If this could be mass-produced as a kit and sold in a DIY assembly, literally take all of my money out of my bank account.
Love your work Matt.
😆 thanks 👍
~insert the fry meme~
Technically he could, at this scale, if no one have done this before, it's expensive but he could sell it a good price. Keep going dude
Try using two motors and split the drive shaft that should help the steering and you can control them to lock and add a drift mode
Yeah.. my plan is add second motor... And if it doesn't steer split the axle and make an electronic differential by monitoring the steering angle 👍
Need two brakes to properly do a split axle.
@@MattDenton would it be possible to add ackerman angle to the steering? Might help with the turning situation. Also, it might make sense to either print the tires in tpu or print molds and do a urethane casting.
Yeah I could do a urethane mold...
@@deanmcmullen5982 you can adjust the material properties of cast polyurethane to get an ideal hardness
Uhuh Ivan Miranda you say? That's super exciting 👍👍
Yeah 😆
Its terrifying to see such big lego bricks, messes with my brain
Yeah 😆
They're actually normal sized, Matt's just secretly tiny.
They're not even to full ratio.
Lego to Human scale is 3.5 Studs per meter. So a brick that's 7 studs long, blown up to proper scale, would be 2 meters long.
@@carumsarene I would love to see him do one that scale (Though if you do Matt don't use a 3d printer laser cut/cnc the faces of each brick in sheet material - it will be so much quicker and with proper solvent welds durable). Are you basing that estimation on Lego minifig though? Not saying it sounds wrong for Lego minifig scale just curious as lego's Human figures are none of them particularly 'scale' or consistent to each other - and surely the Lego Technic people would be the best reference for this build. I don't have one of those handy but I'd say its probably around 7 studs per meter scale from memory.
I've tripped over one!!
MATT you must be the first human on the planet that created a LEGO steady rest for a lathe.
I'm a huge fan of LEGO and found your channel via the Giant LEGO series. This project is just a new level of awesome and crazy.
Stunning work keep it up.
PS Would love to see a stud less build with some of the modern Double Bevel gears or even a mixed build of Technic bricks and stud less
Thank you. Appreciate the feedback 👍😊😊😊
You, James Bruton and Ivan Miranda are the triumvirate of insane 3d printed mechanical builds. When we're allowed out again I'd love to see a 3-way collab between you all, it would have to be some kind of... robot LEGO tank? Maybe the famous 8862 pneumatic JCB?
Yeah that would be great!!! I'll contact them ..
This is awesome. Now I want to build a truck and a camper like this. I've been saying for years that recycling plastic into giant Legos would make a sweet house...
Thanks 👍
I love it , when I was a kid in Brazil back in the 60's building blocks was one of my favorite things, we didn't have Lego "not that I remember", we had one called Hering-hasti and it was really nice, it had motors, a two speed gear box, battery holders, tiny light bulbs etc, but I also use to put 1/8" screws to keep it from falling apart, I also use springs from retractile pens for suspension and use to twist some of my father's paper clips to make control arms.... good times! ps: watching this video looks like you still can't "LE-it-GO" 😂
😆.. yeah it's a toy that got my engineering brain going and still entertains me today 👍
I was smiling through your whole video as I truly appreciate the engineering you have clearly applied to this and other models. I like the needle bearing washers, I'd never thought of adding them to the inner faces of the wheel. I'm sure them ninjaflex wheels expanded at full speed too. Keep enjoying.
The tyres do expands at full speed and spin on the rims :D
Man matt is smarter than everyone here on Earth
Hello Matt, it's such an amazing build, I think this project brought many new subscribers, didn't it? 😂
yes it did.. I hope it continues this way :D
It certainly brought me in
It's the Internet daddy with the new lego video! :3
This is what LEGO is about.
Just when I think my mind can't be blown anymore from RUclips... This guy turns up! I can do bits myself BUT this stuff is on another planet! Love the creativity and application 👌👌, Phenomenal keep it up, currently working my way through your other content, and subscribed 👍🏻
Oh thank you! I appreciate the feedback. pls share :D
Awesome as always! Looking forward to the next part!
Matt: *has 44k subs *
Also Matt: *replies to almost everyone's comments *
I do try.. I appreciate the feedback 👍
Like a boss
I know right?! I personally enjoy it. It means that the youtuber is one of the nicer ones.
