I would strongly suggest buying a real pair of laser goggles from a reputable source. Those glasses that come with cheap laser cutters are very hit or miss. A lot of them don't actually do what they need to do. At high powers it only takes a reflection of a reflection to blind you permanently. An enclosure would also be a good idea.
A friend had the chance to test a couple of those cheap ones you can find on aliexpress and that often come included that had accumulated over the years at his university lab.

@@bruhpopoppoop2759 Exactly. And folks often use them with quite powerful lasers feeling totally save when leaving the room would be more appropriate.

Now that was a hell of a high-energy episode; you had enough action in there for two or three videos but I'm certainly not complaining. I kept thinking "that will be it for now" but you kept on going. Can't wait for the next one.
That thing just keeps getting more impressive! And he gains more and more respect from me. As a machinist, I love watching him work, and come up with better ideas!
Its nuts to see how far youve come. In your tooling AND ability. Congratulations. Also, i drive a Magnussen supercharged 2006 GMC sierra pre runner. In the installation instructions it says in bold print to never use impact tools to remove or install the drive pulley. I know it says that about harmonic balancers and ive used impact guns installing those countless times with ZERO issues. However, as you know, twin screw superchargers have incredibly precise tolerances.
The "I hear you"actually came after me shaking my head (as I have done the exact same ;) ) I'm so glad that I have been here from the start of this project.
Your vids continue to inspire Me! I don't think I've ever been so excited to see a project that I had absolutely nothing to do with, come to life so bad.. Keep it up man!
The issue that you had with the supercharger is that one of the gears is not attached directly to the shaft. The one with the nut on it uses a collar that allows it to slip. When you use an impact wrench, the inertia causes the timing to go off slightly. I wrote a more detailed comment below if anyone is interested.
Hello from Holland, amazing work, but I have only one remark, throw away that Eaton supercharger and get a lysholm twins crew, the Eaton the lobes are touching each other, and the higher the pressure the higher the friction, the lysholm twinscrew the lobes don't touch, less friction, only disadvantage it needs higher rpm. And the people at lysholm are very helpful and maybe they will make you a small supercharger.
Ik had ook al een link gestuurd met die nabrander die Yamaha nu heeft bij zijn 2 takt motoren. Denk dat ie het te druk heeft. As in pressure 😅 Hoop dat ie je tip opvolgd, anders een hoop te herstellen.
Hi Alex. I just have to say that I totally enjoy your fantastic efforts and expertise in what you do with 2 stroke engines in general and that brilliant concept of the blown engine. It’s wonderful and amazing what you do with the workshop you have. Keep it up. Cheers Martin (Dublin). 👍👍👍👍👍
Every time your reminder comes up of a new video, I can't wait to see what you have done. The way you put this beast of a machine together is amazing, creating parts as you go. Can't wait to hear it start up and see what performance is achieved. Marvelous peace of work.
My experience with Nitro is from Harley racing in the 90's. Nitro is very explosive. We had to blow the engine out after every start. Change the oil after every run. Something as simple as a loose ignition wire may blow the engine sending scrap metal everywhere. This is a bomb. Be very very careful. Always error to the side of caution. That said. Very impressive build. I wish you the best of luck.
Been watching for a long time now, and I'm always tapping my foot as I watch 🤔....then I realised you have the coolest soundtrack of any video blog I know! Please give us a playlist ?😍
You might want to drill out a bit of mass either side of the new ignition trigger bolt to prevent vibrations. I've been laser cutting gaskets for ages - it's like magic. Nice music. And a handy tip: When using steel washers I always turn them so the rounded edges from the stamping process are against the softer material like aluminium or 3D-printed plastics.
After following the pip engine for what seemed a lifetime you have managed to build a far more complicated design in a fraction of the time looks like working part time is paying off for the viewers i for one am excited to see it start great work
Watching this come together has been fantastic, can't thank you enough for sharing it. It's like being able to watch John Britten craft his inventions.
21:30 nice press!! That 50cc continually evolves with your research, intuition and hard work it's truly remarkable watching this little machine grow into the nitro breathing monster of today. Thanks for documenting it.
Dont trust your eyes with cheap Chinese laser protection glasses, get some protection you know is thrustworthy! Can't wait to see the beast getting started, looks amazing!
