- Welcome to another episode of Scrap Mechanic! Today I am recreating this strange mechanism that seems to be some kind of radial piston mechanism, but it's not as straight forward as the animation makes it seem.

The reason yours doesnt work the same way as the animation is because all of the pink pieces are supposed to be rigidly connected, thats why they're the same color. It is done by a rod running through the axis of the bearing, which is not easily accomplishable in scrap mechanic.
that's what i was guessing, interesting to see that it can work similarly though.
the blue part is hollow and the piece goes through the middle to keep it stable
Yea its a radial engine crank with rods and pistons not a bunch of free spinning bearings the other problem is the power should be coming from the linear actuations of the pistons and not the rotation of the crank or you would have a radial compressor and not an engine
I was wondering the same. It's fun to see him work around it hehehe nice vid
@@general.catallion_8054 Yes and no the difference is one is an engine that could be used as a compressor or a linear actuator EX its meant to take a linear force and turn it into a rotational force but could do either where the other being the Trammel of Archimedes is intended to take a rotation force and turn it into a linear actuation and while it hypothetically could do everything the other one can it would be a lot harder to do being a completely different mechanism that was made to do only one thing but its able to do that one thing with substantially less moving parts
One more thing. I'm really amazed scrapman forgot he is simulating pistons which slides through pipes which, inherently, are guides themselves.
Yes
The violet/pink part in the middle is one singular rigid part. You should have connected them together with pistons or suspensions to simulate that.
Scrapman has this amazing ability to add so much life and interest to his videos! He only works from a few constant formulas but every video has it's own identity, I was led to this channel by kan and I'm so glad I found it. I've smiled too much at these videos! Your comedic timing is perfection, Scrapman!
Well described

You actually built it wrong. The pink parts are supposed to be one part with the place where the bearing is being threaded through the piston's rod, so it would be more realistic if you were to connect them with a piston so that they behave as they would IRL.
I'm surprised it worked at all the way he built it.
The reason that your radial piston isn't working the same as the diagram: Your "Pink/Purple" cam isn't fixed. Notice that center piece doesn't flex. It isn't 3 pieces that rotate independent of each other.
You could fix this by using pistons (which other objects just pass through, I'm sure you're aware), to make that center component "All one piece"
its X engine
i think that its supposed to be creating rotation from the radial piston movement RATHER than the radial movement from rotation.
looking at the crankshaft like structure in the middle it reminds me more of an engine design
Yes. Clearly the piston heads are where power generation is supposed to be 🤣
Thats definetly it because the Pistons have the sealing Rings and the shafts have rivots to output the power
@@Maxikxng splines*
@@Maxikxng That really doesn't tell you which side is powered. This could just as well be a piston compressor.
The mechanism is meant to have the linear motions of the pistons driving the mechanism (like a combustion engine piston). If you had the ability to control them, you would have control over the piston sequence direction... and in turn whether or not the pink pieces are in alignment or not. You were figuring this all out from the other end of the power train, which honestly is kind of impressive.
I think the rotating pieces above and below each piston block would be connected with something like a through pin instead of a free bearing on top and bottom. That way it actually applies force to the piston arm itself and ensures they rotate together.
Also yeah, you could have connected the pink bits with pistons which have no collision
You should do a revisions video of various projects that didn't quite work right because it kinda hurts when you don't see the thing going wrong.
Everything in pink is a single solid piece, it just fits through the blue parts.
The word you're looking for scrapman is "crankshaft", all the pink/purple pieces are supposed to be one solid part.
The pink rods are supposed to be connected rigidly together. It should then work.
i know it's more difficult in scrap mechanic, but most likely on the youtube animation the purple segments are all attached to each other with a rods through the piston rods. that way they are one solid segment and always keep in line
10:21 that is because the pink section is a hole piece. You can not make it without using none colidable objects like pisten or suspension
you could make it without piston or suspension, it would just have to be bigger
Watching this makes my mechanical engineer heart hurt
Idea: torsion bar suspension
Its bassicaly the suspension they use on tanks. Looks satisfying
*I wonder if you could use some of these mechanisms for some of your multiplayer puzzles? That would be pretty cool!*
Why was this all in bold though????
@@Egerit100 Well you saw it didn't ya? 😉
@@WD-1477 fair
Welcome back Scrap!
It's been a while since I've seen you. Love the vid and I hope your renovations and move is going well
Yall should play tag with the portal mod and destroy the other people
Agree
In the original, the pink pieces are held in orientation with each other by the shafts going through the pistons. They're not separate pieces the way your bearing version is.
