guys who can build stuff like this blow my mind. I'd rather watch this than some guy chasing a ball any day.

Not only gets upvote for the awesome build but also for letting us hear the sounds of the saws, grinders, arcs & whatnot without having crappy dance music or some such drowning it out.

I love these kinds of videos. no stupid narration, no god-awefull music, just two hands, a shit load of powertools and their (slightly and tremendously sped up) sounds. making something that i myself do not have the knowledge and skills nor the immediate use for.

Man you are a freaking wizard! Appreciate your knowledge of tools and machines! Never think about chain driven diff!

VERY IMPRESSIVE!!! That would be perfect for so many other projects!! I can't wait to see how you use it.

That was amazing to watch, a lot of thought and accurate measuring went into that one ! that looks like an ideal dif for a chain driven bike trike ! With the disc set up it looks like the jag 4.2 rear end i was using for a rover v8 trike i was building some years ago, that would have been ideal as a engineered minimised alternative as had to cut down the length of the drive shafts to fit 15" wide back wheels ;)

Thanks for this... I'm building a very similar design of diff, but at a much smaller scale... It's for an HPV/ small EV with a power of under 2kW... My output shafts are 12mm in diameter, the outer casing is 70mm in diameter, with only 2mm wall thickness... You validated a lot of my design choices!

Oh wow that's some serious work .. you make it look so easy . I'd guess a lot of planning and thought as well as precise measurements. Can't wait to see part 2 .

I really appreciate the time you put in on these videos. Thank you.

This is one of the best channels on UKposts. Love watching this guy make all this stuff. Every videos is interesting

You sir, are a first-class engineer, there is no doubt in my mind about that. Brilliant job.

I had to watch this twice it was so amazing. It looks like your diff is leak proof so you might be able to put diff oil in it. When I did mine on my trike I had the prop shaft input flange cut into a sprocket but then I had to also use a bevel gearbox from a farm implement ( Rated 70 HP). That was ten years ago and it's still going around England somewhere.

You do some DAMN FINE work my friend, this is AWAZING.. Thanks for the video, I loved watching it...

This is art! Amazing. Please keep sharing your work. 🙏🏼

Cub Cadet lawn tractors used small Chrysler automotive diff assemblies for three decades. the rear axle/gear box assemblies have been a favorite transplant part for builders for a long time.

I’ve been thinking of making this exact design for ages! Just went live axle for the buggy instead. LSD or locker would be so cool to have

Профессионал ❤❤❤ Можно часами смотреть на ИДЕАЛЬНУЮ работу МАСТЕРА !!! ИНСТРУМЕНТ ЗАЧЕТНЫЙ !!! РУКИ ОТКУДА НАДО !!! УСПЕХОВ !!!

Some of those scenes remind me Iron Man when he was building his suit! Excellent work.

You're a genius Sir. What an amazing work of art.👍👍👍👍

можно уменьшить площадь фланцев крепления тормозных дисков. это снизив общий вес, инерцию. балансировка корпуса лишней не будет. отличная идея и Великолепное исполнение. Мастеру Уважение

Классная работа! Талантливый механик!!! Респект!!!!

Very nice job! Well made and compact size!

IMPRESSIVE! There is nothing else that needs to be said. From video idea, picture quality, sound and editing. All around one of the best video I've seen here on UKposts. Be proud my friend, your talents go far from just what you do in the garage

I need one of these for a trike build I'm working on. Perfect 👌

I started watching this to get an idea how to build one myself since I wanted to build something that requires one for couple of years now, I think it might take some years still to be able to build one like this. Impressive! Good job! Maybe one day I'll use this video to actually build one.

This is art! Amazing. Please keep sharing your work.

that would make a sweet drive for a miniature tank or something similarly tracked , awesome engineering

With great interest I saw your design of a chain-driven differential. You did a lot of technical operations to make the vision of this device come true, congratulations 👌.

