5:23 notice how the suspension piece isn't pushing the follower down fast enough to maintain contact with the cam lobe. In an internal combustion engine, that's what they call "valve float". It allows the piston to remain unsealed longer than it should and is a factor to n maximum engine speed. Before engines were mostly computer-controlled and could limit their own max rpm, this would be what would happen if a driver pushed to hard past the "red line" (a marking on the tachometer indicating max sensible operating speed) and it could damage the engine.
Yeah I can here to say the same thing essentially. That he is floating valves and a stiffer spring should help with that so he can Rev it out at a higher rpm.
Stiffer spring might actually not help; in real life physics it would, but one thing that seems to send SM physics off the deep end is competing lateral and rotational impact forces. More contact with the wheel surface at a sharper impact force might act counterintuitively within the system. It'd be interesting to see him play with it and find out.
And chains are 100 times better because there more reliable and you don't have to rip your entire engine apart to change a belt than take like a few things off like the front of any small block chevy. all it is the balancer and water pump then the cover that goes over the cam gear and the crank gear and the chain. so you usually will never have to be in there but when metal gets hot bad things happen and the chain could snap or just grind the teeth off the crank or cam gear. but that's after a load of miles of abuse and basically beating on it till it blows up its entire life 👍
I know it will be really hard, but try "making a real car" (with an engine with this type of piston, real turning, breaks and maybe gears). the car would be big but it would be fun series. Starting with just the basic to fancy doors automatic gears, sensor spoilers and many more. Not only it will be fun but also you can use the different parts in multiplayer Monday in maybe an assemble a car and race type video. love your contents scrapman!
i think this is more of a khan type video, scrapman focuses on the more simple, yet fun contraptions, kan makes more complex and realistic mechanisms, although his videos are a little less... eye grabing per se.
@@a_arthur1293 I think you make a great point, Khan makes highly professional Scrap Mechanic grade builds, but doesnt execute the...."advertising" for his builds very well. But I love his builds too!
1:40 the goal of the wedge cam and follower is to increase the push force using the angle of the wedge. It is easier to push the cam than the follow because the angle with the ground is less than 45°. Pushing the cam down would be much harder, and possibly impossible. This is quite useful when you want to control the position of a part without having the ability to push back the machanism.
You should try the VZ-1 Pawnee or a Tailsitter plane. The VZ-1 was intended to be a hover platform for snipers or lookouts which required little control and allowed them to basically just sit mid-air. As for the Tailsitter, bit self explanatory - a plan that could take off (and land) vertically
@ScrapMan , Not all ideas are winners, but this one knocked it out of the park. Fantastic idea, explanation, and execution. This video could be in a science/math class in my opinion.
I'm commenting late because I watched this with my roommate's kid and just swung back around to share my thoughts. What you did here qualifies as a science lesson with an artistic touch. It's stuff like this which advises me to share you amongst the children I part-time Uncle. Thanks for being high quality, clean, and informative. I notice.
Either that or bags for a car but on a smaller scale so it won't have to be huge and have fully adjustable hight rather than the pistons only having full extension or full compression
That dragon at the end gives me some strong "Magic Carpet" vibes. An old video game where you were fighting creatures, like those worm-like dragons on a flying Magic Carpet, hence the name. The flight patterns where just as wavy and segmented as on this contraption.
Hey, ScrapMan! Despite Debuting it in December of last year I only decided to check out Catarinth today because I was wondering what the new outro song was and let me say... if I could go back in time, I would slap myself for such Blasphemy. I don't remember when I started consistently watching your content, but it was some time around 2 years ago and finding your channel has changed my routine and choice in games a lot! Every morning I watch that 7am upload during breakfast and I never would have started playing TrailMakers or Scrap Mechanic without seeing you play them. I've never been able to build anything as cool as you have, but I've had an absolute blast playing them! Thanks for all the work you put into your content and now Music! I will stick with your channel forever!
dude literally taught us how a carb intake piston works, in the most simple of ways. ngl im literally going to show these videos to physics teachers because scrap mechanic could very well be a good teaching tool
also asside from the initial cost of the game which im pretty sure a schools stem programs could cover its a costless way to teach kids about rotational vs linear motion and how to transfer said motions
You should try to make a tensegrity structure in a game with rope physics, or something along those lines. Maybe instruments of destruction could work?
