HUGE fan of your series here! High-tech design, low-tech tools, low-cost parts!!! The essence of fun DIY garage builds!

One day a company will hire a brilliant young engineer who will propel the company to greatness ,and i will say “ yeah I remember him I watched his KZfaq channel “ I have been working in my garage for 45 years and I’m now 61 years old and still not as good as you . Well done young man I look forward to more videos

yo I have got to see a video on that lathe.... need that in my life

Excellent work my friend ! Do not forget to install the grease zurk fittings on your pillow-block bearings and grease them regularly for long life since your live axle is "sacrificial"

You are quite skilled! Love how you show a person doesn't have to have the Shop full of expensive tools. Just capable Tools in capable hands. Keep designing and building. I started with carts when I was young. Then progress to cars and 4 x 4's and finally ultralights and airplanes. The thrill of Designing and Building never grows old. And The Only Thrill that matches it, is when you use it for the first time.

Epic work mate. It’s so refreshing seeing and listening to a bloke just build something. Not like watching 90% of American build videos where they go on and on and on! Good stuff!

Waiting for the plans... Make them available soon...

Damn’ I have a lathe and many tools to do this project but THIS dude did it with just a few tools! Respect my Friend! 💪

Looks like it's coming along nicely! Really looking forward to trying this myself.

Man that is amazing. You are one smart individual. I truly enjoyed watching you work.

Gocarts have a solid axel as well. You can take them apart. Maybe you can look into it for ideas so stil can get to the bearings for maintenance. Like always a interesting episode!

Truely inspiring, keep up the incredible work

Cant wait for these plans!

Someone please buy this guy some tools!!!!!!! This young man is very talented.

A quick tip for the axles, when you go to the scrap yard pull off the hubs that go on the trans itself. You can modify them so you don't have to make your own custom ones. Plus if you ever break something you don't have to start from 0, just go pull another hub and use that.

You definitely deserved that cup of tea

This is awesome. I wish I had the skill and time to do this. Keep it up. This is some fantastic work!

So damn great to see you build new cool things with old stuff! soo inspiring! thanks for the great videos!!

Listen kid, I gotta say, you make some of my biggest childhood ambitions and dreams into a reality. It's a bit regretting that I didn't have the drive, know how and in all honesty, amazing talent that you clearly possess, but at least I am motivated and inspired to try it now as I turn 50 years old. So let me say a huge sincere and heartfelt thank you for the videos!!! I will definitely use your plans.

So simple but very effective great to see

Beautiful work, can't wait to see it drive. Hope you get lots of video racing around!

Very cool , I too, am waiting for the plans.

This is awesome! Cant wait for the next episode.

Kan je ook een video maken over hoe je die draaibank hebt gemaakt? Lijkt me heel interessant👍

Damn, you are one smart man. Skill on skills forsure.

Awsome work dude, i will buy your plans when you finished!

Just watched this what a talented fella I think u was about 4 minutes into the vid when I paused it to buy the plans 😀

Suggestion cut axle in middle put precision sleeve to join two halves together should have enough room between sprocket & brake disc to make sleeve long enough to be strong enough. That way each axle half could slide out allowing replacement of bearings & disc or sprocket.Use of quick change sprocket recommended if available.Awsome build I want a set of plans as soon as they are available! Would love to go tear up some dirt with you some time!

I just came across this young man's channel. Very clever and ingenious. I believe if you had a big shop full of equipment you'd be dangerous. Ha ha. I wish all the best for you. Your very creative. Don't ever give up.

Thank you for showing how you are testing and improving the plans before selling them. I have CBR forks too. Can you say how much suspension travel you are planning for the rear ? I would pay today for sure.

You're a young genius. Beautiful video, Bro. Greating from Italy. Max

Finally pt3

Great videos 👍.very informative.thank you

Great build so far, might i suggest in a few spots drilling half into the cv adapter and half into the driveshaft tapping and running a long grub screws to act similar to a keyway setup. The shaft could also be bored and tapped with a bolt and large washer to capture the grub screws so they cannot back out.