How far you have come since those early days of peddling and struggling without the precision tools. I see a different 🌎 of technology and skill. Hope your other half appreciates your hard work.
This is some quality content!! You work 10 X faster than Binky. They appear to have become too reliant on patreon and unfortunately appear to be a one trick pony... You have so many interesting projects in line. You deserve every success
Now that it is assembled i see you make a number of buff horses, my only suggestion is instead of using a Wastegate valve use a Blow off/ recirculation valve, the wastegate valve would make sense if you plan to use it as boost control with a 3 port PWM Mac valve, that way you could use one pully and get or maintain a wide range of boost pressures at will.
I love your project. I worked with aluminum most of my career and you will love your new carbide tipped blade. Use a saw wax when cutting for the best cuts and life. Also try a tubular hack saw frame and you will be amazed at the difference. .
Taking a machined part to the CNC for moding the pick up coil. Hats off mate your getting good on that thing! I’ll have to make special orders for parts from you. Can u ship to Zambia 🇿🇲😎 impressive stuff
And just so you know im a steel worker i build a repair al types of things and but 2t racing bikes for hobby i run a drd racing with 88cc italkit 28mm pwk and MHR exhaust 26hp at the back wheel just waiting for rotor ignition for a bit more power
Love your videos. Congratulations on the progress. I'm sure your audience is much like me and fully understand the massive amount of work behind the scenes and share the same level of respect as myself. Downside is I loved the Laser cutter idea for gaskets so much I now need to get one too. Like you I brought a CNC mill and like you mine was a heap of shit. I have stripped it and rebuilt it with a 3.5kw 18000 rpm spindle and replaced all the electronics. Its been a fair amount of work but my god is it good now. I get mirror finishes on everything it seems and it eats steel for breakfast. I build chainsaw engines. My projects are not as ambitious as yours but I so hope this engine is a screeeeeeming success.
Why does it need a dump-valve? as soon as the butterfly valve of the carb closes, the mass flow will be drastically reduced. That's how it's done on carburated blown 4-strokes. You regulate the pressure in the engine's intake with the butterfly valve inside the carb, just like it's done with N/A engines.
I’m not sure about that supercharger, but on many I have used on cars it’s very important to put even and correct torque on all nuts/bolts. Otherwise case distortion can occur and cause rotor binding.
EDIT: I just continued watching and YES... using the impact on the pulley is what caused the issue with the supercharger... I have the exact same unit. Read on. I'm not sure if you sorted the super charger issue out or not... I had the same thing happen and know what the issue is. One of the gears is designed to slip on one of the shafts to make the rotors easier to time. They are both driven but one of them is allowed to move in relation to the gear if it needs to. IF you use an impact wrench or move the shafts abruptly, the timing goes off slightly and causes this issue. I have not been able to find an answer as to what to do in this case, but I think that it is supposed to self correct ... my belief is that the whole idea of the slipping gear is to allow it to self align, so it should do so if you run it 🤷♂️ FYI... Altho some claim that this unit can be used in either direction, that is false. It CAN be used in either direction, but you will not get full efficiency (not the full 300cc per rev). The outlet has relief cuts to aid flow and when run in reverse the charger will not discharge the full volume, as a result.
Hi ! You will have problems with that electric button...at high rpm the spring inside will stay close , resultig cutting rpm ! The disc valve will bend resulting in friction with wall case ! Do the math...how much pressure you will have on exhaust ...multiply with aria of the exhaust and will result too much kg force on the side of the disc !
Truly Sick, been following since Beginning. You Tease, Keep up the incredible Craftsmanship. Can’t Wait!!! Get that Monster, Compressing Fumes, Spitting FIRE! CANT WAIT! Thanks so much.
Could have started it in this video 😂😏 I've been in a hospital with GBS for a 3 weeks now, can't hardly move :( but today's video has made my day a bit brighter! Thanks for your content. P. S - your skills are improving each video and that engine looks beautiful!!