A wedge cam/follower can move linear motion to some other angle, in a confined space, and do it very precisely. Also, depending on the shape of the wedge surface, you can change the follower pattern.
we're doing a project on cams and followers in my engineering class. theres this box and you can do basically anything you want with it, but you have to design something to put on top that will use a cam to move it. for my box im doing a plane on top and having the cam drive the propeller. i might post a video about it when its complete.
I love how you make these videos both super entertaining and fun to watch while somehow still being educational, you would make a great teacher. Which you basically are. Keep it up !
I hope the translation is effective ... This series is truly superb, gorgeous! Not only is it incredibly entertaining, but it also allows you to learn (or deepen) very interesting concepts and knowledge ... For what it's worth, you will always have my thumb up and I hope it can be a fixture (not necessarily unique, but constant in your content). Keep it up as always Scrapman!
With multiple suspensions, they will not freak out if you have them on different strengths. Also, try to use 2 bearings connected to the part holding the cam at different height points on adjacent sides or the same side (but not on opposing sides of the same block, or it will allow it to rotate), to act like a different creation while also not causing as much lag as being a different creation. Also, show this to Kan, he tried to make an explosion-powered engine, and this could really help with that goal of his.
In a way what happens here when you spin the cam too fast is a thing that can happen in an ICE as well. It is called 'valve float' and it's a condition when the valve does not have enough time to close before it's pushed back up by the cam. Same cause too, over-speeding. Also that wedge follower is a way to change direction and essentially ratio of movement, not one type into another. By changing the angle of the wedge the follower can move faster or slower than the initial force, or be programmed for some more complex motion by making a stepped or a 'multi-tier' wedge. Take a look at a wood lathe duplicator and think of the pattern as a fancy wedge :) And finally, to make springs not freak out, set one slightly stiffer than the other, that way they will compress one after another instead of 'fighting' each other.
I am glad I stuck it out. The first part of the video was like, meh stuff I already know and a bit boring but wave mechanism was stupidly satisfyingly to watch.
Badass video scrap man! Reminds me of how I played this game bringing real life mechanisms to the game building around the limitations of the building system in scrap mechanic tons of fun to watch as you work through these keep it up!!! 👍 🔥
Can are used as synchronization tools… there are many ways to convert rotary to linear motion, but sometimes you need actions to occur simultaneously. To achieve this it is usually easier to drive all the needed components from the same energy source rather than have two motion sources that then have to be aligned properly
Something interesting is that Internal combustion engine technology has evolved past the need for a timing camshaft with Freevalve. Timing cams are an insanely large source of drag in an engine so getting rid of them frees up a lot of potential power and efficiency.
I'm in agreement with some of the below comments. You should absolutely try to make an "Archimedes screw tank". It would probably be easier in Trailmakers than Scrap mechanic, but getting something like that to actually work in either is probably worth it for the challenge alone.
I remember in recent video where scrapman was viewing a video on the pin and slot video where SM clicked on the application and by mistake clicked the cam option n was like wtf is this 🤣🤣 and now a video. Love it
2:30 not to be the gearhead nerd here but that exact setup is an in line 4 cylinder (can be configured similarly known as a boxer engine to reduce vibration/sounds/heat and is slightly more efficient) and the configuration on the valves is called a DOHC or dual overhead cam.
I would imagine using a timed cam and follower as an ornithopter engine would make flying much smoother as well as have a consistent flight that wouldn't bob as much
The cam and follower isn't just for converting rotary motion into linear motion it's also for timing which was part of the reason it was used in combustion engines and that's why there are wedge cam and followers as different angles allowed for different speeds of things to open and close
Could you not use this system for a wheel suspension so you would have a controllable height of your vehicle you could then have a new suspension for your vehicle in the game. It would give you more control with the height
Scrap man, later today I’m going to release two creations that will be very helpful to you. First: the fast and extreme controllers. Blueprint-edited controllers with fast and ridiculous speeds, respectively. Second: the Vehicle Recovery System. This lets you exit the world border (infinite falling), but as long as you stay in your car it can return you back to the world.
Scrapman. looks like you found a niche that will keep you relevant past scrap mechanic and trail makers relevancy. teaching history and mechanics. I really like your failed inventions series so far and the comedy behind that ensues.
hi scrapman , i would love to see you replicate the insane 1000000 rounds per minute "metal storm" experimental gun . thanks for keeping up the great content !