You are very talented. This series i stumbled into has been very informative. I am curious to know if this Crosskart design is legal as a cross kart that can be raced in varying competative environments. American Rally Association just recently allowed cross karts and side by sides in. The US CrossKarts can be quite expensive and this looks like a proper solution for me to be able to compete with one.

I’m glad that you said that you was going to weld up the joints

sangat menginspirasi bro... good👍 very nice...🙏 jangan lupa ngopi dulu...😁

Your axle shaft sleeves should have holes drilled in them so that you can do multiple plug welds onto the original axle shaft inside, this will greatly strengthen it

ide like a closer look at that diy lathe

Totally the best video on here well done keep up the good work ✌🏻🏴󠁧󠁢󠁥󠁮󠁧󠁿

You, sir, are a genius!

Great job on the crosskart buggy build 👍💯

Waiting for the next video so I can finish this build! Roll on next one!

Split the rear shaft in the middle and fit a keyed sleeve with through bolts into the shafts ;-)

You can mill the keyways with a drill press on both parts drill and tap end of shaft bolt center . Or just get serviceable zerked bearings and keep greased .. Is that 1" cold rolled shaft ?

You should check out the honda half shaft, i think it is present on the H22 motor, maybe other motors as well. Sits as an extention i think to have equal length drive shafts. Maybe that can work as rear center shaft in some way. Replaceable as well :p

Great videos, can not wait for the plans. Can your plans include a side by side (2 seater) version?

You got some real talent my friend great job on everything you make it all look so easy when its really not great job once again man awesome work and skills you got

Awesome build man ! Good job !

I thinking about doing a similar project. I want to make a quadricycle. A lightweight 4 wheel electric bicycle with two mid drive motors and a enclosed body. I like your design. However it would need to be very lightweight. Thanks for all the work, big help.

Differentials are pretty easy to make. You can make one from a Mazda miata 1.5 litre without specialized tools. Anyways you should put a keyway in that shaft. Maybe tap a hole in the end and use a big washer on it to hold it together.

Hola qué tal? Soy de argentina y estoy haciendo uno similar!! Quería preguntarte cuando miden las parrillas de suspensión traseras? Muchas gracias y excelente trabajo

Push those welds when you can. Cool build

very professional and definitely i like your work and i am also making cars that i like hoping to exchange experiences

Cant wait!

Wow, it's just perfect. Nice work. 💪👌

Fantastic build

One question. How do you plan on getting the brake disc and the sprocket on? It doesn't look like their center holes will go over the bearings or mounting blocks for the bearings.

Great video, thanks for sharing :)

Brilliant work bro love from Pakistan

you are very best !!! ❤️

nice work i like the way you do things

Nice I am at a point to were I'm trying to figuring out how to tension my chain I have a pretty heavy Spring tensioner under the chain it's still a little long so it seems like I need some downward force on the top of it to because it wants to skip over the drive sprocket when I let off the throttle. O Mazda miata axles are pretty lightweight with flanges

Awesome work my friend and I always look forward to seeing your videos!!! Can’t wait to get the plans for this build.

I think you are the best I am impressed I have that project in my mind but I did not have a clear video I buy you the plan

Don't forget to put the sprocket and brake disk on before you weld on the CV mounts! You'll have to cut the sprocket in half when it wears out!!

Good. Now I got an idea. Thanks

*Rất sáng chế đó. Trân trọng cảm ơn bạn nhiều nha. Chào bạn...*

very good metalwork skill

Genial bro, de nuevo mil gracias 🤙

Eres un genio!!

Awesome work!!

You should do two passes on welding the the rear axle up, great vids!!

this guy should get an oscar !!

Ben erg benieuwd naar provincie, en huidige werk/school status.

What is the type of pipe you are using and the size / gauge? Impressive set of skills for someone so young, awesome..... Are your plans available and how do I purchase?

Man! my crashed 2005 Kawasaki zx1000r ninja engine would be perfect for that racer.