Make sure you leave some slack on those ribbed belts when the engine is cold. The aluminum will expand and make them extremely tight and wear out your bearings
OMG, so close, I really hope it works out. Just a thought, if you find the supercharger drags too much power out of the engine (it could draw more power than the extra power it makes and it's only a 50cc engine), perhaps you could consider a small turbocharger, the beauty of a turbo is it is 'free' boost.
What a beautiful creation my friend, absolutely stunning 😍 This is going to be a pure eargasm once you have it up and running and I for one seriously cannot wait, thank you 🙏🏻
Its a shame this engine newer was completed, The Rolls-Royce Crecy was a British experimental two-stroke, 90-degree, V12, liquid-cooled aero-engine of 1,593.4 cu.in (26.11 L) capacity, featuring sleeve valves and direct petrol injection. Quote Wikipedia: Subsequent single-cylinder tests carried out on the Ricardo E65 engine achieved the equivalent of 5,000 brake horsepower (3,700 kW! ) for the complete engine. That's 192.3 horsepower (143,4 KW) per liter of volume, and 800 kilos of engine weight. If blueprints on the E65 variant exist, its most likely that Rolls-Royce heritage organisation has those. If anyone had made a 20% sized engine, that engine could in theory be capable of 1000 horsepower and weighted 180 kilo. A 2% size would in theory be capable of 100 hp, and weight in at 16 kilos. .
A major problem you're going to fight is the stretch of that belt for the exhaust valve. As it heats up/rpms pick up it's going to stretch and throw your timing out of whack. You should also redo the header flange out of steel/stainless or titanium if you can get it. With it being aluminum it is going to kick off a TON of heat instead of keeping it inside the tube and right next to that belt you don't want that. Sure the steel/titanium would hold heat longer but the aluminum will heat up far quicker and throw more of it off. Hey Alex, out of curiosity, what's the oldest tool you have? I just brought home a wrench from my grandfather's shop. It's a 3/4 inch ratcheting box end wrench that you flip over to change directions. It's marked Ford 3Z-2034. From what I can find that means it's an original Model T wrench for adjusting the transmission.. How cool is that?! It's from somewhere between 1908 to 1927. Obviously it's not going to go anywhere.
Luckily exhaust rv timing isn't that critical, there's some leeway. Another good point against having the ignition trigger wheel fixed to that pulley. The aluminium exhaust flange is just temporary, need to get some material. Sounds like a cool wrench! Not sure what my oldest tool is, maybe a pair of shears. Nothing special like yours.
@@2STROKESTUFFING I love old tools (the metal ones not people) they just seem to have a soul of their own after many decades of use. I swear my grandpa's hatchet that was actually my great grandpa's does.. I should've cut my finger off with it one day and it somehow missed instead.. wish I could've gotten it, no clue what happened to it. I guess this wrench must've been my great grandpa's or even his dad's.. all I know is as someone that's only ever owned Fords, go figure I'd find a Ford wrench. :D
@@2STROKESTUFFING si senor. I'm still trying to figure out how the hell you're going to start it and how it's going to handle a blower with 5X the displacement of the engine... and how it'll make enough power to turn that blower and move the bike you want to put it in.. let alone you too.
Well what can I say Alex lol many lessons learned this episode you found some as we call it unskilled flesh lol and some how not to's but it's a learning curve and we are along for the ride. You amaze me buddy its a pleasure to watch your journey. Thank you and again I'm eagerly awaiting the next video because I want to see it come to life. Fantastic job as always Alex.
Did you even work on an engine if you don't end up with a shop tape wound repair(band-aid, plaster) Great video as always. Keep on being amazing. Nice hat :) "to maintain the same hand to body ratio...."
What a machine really nice to see it , but with this brute force engine I see few scenarios. 1. Everything will work and engine power will go through the roof. 2. Piston gonna melt :D will have to run mixture really rich to keep temps down 3. Not enough power to spin blower.
"I want to retain the same hand to body ratio for the rest of my life" lmao Great work as always, I am glad you are able to work on the channel and your projects more! You are a real inspiration, despite not really wanting to hand-build an engine. Keep on rocking!
I am really enjoying your projects and love the quality of the design and work. I think that you can make two claims now. The most powerful 50cc engine and the physically largest.
Don't worry about the cut finger, I have learned over time everyone on the internet is smarter than me, or so they say :-) love your go-at-it attitude to get shit done.
