Happy new year everyone!
thanks
Have a great new year!
I have made a 3d printed running engine but it only ran for a minute then it melted and I made a new one
happy newyear
Happy new year 🎆🎇
I really love the fact that this project uses some of the most high-tech production methods and some of the most low-tech engineering (like some chicken wire etc.) to produce something that is already existing for over a hundred years. Not bashing on it though because I genuinely love it and have great respect for your commitment to it
@@enriqueamaya3883shut up
It's actually good that you didn't resize the whole with a dremel. The chances of it remaining round are very low and those threads you made are possibly the best you could have made because of the amount of material remaining. Do a quick test of a tight hole and a more sloppy hole and then add threads. The sloppy one will feel sleepy with a bolt in it and the tight one will feel tighter. Now measure the amount of strength you need to strip the threads and I bet you 1 kiss that the sloppy hole will strip out much quicker and than the tight one.
Yes I did write Whole instead of hole, no I won't fix it and yes I will blame autocorrect.
grinding it for 30 seconds would be best, just to remove a little bit of material to easen up the manual resizing
@@giovannicesaramorim9adigan961 using a broacher or a reamer would be the optimal thing to do.
The reamer tool is the best choice! Someone already mentioned it. It's specifically designed for slightly widening holes to specific sizes. While they should be done on a mill for the best results, I've used them on drills just fine. They have a long stalk, which means that they naturally flex slightly to center themselves in the pre-existing hole.
Given the available tools, using the tap gently as a drill probably gave the best results possible. It would have been very easy to knacker the whole with a dremmel.
Lol "sloppy hole"
For making prints watertight, I print with ABS and then vapor smooth them by heating a tub of acetone in an enclosure with the prints. Makes a really smooth surface and doesn't cost much at all.
I got even PLA prints completely watertight by increasing print temperature and reducing print speed and part cooling. With a bit of experimenting it held 2 bar of pressure no problem.
You can also print PLA with atleast 5-6 walls and a 50% infill @@TheLordNemesis
@@TheLordNemesisYou can also set the width to like 140% and the walls end up super solid. 5bar should be pretty easy
I Don't know much about 3d printing but was gonna suggest that or coating the entire thing in an epoxy or something like jb weld to seal it.
That method can deform parts and ruin tolerances
I've always been interested with the properties of metal 3d printed parts so this is an awesome vid for me, awesome work dude.
Btw, for making solid (water-tight) 3d printed plastic pieces, there is a method but it's a bit time consuming. It's called salt remelting, it requires that you print the part at 100% infill, then submerge it fully in salt, ideally as fine as you can make it, then you put the whole thing into the oven at just beyond the plastic's plasticity point (depends on your specific plastic, I think PLA works at about 200C) for a while, then letting it cool.
The idea being that the salt prevents the part from warping or moving, and the slight remelt allows the plastic to bond together better between the layers, creating better water/air sealing, it also improves the shear strength perpendicular to the layer lines.
I wonder if an acetone vapor bath would have similar effects. That tends to melt the outer layers to give a smoothing effect, but it should be able to make things more water tight if left for a little longer.
@@DigitalJedi Yes, but only with ABS/ASA plastic
@henkvanvoorst8446 true. I forgot what he was working with and this came to mind as an easy way to get some sealing.
@@DigitalJediWhat plastic is he using?
@@nerd_nato564 I assumed ABS or PLA.
This is exactly why I am glad I was a child in the 80's. We tried making these things without 3D printing as there was none. Now, I don't really mean we would try and make our own engines, but we certainly made cannons that used gun powder, crossbows that could almost kill, and used gasoline for just about every thing we shouldn't. Watching this series has made me smile as I know that most of the time you are praying you don't get a face full of metal and plastic, lol. Awesome!
Designing and building an engine with such mix/match homemade and even with pro help with materials from PCB way is a very impressive feat. Can't wait till I see what you do next. Great job.