This is so cool. I want to see more complex giant LEGO creations. Like technic cars. This is awesome and I’m jealous.
Check out my giant Lego bulldozer!!
Beyond the delightful build updates, I must say I really appreciate the effort you're putting into to masking or integrating any parts that are non Lego. It really shows a great devotion to the heart of the project. Looking forward to the next one!
Yeah that's been tricky.. but I have just machined a new motor mount plate which is going ot be hard to disguise... But may give a better idea of required power. Then I can rethink design
8:33 My OCD kicks in, then I notice that the front 4 wheels don't align either lol
Not a criticism by the way, I think this project is awesome :)
Thought the same thing, immediately seeing if anyone else noticed.
I'll line them up for ya both 😆
@@MattDenton Wheely good of you sir, thank you.
I get tyred when I see things like this, they tend to accelerate my OCD, but you my good man quickly changed gears which in turn allowed me to apply the brakes, stopping it from getting out of control.
Not many RUclipsrs offer differential treatment for people like myself but it allows us to tread more carfully to our destination, anyway, enough gassing, I am getting exhausted.
Btw, Judging by the quality of your work I am sure it is something you were well aware of already :)
P.S, I snuck a pun in there somewhere, I think I was pretty crafty but you may be able to spot it!
I watched this & automatically thought that I'd have the monopoly on tread pattern ocd; then I scrolled through the comments only to find that I'm not unique;.....wtf!!
Next somebody's gonna tell me that I'm not special either 😭
@@samuelbeckett4632 Nah, I saw it but I'd noticed Matt take care to get it right earlier so I was like "at some point he'll take a wheel off and fix this"
It would be super awesome to see you and ivan work on something crazy and massive together.
Yes it would 🤔
What a fabulous project, what fun. You are an inspiration. Eagerly looking forward to the next video.
Thanks
Truly amazing. As a former machinist, what you did with that shaft wasn't exactly orthodox, but it was ok, especially if you clamped down the lego blocks at the end.
Yeah it was a terrible idea as I say in the video :D but I was being impatient so wanted to give it a go. It was clamped down but the lathe was not happy doin it.. as you can imagine... that why I say don’t try this at home :D
Every kid needs a Doc, Rick or Matt in their family
Haha! I take that as a huge compliment! Live Rick and Doc 😁
Thanks for always explaining everything
You're welcome
Genuinely surprised we don't see stuff like this at legoland.
Very elehant solutions, love the tensioner supported by the rotating shaft.
The steering seems very sensitive!
Thanks .. yeah it's going to be hell to drive 😬
Hi, Matt,
What a great project. I look forward to part 3.
Surely you know it, but maybe some viewers do not.
The screws have to look beyond the stop nuts to prevent them from coming loose. At 6:30
Yes this is true... it was a temporary test 👍
Honestly, seeing the Technic pieces hold up that well makes me want to save up hundreds to 3D print the parts needed to build one of BIONICLE's 2009 vehicle sets.
Do it 👍
@@MattDenton I don't know if I'll be lucky to get close to the amount needed to do at least over 100 or so parts and acquire the resources to print parts of that scale (and mostly in multiples), but I'll certainly try, even if it takes years to do so.
Awesome!
Not sure if already mentioned but the belt tensioner "should" be made with the look of Lego and in grey. 😀😀
Absolutely love this!!! 😍😍
Thanks. You mean the out belt spacer! The grey bit? I could make a better version that covers the belt and looks like Lego 👍
@@MattDenton Not sure what to call it but you show it at 6:47. 🙂 It's just a small detail on an awesome build but still. 😀
Twin motors also solves the differential issue btw
Nice progress btw!
Can't wait to see it finished. I bet it will be better than you expected it to be. amazing job👍
Wow! What a project!
Thanks 🙏
Fabulous project Matt. The way Karts handle the lack of a diff is by setting up the steering geometry so when steering, one of the rear wheels is jacked off the ground (or at least, unloaded)
Yes I read this "jacking" I don't think I'll have any of that :D
I experienced this phenomenon personally when I was driving my sister's kart home one evening and the back wheel fell off. It was too dark to find it in the woods so I had to go the rest of the way on three wheels. It worked perfectly so long as I leaned forward and only turned left, but if I had to turn right the hub dropped and started dragging. Good times, that one was way too small for me too, and I clocked it at 55mph once. I miss that thing...
