Very impressive project sir. I like that it is a true V8 not 8 engines bolted together with nothing else done. You have done a lot of work building that and I am so totally impressed. Thank you for sharing, Best regards, Bob from Virginia USA
I have great confidence in you and it's awesome my friend to see you getting it done❤️👍 You remind me of my Dad and his ability to fix anything anywhere anytime. He was a millwright for 30 plus years in a plywood mill
Instantly subscribed. I cant wait to hear it run 🤞 Edit.... holy crap theres a video of it running already. What an amazing piece of pure mechanical poetry. You sir are a master at what you do. I wish I had your skill and knowledge to combine 4 old Kohler k series cast iron engines into an inline 4 cylinder. Those motors were such beasts.
This is absolutely badass. I hope you figure out all the bugs with it. Also would be cool to run a full exhaust out of the back to see what it’d sound like
Keep going and do a V16. The sound of a V16 is utterly sublime. Cross plane V8's are good, V12's well they just sound like a couple of inline 6s really, but a V16 has this inimitable quality - brutal, guttural, visceral and most of all menacing.
Respect for this challenge of a home built powerplant. Love the project. Hoping for quad carbs in the future and sheet metal enclosure to route cooling air from the flywheel fan. See mentions of V16 and V12, yet the scream of a v10 F1 engine tickles the soul. Happy to subscribe.
I think cooling air flow is the fundamental flaw in this design. As long as he never runs it more than a few minutes it may be okay but it cries out for a fan and shrouding. I sincerely hope he can sort it out. I'm rooting for you, Lyckebo.
There is a fine line between Genius and Madness... And you sir are very much both. Great engineering and you are definitely crazy LOL That tractor is going to be a crazy ride. Good luck and cant wait to see the finished product. KF 😎👍
4:10 make sure that there is scratch marks. honing the cylinder walls so the oil can sit in the very small scratches. this is what my mechanic teacher told me if the cylinderwall is to smooth, then the oil cant stick to the walls of the cylinder
How about X format two stroke. All four rods are carried on one big end journal. Result is a perfect primary balance and almost zero torque vibration. It will need a low pressure blower for low speed operation. Once up to speed the gas flow keeps it going.
I swear to god if I had a mill that big.... I gut that thing like fish add some ball screws and a Nema 52 mount plates and I be making whole engines from Scratch lol never mind cutting old briggs apart 🍺🤣👍
I am a good mechanic however something like this would be out of my range, this guy is brilliant , but I am thinking back and my late father used to build model boat and plane engines and make up all the gearing and etc I'm sure he could have built something like this
You got a new sub here. Very impressed I can't wait to see how it performs. I bet that would make a great engine for a Small aircraft like a gyrocopter. Power to weight might just be impressive. A gyrocopter would give it great airflow to keep it cool.
You must have just started this channel because with this kind of content you should be at least around one million subs dude but hell yeah man keep up the good work
omg.. i genuinely never subscribe to a channel on the first date.. ..i mean view.. but this was so impressive i cant Not subscribe youve alReady proven u deserve it thanks for the video man, n channel really.. genuinely entertaining things to watch r actually kind of hard to find
When you were finding center, video behaved super strange, similarly to vibration detection algorithms. The rod was rotating and bending in a very strange way.
If u need any help I’m sure Roadking would be more than willing to help, he built an amazing inline 4cyl brigs as well as was working on a radial Briggs at one point.
Most engineers agree that a V6 is perfectly symmetrical and require less counter weights on the crank, so I'm curious why you went with a V8 instead of a V6 or inline 6?
As far as I know a flatplane V8 is also easy to balance, when the crankpins evens out eachother. A crossplane V8 needs more balancing. Thats what I have read, but I´m just a happy rookie. I made a flatplane crank and only removed the weight of the pistons, pins and the weight of little end of the pushrod.
I guess everything is possible but the B&S cylinders are very thin. They have optimized the molding so there is no surplus material. For me this was the easyest way to do it and the cheapest.
