Lots of comments saying to 3d print in metal, or cast the parts, or you could use a 5-axis machining centre but I think the point is to see what can be done using what is at hand, a 3d filament printer, hand drill and a few tools. Thanks for the series Camden

[@sparky-jo7dk]

I was really happy to see this video! I'm glad you haven't given up on it. It's cool to see the progress even if it isn't yet successful. I like where you are going with this. I believe reducing as much friction and mass in the gear train for the timing/valves could help, It may be that the piston can't overcome that load. Thanks for the video!

[@CamdenBowen]

That's a good suggestion, The gears may create a lot of friction but from what I can tell most of its resistive forces are due to the compression stroke. Thank you!

[@itsb680]

Loving this series. Convinced me to try my own 3d printed gas engine. Came back to see how you where handling the ignition timing, and spotted this new upload. Keep up the great work!

[@CamdenBowen]

Thank you so much!!

[@cohenhill6376]

This is getting so close to working! I think the only thing preventing it from working is the valve size. Maybe try increasing the bore of the engine so you have more room for the valves.

[@CamdenBowen]

I was thinking of stepping the bore up, I just need to find a cylinder sleeve to use

[@cohenhill6376]

@@CamdenBowen Maybe try and go to Lowes or somewhere and find a pipe

[@3v068]

You and Tom Stanton are absolutely mezmerizing to watch. Keep it up man!

[@slatetechnologies1724]

I think the reason why you keep running into issues with your engine is because you 3D print it out of FDM. Try SLA, which should help you get a much better engine due to its heat tolerance. I own an SLA 3D Printer and once tried to burn some sample prints from my SLA 3D Printer. It didn’t really melt but anyways... Hope that helps! Also I’m thinking about taking on this challenge myself, although my 3D printer is broken at the moment. EDIT: Oh yeah, another plus of SLA 3D Printers: they are great for air engines that NEED A LOT OF SEAL. Seeing that this engine probably runs into a LOT of sealing problems I think you should try using an SLA 3D Printer.

[@CamdenBowen]

I do think that I need to try an SLA lol, I'm thinking of getting one myself for projects like these.

[@powerbanger69]

[@a41capt]

The way your engine backfired, I would look to the ignition timing. If you’ve got good compression, valve timing is good, but I believe ignition timing could be advanced a bit. All of my model engines took a considerable amount of fiddling to get them running since scaling down makes for difficult running. Also, butane, as well as all LPG products, tend to require s richer mixture than the longer chain hydrocarbons. This means a smaller venturi as opposed to one for naphtha (white gas, aka camping fuel). Nice work, interesting trouble shooting methodology!

[@CamdenBowen]

Thank you! The tolerance between the gears may have disrupted the expected ignition timing as well

[@yeets723]

This series has been sick asf to watch, I'm excited for episode 5

[@quesadilla7760]

Have you considered using a “bubbler” carburetor by drawing air through a closed bottle or something to mix the air and fuel vapor?

[@CamdenBowen]

I haven't but it seems like a good idea, I just don't know if the engine has enough displacement to draw in enough air and fuel

[@Cole_Tilton]

you should try a 2 stroke i believe it has less chaos but Im no expert keep up the good work

[@CamdenBowen]

The first version I made was actually a two stroke, however it had a poor design and never worked. I wonder if I could try one now?

[@Grillkol]

The main problem is probably the air/fuel ratio. For the ignition you could try some 18650 batteries instead. I find them more reliable

[@CamdenBowen]

Yea, these 9v are pretty unreliable after a while, but for short periods work fine

[@birthdaysnake23]

You can eliminate almost all shaft play while saving space by using two angular bearings in a tandem configuration

[@mr_bear6362]

I like to use Alcohol soaked nylon as temporary gaskets, works pretty well until I finish a prototype and want to actually buy proper gaskets and seals, even non-soaked nylon works decently since it's a softer plastic

[@CamdenBowen]

Do you use it for metal on metal?

