks kAN...
At least they are quite different...
Have fun m8
Chuga chuga chuga chuga Choo Choo!

Yes I looked at the stevensons as well but I thought this one was much cooler. I agree its not perfect but I thought it was pretty close for Scrap Mechanic :D
kAN Gaming oh i agree completely, it works really well for the limits in scrap mechanic, and looks a lot better in motion in stephensons!
The steam trains in Queensland have the Walschaerts drive gear
I'm attempting to make a vanilla train, got the "vanilla train wheels" going but... it can only run on motor :(
How many times have I watched this....?
a Victorian Railways R Class has a Walschaerts Gear on it, kAN i'd suggest looking at its design of the engine itself.
The control arm pushes the valve, not the wheels. The piston on the other side of the locomotive pushes the wheels past dead center.
i made a valve gear too its 2 piston setup it goes up and back
OMG it had been a long time when I saw your vids
Actually what it does is control what side the steam gets injected into, to control direction
0:40 is like r1 crossplane engine so is like an real engine
Kan: It looks kind complicated
Me: I perfectly understand it. How is this complicated?
How do you connect two bearings?
Can u live stream building an excavator and make a
Dump truck for it and put it on the workshop
Yes I want you too make a Steam Train
Please Kan can u test that coloured mechanical engine test on rails?
Id love to see a steam train from you
Who needs to reverse when we got turn-tables and loop-around and stuff
XXD
i am quite intrested in train trains, but ive never known how the reversing rod worked untell today. (feb. 13 2017)
Could you put it on the workshop anyway? Maybe it will work- who knows. I wanna see if I can make a steam engine with that, and I would give you credit if I put it on the workshop. Also, I've made a succesful 2-directional train with a 3-piston pipe system, so could you tell me what you think of it if I share it with you?
Give the mechanism to ScrapMan for his steampunk suspended mountain base!
Ngl a hackworth valve gear would be cool
Yes i know the video is 3 years ago
yes make a steam train :)
i think you should make a train and i know either durf or lordpain has train wheels and train tracks in one of their mods which would be more realistic than default wheels on polygons
I probably should look into what wheels are available because I would like to have a better train setup than the default wheels.
it is the modpack by durf that adds the train wheels and tracks
You should make an act train with that
I left it open!!
1:01 there is another
Could we possibly do that kAN?
Can you make the baker valeve one
Hey!!!i love your videos and would love to get on one of your live streams have a nice day!!!
Yea, make a steamtrain!
To squeeze it on the car You can just use elecetric/gas motor as... starter.
That yellow arm is the reverser
And ive made that valve gear work smoothly.
i was trynna make one in my train, didn’t work, waaay too big
DO IT!!! NO BALLS!!!!
JK, but seriously, you should make an awesome train =)
How ya doing kan what's up
Multiplayer Monday content?
Yeah you think it’s hard to do it in scrap mechanic but play plane crazy and try before making a statement like that for SM (you can only angle parts by 90° without extensive use of wedges wich means the weight is off-set)
Also bulleid valve gear is better you get 6 beats with bulleid valve gear with 3 cylinder 5 are distinct and the 6th and the 1st happen at the same time boosting the volume and with the central input and twin-end output cylinders giving the bulleid pacific the most unique exhaust beat of any engine and it can’t be bad if it’s designed by O.V.S. bulleid
Make a steampunk steam train!
I mean, the mechanism is bulky, why not use it where it would fit
When you trn it on one time you trn it on it goes forud and the 2 time you trn it on it goes back wort
yes, i do have a Kangineering degree
Kan next stream make a car that is crashable car
That's impossible tho.....
Jovi Summer P no its not
Making a car 🚙 that crashes works