I had problem with the carburetor. It flooded and gas pour in to the front cylinders. I also had ignition problems so I ran it quite some time on the starter. When it started the front cylinders where washed cleen from oil and after ca 10 sek it stopped. Only one cylinder damaged. The cooling is no problem for now. I run it only minutes and after I can hold my hand on the cylinders. In the future I will fix something.
@@Desmouffe Have you thought of slightly opening the oil channels behind the oil control ring, they can be pretty rough sometimes on small engines, and extra lubrication on the cylinder walls for the inboard cylinders on each bank would be beneficial as those are always going to see the most heat if you do plan on running it for an extended period of time, perhaps you can come up with an oil squirter that can spray directly into the underside of the piston, for a man of your caliber I have no doubt you could scale this hurdle.
@@Initial_Gopnik I was also thinking of the issue of cylinder lubrication since those were designed as horizontal and splash lubed. Now standing up there isn't any oil splashing on the cylinder. And there isn't forced air cooling now. I know you're only doing short runs, but it won't take long to heat up. It might help to mix a little 2-stroke oil into your fuel.
So many air cooled cylinders in such close proximity? There’s a reason why they don’t do that. My prediction is that the middle cylinders will overheat, and that could be a serious problem. Good machine work, but a potentially seriously flawed design. Thank you for sharing.
Good eye. The block twisted. Personally I would have just used a zip cut disc on most of that excess aluminum casting and brought it down before milling
It's not homemade. But I have changed the motor and put in a frequency inverter drive. You need a lower speed when cutting metal. But it's to week. I need a real one
Looks neat and maybe you did it and did not show it on video but I did not see you put the circlip inside the piston on the wrist pin of the last cylinder made and assembled.
It can be a bit tricky to get them in place so I didn't want to waste video-time on it. And in the same time I did think that someone surely will notice that. And you did. But you can be calm. It's there....
@@Desmouffe And what about gaskets? So many air cooled cylinders in such close proximity? There’s a reason why they don’t do that. My prediction is that the middle cylinders will overheat, and that could be a serious problem. Good machine work, but a potentially seriously flawed design. Thank you for sharing.
@@G58 That's true. I have so many other things to do so the cooling has been forgotten. But I'm working right now on a system with two electrical fans. We will see where it ends...
@@Desmouffe Cool. See what I did there? British humour. The natural limit of an air cooled multi cylinder engine is either a V twin, or a parallel four facing the direction of airflow. I guess if you arrange a ducted air system to blow upward between the cylinders, you might possibly get away with it. I wish you luck. Peace
It looks like it will overheat and shake like crazy, And they already make flathead v8’s. Valves will end up sticking open from time to time probably. I just see too many problems. These engines aren’t even designed for an acceleration curve, as they more for steady state operation. Awesome work though. I just see so many problems with this.
It was a series of very unfortunate things. When I was working on the pulley change the tractor was jacked up in the rear. I saw a little puddle on the floor but didn't do anything about it fist. It was petrol. The carburetor was flooding despite it was placed higher than the petroltank. The ventilation hole on the fueltank was clogged so when the temprature in my workshop was rising a pressure was created. Since the tractor was jacked up the petrol followed the intake manifold until the last cylinder and there it found it's way down in the cylinder. Naturally I had also been tampering with the distributor so when it was time to test the engine it would not start and I ran it for a long time on the starter motor. When the distributor problems were fixed and the engine started the front cylinder was washed cleen from oil and ........ A long story but that is what I think happened
Maybe this time build actual headers? Not 4 into a 1inch pipe.not like a cheap lake style setup system, but maybe 4 5/8" into a 2 1/2" collector on both banks.
Very impressive project sir. I like that it is a true V8 not 8 engines bolted together with nothing else done. You have done a lot of work building that and I am so totally impressed. Thank you for sharing, Best regards, Bob from Virginia USA