Great job shilling!
@@scottanderson6309 Who is shilling? I only mentioned PCB way because those are the parts he was unable to make himself, even though he designed the parts they made.
He's probably going to need a proper fueling system and some compression rings, it seems to run very lean and probably gets a lot of blowby through the rubber ring.
Impressive is not the word I would use ... perplexing or confusing comes to mind ... makes funny content though.
i think that 1 cylinder boi wants an turbo
Really pleased that you managed to get it to run this well! Loved following this series of videos and your other projects. Looking forward to what comes next!
I was hoping you were going to revisit this but casting the parts using the plastic parts to create the molds. I want to build a 1/4 scale V8 this way. There is an LS V8 that is already done for 3D printing
The “let me show you on my computer!” Part got you a new subscriber buddy, hilarious 😂
with how well the engine is running I suggest somehow making some kind of crankcase vent so it can breathe rather that will be in the oil cap or somewhere else also maybe valvetrain lubrication would be cool to keep it up!
The saga continues, nice to see it man! I hope you keep it up!
Its pretty cool seeing how the engine evolves every video
Excited to see some more engines on the channel
When you're hand-lapping valves, i highly recommend using a bright light to see whether you've achieved full seal.
I work in an old-school machine shop, and i've been taught to check valves with a light first, before we even pulled a vacuum through
Man, this is beautiful. I’ve been looking forward to this engine running for a good amount of time.
I think I’ve said it before, but I think this video demonstrates the need again, I’d love to see you build a lathe using printing for as much as possible.
Maybe lathe for wood and other soft material. For metals, I'd say it's a no no. If you're familiar with Uri Tuchman, he once tried making a mini lathe for brass, IIRC, and it didn't go very well unfortunately... :(
@@rizalardiansyah4486 Yeah, Uri's the man. I hated to see how his ultimately failed. I don't think a 100% printed lathe would work/be useful, but I think a lathe using a lot of printed parts, like pulleys and such, is perfectly doable. I think for aluminum and softer, a CNC lathe would be pretty easy to cook up from off the shelf (Amazon) components.
What a good video to start off the new year!
That tapping sequence was sooooo hectic! I liked those tapping and welding shots you did throughout the building sequence
'Let me show you on my computer' was such a good gag too!
I love the little dipstick you added to the oil fill port's screw, and the screw itself is a good addition I think ;D
I am so glad to see you have taken what you've learned from the past and turned it into such a success, its really cool to see the engine you built run for so long
Legitimately impressed that you didn't break the tap
Happy new year🎉
I think the issue you had with the first pump was actually something to do with priming rather than flow rate but the second pump was definitely the right choice.
Each episode he slowly strays further away from plastic
It's remarkable how you've straddled the line of doing things correctly and sketchy
Happy new year 🎉 I love seeing this 3D printed engine since I've always wanted to design and actually build my own. This video series will have to do for now, but whenever I can get my hands on the tools I will try to design a legitimate metal engine, or maybe even try a metal infused 3d printed engine.
The engine is probably dying because when combustion happens, it's warming the plastic of the cylinder walls faster than the metal piston. They expand at different rates and you lose compression. On a conventional engine you can tell when this happens because the engine begins to race (choke has caused a rich condition, warming cylinder walls increases fuel vaporization). It's also why you can't properly measure compression on a cold engine.
You can probably start it without the propane if you just use a choke, as well.
Awesome project and I'm loving watching along, good luck on whatever you do next!
How much heating do you think they're seeing after 10 second runs really.
@@Idiomatickit's a small explosion, all the energy is converted.
@@noahprussia7622 if all the energy is converted into heat that would be concerning for sure.
It's amazing what you could do with 3d printing.
Also I love that your videos are more down to earth and isn't everything perfect or your have everything perfectly calculated beforehand
Such a cool series! Looking forward to having the engine run fully!
Great job! Very impressive.
