Full Power! Full Speed!! Vintage Engine Drives Giant Wheel... 

Just put up a sign "This is a pass fail intelligence test. Losing life or limb is a fail."

This is amazing and super terrifying at the same time, I can't wait to see it hooked up to the slicer. Maybe you can make an enormous salad? :) Keep it up Tim!

Great work and wonderful to see it working at speed. There is a high degree of safety in having a machine that looks you straight in the eye and says: "Every part of me will kill you or mangle you horribly if you don't act with care and respect around me."

Tim please treat this machine with the utmost respect. You have a lot of kenetic energy in that wheel. If the belt was to fall off and get caught up in the wheel or engine,IT WILL pick up either the engine or wheel or both and hurl them all the way to Cork. Please please please do your research into the forces involved.

Yay, New video!

This construction looks really similar to the machine that stands around at the tractor meet in our town, built by the Herforder Motorenwerke. The only difference is that the engine is bigger and slower, and that a second belt powers a big generator, but it also has a momentum wheel, all while standing on a trailer. Fantastic build you have there, especially on the engineering side.

You still need a micro adjuster mechanism for the belt on the engine mounts. Make the engine frame mount to the floor capable of rotating the vertical axes by a threaded bolt and lock nut.. Think of a bench mounted belt sander - how does it keep the belt on? By moving side to side the non driven roller.. Just gives a little movement and crucially stops the edges of the belt fraying when it runs off.. Which it will..

Making the pulley convex is the right way to go, it is based on the "Hunting" principle where a flat object like a belt will automatically avoid going off the sides of the pulley and will always stay on the clown of the pulley. Train wheels are a very good example.

Did a good job Tim. I guess I should have said that at low speeds the belts tend to wander a bit more than they do at high speeds. They are designed to be run at the correct speeds, which is why old timers will tell you to never slow down the machine as that is how accidents happen. Either way super job and it looks like it will work. I am damn sure that you have more than enough power and you should not find any slipping.

Really a wild machine. That’s a lot of energy stored in that fly wheel. Thanks for sharing your build. A pleasure to see. It must be truly awesome in the ‘flesh’.

It really makes your realize just how dangerous those old belt driven workshops were. Well done!

What a great feeling! It’s like seeing one of your children grow up and graduate. Congratulations, I can’t wait to see it shave wood. You’re building a complex, integrated charcoal making system from scrap! Ha, Ha who said adventure has disappeared from the world.

Tim is doing his own, second industrial revolution!

So, so interesting, you are another Tim Hunkin, a now rare, British eccentric inventor 👏🏻👏🏻👏🏻

Always such an amazing sound! I do have to say, that after you expressed concern in the belt possibly getting caught someone, you still passed the camera under it. But what a fantastic beast you've made!

How can something so beautiful also be so terrifying?! Fred dibnah would have loved this!

A totally addictive watch, i can’t wait for the next episode.

Honestly haven't been so excited about a youtube channel for years. Past few months of seeing this absolute monster of a machine come together has been brilliant, and I'm so happy when I see a new video come out. From the garlic harvests and railway improvements to this, it's been a fun ride, and continues to be so!

It's so satisfying to watch this genius at work. A real inspiration for sure 😃

There is a whisper of standing in the early 20th century here some where. Keep it up tim.

Well done. You are getting there, Tim. It gets more interesting and exciting with every video.

Well done Tim ! Most impressive, rub a piece of wood on the spare engine flywheel to slow its down if you get bored waiting for it to stop.

I do love your videos Tim, in fact I don't mind putting it out there I've grown very fond of your positive attitude, ingenious solutions and fabulous (really, really fabulous) narration. The trouble is, each time I think we've reach peak risk, it goes another level higher: no laxatives required here I can assure you! There's just something about this wheel, and it is the most amazing build, that terrifies me. I'd hate to see on the news that there has been a bizarre accident involving a flat belt, an impossibly large, heavy wheel, a smokey old engine and bits of man, donkey and dog.

I wish you had way more subscribers. Always a hoot. Thanks. Every time you add a complication to the Contraption I think the exponent of risk factor increases. Although it could be a logarithmic scale. Be safe, Be creative and have fun. We do not know our life spans. Enjoy it whilst you can.