That is an ingenious design and build, Sir. We’re all waiting to see it run!
wish people would think before they speak. just look at his channel lazy ass.
Technically It already ran...
@@shawnsatterlee6035 NO IT DID NOT!!
ngl he really let us down by not making it a v10 or v12, I would've loved to hear one of those run!
@@shawnsatterlee6035 _&yo
You are a genius. Only thing I could think is maybe a Rochester carburetor for more cfm's and a flywheel shroud and engine covers to cool it a little.
Thats what i was thinking need a way of keeping the engine cool while running
Quadrajet only puts in what the engine asks, maybe a good idea
I don't know what it is exactly, but this is the coolest thing I've seen in a long time in terms of out of the box thinking. I love this project!
Can’t wait for part 4 👍
Kick ass project. I can't wait for the next video! Thanks for sharing!

Sane here.
Don't cut yourself short. You can learn to do it too!
Am I dreaming? This is the best project on UA-cam! Excellent!
This is absolutely badass. I hope you figure out all the bugs with it. Also would be cool to run a full exhaust out of the back to see what it’d sound like
I love this and I'm so happy you're showing the building and process of making it all it's really cool man! I hope this gets put in something fun!

I can't believe this engine was design and engineered, kudos....looks like this power plant could power a small car legally on the road.
A very small car.
Great to see a video on the V8 Briggs! Glad to see its in one peice again!

Please...
Your videos are amazing to watch. Thank you for the great content you put out and share with us.
Put it on a go kart with a motorcycle broken engine as transmission for this engine... it will be insane and would get roof breaking views
Freaking love it.
Id like to see a straight 6 too
Interesting thought....

Small engine mechanic made a straight 6 if I remember correctly. V8 is going to be cool .
Roadking807 channel i think.
Nice! I've always wanted to see something like this. Like a modern day Ford Nail-head V8
This is amazing!!! Looking forward for more videos!
This engine is going to make an awesome sound I bet.
Wow! You and Allen would be the best of buds!
Great to see the cylinder machining
Sir you are a genius!
the front cylinders seizing might be a cold jug and hot piston. maybe fuel distribution . great work man!
It was other problems but now I hope I'm in control
Wow done the old school way all by hand no computer!
4:10 make sure that there is scratch marks. honing the cylinder walls so the oil can sit in the very small scratches. this is what my mechanic teacher told me if the cylinderwall is to smooth, then the oil cant stick to the walls of the cylinder
True
Once the engine is done you're gonna have to build a car to put it jn out of several cut up lawn tractors:) this is so cool
Kick ass project but I think need a fun to cooling the engine
This one needs zoomies and a 200 shot of nitrous.
Maybe even some trumpet style ends, just to make it loud enough to complement the build.
How about X format two stroke. All four rods are carried on one big end journal. Result is a perfect primary balance and almost zero torque vibration. It will need a low pressure blower for low speed operation. Once up to speed the gas flow keeps it going.

Love the build great job !
I would like to volunteer myself for testing this out on a go-kart....
Haha. That’s awesome
Gotta see this ! +1 sub for you 👍
Looks like a cylinder sleeve was not good idea. Was the ring too snug? Wonder if other rings are tight?
When you were finding center, video behaved super strange, similarly to vibration detection algorithms. The rod was rotating and bending in a very strange way.
That,s how it works
@@DesmouffeO-o-h. Never seen anything like this. It looks counter-intuitive, as if should not exist.
fastest mill/lathe hand Ive ever seen
Good shit. Love to see it.
If u need any help I’m sure Roadking would be more than willing to help, he built an amazing inline 4cyl brigs as well as was working on a radial Briggs at one point.
It was a four , I couldn't remember thought it was a 6. Him and small engine mechanic.
Yes, I follow them
The flywheel and starter motor is powerful enough for two cylinders. Do think you will have a problem with eight cylinders?
Clever, very interesting
I’m waiting to see how you are going to cool the heads and cylinders
I'ts coming, I promise...
Well done!!!
Been cool if he could of made an intake that would fit a 4 barrel vehicle carburetor
Man you need some air fuel ratio gages to set up the fuel.
ahh the good old cnc machine arm.
Gleder meg virkelig til å høre lyden av den😃
I hope you have solved the problem.
I think so. Future will tell. Brutaly...
Got my sub
Even in water cooled. the center two cylinders cook... air-cooled is 1000 times worse . This simply cannot prevail from and engineering standpoint
Cooling is a big issue and I'm working on that. If you want a powerful and reliable engine, buy one of the shelf. If you want some fun, build one.
Now to find it running.
Rolig ide👌

I guess everything is possible but the B&S cylinders are very thin. They have optimized the molding so there is no surplus material. For me this was the easyest way to do it and the cheapest.
Next do a Radial Briggs.
Why did it fail? Overheat? There is no cooling fan like BS has. What temperature do the cylinders run? Or is it a lack of lube to the cylinder.

It’s awesome, but you do need some better cooling. Axial fan along the vee? Cowlings to suit…
Yes, the cooling needs som work. I'm not sure how to do it yet but some kind of shroud.
Videos on the homemade bandsaw please, especially the motor and drive.
It's not homemade. But I have changed the motor and put in a frequency inverter drive. You need a lower speed when cutting metal. But it's to week. I need a real one

How is it cooled? Its an air cooled cylinder
Nice homemade flat head, i'm sure it will sound really good! What sort of exhaust are you going to run with it?
Flatheads are a flawed design. That's why Briggs and Stratton has a 3600 rpm limit.