Hey, Scrapman: you should see the cutaway of a Pratt & Whitney R-2800 Double Wasp radial engine, it’s pretty crazy with how the pistons and counter weight runs inside of it to drive the propeller shaft. Would be awesome to recreate it. Another would be the engine used by the Bf-109 because it had either a 20mm or 30mm cannon (depending on airframe model) in the middle of the prop hub.
The left cam with the wedge piece is like a valve, precisely like the video at the beginning. You want it to open only to introduce a fuel air ratio, or to vent the exhaust gas. But closed so it can retain the pressure of the combustion. As somebody said earlier, to fast you get valve float, when it went ape and stayed basically open. The design on the right is more of piston momentum, a constant moving stroke. To compress the fuel in the chamber for combustion and also a second stroke to vent the exhaust. I would love to see if it's possible to model a 4 cylinder motor using your tire methods, could the game handle that intricacy? Especially trying to time the valves between the piston strokes.....that is a hell of a challenge.
8:41 I would love to see a smaller design of this to make basically bags in scrap mechanic on a vehicle would be pretty cool and you could make them on all separate buttons like pistons but a lot more smoother and can sit at a specific point rather than fully extended or fully compressed so you basically built a low rider that doesn't hop but can 3wheel and everything that lowriders do 👍 Also this is a really good explanation of how a cam and valve setup works in a engine of basically any type
Cams can open the valves of an engine several times a second. There are several F1 and motoguzzi engines capable of 20,000rpm at the crankshaft, which translates to even more RPM at the camshaft
I think a good idea for MultiMon would be a sort of “junkyard zombie survival” where you have the junkyard challenge, but you have to build a vehicle to survive waves of bots
Had a question then answered it while I was typing it lol. This is a really cool mechanic and I'd like to see you apply it to a creation. Like an over engineered walker.
Just am fyi if you’re going for the camshaft in an engine style, your beginning models are more realistic as you need them not hold the follower open for a duration to give the engine time to compress the fuel air mixture and ignite it, it wouldn’t be able to do this with the follower (valves) slightly open as there would be no compression it would just push the fuel air mixture through either the exhaust and/or back through the intake
We’re here just watching Scrapman slide right into being an educational channel and I’m down! Excited to see if any of the mechanical things he’s learning will make it into Multiplayer Monday’s to give him an leg up on the competition!
While the second design is nice and smooth the first one actually has a lot of practical use irl. In the instant of an engine they’re attached to the fuel and exhaust values inside the cylinders. The engine lets in fuel, then closes the valves and compresses the vapors. A spark ignites the fuel and the following boom forces the piston down making the power to turn the crankshaft, then the exhaust valve opens and the piston moves up pushing out the spent fuel. If it was the smooth sin. wave it wouldn’t line up properly with the steps of internal combustion. Fuel and exhaust would mix together, you couldn’t get proper compression and it would probably destroy the whole vehicle. However, these valves couldn’t use logic gates or electronic timers so the cam did that job, since everything is constantly rotating in the engine it would push the valve open for a short amount of time then take awhile to rotate back around to do it again in sync with the other moving parts of the engine So while the wave is pretty it’s not always the right motion for the job Also helps that irl can do custom smooth shapes better then a building grid
Scrap man big fan here love your vids, keep them up. anyway can you try to make a walker using this concept like a strandbeest using the cam follower? i would love to see that
Mack truck Etech engines with power leash compression braking uses an extra lobe on the other side of the exhaust cam to allow for compression braking, and is activated hydraulically by closing up the clearance in the valve lash by use of engine oil pressure.
Its interesting to see you reframe the new idea inside the realms of scrap mechanic physics, to essentially turn it into a different thing, but a kinda new one. In the real world, we have access to the gradient of positions, but in scrap mechanic apparently not, so it makes sense... but, in the real world a cam-as-linear-actuator makes no sense given other options... Either way, great re-use of the idea.
The wedge in the wedge cam can be shaped so that the follower can move at a different rate depending on the wedges position eg you can have the follower move a little bit for the first 80 percent of its travel, and a lot in the last 20 percent
I’m a teen learning automotive. And you would want the first one/ the tire with the add block because it lets open the valve which is what that build is for more control and not like a wave because in a combustion engine it would let fuel or air in to the engine which could lead to no air compression. I thought I could tell you to help you.
I could see a mechanism like this providing the vertical adjustment for a tank turret. It should also be difficult to back-drive so it shouldn't droop.