Keep movin', movin', movin' Though they're disapprovin' Keep that weel movin' Way out west! Don't try to understand 'em Just rope 'n' throw and roll 'em Soon we'll be livin' high and wide My heart's calculatin' True love will be waitin' Be waitin' at the end of my ride 😁

What a terrifying monster…..eager to devour whatever it can grip.

I'm so excited i nearly wet myself giggling with glee as the wheel spun up.

I agree with you. It is terrifying. I love it! I can’t wait to see what is going to happen next. Cool project.

Well that's down right impressive! Cheers Terry from South Carolina USA

Absolutely superb. “The clunking adds drama” 😂 I think I’d want to try and stop it nevertheless.

Tim! Would be soooo nice if you could do a video with just the engine being started, then clutch engaged, then leave it running for a minute or two, but without the slicer, and also without the clunking sound! Would be so cool to hear all of that!

I'am glad you see broken bones too Tim. Please be careful. Cheers 🇨🇦

Brilliant, I'm with you get it working 1st, there is a lot of R&D going on here and its not like your in the middle of a factory or anywhere crowded. You must be really proud of you achievement so far. 👍

I am always amazed how creative you and your projects are. Absolutely stunning

Making ideas real. Not so easy but you are brilliant

Amazing - but Blimin heck you can see how industrial accidents could happen! once it's up and working some nice big bits of ply or corrugated iron covers over most of it, so you can't slip and fall into that wheel!

Awesomeness at its best. I’m keen to see the chipper you’ve got attached. It will be flawless with all those moments of inertia you’ve now got.

What a beautiful yet at the same time terrifying machine you have built there Tim. I really enjoy watching you build it and can't wait to see the final assembly with your charcoal grinder working.

(not a criticism) WHEEL OF DEATH! WHEEL OF DEATH! ... Something I recall from an acrobat show with this huge rotating contraption. That is beautiful! Can't wait to see it powering the the Chop'n'grind 3000.

Hello, to keep the belt in the center of the pulleys, the surface of the large wheel must be rounded like the motor pulley, otherwise nothing can prevent the belt from going to one side or the other. It is a physical phenomenon that was well known to the ancients who built the engine. Good luck to you, inventors! I love your work!

Bonkers with bells on. Well done!

More often than not belt tension pulleys are placed on the slack side of the belt system. It is more forgiving of misalignment that way. You can also get more belt contact with the drive pulley if the tension pulley is placed close to the engine.

We had a Massey-Harris 33 and 333 on the farm and used the belt drives to drive a few implements up through the late 1960s. Mostly to crush grain or shell corn

To make it impossible for the belt to fall off when disengaged, just build a simple guide for the belt at the points where it runs onto the large wheel and the engine pulley, basically like the one side roller at the engine pulley but on both sides of the belt. As long as it doesn't rub constantly on the belt it doesn't need to be a roller, a simple round bar or a water pipe will do the job.

all the planning and staring at it with a cold beverage has paid off thats working splendid.

I wonder if, in a pinch, spinning up the big wheel manually with the belt under tension might get the engine spinning quick enough to start.

🚧🚧 You are a Genius Sir and Great Team Work 😇😇👌👌👍👍🍻🍻🚧🚧

So glad it's all working out, it is a marvel to behold. Well done.

This is amazing! Keep up the great work.

You are absolutely right about not using the flanged pulley. Every time I used one as a kid playing with stuff, the belt would always, always ride up and over it unless the alignment was just about perfect (but not absolutely). I learned about crowned pulleys when I worked on conveyor belts, they are the industry standard and definitely the way to go when working with belts.

Marvelous, Tim!

This is frightening and awesome! Good work!

Brilliant. Absolutely brilliant.

I love this do-it-yourself videos. In germany, people are just used to buy everything new instead of creating and building stuff by themselves and maybe reusing old parts. I really looking forward on how your project will turn out in the end. Keep up that great work.

Early Augerian period, cracked me up! 😂

Good to see that Health and Safety haven't prevented another useful creation. Keep it up. We didn't get to the Moon without losing several exception Astronauts.

This is so awesome and absolutely terrifying at the same time. I love it!

Tim and the infernal machine ..... Wow

You're having way too much fun Tim, glad to see it. Wonderful watching this in action, nice job! I'll be waiting to see the charcoal cruncher in action too! Be safe, cheers ☸

Superb progress. Has all the right sounds and wobbles beautifully; just as a proper machine should! Waiting in anticipation to see her earn her keep. Thank you as ever for posting and giving an old dinosaur such enjoyment.

