  • Now that the engine is running really good, there is a couple of things I can do to improve it and make it run longer. The first thing is, I need to make aluminum valve spring retainers, And then I need an aluminum piston and bearing bronze connecting rod.
    Please make sure to subscribe and leave a like on this video, I want to buy a milling machine so that I can make even more homemade parts!!!

    Make your life easier and get a corded drill to turn the engine over, also if the carb is leaking fuel you probably need to adjust the float so it cuts off fuel earlier.

      I like pull starting it, I could use a drill, but if the engine backfires I will loose my wrist.🤣 I actually didn’t notice it was dripping fuel, but I had the same issue with the previous carburetor that was the same one.

    I really love this project! A real post-apocalyptic job. A couple of thoughts:
    Using a glass container for a fuel tank is a hilarious design choice, especially with all of the vibration. Consider mounting it to your workbench using a longer fuel line so the vibrations don't bounce it around as much. Don't let your homeowners insurance company find out!
    Consider a dial gauge and a spark plug hole adapter to find TDC. That's how we used to set timing on 2-strokes back in the olden days of the 1970s.

    Maybe some kind of exhaust could make the exhaust valve to run cooler so it doesn't melt the retainer that quickly? Either way you would need to go full metal in order for it to function a considerable ammount of time. Maybe the connecting rod could stay plastic.

    • @ProjectLMZ
      @ProjectLMZ  3 หลายเดือนก่อน

      I have a feeling after I upgrade the piston to aluminum, the connecting rod is no longer going to be strong enough due to the increased load. The aluminum piston will be about twice as heavy, and I don’t know if I would trust this connecting rod with that. I could try to make an F1 style piston and stick with a plastic connecting rod, that would be pretty cool!

    You could definitely make a metal piston and connecting rod with the tools you have. A piston is just a cylinder with a hole in the side and a slit out of the bottom. You already have a lathe and you could figure out the hole and slit pretty easily I sure. The connecting rod is just a plate with 2 holes in it. I’m not sure how your bearings are set up but I’m sure you could get them to press fit into the new metal parts. I do like the plastic piston with a steel shield though.

    • @ProjectLMZ
      @ProjectLMZ  3 หลายเดือนก่อน

      The issue is that my counterweights are a set weight, So I can’t make the piston and connecting rod too heavy, and the connecting rod has to be like a normal engine, I’m going to have to make bearing bronze bushings for the Con rod where it clamps onto the crankshaft. The main issue I’m worried about with making a piston Is that since I’m using a steel pipe for the cylinder, when steel and aluminum come in contact under high friction and high heat environments, they get galvanic corrosion, and then they gall and friction weld themselves together. I could anodize the piston so that doesn’t happen but that would have to be in the future as my budget is basically zero right now.

      @@ProjectLMZ that makes sense. I’d have to see the internals again to be able to suggest anything. If this is just meant to be a fun project then I wouldn’t be too worried about galvanic corrosion but if it’s something you want to actually do work then I’d worry about it. The heat expansion of the steel vs the aluminum could be something to keep in mind too. I don’t remember how you have the counterweights set up currently but with how stiff the shaft you used on the crank is you might be able to counterweight the internals from the flywheel. If you weren’t aware some engines already do this. Keep pushing I’ll be waiting for more updates. I love this kind of content.

    i think you should go for the 2 stroke, the piston will cool better and receibe lubrication, also simpler, and make the piston smaller diameter without changing the cc, that will decrease the force it makes in the cranck. Im working in a similar project and what im going to try is printing the head and cylinder as the same piece with the porting premade, then put inside the copper sleve, and see if it works. Also becouse it is in one piece you can make passages for water cooling. Really like your series and this video too, but now is not 3d printed. Much love

I had a lot of issues trying to get the ports right, with my Dremel I just couldn’t cut them right, I ended up messing up three or four times, eventually I just said, screw it and tried using it.

    the timing needs to ignite fuel a bit earlier
    like barley earlier (I haven't watch the entire video yet)
    edit: I see you did fix it
    if it ever dies when you give it throttle and it responds
    but when you let off it dies
    it means your idle is too low,

    three taps... taper, intermediate, plug... really makes a big difference on tapping... also tends to pull itself straight...
    or ... learn to thread on the lathe. its scary. its satisfying. its what theyre intended for. then you know its concentric....
    you wont get that diameter, those lathes dont have the torque at the speeds it runs... too fast for carbide even...
    try a grinder... cover everything... spin the work by hand...
    lol, the evolution from printed to fabricated metal... the exhaust valves guaranteed to cause issues. they do tend to glow red hot on a real engine under load... and the only way they can cool is the valve guides, and the seats.
    could change tack... try a lenoir cycle or "non compression" engine... far less heat and strain on things... and its something... different. everyones stuck in a rut, it seems.
    pistons are easy to make but the most important part is the ring grooves, and the rings. the bottom of the ring and the top face of the groove have to be perfect... as thats where the main sealing occurs. the gas forces them down, and simultaneously gets behind them and forces them out.
    the hardest part is getting the pin hole bored straight and square. in all regards a lathe is better...

