The Modpack has a "block" that has a sphere collision, would've been perfect for the ends. It's a full block diameter so it'd put everything where it needs to be. MIGHT have to make the whole slider out of them but best solution I can think of.

Something tells me the sticking was probably made worse by the engine being on the end of the arm. The weight being so far from center caused more stress on the sliders and forced them out of the rails

Hoping you have good day, Scrap Mechanist! I've got 4 days before a lung transplant and the videos you and Kosmo post keep my spirits up! Surgery went well! Thank you all for your kind words!

I'm pretty sure part of the problem with creating a trammel where the force is not applied to the handle is that the bearings on the 2 arms are rotating at different speeds

2:49 this sort of device was used to draw graphs back in the day before computers. If you wanna find out who invented it you might wanna look into that. Decartes might have used then.

I actually made a piston engine using that setup, and I call them Tremmel Engines. They have SOOO much torque!

AVE Mizar in TM. "the AVE Mizar is a flying car that actually took to the skies. But rather than designing it from the ground-up, the creators of the Mizar just made a mashup of a Ford Pinto and a Cessna Skymaster. Unfortunately, instead of being the next step on the road to the future, the Mizar ended up filling the next page in an air crash investigator's notebook. The concept was for a modified Ford Pinto to drive to the airport, bolt on a set of wings and an engine, and take off. By using the car's engine as well as the propeller, it was capable of remarkably short take-off runs. Plus, by using all four wheels for braking, it needed less than 550 feet of runway to stop after landing, which is pretty remarkable. Unfortunately, despite claims to the contrary, the Skymaster-from which the wings and engine were taken-was never rated to carry the weight of a Pinto, let alone passengers and fuel. Add to that a poor structural design, bad welds (according to the National Transportation Safety Board), and an inexperienced pilot, and you get a tragic accident that kills the vehicle's creator-and the project along with him." -From your loyal subscriber, AspieSpark

I love this series and I enjoy your content. Keep up the good work. You are really talented both in music and your videos. Thank you.

You could do a series where you find the best creations for a specific category in MMM and compete for first place. There could be a selection of 4/3 creations to choose from and you randomly decide the order people get to choose. This could apply to pretty much all the games you play on the channel!

This has to be my favorite video of yours. The KZfaq channel MakersMuse, where the guy has a book of mechanical inventions, and remakes them 3d printed; is what you should do in Scrap Mechanics!

I think problem was bearings, as they are powered but expected to turn on different speeds in relation of position(since its elipse, not circle). Red block movement adds or remove speed of bearing, but since bearing is moving at constant speed, it gets stuck eventually.

I'm so glad you started lengthening the bottom of the sliders, when it got stuck that was my first thought! I'd love to see you try making this as big as you can ♥️

I feel like a possible fix would be to have a track on top for one and on the bottom for the other, so they never have to leave their track to pass each other. A little less visually satisfying though.

The last one was a perfect circle because the spudgun was in the middle between the bearings right?

Hey ScrapMan! MM idea: use this machine for a race, you have to roll a random number between 1-10 that determines how far you put the spud gun from the end, then the shape you get is your wheels

The Trammell can be upgraded to have more tracks. Like 3 to 5 total moving pieces instead of just the 2 that go back and forth. And they make different shapes. I think it would be hard but cool

You are getting so good at these mechanisms scrapman! Keep up the great videos!!

Try to make a clock with all the mechanisms you made?

Also, these are definitely the best (and only) ellipses I've seen in Scrap Mechanic.

You should make one of those switches that turns itself off when u turn it on

this channel is a gaming channel and a history lesson channel, love it! also scrapman, just make the thingis inside there out of the low friction block too

Imagine if you made a machine that combines all the past mechanisms you discoverd.. could be super interesting

Really really interesting video, cool to see the time and effort you put into researching and sharing what you found ! And your machine works very well considering the physics of scrap mechanic It might be possible to make an even faster version of it by putting the moving yellow beam in between the two rails. With that setup you can make the rails without cutting them in the middle because they don't cross each other. With that you don't run into this problem where too many blocs are in contact. But what you've done works perfectly, so there's no real need for improvement

I love the "mysterious" feeling, it makes my day. Thank you.

I like how you are checking out these mechanical devices. What machines could be more useful in Survival mode? Sure, we build trucks, and miners, perhaps even a flying machine for getting around quickly. But I feel that's where SM:Survival's building needs end.