It's fun to see more and more stuffs have been put on the shelf. :D
A new day of asking Scrapman to build the Antikythera Mechanism.
All the pink purple parts need to be connected you can use pistons to connect it also the power needs to come from the pistons not the drive line
good as always
The "thing" here is, that the bottom and the top pink parts are usually connected with a joint on a bearing with the middle pink part, through the pistons.
The real Question is: Can you bring it to life with explosivs?
All the pink is essentially a solid crank in the animation.
love the new background 👍
In the animation, the cranks have solid pins going through the pistons and connecting them together, they aren't two seperate bearings
basically what made it not work is because its supposed to be more of crank shaft like item thats attached at the center point on each end by a bridge to the rotating point creating the order of the pistons that are jointed to the crank shaft thats allowing the pistons (if this was used as an engine configuration) to all produce power to a rotating point every 90 degrees meaning that if it was to put in an engine with 8 pistons but 4 rods in this configuration you would want every other set of 4 pistons you would want to offset the power stroke of the piston by 45 degrees and so from that you have smoother power and more of it basically creating a 4 piston segment radial configuration that you have bigger bore pistons with
What scrap man missed was that the pink piece was one solid piece effectively the green pistons had a hole drilled out in the center of it so the pistons wrapped around the pink instead of 3 separate rotating pink pieces
its actually suprising how realistic scrap mechanic can be even though it is a game it does have its bugs though
Excellent work on this mechanism!
I wonder if you could use pistons and controllers to go linear->rotational like in an engine, or if scrap mechanic can't do those sort of timings
11:00 in the video the pink is one solid crankshaft like in an engine so i goes through the middle of the piston rods and stays connected its not three seperate pieces like you have it, however locking it with a controller would provide the same result
The radial engine is actually used in a ww2 planes like the p-51 and etc
@0:52 -- The Trammel of Archimedes was just shown on Grand Illusions (3 days ago) in Tim's video titled *"Tim Travels Back To 1986"*
I can't say for certain but to me that looks like an engine type of mechanism, and if it is then the power is actually coming from the piston ends themselves, the yellow parts
Scrapman; the inventor of the Radial Pizza Mechanism.
oooh new background i like it
While everyone commented about the pink segments being one part, has no one ever thought about the fact that a piston engine is usually powered by the pistons, not powering the pistons? That would probably fix the problem as well
everyone commented that too
The pink piece in the animation is all one part. They have a rod connecting them that goes through each piston shaft. This also allows you to only to to power one baring. however, this is probably all impossible on scrap mechanic. Your probably as close as you can get really.
It is possible if you use the fact that in-game pistons and suspensions don't have collisions.
Aka you could connect the pink 3,5,3 parts with them to simulate a solid piece.
That's something that is used in some SM piston engines to make a crankshaft.
In the animation the animation there are pins and bushings that hold the pjnk section in free spinning pairs
Another interesting thing you could try is powering the pistons instead. Might be hard to get it from being locked in top dead center, but would be cool if you found a way to get it working.
you should use a sensor/thruster combo to power the pistons more like how this would be functioning as an engine :D
He got the use of this mechanism completely wrong but like always he turned it into a very interesting and entertaining video!
you guys do understand that in scrap mechanic you can use pistons to connect the pink pieces and make them a rigid Crank then the mechanism would work due to the pistons making that pink part a solid part
The Piston design is probably made for some form of engine like maybe a plane or an interesting car design
Wonder if the guides are needed when the pinks are synced or made rigid to eachother
this thing doesn't work because of 2 things: 1. that's what lots of ppl said already - purple part is basically a one single piece of metal. 2. this "mechanism" is not a mechanism, its a part of X-tipe engine, that is actually exist, which means pistons aren't free part, they incased inside the celinders of the engine, also it means that the sorce of power here are the pistons themself.
I found something you should build in Trailmakers, it´s a experimental navy hydrofoil called USS Plainview or AGEH-1. You are the only person who can give it back it´s glory.
I was going to say this is a lot like a much earlier creation of yours than the trammel but after digging around a little, it turns out I was thinking of one of kAN's videos from the early days of pistons in scrap mechanic (from five years !!!! ago). Its title is "Radial Engine and Piston Powered Cars! (Scrap Mechanic #183)" and the engine has an interesting 4 piston single plane design. A second take on the mechnism in today's video where piston clippnig is used to turn a common central shaft might be able to get the motion to match the example image. The limitations of scrap mechanic's surface mount bearings and lack of through-pin/wrist-pin/journal-conrod devices makes it not quite possible to fully match otherwise.