You can use a teethed pulley as tensioner on the inside if there's no other way around it. But yeah, one is usually enough if you don't build a serpentine style belt drive.
Would be interesting to see if you even need to gate off air, maybe changing pulley is enough. Remember to keep some cooling fuel and oil mix in the intake when letting off the throttle.
I'm enjoying your work more as you get into it. I was racing a Suzuki RM 250 grass kart in New Zealand. Used the Ignitech ignition on that one, with flat shift gear lever cut and rev limiting at 9,500. Also used to change ignition maps for various track conditions - "slow and slippery", "drying with some traction" and "holy shit that's fast!" Love your blues "between dialogue" music too!
my drill press once threw a brake drum acrost my shop from that point on I always clamp stuff in a vise when drilling on the press also I was thinking @8:12 could you balance that somehow I wonder so its smooth?
I worked in a metal fab shop that had used 3/8" square aluminum plate for the bases of air conditioner stands . I have watched and personally had 8" plates get caught on the drill when drilling the center hole and then spin up enough to break the 1/2" bit and send them on a flat trajectory until they hit something solid .
Yes! it's great to see how fast it all came together in the end. I've got a better idea than a couple of bits of wood to make a test stand, BUILD THAT BLOODY DYNO!!! :-) Nice work as always Alex, thanks.
This thing is just fun to look at!!! Also, The situation you ran into with the supercharger is a very common one, what you suspect happened is exactly what did happen. In every single one of the blowers on my FED there are shims whose only reason for existence is to solve that exact problem... axial shit=clocking shift...
I would strongly suggest buying a real pair of laser goggles from a reputable source. Those glasses that come with cheap laser cutters are very hit or miss. A lot of them don't actually do what they need to do. At high powers it only takes a reflection of a reflection to blind you permanently.
An enclosure would also be a good idea.
Yes. Of all the things in my garage this laser scares me the most.
A friend had the chance to test a couple of those cheap ones you can find on aliexpress and that often come included that had accumulated over the years at his university lab.
None of them offered any meaningful degree of protection to the wavelength they should have.

It's a 3/4 inch ratcheting box end wrench that you flip over to change directions. It's marked Ford 3Z-2034. From what I can find that means it's an original Model T wrench for adjusting the transmission.. How cool is that?! It's from somewhere between 1908 to 1927. Obviously it's not going to go anywhere.
Luckily exhaust rv timing isn't that critical, there's some leeway. Another good point against having the ignition trigger wheel fixed to that pulley.
The aluminium exhaust flange is just temporary, need to get some material.
Sounds like a cool wrench! Not sure what my oldest tool is, maybe a pair of shears. Nothing special like yours.
@@2STROKESTUFFING I love old tools (the metal ones not people) they just seem to have a soul of their own after many decades of use. I swear my grandpa's hatchet that was actually my great grandpa's does.. I should've cut my finger off with it one day and it somehow missed instead.. wish I could've gotten it, no clue what happened to it. I guess this wrench must've been my great grandpa's or even his dad's.. all I know is as someone that's only ever owned Fords, go figure I'd find a Ford wrench. :D
I'm stupid, ignition timing will still be affected. Might have to relocate the trigger to the crank.
@@2STROKESTUFFING si senor. I'm still trying to figure out how the hell you're going to start it and how it's going to handle a blower with 5X the displacement of the engine... and how it'll make enough power to turn that blower and move the bike you want to put it in.. let alone you too.
Looks the part, very nice.. cant wait to see some numbers.
Numbers wot? Pretty sure the engine number reads 'FKN OG'
@@realryder2626 seeing is believing. Here we race 50cc 18Hp is standard.
Your channel just gets better and better my friend, keep rocking..
Well what can I say Alex lol many lessons learned this episode you found some as we call it unskilled flesh lol and some how not to's but it's a learning curve and we are along for the ride.
You amaze me buddy its a pleasure to watch your journey. Thank you and again I'm eagerly awaiting the next video because I want to see it come to life.
Fantastic job as always Alex.
"It's quite the contraption". Yes, and you sir are quite the designer, engineer and fabricator. Great vid as usual.