You got the piston thing backwards. You said it was like the cam and follower converting rotary motion into linear motion, but it is actually the other way around with the combustion causing linear motion of the piston which drives the rotary motion of the shaft
I built an ender dragon in high school that had wings that moved up and down with the use of cams. They are really interesting mechanism that once properly understood, an be used in a wide variety of applications. If anyone has played with the minecraft create mod, the motion of the plate press has similar motion the what scrapman made.
Hey Scrapman. Since you are practicing cams, maybe also try something called a cam or thrust device. Its the mechanism that allows a click pen to work.

@@flyingmunk8956 I presume stiffer springs would add more load to the engine limiting power ...
Thank you for the information. I was wondering what it was called.
Dang it I was about to comment that
This is why when a timing belt in your engine snaps bad things happen. Although most cars now use a timing chain :D
Hi kAN
And chains are 100 times better because there more reliable and you don't have to rip your entire engine apart to change a belt than take like a few things off like the front of any small block chevy.
all it is the balancer and water pump then the cover that goes over the cam gear and the crank gear and the chain.
so you usually will never have to be in there but when metal gets hot bad things happen and the chain could snap or just grind the teeth off the crank or cam gear.
but that's after a load of miles of abuse and basically beating on it till it blows up its entire life 👍
thats cool :>
hi KAN Gaming.
Sometimes I forget kAN is an actual car mechanic
Hi Scrapman, have you tried making the corkscrew tank? Basically a tank but the treads are screws - I think that would be awesome. Thanks as always!
that will be fun
It would be hard but possible
how would you even make that move? irl the screw digs into the ground and pushes it but in scrap mechanic its not gonna work
That would be cool but doesn’t it need to dig into the ground to gain traction?
Im not sure if this would be possible in scrap mechanic because the tank works by digging into the bottom
I know it will be really hard, but try "making a real car" (with an engine with this type of piston, real turning, breaks and maybe gears). the car would be big but it would be fun series.

@@Nevir202 yup!
Its a reverse pulley
It's also used in machinery to make adjusting the timing of what the follower is engaging / disengaging easier to adjust.
Scrapman, you should piece together all the weird mechanisms together to power a car. Seems like a chaotic challenge you might enjoy.
Haha yes
Of making a train
You should try the VZ-1 Pawnee or a Tailsitter plane.
The VZ-1 was intended to be a hover platform for snipers or lookouts which required little control and allowed them to basically just sit mid-air. As for the Tailsitter, bit self explanatory - a plan that could take off (and land) vertically
Scrapman could try making a clock escapement for a pendulum clock. I've made one in Scrap mechanic myself, so I can guarantee that it works there.
We could technically just call this "Scrapman teches himself and his viewers engineering"
Scrapman straight up teaching us mechanical engineering
Yeah
and he doesnt even have a mechanical engineering degree
I like it!
5:13 and this is what we call valve float, The follower doesn’t go all the way back down with the shape of the cam if the cam rotates too fast
@ScrapMan
, Not all ideas are winners, but this one knocked it out of the park. Fantastic idea, explanation, and execution. This video could be in a science/math class in my opinion.
All my life I wondered why it was called a "cam shaft" and now I know thanks scrapman
I found this channel recently, and I'm addicted. I love all the multiplayer shenanigans, but I've also really learned a lot. Teach us more! :)
That's a massive user name
Suggestion: try to make a train that uses this mechanism move (like how an irl train works)

Either that or bags for a car but on a smaller scale so it won't have to be huge and have fully adjustable hight rather than the pistons only having full extension or full compression
Glad to have you back, man.
The wedge one is used to convert horizontal liner motion to vertical liner motion. But good vid overall.

Hey scrapman!
Try making a walker out of this concept.
dude it would be like level 2 strandbeest in scrap mechanic
Use you cam and follower method with your explosive pistons with an indestructible block mod and make an actual engine
this opens up so many types of machine possibilitys.
LOL, "I talk into my Cam and talk to my followers." XD That's GREAT!

Cams can open the valves of an engine several times a second. There are several F1 and motoguzzi engines capable of 20,000rpm at the crankshaft, which translates to even more RPM at the camshaft
This just unlock more limits into builds and creativity in future build for people and urself
This seems very useful for various contraptions! I'll be sure to use it when I see the chance
If Kan is train channel now, scrap man is a reversing engineering channel.
