If you make a full sized or double sized card board cut out ( I use ceral box stock) pin the con rod to the piston with a soft metal envelope seal rivit. Put it together just like your diagram. Use an accurate dimension on your piston height. This way you can see where your intake, exhaust, and upper and lower transfer ports best location. Port timing etc.
Ha ! My first engine was a tiny two stroke. The porting is kind of fiddly and then there's the crank case , it has to seal air tight. I built it B4 youtube existed but if I can do it ... You can do it.
I like your (new?) video style! You might want to calculate the compression ratio and change the heads height/volume to be somewhere around 1:8~1:9. Else I see some parts getting hot rather soon.
+Ron S thanks! Out of curiosity, what did you think was new about it that did you like? Yeah I'm going to try calculating the compression ratio probably in the next video. When calculating the compression ratio do I use the entire stroke length or only the part of the stroke that the ports are closed for?
The buildup in this video feels more structured (to me), and you make good use of the whiteboard. I never calculated on two-strokes since only four-strokes are allowed for our supermileage car. A quick look on the web gives me that you have to measure from the top of the exhaust port. Good luck, looking forward to pt3!
The reason small 2 Strokes have a divider is so the piston rimg doesnt enter the port :) i have an imsane cylinder for a yamaha moped with 6 divider walls, since the transfer port fills half the bore :)
If the piston is too tight fit i think that it will seize due to the heat expansion. That's why there is a cap between piston and cylinder in a gas engine and the piston rings do the sealing.
+NuffMan it's possible. Although the cylinder and piston are both cast iron so they have the same thermal coefficient of expansion. Also small nitro engines don't have piston rings.
+Clayton Fixes Everything I've been thinking about it. I have a really nice dual cylinder, 2 inch bore, 1.5 inch stroke air compressor that I'm saving for just that. I think It would make approximately a 1hp steam engine. Maybe make a steam bike?? :D
+InternalCombustionGenie hehe I've been wondering the same thing! :D I think it'll sound pretty nice. Maybe a bit of a high pitch to it due to ports opening a little early. I'm sure it's gonna sound like a dream come true when it first starts
That's great and all, but I think thermal expansion will cause you trouble. Piston might seize in the cylinder. Also Al has much higher expansion rate than cast iron, so I dunno how that will work out. I like your videos, don't get me wrong, I just like to think of possible problems way before they arise. Keep up the great work! I would love to see that thing braap :)
+MrJohhhnnnyyy yeah, you might be right. The piston and the cylinder are both cast iron so there really shouldn't be much of an issue there. If there is I'd think just letting it cool down for a bit would get it working again. I don't think the aluminum connecting rod should be a problem. It'll just get more slop in it as out heats up. I think aluminum connecting rods are fairly common. I guess we'll find out!!
+MrJohhhnnnyyy oh, good point. I'm planning to JB Weld the aluminum head on. Worst thing that can happen is the head blows off when it gets warmed up. I'd just have to JB Weld it back on XD or put in a gasket. If I tried to use a cast iron or steel head then I would need to buy a real tap for the spark plug. That costs money lol I'm planning to use the spark plug or a bolt as a tap.
I have an idea. What if you were to put magnets on the compressor stator and try using it along with the coil to make an alternator. You could use it to maybe charge a battery and power an ignition coil to make sparks.Then you could have a more self-sufficient engine.
+LegitDIY that's a good idea! Maybe I will try making it a bit more self sufficient. I don't think the stator would make a very good generator. I'm thinking the windings aren't right. I could be wrong tho. I would like to try using a magneto tho. Make things a lot simpler.
Makerj101 Yeah. The thought crossed my mind about the windings but I'm no expert on things like that. I took apart an old garage door opener and disassembled the motor. It had a set of coils that looks just like that. I haven't tried using it as a generator but I have used it as an electromagnet. On the thought though. I think I'll try making a stator for it and try to use it as a generator this weekend. If it works I'll post the results as a reply to my original comment.
+LegitDIY that would be cool! Let me know how that goes. I do know that if you use a capacitor and do a couple other things you can get an AC induction motor to act as a generator.