You are legitimately the most underrated CZcamsr on this platform
I think u cant be a CZcamsr on any other platform
Alot of weed eater engines use the same method of making a crankshaft as you did! They compensate for the wait by welding three plates on each of the crank journal to add extra weight. It's really cool because out of all the weed eater crankshafts I've seen now I kind of get how they're made
The way you get things to works with a series of hacks, combined with your complete disregard for safety is very relatable to me as a brazilian, great job getting the engine to work 👍.
Yeah, it honestly literally sounds like its getting too little fuel. I have a briggs and stratron engine that I have worked on, and it keeps on stallling out like your engine does. And it turned out to just be a throttle problem by not letting in enough fuel.
Ps, awsome video!!!!😃
Also, I know this might not be a very good idea but what if you add a fuel pump on the fuel line to help with it's low amount of fuel withdraw...
Silly question but have you thought of 3d printing a mould and sand casting a block out of aluminium or other metal?
2strokestuffing has done this
Yeah, it's way easier and even cheaper to buy a small furnace, crucibles and crucible tongs.
I'm happy I keep tuning into this, seeing that engine kick on was so satisfying.
Holy cow, you actually did it!! That's just awesome, man. I love this series so much!
Dude, you don't know how excited I am to see this thing run. Been checking the channel every other day for the video.
Also, the rubber compression ring will probably never fail you. Seen a video by garage54 where they used a rubber compression ring on a real lada engine and it was impossible to melt.
That same video gave me reassurance about my choice to use the O ring aha
Excellent work! Time for more cylinders!
Finally! I was waiting for the 3d printed metal engine! Ive been watching this project since the original, and im not disappointed. Cant wait for the other ones 👀
Great job, and happy New Year!
The fact alone that it’s running even for a short time is impressive! Love this project :)
One thing I think I should’ve suggested a little while ago, would’ve been going with a flathead engine. If you went with a flathead engine, you could’ve just used a chunk of steel pipe for the cylinder sleeve and then welded a piece of flat bar with a whole drilled out for the cylinder sleeve, and two for the valves on top of it. Then 3-D printed head would work for probably a minute or two. Also, that would give you the ability to put an acrylic head on there and see it working with a clear head. I think that’s what I’m going to do with my engine, but as of right now I’m in Florida, so I can’t. Really love your channel and your videos! Keep up the great work!
This is one of my favourite 3D printing projects. It's really interesting seeing which components can survive being plastic and which ones need to be upgraded to metal.
your like the only person making these 3D printed thermic engines and actually making progress
He is the best one I have found, i am working on my own 3d printed engine, it is on my channel, but I tried a 2 stroke engine.
Keep up the good work,enjoying seeing your project👍🏻
I love this video! It's a combination of hilarious and totally intriguing. I love your curiosity and getting your own firsthand knowledge by testing all of these elements. This was really fun
Thank you!
Wow thats one of the best videos youve made yet, please make more like this and happy new year to you too!
i cant believe every thing you done is all what not to do,
but it was fun watching you try, and it almost worked,
Those metal parts came out nice
looking forward to an update video of this project working
Happy new year Camden! So cool to finally see it run!
Happy new year!
this is a great start to 2024 for me
i am impressed at your commitment and skills, keep up the good work
and happy new year
Happy new year and keep up the good work!
Brass pipe cylinder liner....atta boy! Worked! Proud of all you've learned! Look at you go!
Nice video to end the new year!
Dude you are so close to making that thing actually idle, ive been watching this since day one and im 100% confident youll get her running good one day. Keep at it youre doing an awesome job!
Love the madness and creativity in this thank you!
Severely underrated channel you have here. Also happy new year!!!!
The reason it kept stalling is because the o ring was getting warm from all the blow by, throw a set of piston rings on it and make the bottom end case stronger, design it like a motorcycle case where it's split in the middle and not half way, that will let you have a stronger bottom end and less oil leaks!