    • @ProjectLMZ
      @ProjectLMZ  3 หลายเดือนก่อน

      I like your idea for making a piston, I’m more worried about machining the inside, but if I get a good casting i shouldn’t have to worry, and for the pin, I would just measure from the bottom of the cylinder, then square in up in my drill press and then drill it.

    you can get terrible cross tables for mini lathes and use your mini lathe as a milling machine
    I will bet the tapers are not exactly the same an that's why it spun, properly made tapers on't nee a lot of force to hold really well together. Tightening the nut more will 100% fix it an it won't be a problem. I suggest putting a mark of some sort on the flywheel and crank an then marking the TDC on the flywheel so that you can take it on an off an you can align it easier purely for convenience, as you don't have a pin or a key to hold in position.
    you could also print a starter for your drill that will disengage itself automatically when the engine starts
    I personally would also make some sort of a simple exhaust from a pipe and a silicone hose to not fill up the shop with smoke, it's not healthy
    I bet you can get it to run properly and sort of reliably quite soon... just don't forget cooling or you might need a few spare cylinders

    • @ProjectLMZ
      @ProjectLMZ  2 หลายเดือนก่อน +2

      Thank you for all of the info! I did tighten the flywheel up some more, about 60 ft/lbs, and I have hade no issues, it will be in the next video, but I got the engine to run for 48 seconds in one go! Then my camshaft melted, from the friction with the exhaust valve roller. I am almost done, making brass rollers, and I have already made an aluminum camshaft. I don’t think a 3-D printed attachment for my drill would hold up, this engine has an insane amount of compression, I don’t have a compression gauge, but I’m guessing it’s about 100 or more PSI. Even though I could water cool it, the issue is that my bolts and all thread rods bolt onto the cylinder, but now that I’m thinking about it, I could probably 3-D print clamps on and then I use RTV silicon around everything, actually now that I’m thinking about it that would probably work great.
      3-D printed or homemade metal if I can find some pipe that would work, if I were to use pipe, I would cut it down the center and then weld a flange on each of the sides, then it will bolt around the cylinder and then I can make some thinner. Metal covers for the top and bottom, then I can weld everything together and when I assemble it, I just put red RTV around everything, I actually think would work!

    it hurts me to see the oil from the crankshaft just being all spilled out, i would make a 3d printed nut designed like a mufler aka like passage ways to not restrict the air but make it harder for the fluid to go arround it,and also pls add some type of cooling just bcs of how much water cooling can do, for example if u put a lighter under a ballon it will explode right? if you fill it with water and then put a lighter under it, it wont explode bcs it cant melt the ballon quick enough bcs the water is exchanging tempature so quickly that makes the ballon survive the fire, also nice engine, now put it on a mini bike XD

      Could even bunch up some steel wool in the crankcase vent to make it more effective at stopping oil, or perhaps a one way valve and get a vacuum in the crankcase, although I'm not sure how useful that would be.

    • @ProjectLMZ
      @ProjectLMZ  3 หลายเดือนก่อน +1

      The oil spilling is fine for now, with a plastic con rod it’s not doing much, but I need a good size relief, because it builds a lot of crank case pressure. I am planning on adding water cooling in the future, but there’s not a good way to implement it with this design, because I have studs running from the top and bottom of the cylinder.

      @@ProjectLMZ sweet as, you're probably aware but just incase you're not,
      an exhaust manifold will be very good for your motor because a lot of unburnt fuel is going through the exhaust which will overtime destroy the exhaust valve and may be why the valve spring retainer melted because the valve got so hot.
      the manifold will stop oxygen from getting to the exhaust valve so that would mean there will be less fire around it meaning it will stay cooler

That could be why, but also the hole for the valve stem is slightly to big, so I also think flames and hot gasses are shooting up directly to the valve spring retainer.

      @aroundtheyardfun I does indeed cut aluminum 🙃 I've been working on this cnc for like 3 years or so on and off for no real reason other than i wanted to. It's in the GEN5 iteration. I haven't released the files yet, but you could test run it.
      It is really big though, it does have the ability to be upgraded. It's supposed to be open source once it's like at a decent stage.
      Working area:
      X 550
      Y 450
      165mm Z travel ( adjustable Z plate though so it's like 14 inches of Z work area, you just have to like do it at as 2 jobs it's kinda odd, but its huge work area 😄 )
      Price is like somthing funky for me becuase I didn't think sbout tracking it 😅 I didn't want to feel the pain of development, but I'd say it's like
      2.8k for the gantry X and Z
      500 for the table
      And like 500~ 1k in electronics.
      It only has a 500w spindle mount, so I'd have to wip us up a 1.5k watt spindle mount if you really wanted that.
      I'm also still working on stuff, it accurate to like .008 ~ .01 mm range in aluminum with some software competition.
      I do have full table schematics, wire diagrams, and all the STL files are ready.
      It's a lot to print though, and everything must be printed to spec or solid at this point, lol. 75%+ infill and 5~6 walls and PETG or PC only.
      It took me a week and a half to print the Gen 5 Y axis
      I haven't made a real in depth video or anything. It's just been a vlog thing for me. Check my videos. I haven't done a GEN5 test yet with the new Gen 5 Y axis yet.
      It's taken 2 months to get it together though, I changed to 15mm HTD belts on the Y and 36v big ass nema 24s with a new desgine for the drive train components.
      The entire machine is belt btw, and the weight of this bad boy. Is heavy as fuck 😅