This machine is pretty important, because from mathematical point of view, an elipse doesn't really exist. Elipse shape is a combination of ever changing equations. So this machine gives a precise geometric way to draw/model this shape at various configurations.

I made this in scrapmechanic right after I watch this. Thank you for the inspiration to build something in scrapmechanic. 😊

Maybe it's called the Trammel of Archimedes because it relates to his works and studies?

You can use it for creating circles in 90 degree build grid, that's nice.

My science teacher had an entirely metal/steel one of those. It was pretty cool, very small, but still very fun to use.

I love this guy, you always learn something new from his videos X3

"A good place to start would be to put low friction blocks since we're gonna need some friction on this thing" - scrapman 2022 @ 3:55

Props for uploading so often👍

This was pretty cool. I made one once, that had three tracks to work on. Might be difficult in Scrap Mechanic, but in another one of your programs, it would be cool to see.

0:45 scrapman: ive been subscribed to this channel for a while now. Me: than whats that big red subscribe button in the botom right

If you put the smaller ellipse inside the bigger one, there should always be the same distance from the inner elipse-edge to the out ellipse edge. Also, if you put a "handle" on the other side of the yellow bar, you can draw an ellipse exactly 90° turned from the previous ellipse. Because of that, it makes sense that there is a point where it draws a circle. The closer you put the "pen" towards the connecting pipes but still outside, the more and more the ellipse becomes a straight line. If you put the pen exactly at the point it is connected to a slider, it will just draw a line back and fourth. Now if you move the point of the pen towards the other connection-pipen of the other slide, the "outer points" of the drawing will shift to become the line 90° rotated from the first line of the first slider, and furthermore create the 90° rotated ellipse. So if you put the pen exactly between both connection-points of the slider, you will logically have a circle. Which is mathematically pretty awesome.

"I've been subscribe to this retired scientist for years now" Me looking at the red button XD Love you Scrapman

I was thinking. If you cut the cardboard, then moved the spudgun in by a block, replaced the cardboard and repeated the process, you could weld all the parts you made at the midpoint to create a 3D object. It would kinda be like having a 3D printer but in Scrap mechanic. Albeit one that could only print 'eggs', but still pretty cool.

Try to make the Amphibocycle. I think the name explains it all.

This could also be represented by two circles and a line where there is a circle with half the diameter of the first one and it is placed inside the first one

I realized, the position of one of the beams is sin(t) and the other is cos(t) He made an analog to trig functions

I am currently working on making one of these in real life and you are going through the exact struggles I was going through

Infinitely on edge and infinitely relieved

could use this for another type of walker motion. Also, the end of the top portion of the slider might be able to be centered using a large pipe piece pointed upward instead of making them longer with the corners/duct

Archimedes was an absolute mad man

Scrap Man:"I've been subscribed for a while" Scrap Man's Computer: "Subscribe"

congratulations, you now have a means of making almost perfect round objects for your building needs just create your ellipse then replace the material when you're done, i suspect to see more rounded creations in the future ( or not, you're choice really )

Yes subscribed, I wonder why the box on this science guy's channel is red instead of grey?

Scrap Man: Ive been subscribed to this channel for a while. Me: What is that red button there? XD

I once was messing around in scrap mechanic with some '30's russian opposed piston steam locomotive concepts, with some succes, would be fun to see you trying to build some. If you google 'unusual russian locomotive technology', you should find it. I had a wall preview build of one of the concepts that I altered to be vanilla and I've uploaded it on the SM steam workshop under the name 'opposed piston train concept'

0:48 I like how he says hes been subscribed for a while and the sub button is red. Great content though!

I wish I was a retired science teacher so i could have scrap man subscribed to me

you should build the p.1000 landkreuzer "ratte" tank. It was a 1000 ton superheavy tank proposed for the axis forces during ww2. I think it would be very interesting to see you make it.

0:47 Scrapman, there is no need to lie... we can see that you are BSing us right now 😂😂

I'm wondering if you want to disconnect the bearing to the one slider as it moves at a different rate then the center as it travels up and down the slide.

scrapman: ive been subscribed to him for a while *scrolls down to his profile while clearly not being subscribed*

Scrapman:ive been subscibed to this channel for a while now Me: ... scrapman you forgot to subscribe

Well done! Entertaining and Educational!