Love it !🥰Especially the inboard brakes ! Thanks for sharing 🙏

I will now shamelessly steal this for my next build. Thank you.

I just need this for my project! when i get money later. I will be in need of your amazing skills

Мощный механизм отличный технический подход, спасибо за видео!

Pretty ambitious and impressive build!

Great skills involved in the project.

Heat should not be a problem since there is no hypoid (ring and pinion). You should consider adding a ounce or two excess CV grease. It will find its way around as the spiders and side gears rotate. Then you can rifle bore one of the side flanges to vent into the CV without worrying of cross contaminating the lubricants.

Excellent job ! 👍

Props to your skills. Thank you 🇨🇦

Felicitaciones! Excelente trabajo!! Espero ansioso la continuación!! Un abrazo! Germán, Montevideo, Uruguay.

Nicely done. Reminded me of me. That was a cool build.

I love your work! ,I hope to see more soon!

24 hours in a workshop like this would be heaven

If i didn't just spend a whole lot of money on kart parts, trike parts, steel and then save for a couple more years, i might of had enough to make a tenth of the down payment needed to buy a lathe so i can build a differential. Thanks guy, i truly feel inspired 😅

Really nice vid thanks for showing us! P.S. If you need a small sized, very strong diff that is REALLY light. Subaru aluminum diffs work really well too. Most boneyards have a few.

This is real professional! Very good, studied construction. Perfect realization. No unnecesarry doings - all movements aim to final effect like in master chess play :). Last not least, he doesn't afraid to touch elements without terrible lateks gloves (awful plague among so called "masters"), much better feeling of material (what I know from myself experience). Congratulations and thanks for real pleasure to watching!

Seems this probably saved Rather B Welding some time in figuring out. Good job!

Looks beautiful, very impressive workmanship. I'm wondering how much power it could handle though..... I'm planning a trike for my next project, and this has the look I want. I don't know if it can handle 200+ hp and about 950-1000 lbs. I guess there is really only one way to know. I'll be trying in the spring, but probably with a GTO rear..... I hope it doesn't blow up.

Very nice work. Great project. Take care, EM.

You're dangerneering skills are top notch.

Most of you people talking crap about this dudes work couldn't even imagine to do all the work he just did. Great video

Great work, i was at the scrap yard one time and saw a ball differential, it was lawn tractor size, should have bought it.

Wow man your fab skills are on another level. Super impressive

This was a beautiful project. I do not know its intended use, but watch out for internal pressure from heat blowing out your seals. Most diffs have a pressure releasing vent for this reason. It lets the pressure out when it gets hot, and it prevent a vacuum when it is cooling.

Stupendous work and brilliantly filmed as always!

A youtube channel that doesn't use annoying background music during projects? SIGN ME UP! Subbed!

Outstanding mechanical engineering to say the least.

Majster świetna robota cóż za dzień filmy dodajesz mam nadzieję że to przez brak czasu

This is an open differential, I can appreciate all the work it took to make and engineer, but as soon as you have any loss of traction it’s going to be spinning one wheel.

Muy buen trabajo. Me encanta ver estos videos. Un genio. De alta precisión. Felicitaciones.

Make a well ("drill rig") that would get a lot of views...for all those DIY GUY... NICE WORK MAN ABOUT TIME WE GET A PROFESSIONAL DIY UKpostsR KEEP UP THE GOOD WORK..

This guys a perfectionist

Excellant idea isn't it ? Done this on an off road buggy 20 years ago. Stupid straight axle spurred me on to design the same thing.

Awesome job! 😉

Pretty impressive work, dude! 😃 Looking forward to see how you use it! Stay safe there with your family! 🖖😊

Awesome build. I want to build a 4wd go-cart with less than 10hp. Eventually, just because, I might try to turn it into an EV go-cart. Instead of trying to mount 2 motors, one and chain drive F & R differentials. 2 changes I would do on your build. 1, I suspect, was just not noticed during assembly. One pillar block has grease fitting facing the opposite way. It is easier to grease if both are in the same direction. The other is I would have put a bit more grease on the inside, not packed, but a bit more. All in all, it was a great build. Wish I had your lathe and bandsaw. 🤔

Travail tres bien soigné, bien expliqué bon continuation

Magnifica feina, m'ha ajudat molt per un projecte que tinc en ment, gràcies.