I’m working on my own 3d printed engine, so that might be useful for my engine! Thank you!
This is such a bespoke piece of equipment, and I love it.
It sounds really nice. What an accomplishment. You are my hero.
bro you have no idea how much better my day gets when you upload
I like the way you do your projects, try, fail, investigate and improve. That kind of thinking is what we need to progress and make the future 😄
watertight cooling jacket ideas:
- seal it by dunking it in paint or something
- print with 4 walls and very high temperature and >105% flow, and fairly large layer height to minimize the potential failure points, and print slow. And make the geometry simple. No overhangs, no fancy features, just a cylinder.
u have inspired me. I am currently designing a compressed engine with self actuating VVT. basically copying you but I need to start somewhere. awesome vid dude.
Been here since the first 3d printed engine glad to see this outcome I can’t wait to see the next video!!
Finally, thank goodness! You've been creating these 3D print engine videos for quite some time, and now it has successfully run.
There is so much you can do to make this even more amazing. Adding in a some timing featurs. Maybe an actual cooling system. Throttle cable. Fuel pump. This could become a full running working engine that you made at home and that would be an incredible feat of engineering. You got a follow from me for this one. Awesome work man. Can't wait to see what other cool things you do
Thanks a bunch!
I've really been enjoying watching your projects. Keep the inner mad scientist inside you alive and well. 🤘🏻
welding bearing races. resizing holes for threads with rotary tools
much good, very success !
My favorite CZcams series!!
You should try 3d printing a 2 stroke engine I think it would be interesting how you would design the crank case
HELL YEAH! Just saw you uploaded a new video, great way to start the new year!!
that engine shakes soo much more now flinging that metal piston around. great vid dude! love it
Excellent work man. You are so smart in mechanical engineering. Keep at it.
Thanks for uploading on new years!
A good start to the new year.
I recently replaced my vespa's cylinder and honestly, i have so much respect for what youre doing
FINALLY! Another video on this.
Bro is slowly getting closer to running a gocart off of his 3D printed engine and I am all for it
the 2nd thing thrown at the laptop earned you a sub
Starting the year with a banger. I see where you're going
wow, you posted this exactly at 00:00. HAPPY NEW YEAR!
Happy new year bro!
Nice! I haven't watched the entire vid but I'm already enjoying it!
Absolutly amazing, cant wait to see one powering something like a bicycle or gokart
OMG why haven't I bumped into your channel earlier???
I used to work on 2 strokes engines in the late 80's, back then we were tweaking what we had to work with, and the process was fascinating.
What you are making here is the most bananas thing I've seen and I'm loving it!
As I watch you try new things I'm "this can't work", but when you figure it out it's like "I knew he could come up with a solution" :D
Thank you for sharing this 🙏🏼
This is genius and fun to watch. I wish I had paid more attention in auto shop when we rebuilt lawn mower engines.
The best way to start out the new year fr
YES NEW VIDEO happy new year camden bowen
Before running a tap through a tite hole, use a reamer. It's in general a good idea to have a reamer for the size the tap requires anyways, so do that for future stuff. Drilling a hole for a tap isn't enough.
Dude this is awesome! Keep up the great work!
I am proud of you Camden :)
Happy new years btw
You did a great job man! From plastic and JB weld to a fully functional engine. 🤔
That's something to be proud of
i need more already fugg this is sooo good
Incredible work!
Just a tip from a fabricator, when tapping holes just use a drill bit, plenty of drill bit to tap charts online.
I have been waiting for this video FOREVER. I would check my phone countless times a day!!!! TYSM!!!!!!!
Love you videos! Keep up the projects
happy new years evereone super cool video
Congrats on making it run for so long! Nothing short of an impressive feet!
holy shit, dude... i was already laughing pretty good when you 'sent off the package', but i wheezed and crylaughed so hard when you showed us what you were talking about with the piston on your computer. so amazing. thank you lol