I think a good idea for MultiMon would be a sort of “junkyard zombie survival” where you have the junkyard challenge, but you have to build a vehicle to survive waves of bots
Had a question then answered it while I was typing it lol. This is a really cool mechanic and I'd like to see you apply it to a creation. Like an over engineered walker.
Just am fyi if you’re going for the camshaft in an engine style, your beginning models are more realistic as you need them not hold the follower open for a duration to give the engine time to compress the fuel air mixture and ignite it, it wouldn’t be able to do this with the follower (valves) slightly open as there would be no compression it would just push the fuel air mixture through either the exhaust and/or back through the intake
We’re here just watching Scrapman slide right into being an educational channel and I’m down! Excited to see if any of the mechanical things he’s learning will make it into Multiplayer Monday’s to give him an leg up on the competition!
Scrapman: *uploads*
Me: scrap mechanic? Nah...
Also me: *reads thumbnail and title*
Also also me: YES FINALLY! SCRAP MECHANIC
While the second design is nice and smooth the first one actually has a lot of practical use irl. In the instant of an engine they’re attached to the fuel and exhaust values inside the cylinders.
The engine lets in fuel, then closes the valves and compresses the vapors. A spark ignites the fuel and the following boom forces the piston down making the power to turn the crankshaft, then the exhaust valve opens and the piston moves up pushing out the spent fuel.
If it was the smooth sin. wave it wouldn’t line up properly with the steps of internal combustion. Fuel and exhaust would mix together, you couldn’t get proper compression and it would probably destroy the whole vehicle.
However, these valves couldn’t use logic gates or electronic timers so the cam did that job, since everything is constantly rotating in the engine it would push the valve open for a short amount of time then take awhile to rotate back around to do it again in sync with the other moving parts of the engine
So while the wave is pretty it’s not always the right motion for the job
Also helps that irl can do custom smooth shapes better then a building grid
The wedge cam is used in braking systems, mainly for heavy road transport.
You ask why it's used, it is to do with mechanical advantage.
Scrap man big fan here love your vids, keep them up.
anyway can you try to make a walker using this concept like a strandbeest using the cam follower? i would love to see that
pls like
Scrapman here s an idea for a video .
There is an desruction mod that has good desruction physics. You could check out the mod.
Link?
Mack truck Etech engines with power leash compression braking uses an extra lobe on the other side of the exhaust cam to allow for compression braking, and is activated hydraulically by closing up the clearance in the valve lash by use of engine oil pressure.
Its interesting to see you reframe the new idea inside the realms of scrap mechanic physics, to essentially turn it into a different thing, but a kinda new one. In the real world, we have access to the gradient of positions, but in scrap mechanic apparently not, so it makes sense... but, in the real world a cam-as-linear-actuator makes no sense given other options... Either way, great re-use of the idea.
The wedge in the wedge cam can be shaped so that the follower can move at a different rate depending on the wedges position eg you can have the follower move a little bit for the first 80 percent of its travel, and a lot in the last 20 percent
I’m a teen learning automotive. And you would want the first one/ the tire with the add block because it lets open the valve which is what that build is for more control and not like a wave because in a combustion engine it would let fuel or air in to the engine which could lead to no air compression. I thought I could tell you to help you.
as a car enthusiast, it would be cool if you made a whole combustion engine in scrap mechanic.
using this, u can make a sound wave demonstration machine, like the once that demontrate a sine wave and a pressure wave (sound wave)
I could see a mechanism like this providing the vertical adjustment for a tank turret. It should also be difficult to back-drive so it shouldn't droop.
Hey the detonation in the cylinder is where the power originates. So it's linear motion being converted to rotational motion.
with this you could make GBC (Great Ball Contraption!) it would be nice to see such thing in scrap mechanic
You got the piston thing backwards. You said it was like the cam and follower converting rotary motion into linear motion, but it is actually the other way around with the combustion causing linear motion of the piston which drives the rotary motion of the shaft
5:18 Congratulations, you have replicated valve float!
I built an ender dragon in high school that had wings that moved up and down with the use of cams. They are really interesting mechanism that once properly understood, an be used in a wide variety of applications.
If anyone has played with the minecraft create mod, the motion of the plate press has similar motion the what scrapman made.
Very cool video! This will have tons of scrap mechanic uses!
8:05 It's similar to how they make nano measuring devices.
Hey Scrapman. Since you are practicing cams, maybe also try something called a cam or thrust device. Its the mechanism that allows a click pen to work.