I think what is missing is that the pink is all solid. Like suspension should have been used to keep the purple completely locked. Otherwise the pistons couldn't power the device. This would only work with the shaft being powered which is not how an engine works.
The studio looks cool!
Naaa I don’t think cause it’s just a black background
Nothing epcial
But what you should’ve said is the animation is “SICK”!
Idk how he does it but it’s a master piece
And scarps replica was in sync with the animation it’s cool
The piston is the power input and the geared cranks are the power output
something to try that might be interesting, as these are pistons.. they are supposed to be the power source, adding a short duration "thruster" ont he end of each piston with a sensor... to have the thruster to fire a short burst, at the begining of each stroke.. ie when the piston reaches its full length, it trips a sensor, that activates a thruster to stat it moving in the other direction... then have all 4 pistons providing the power, instead of the top/bottom. might be interesting...
You should've used piston to keep the pink pieces rigid to make a similar working system as what's would be used in the animation to the pink pieces to be rigid
I just realized this is in the new house congratulations
the pistons would normally be in cylinders that keep them aligned and the power is supposed to come from the pistons, not the crank.
my comment is kinda late but today I see a suspension piece and an SM mug, some stuff in plastic that I can't make out, a couple more really cool mugs, and a cool dragon thing. :D
youre supposed to connect the pink pieces, as im sure others have said, you could do it with pistons
That's frustrating Scrap Man !
At 5 am...
*FRICKIN GIGACHAD*
Don't forget, the applied force in the diagram is supposed to come from the piston head and not the drive shaft!
See your in a new place, eh! Looks cool, seems like theres some of ScrapMan history behind you, as well as some other stuff. Cool, I honestly like it more than the green-screen gear background in all of your previous videos!
ScrapMan, the self taught engineer
on what's supposed to be piston heads you could have used wedges to make it more round looking.
Never thought I would be this fascinated by a pizza engine
hey scrap man try making the rotodyne in trailmakers its another autogyro that also has jets on the tips of the rotor similar to the triebflugel
Scrapman needs to recreate the Convair F2Y Sea Dart.
as an actual engineer, all I can imagine is how terrible this would be, theres a reason your internal combustion engines are balanced a certain way, I suppose of this things RPM is really low it be alright
Also, the trial of archimedes has only one source of rotation, while the other has two.
i think all bearings need to be powered to simulate having rigid connections for the pink parts. the only unpowered bearings would be the ones connecting the purple to the pink.
or just connect the pink parts with pistons
His mug's now got a suspension! I swear i'm gonna spend 10% of my time on youtube analyzing his backround from now on lol
You should try brick rigs(if you haven't already) its a physics simulation game, and you can create a lot of real life working mechanisms and many other things with high accuracy
It does have a bit of a learning curve to it, and the occasional bugs
You have a very epic guitar on your wall 😍
Your right
why only 40 likes so far cmon this guy is amazing we can do better than 40
ok, 2.6k likes
@@vibaj16 not good enough should be 1 billion
you mentioned things that wouldn't be possible and i thought of some kind of proton collider. It made me wonder if spud gun bullets collide?
they don't
I think the bearings in the middle need to be powered to rotate in reverse direction
You should try to make the doroni h1 eVTOL in trailmakers
its because the pink parts is connected by a pin passing trough a bearing on the green parts making pink a solid part
I like the background
The power is supposed to come from the pistons. This is the internals of an engine, the middle part is a crank shaft/output. Also, what everyone else said.
the purple parts(top and bottom) needs to be built in the same orientation
it reminds me of the basic engine in traimakers.
hay scarpman i want you to make this in trailmakers.
Bro has a wumpus plush
It would be so cool if you made it powered by the pistons, and powered a car with this.
he could just use pistons for stability and also as no colision part to keep the middle fixed
Disk flinger in instrument of destruction
I see new things in the background 😮
Scarpman try mechanical principles by art of rendering you should try one of them
Day 310 of asking for more workshop hunters, and day 311 of asking for more brick rigs
For all of you that wants any of these you can help too
I think the piston is the one that should be powering the rotation if it were some kind of an engine?
tips for the mustache
Cool the power would come from the pistons
He should try to make it powered by the pistons by putting jets on the Pistons
I feel like the pink parts should be connected