Damn project Binky,...gotta say that I loved the laser cut gaskets... Start next episode with the sound of this thing screaming... please 😁👍🇭🇲❤️
Did you even work on an engine if you don't end up with a shop tape wound repair(band-aid, plaster) Great video as always. Keep on being amazing. Nice hat :) "to maintain the same hand to body ratio...."
😁👍 Thanks!
What a machine really nice to see it , but with this brute force engine I see few scenarios.
1. Everything will work and engine power will go through the roof.
2. Piston gonna melt :D will have to run mixture really rich to keep temps down
3. Not enough power to spin blower.
"I want to retain the same hand to body ratio for the rest of my life" lmao
Great work as always, I am glad you are able to work on the channel and your projects more! You are a real inspiration, despite not really wanting to hand-build an engine. Keep on rocking!
Love the fast forward feature with the music as it shows us the the not so fun stuff quickly 👍
I am really enjoying your projects and love the quality of the design and work. I think that you can make two claims now. The most powerful 50cc engine and the physically largest.
😁 Thanks!
What an absolute unit! I like two strokes for their simplicity. 🤣
Awesome music choices. Really enjoy watching these.
I love it. It looks like a piece of experimental lab equipment. I can't wait to it starting.
Great to see the progress, cant wait to hear it!
Should be proud of what you have built with that it’s looks proper man! Nice one
A binky ending LOL you tease, thats an excellent flame thrower you built there
Don't worry about the cut finger, I have learned over time everyone on the internet is smarter than me, or so they say :-) love your go-at-it attitude to get shit done.
Love your videos, please more. As a great fan of engines you amazed me. Please never stop.
Your best edit yet !! cant wait to see it start and run, just hope it meets expectation
So cool to see people doing what they love I hope you go far with this channel
You can use a teethed pulley as tensioner on the inside if there's no other way around it.
But yeah, one is usually enough if you don't build a serpentine style belt drive.
Excellent...you are truly the mad scientist of two strokes 😎
Excellent music choice and editing on this video!
Would be interesting to see if you even need to gate off air, maybe changing pulley is enough.
Remember to keep some cooling fuel and oil mix in the intake when letting off the throttle.
Leave us on a “Binky ” cliffhanger? ……I like ur style 😂
Thank you for sharing your amazing work, this engine is a beautiful work of art.
I seriously wish I was a 16th as smart as you are! Your two stroke builds are out of this world!!! Great stuff man!!! By the way I do love your hat!
We call that Amazeballs over here. Can't wait for the test run and power numbers
I don't know what's more amazing your engineering skills or taste in hats!
And music
The bloke that sent the box of useful parts - legend.
You amaze me with every episode!
It looks soooo Good , can not wait for start-up ...with or without Flame Action !
I'm enjoying your work more as you get into it. I was racing a Suzuki RM 250 grass kart in New Zealand. Used the Ignitech ignition on that one, with flat shift gear lever cut and rev limiting at 9,500. Also used to change ignition maps for various track conditions - "slow and slippery", "drying with some traction" and "holy shit that's fast!" Love your blues "between dialogue" music too!
my drill press once threw a brake drum acrost my shop from that point on I always clamp stuff in a vise when drilling on the press also I was thinking @8:12 could you balance that somehow I wonder so its smooth?
I worked in a metal fab shop that had used 3/8" square aluminum plate for the bases of air conditioner stands . I have watched and personally had 8" plates get caught on the drill when drilling the center hole and then spin up enough to break the 1/2" bit and send them on a flat trajectory until they hit something solid .
Yes! it's great to see how fast it all came together in the end.
I've got a better idea than a couple of bits of wood to make a test stand, BUILD THAT BLOODY DYNO!!! :-)
Nice work as always Alex, thanks.
Thanks! Just received some one-way bearings for the dyno, it'll get built asap.
Nice to see how much your cnc programing has improved. Good job man your doing well 👌
Awesome production. Great music and it’s very pleasing to look at! Thank you for a very entertaining video.
This thing is just fun to look at!!! Also, The situation you ran into with the supercharger is a very common one, what you suspect happened is exactly what did happen. In every single one of the blowers on my FED there are shims whose only reason for existence is to solve that exact problem... axial shit=clocking shift...
😁👍