[@mr_bear6362]

@@CamdenBowen Not usually, though I did use it as part of an attempt at making a compressor, rubber and silicon have much better seals, but nylon works as a temporary testing gasket. I think the only time I used a nylon gasket metal on metal was when I made an air powered dremel that blew up in two seconds because I didn't make it strong enough for anything over 40 PSI. It was basically an air engine with an aluminum pipe as the cylinder wall

[@cenreaper9127]

Put a metal pipe on the piston and cylinder in the carburetor to have a good seal. (Or just put some kind of a plastic membrane as a seal).

[@CamdenBowen]

I could but I don't have any that size, it isn't subject to much pressure so it doesn't really need a perfect seal

[@cenreaper9127]

@@CamdenBowen Maybe that low amount of pressure you ignore is making your engine still dead.

[@roarore8810]

Making a engine with a really low bore-stroke ratio may be a good idea as it will want to run at a lower rpm and will give the butane more time to move through the intake and into the cylinder. And I know you already increased the weight of the flywheel, but increasing it even more may be a good idea. Single cylinder engines are not the best at idling smoothly (usually need to idle at 1500-2000+ rpm to be smooth) and with a weak power stroke I think it'd be hard to get it to run without an almost excessively heavy flywheel. I really need to get my hands on a 3D printer, I've been thinking of experimenting with 3D printed ICE's for a little bit, which is the main reason I ever discovered your channel. You've come a good way from the first video, I'm sure you can make it happen.

[@cemmy410]

Love how the project is coming along! Next time can you duck the volume when the drill is running? It was so loud I had to keep turning the volume down, then when you started talking again I couldn't hear you and had to turn it back up which was a pain and made the video difficult to follow

The results from your material test make sense. Nylon is the worst for absorbing moisture.

[@zachmartinez2295]

It's possible there simply isn't enough fuel in the cylinder to make enough power to kick it over

[@frizzletits8511]

The fly wheel needs gear teeth on the sides so you can build what amounts to a bendx you can spin with your drill

[@Foppa905]

Plz part 5

[@AxelDayton]

Is there any chance your intake valve is too small? The fact that you can hear popping says that the engine has all 3 components of combustion. I think the only thing you may still be missing is just more air and fuel. I know with your cylinder head design it may be difficult to increase the intake valve area, but if you could find some work-around, it may fire right up

[@CamdenBowen]

I was thinking of stepping the bore size up and fitting larger valves, it may help reduce resistance as it will breathe easier

[@christanvandijk5106]

Realy nice, the videos on this project are always interesting. What are you gonna do with it when it runs?

It isn't going to spin much faster but also, it won't spin for long enough to start

[@blahhaha253]

a tip i have is use pure alcohol or at least 98%. if you use 98% then it has that whoof like gasoline. 91 is pretty weak when it comes to flammability

[@ARockyRock]

i thought it was a lego piece in the thumbnail

[@tandr3w]

I think the problem is timing/the drill rpm is not fast enough. I had a hit and miss engine kit and tried using a drill. I had to attach a wheel to the drill to start my engine.

[@LukieHZX]

Nice episode again! I have something you could build im the future: A starter motor, then, you would not need a drill. I don't know how long it would take, but if you have a good idea, that is build fast, do it, would be really nice!

[@CamdenBowen]

Thanks! The reason I chose the drill is it has enough torque and speed to make an appropriate starter, a starter motor would have to be pretty big to make it work right and it could be a bit of a hassle

[@LukieHZX]

@@CamdenBowen Yeah, sure, I understand, why you used the drill, but I thought, maybe you can find something, that would work as a starter motor.

[@KmcOffroad]

Try a rotary style valve instead of the standard push type. You may be loosing more compression than you think.

[@CamdenBowen]

I thought about it, I would just need to figure out a design for a seal around the stationary parts of the manifold that seal against the disk

[@KmcOffroad]

@@CamdenBowen use a roller pin style valve. Think a hallow tube with ports on the side. Then you can drive it like a normal cam 2:1 drive gear. Plus orings can seal it easy.

[@KmcOffroad]

@@CamdenBowen you could try a reed valve for the intake. Then you only have to worry about the exhaust side.