+LegitDIY oh, that'd be near the end. Figure part 6ish. Initially I'll try continuous arc. If that doesn't work then I'll try a magneto from a weed eater. After hall effect sensor, transistor, MOSFET, and ignition coil.
ehmm, you should have drilled 3 holes and then join them together to make one wide port, because that piston doesn't have too much distance to travel. Other than that, awesome job!
Meh, you could tweak them after that, the main focus now is to get it up and running :) Oh, and for the head you might need to make a bit more extra space for the air to compress(not too much though) as I saw in the video that the piston goes flat with the cylinder. As for the intake gas-air mixture I'd rather go with some compressed air and a solenoid valve, which should be opened right when the piston reveals the intake port. You have to be extra careful though, 'cause the mix will be very flammable..Another alternative to that is to use propane, but you would still need compressed air to make the proper mixture... Just as a random thing, it would have been very interesting to use a diesel-like injector on that such as no more fuel would be wasted. Just like a diesel, the engine will take just the air from the intake, and then, after the piston barely passes the exhaust port, the injector sprays a fine mist of gasoline, which, hopefully will light in its entirety. That would make it waay more efficient, but also, overly-complicated, which isn't really what you're trying to achieve here ;)
And I also forgot, just DON'T JB WELD THE HEAD! use a proper thick aluminium plate, you can proably find one on scrapyard or something, and they should proably give one to you for free ;) drill some holes on it, drill another hole for the sparkplug and make a thread on it (this will be quite tricky) and then use 4 bolts to mount it into place and use some RTV sealant(you know that silicony black stuff which is good for making gaskets that can withstand high temperatures) and it would be far better :)
+Ramses I really should get JB Weld to sponsor me. Maybe they'd send me a 55 gallon drum of each component!! :D that'd be pretty darn awesome. I could make a whole engine out of JB Weld XD
How do you calculate/know where to drill the intake and the exaust? Like, the height of the holes on the cylinders. I want to make one as well, I also have a compressor like that!
Help! I know I'm really late but I want to make one of these and I can't find the exact timing chart you showed in the video. Can you please give me a link?
I can't remove the flywheel because the shaft its onto is hollow like a pipe and my flywheel remover doesn't work on it... help? Edit: Solution and other tips in the comments.
@@yigitdemir4604 Your piston really should come out one way or another. I removed the bracket that held the connecting rod to the crank, then i could push the piston all the way up which allowed me to rotate the crank and pull it out(after the flywheel was removed). Then i could get the piston out and start drilling holes. You could try to drill holes with the piston in(at exactly bottom dead center), but it could damage the cylinder and piston, no need to worry about scoring since the piston seals perfectly and lets you push the dust out from the top. Remember to mark where you drill and drill precicely. Its best if you get a 2 stroke timing chart to measure exactly where to drill holes. It took a LOT of time and work, but i got it to work somewhat, i use a reed valve instead of piston porting, which was a dumb choice really.
@@lengaming1651 i got the chart printed but when it says, for example, transfer port opens does that mean transfer port starts to open or its fully opened. By the way my connecting rod is one piece so i must drill very very precisely
You should of tried a slightly smaller intake/exhaust ports/holes FIRST and then continuing with the 4 small holes you drilled first instead of going straight to the larger holes. then continue to build the engine and test it so you dont loose as much cylinder compression!!!!!!!!!/power only then if it doesnt run should you step up the size of the holes. and see if it runs. and only do it in small increments so you dont ruin it from the start!
+realflow100 sound reasoning! My intuition says it would run far better with too lathe of ports than too small. Too small of ports would put a huge limit on rpm. Although it may increase the low end torque. High performance 2 strokes generally have huge ports while weed eaters and more efficient engines have smaller ones. It's good thing thing to consider.

The best explanation of 2-stroke engines I've seen.
A drill bit as a center punch? So that's what happened to our bits...
+Robert Berger thanks Bob! Haha yep
i am excited to see how this works out, i cant wait ,also good idea with the heat sinks as an head for the engine, they are perfect for it.
Well done with the 2 stroke diagram. Ive never really understood how it works but you explained it really well.
15:40 Almost said "Focus you fak!" and a bit later "good enough for the girls i go out with!" :D
AvE style :))))

Fuel air mixture in the crankcase?
Are you using drill bits for wood? Would they work somewhat?