I admire your talent.

Awesome project and engineering, Sadly no-one mass produces these and should cause where i live steel alone might be close to $500 and then there is time + tooling required, where as its cheap to mount a driveshaft to the sprocket or to a jack shaft then run to a diff (which doesn't always work depending on setup). Def not bagging on your project i built designed and built a prototype but sadly one of my suppliers went to another supplier when they didn't have the specific parts in stock (after i told them that supplier had screwed me over and provided low quality parts that weren't up for the task), this ended up with my prototype in pieces and no way to recover the costs so it killed the project. Can also see why people like RPM stopped making them not due to demand but more supplier issues. Thanks for sharing, hopefully you inspire someone to build one for themselves.

Incredible! I'd really love to see a differential build for motorcycles that takes a motor that is putting out rotation perpendicular to the wheel so mini engines built for other applications could be used to make really unique designs using a motor meant for cars or airplanes but made small enough for bikes and motorcycles.

This guy with this skills reminds "Made in poland",great video,👍🏻

Pretty nice. What ever you are making will be pretty cool!

Nice work, must be a good quality 3 jaw in the lathe!

damn good job guy. I'm impressed!

Excelente trabalho!

An awesome chain drive combined with a terrible open diff,looks like a good work just the same.😉

Seriously Impressive Skills 😮😮😮

I am so damn amazed by your work. Very Nice!

Bad ass man... you got the fab skills no doubt!

You never disappoint. Can't wait to see what's next. God bless.

Very nice. I do see a tracked vehicle in the future. Just a kind word of caution. I would put some gear oil in the diff. you made. The grease will sling off the gears when at high speed and have no lubrication. Thanks for sharing.

Nice equipment and tools.

*My congratulations for this transmission I think it is a good design and it is made with experience.*

Czesc. Prosimy o częstsze filmy, widzowie czekają. Robisz dobrą robotę, jeden z lepszych kanałów na YT :)

Thank you for sharing, incredible job! I’ve been looking for ideas to build one for my VW bug that will be powered by a ninja 1100.

I have wanted to find a way to rig one of these up for years. My dream project in high school was to build a tracked go kart and a differential would be a necessity to drive it.

Great design concept, and well made. Would be a little worried by the noises!

Amazing work , you could do a production run for guys with bike powered buggies .

This is a good technique 👍!

Very very Beautyful and interesting work.

Ok. Gracias. Lo estaba necesitando para mi proyecto de gocart.

The thing that separates this differential drive from what most are typically used to seeing is that it's chain drive, not shaft. This eliminates the parts that create the most friction and heat, the hypoid gearset. Second, it also eliminates preloaded pinon and carrier bearings, which is the second most heat generating parts in a typical differential. Unless this differential is used in a manner opposite of a typical differential, minimal heat will be generated because spider gears are not designed for high speed rotation and by nature of design do not create much heat unless high speed rotational differential speed is stained between one side and the other for longer periods of time.

No w końcu wziął się do roboty 😝 Nie wiem co to za projekt ale zapowiada się ciekawie

Can’t wait to see what you build with it.

Marvellous engineering.

Incredible skills!

Nossa que talento Adimiro a inteligência de um torneiro mecânico

Merci beaucoup pour les efforts que vous faites pour nous montrer des belles vidéos comme ça 👍 vidéos intéressant et incroyable, bravo bon courage et bonne chance 👍 salutations à vous 🙏🙏🙏🙏🙋💐🏆

Sensacional, excelente, super profissional! Parabéns! Adailton - Brasil

Really nicely done, thanks for posting

Very fascinating to watch this being made. Super machine work.