You should make a walker that walks like a camel, camels have a very strange walk cycle for a quadruped.

GOOD OLD BRUCE!!! He's hilarious isn't he

I guess it's called Trammel of Archimedes because it uses the lever principle to differ between the two widths of an ellipse. And Archimedes is kinda famous for his work on the lever principle.

Make sure that KZfaq didn't unsubscribe you bc in the clip that you said you had been subscribed for a while, you were not subscribed. I really like the series though.

Are you able to make a key/lock mechanism? Please i have asked you many times. I would really like to see it on a working door too.

SM: I've been subscribed to this guy for a while- Subscribe button: are you sure about that

Now replace the spudgun with a platform on a bearing rotating the opposite direction that has a few seats on bearings rotation the same direction as the trammel and you have your very own carnival ride.

I really wish there was like a paint gun. It would be great for stuff like this, and a bunch of other things.

You accidentally made a "Rope jumping game @ 11:12 " . Make a skyscraper or make it a hover drone sorta thing and use it with mulitplayer monday. Do a "Free for all fight". Whoever stays on the top the longest, wins it al!

I actually built one of these in scrap mechanic before. You need to make the moving rods longer.

Scrap man: "we are dealing with relative big Block dimensions in this game." Meanwhile Minecraft: ...

Oooo, can you try the Walschaerts valve gear mechanism. It was an important mechanism in steam locomotives and allowed proportional control for a reciprocating steam engine

scrapman i have an idea you should make the 1950s rhino car/tank with ball wheels

YEAH i love bruce yeanys videos they're always so fun!!! I've been subscribed for a while 😊

I’m not certain that this would work, but I was just thinking about a possible solution to the collision issue. If you made the connection between the two arms on the inside of the contraption, then made one channel on the top and one channel on the bottom, they wouldn’t ever have that possibility for collision with the other channel. Of course, that would be fundamentally different than the real life equivalent

Automated Circle Maker, never thought I'd see the day

Hey Scrapman🖐️. I have a suggestion to build: since you made real life mechanisms and failures you could try an unballanced wheel perpetual motion machine.

next: you should watch a documentary and try to follow along in SM, TM or MA

You have got to be kidding me literally earlier today I saw this in a Vsauce short I thought it would be nice if scrap man made this

I was waiting for this

This may be a bit too complicated. But you could check out Fourier transformations or Fourier series. It's able to draw whatever you want. Should be possible by using controllers at different speeds 😁

Hey ScrapMan! Try making a self balancing unicycle that you can drive around with. I don't know if you should make it in Trailmakers or Scrap Mechanic, just build it in what you think would be better.

I've been subscribed to this channel for a while *Big red button just chilling*

your vids are the best I love what you do

0:47 "ive actually been subscribed to this channel for a while" The red subscribe button: "am i a joke to you?”

Scrapman please do the "rhino"! It was designed to replace tanks, made in 1954 would be awesome to see!

Maybe the next multiplayer monday could be this jump rope with this gradually encreasing in speed.

You Know this machine would make a great motor for a multi-legged walker

Idea....make a car using this as wheels obviously needing wedge pieces or something to make the round shape

Scrapman you should make the failed vehicle called rotodyne for your next video and loving the series keep making funny videos like these. Edit:- It just doesn't make any sense and you will have to build it in trailmakers.

Hey, archemedes! My favorite engineer

0:44 ive been SUBSCRIBED to this channel for a while now Me: 🤔

Scrap man: "ive been subsribed to his channel for quite a while" Also scrap man: not subscribed

I can tell why it was getting stuck. Fritction does not work well with weight in scrap mechanics, increasing speed is decreasing friction instead of increasing it... Friction in this game works as a "slow down" instead of "impact/force dampener" Try using lightiest possible material in the upper mechanism and throw engine under the construction.

i suggested that about 1 hour ago lol before this was posted but i think after it was recorded

I've been binge watching the channel all week, you every going back to survival?

0:50 “I’ve been subscribed” the subscribe button being red

Scrapman! Devblog 23 is here! THE NEW SAWBOT ALLOWS FOR CUSTOM WEDGES!! #WedgeGang

wow this is the earliest ive been on its like 4am here in idaho

Now you can make elliptical gears in Scrap Mechanic!!

Oooh, here's an idea: see if you can build a turbo encabulator.

Some default parts could help of you put them on the leading edge of the sliders, as well as low collision blocks
