The flow will be way more efficient if you get water guides in the channel to make the turns flow better. Very nice project!

True craftsmen like you are far and few . Accept your mistakes learn from them and know more when everything is said and done .. Great job

I want to do the same as this guy, my dream to live off grid in the uk

Great job kris 👍

Fantastic!

Круто !

Still looks awesome... Keep it up brother

Great video Kris, and love your transparency

Serious question, running the risk of condemnation..... buuuut...... as you're technically the manufacturer and designer of this product, do you not need to comply with HSE regs, i.e. guarding rotating and moving parts? Believe it or not i dont think a locked door would be sufficient? Im only asking as a fan, i love the channel and wouldnt want you to be exposed to legal action or obviously cause an injury! Best of luck, keep it up!

Pipe or partly hollow shaft would be stronger and stiffer.

Absolutely grade A 10/10 series. If I ever want to build one, I'll be coming here first.

Each system in Universe is as strong as its weakest part.

Ladies, would you like if I brought you here, or would you need my place to be on the grid with money?

A swiveling lifting arm that drops into that dog hole on your car lift would be easy enough to fabricate. I bet something like that would get a lot of use for moving heavy stuff around and onto your work bench

At present if the water wheel overspeeds the proximity sensor will send a signal to drop the inlet board and reduce the flow rate. I assume the inlet board would have to be manually raised to bring the wheel back up to its optimum speed. Just a suggestion At present the inlet board is either open or closed. You could engineer a device to automatically adjust the height of the inlet board based on the flow rate. The inlet board will have intermediate positions. I think that would be a big improvement. I hope I have explained myself so you understand

Уважаемий мистер Крис ... Ви говорили 182 минути, а ваша вертушка вирабативает только 1 кВт ... Ваша производительност ето 1000/10800=0,1 ??? ...

I've been watching your saga for a while now. Glad to see your customer hanging with you. You will get it right.

Ciao. Non condivido le tue scelte estetiche, ma è la tua casa e quindi mi va benissimo così. In ogni caso sei davvero bravissimo in tutto quello che fai. Sei davvero bravissimo. Complimenti. Aspetto sempre i tuoi video. Bravissimo

cool project

proper fix. Good job!

You don't need to apologise for having bucket loads of integrity Kris, you owned up to the mistake and fixed it. A great project!

Fantastic, just binge watched. Should be on TV! Better get back to work!

Hi. If gearbox isn't inline with shaft it will happen again .

Great project, constant 1kW! Every house should come with a river 😀. Kris, noticed the forks on your digger bucket, made or bought? Very useful addition 🤔

Kris, this a big bummer. But you recovered very well and made it as it should be done. Looking at the clean fracture of the shaft I think it's a combined failure. The welding started a defect on the surface of the shaft and then the dynamic loading of the shaft broke it by fatigue during running (the crack progressed by the dynamic loading). I think I mentioned I never weld to a shaft. I always use the compression collets and sometimes a keyway if the counterpart needs a keyed connection. These are also prone to dynamic failure because the corners of the key way are stress risers too. The collet solution is much stronger than a keyed way and doesn't compromise the ideal shape of the shaft itself. If you're interested in this stuff look up Wohler's graph who discovered it when trainaxels broke way below the static load capability. Thank you for sharing your journey and approach. It sucks but shows the real person you are and clients will think the same. For a great future ahead. Best! Job

That entry door looks to me not wide enough 😮Your little Mitsubishi barely made it through. With door frame etc. you might struggle to get any vehicle inside.

Great opportunity to learn is every little mistake. Good job! Btw. IP camera looking on critical components would be handy, wouldn't it?

I would be happy to buy a solution from you. The difference between a good and a bad company is how they fix their mistakes. You do it the right way.

Is that a 16 amp plug with live pins on the turbine side? Should that not be a coupler into an appliance inlet? Otherwise the pins would be live when the turbine was unplugged on load?

Great fixing of the wheel section. You are amazingly talented man. 🐻🙏🇺🇸

welds often introduce stress raisers in steel. Even manufacturers get that wrong and weld something in the wrong place.........like I saw once on a heavy road transport semi-trailer.....they welded a mudflap bracket across the bottom horizontal chassis strap of a semi trailer. It lasted a few years and then the strap cracked through at the weld.

For what it is worth, during the 'incident' at Three Mile Island, everybody did what they were supposed to do. The procedures were at fault. And so, sometimes big companies make mistakes too, because they didn't have enough information. I expect I will get a lot of flack for this comment. Everybody followed the procedures.

So glad it was a waterwheel and not an elevator. You do great work, sometimes things happen.

I don't know if you did this but I have seen so many people weld on youtub after done welding many of them they put water on the weld to cool it down biggest mistake crystallized the weld the second it touches it

Mistakes are the best teachers and if you learn from it it is not a mistake it is progress ! Sorry it happened but the knowledge gained is priceless !

Id just like to point out that all of his assistants have either been screwing since the early hours or stripping all day in the mud.....

LEGEND

I'm no metallurgist but done a decent amount of welding in my life. Fully agree with your diagnosis. I know its annoying for you but I like seeing other peoples things fail, because that's how you learn (learning from others mistakes). Even moreso when you know its been built by someone smart who likes over engineering things. It makes the failures more juicy.

Salvador DALI approves

Great to see the engineering gone into this and see it working. Please get some safety glasses when on the lathe. Only one set of eyes.

Well learning from own mistakes is painfull but most effective. From the engineering point of view the problem is just the load cad of so called Circumferential bending. That's why it is absolutely forbidden to weld on railway axles, which have the same load case. Your final sollution is the right way to do it. Cheers Sven

Fantastic work

@KrisHarbour - Even though the previous shaft weld was not done properly, it WAS overbuilt. So I suspect that the main reason the shaft failed was the constant small flexing of the shaft due to the Belt Drive creating an offset and cantilevered load. No doubt that is part of the reason why large hydropower systems use Direct Drive. Perhaps your future designs will use Direct Drive, or at least reduce the cantilever length? Anyway, cheers on a successful repair. Best of learning and luck on all your endeavours! 🙂 P.S. - How long will it take this waterwheel to recoup its cost? Both the customer cost and the cost to you, considering the _new and improved_ design?

I've used loctite on taper fittings and bushings sometimes. Good job. I especially like the upsized bearings.

Great video. The shaft failed at the stress concentration where the hub was welded on. The weld produced a heat affected zone that weakrned the mild steel. The drive side is Subject to torsion bending and shear stress. It would be best to calulate the von mises stress at that point and add an allowance if 2 ir 3 for the reversing bending stress. If you know the wheel stall torque, wheel and shaft weight and cantilever overhang the stress can be calculated. If you sill get problems I suggest placing the belt drive between the bearings rather than overhung as this will reduce the bending. You could also place the generator above the drive do the belt tension increases with the water load.

Kris, what really caused the rotational assembly to fail? Two possibitlies that have not been addressed: First, the water wheel frame sits on 4 concrete pads (as shown at the start of the build) which will move independently leading to oscillation. Second, the wheel should be accurately balanced.

If I was lucky enough to own somewhere where I needed a water wheel, I’d certainly only want you to install it, Kris! Here’s to the next one!

in ten years he'll be building a tree house for a president

For what its worth, your achievements really inspre me to get cracking. Watching is very relaxing no american drama, just quiet excitement. Well done lad

Hi I’m a coded welder, just be careful with the width of your welds, with Tig keep them less than 10mm the narrower the bead the lower the heat input, we did a few jobs where the steel was in a high stress area and had relieve the stress with an annealing run. Also if you google heat treating with gas and oxygen, there’s a heat chart to indicate temperature