Don’t let health and safety anywhere near it. Make a no-go area of six miles around your home. I think for the sake of your engine, you should start the wheel spinning outwards. That way, if it slips it’s moorings it will speed off out into the field and not ruin your wonderful old engine! Brilliant work. Mill factory owners of the 18th C would be proud of you.

Fantastic news Just so happy for your team Tim will be watching later it’s good for our health.You should be so proud love what you do Tim .Good luck 🍀

Awesome. Even by your standards that thing is terrifying.

Amazing ingenuity...I love the tensioner solution. You are correct though, in its present state it is extremely dangerous. I'm sure you will soon have it made safe with guards................although ( I reluctantly point out) your exposed wiring on the lathe motor could invoke that age old axiom "one flash and you are ash) Please keep posting. I love your other channel as well

Absolutely brilliant to behold, I was positively on the edge of my seat when you cranked it up!!! Beautifully done. Make sure to keep the wood well treated so it doesn't shrink an crack.

the mad professor strikes again, nice one.

Wow! Such a beast, and yet your ingenuity is managing to keep it under control. I love your forethought and trouble shooting skills. Thanks so much for bringing us along on this fantastic adventure! Looking forward to seeing this whole production line operating. Stay safe. Cheers! 👍

I’m amazed at the thoughtfulness you put into the build and the narrative you add. Well done. From a usa backyard engineer. I appreciate your problem solving process.

It looks like an industrial revolution under that roof with the old engine, the belt drive and the railway in the background.

The frame of that wheel has an awful lot of flex in it for the forces on it, and not just your tensioner.

You finally made a wheel to match with your introduction video tim wood workers use a rasp file if you have one you can make a wide groove in the wood so the belt can fit inside to prevent it from sliding

Scarier than hell! Well done!

Big moment! Exciting stuff!

Good to see it working this great :D Fantastic work! 😎👍

Amazing Tim it really is

I’m always impressed how you make do with whatever is at your disposal. It’s very inspiring sir!

Wonderful!

Fantastic! When something that large doesn’t come lose and take off across the countryside flattening 3 to 5 of the neighbors sheep and continuing on to cause the postman to abandon his duties and flee for his life…it’s a good day!

Great video...👍

How Dickensian. You have you own Industrial revolution here. All you need are some workhouse children to get caught up in the machinery.

That looks so neat spinning at speed.

Most exciting video you have ever released

In a world in which nearly tool seems digital, it is refreshingly terrifying to see an ingenious mechanical solution to a real-world needs like heating fuel and fertilizer. Bravo, sir!

This channel has more cliffhangers than a Netflix serial killer documentary. I’m buzzing for the next video already

I, too, am amazed at just how much momentum is stored in the engine's flywheels. Enough to turn the giant wheel up to speed!

Love your videos

I'm presuming also that a safety cage will be constructed around the whole contraption.. Maybe a metal frame with a big sheet of steel mesh to at least 6ft around the wheel.. If the belt comes off or snaps... Where's it going if it gets wrapped up in the wheel bearing area.. Its going to flail around HORRENDOUSLY until it stops.. You have to cage it in big lad, not only for your safety but for the uneducated that dont see the danger

Incredible! Congratulations, I really hope it does a good job. 😊👍

Tims whirling wheel o’death. Love it, well done 🙂

Brilliant love the sound of that old Bamford Engine.

Just awsome. I can only imagine how terrefying it is to test and adjust this contraption. But the outcome is marvellous as always. Keep up the good work

In one of your last videos I suggested building some sort of clutch, and you said it would be too complicated and infeasible. And now here you are building a clutch 😄 I love all the mechanical solutions you come up with to make work easier on the farm, keep up the good work! If I had a shop like yours I would practically live in there 😂

This reminds me of the inventions you would see in Wallace and Gromit claymation cartoons.

Thanks Tim

That looks amazing guys top job.

It all looks a bit scary, but I'm sure you all are aware of that :) I admire all your creative solutions to all the problems the shows up. It's brilliant.

I'm really hoping you go on to collect the wood gas from the charcoal process and use it to run the standing engine. How wonderfully circular that would be.

Amazing, but I would not dare to come closer than 20 meters when in full motion. Absolutely terrifying beast! Please be careful.

This is terrifying! What a sight!

I cant wait to see it put to work