Nice looking job mate

Quick question, how are you now going to get the brake disc and sprocket on the carriers after you’ve welded it all up?

Great work!!!

When you finish the geometry with the axles , I would recommend putting a rosette weld on each side on both of them , just to add a bit more strength to them , keep up the good work!!

Keep up the good work

Let me start by saying the skills you possess at your age you’ve got a VERY awarding future ahead of you! Seriously, all the money and tools in the world will never make the man, you’re either born with it, will learn it over a lifetime, or you should just stop and realize your talents are perhaps something not in the fabrication world and move on. Here you are with simplistic tools in a very small shop and your teaching me a 47 year old who would like to think he’s pretty damn good at fabricating (mostly the CAD element as I’m just old enough where I understand enough of it but never use it and end up doing it old school trial and error because that’s simply all there was when I was young) But the small stuff that you show like lining up your mounting plates square so many people would never do and fight it all the way to completion scratching off powder coating and still end up with a dog walking cart LOL.. You may not realize it but you’re teaching in many ways that you probably take for granted and don’t even know it! Great job! The only thing I wish was improved would be the addition of splined surfaces instead of welding. But with having to source out a shop willing to do a small job and not charge ludicrous money and taking forever because more important jobs making more money keep you on the back burner just isn’t in the budget on a cheap kart build so I totally get it.

Keerl fantastisch project👌🏻👌🏻👑👑

Man's tape measure has seen some stuff🤣 nothing wrong with that

Very well made ! Good that you print out those cutting patterns for the pipe, I just guess lol. How come front a arms are equal lengths? I made my top a arms shorter so you gain negative chamber as it compresses to help with cornering, like a trophy truck has. I have seen a lot of front suspension setups like yours on smaller buggies is it just for simplicity or does it function better?

Beau travail . Mais comment fera tu pour changer le disque de frein ? Au cas ou il y aurait de casse . Bonne continuation . franchement tu gère la cintreuse.

When and where can we buy the plans? I'm ready to start building!

cool work

Heb je die metale plaatjes soms bij staaltje vakwerk laten slijpen?

Will the references of the manufactured parts (like sprockets you took and suspension and motor) be available with the plans ?

Love the vids brother,I enjoy watching the content you have provided. My question is,at the point in which a project such as this one has reached its completion,the next step is testing.If all goes well with initial testing,step two would be the "shake down" I believe. Now,do you have a propper pilot capable for a sufficient "shake down"?I think one of the first skills necessary to posses by a skilled pilot is surely one with kahuna the size of ones fist.I appolagize for my slack jaw literature but my notes are not available for precise measurement numbers at this time.That said,I would like to forward you my credentials for the pilot position.The name to look for the email is"SENDIT". I specialize in all alloys ability to withstand unworldly conditions and subject weld strengths beyond any traditional standards.Obviously I no longer work in or with anything from China. Never the less,successful testing with my name behind it will free up many advenrtiserouse avenues in the field you possess the talent for. Honestly,I'm full of shit bro,I would like to see if we could make that thing fly though.lol Best wishes and bless you and your family in the coming years.

Instead of welding the center shaft, you could mount an end mill into the lathe chuck and the axle into the tool holder. Field expedient mill! I saw Rather B Welding do several keyways like this. That would allow for the axle to be end drilled and tapped for a washer and bolt for retainer. as for the endcaps, there is no problem with a rounded keyway. just use a drill.

How do you plan to get the sprocket on the driveshaft/ how do you plan to make sprocket swapping available?? The inside diameter of your sprocket doesn't look like it will clear the acceptor plates you've welded onto the driveshaft, or the square blue bearing housings you've trapped on the driveshaft.

Is this only good for a bottom mounted engine or can we use something like a Triumph 1050 speed triple which is cradle mounted? Love watching your videos!

I can’t wait for the plans! I’ll buy them in a heartbeat. All of us interested should make a forum so we can help each other in the process!

Nice work!!

in your part of the bearing and flange you could try scotch keying it 8 or a 10mm grub screw

Good job home made but very good