😆 who needs 4 wheels
cant wait for part 3 :)
Thanks
Matt you're nuts in the best way! Cheers.
Thanks 🤪
Great video, nice coverage and editing. Novel engineering solutions...that collet was a good idea. : ) Mahalo for sharing! : )
Thanks you. Appreciate the feedback 👍
So many super clever solutions!!!!!! Great work my friend!
Thank you 👍
I love everything about this
wow, i can wait to see it go
Just great!!!! I love it!!!!
Thanks 🙏
That's so beautiful!
Thanks
This is soooo coooooL!!!!
Thanks for all you do. Entertained and subscribed (and clicking thumbs up on every video !)
Ha! Thank you! pls share :D
You are a hero this is so cool
that LEGO go kart is amazing Matt. im so jealous of you being able to build one. also love your choice of music, sounds like the same band from the Ryan Gosling film Drive.
Thank you! and great film :)
Been looking forward to this!
Good! I've nearly done part 4.. but I think part 5 will be the fun one ...
Fantastic, Matt!
Thanks
You're my actual hero
Why thank you 👍
Who needs a Lamborghini? That's my dream car right there
👍👍
Amazing! Had me smiling most of the vid :)
God. appreciate the feedback.
This is going to be AWESOME! Can't wait for Part 3!
Thanks 🙏
Oh man, I can't wait to see the final product!
Thanks 🙏
I was certainly a new subscriber because of this, but I have no regrets. This whole channel is AMAZING. I'm really happy I found it. Doing great Matt!👍🏻😊
Thanks you. Appreciate it... Pls share 👍
@@MattDenton Of course! I've already got you 2 new subscribers as hooked as me!👍🏻
i was waiting for this video
Great stuff Matt. Thoroughly enjoying this one.
Oh and to improve steering perhaps try and chuck some weight over the front axle?
Yeah batteries are going up front.. and I'm shifting my weight forwards a bit.
That’s such a cool project! Nice Job!
Thank you 👍
Ivan to the rescue !! Love this guy !
Limit the speed? You ride a giant mechanical spider!! Full throttlee!! ;)
True 😆
This is just a really cool project! Can't wait to see how it turns out!
Thanks!
I love the idea and it is class
Watched this twise. with a huge grin my face.
Great 👍😆
This is an epic project, moving right along. Looking forward to the next episode. Thanks for sharing
👍👍👍😎😎😎 Cary
Thank you!
You should look up on youtube, how to make a lego pinball machine, and see if you can make it out of your 3d printed legos!
You do a great job in all your videos. Thanks keep up the work.
Thank you
Insanely awesome.... !!! WOW.
Thank you .. pls share 👍
Finally! I love Lego, I love go karts. This is perfect!
Thanks you! :D
I know it's way too late, but when I saw the single axle on the back end, I was thinking it is actually IMPOSSIBLE for any car(t) to turn a corner. Then I saw you wanted more power. My idea would be to cut the axle in half and giving each side a motor. That way the wheels can turn independently from each other, you have twice the power AND you only have to copy (and mirror) the existing pieces you already have made! Win win!
Already done it 👍👍👍
Y’ know he’s a worthy person to subscribe when he makes things I can’t even dream of and even a month afterwards he’s still replying
Oh thank you! Appreciated 👍
Wow! Just blooming Wow!! Such an awesome project. I’m so tempted being a Lego and 3D printing nerd. Nice one and thank you 🙏
Thank you 👍
After reading several comments about a split axle and separate motors, try this: Dis-connect the drive from the wheel on the opposite side of the motor. (let it spin freely)This will give you one-wheel drive, But will drastically improve your steering capability. This is how old-school go-carts work in the US.
Yeah I can give that a go... One wheel braking too 😆
@@MattDenton Yep, 1 wheel braking too. my first go-cart didn't even have brakes. I braked Flintstone style. I went thru a lot of shoes. When I eventually found a brake drum for my go-cart, I didn't have a brake rod (we didn't use cables) I actually used an extension cord tied around my foot and then attached to the brake drum. It worked for about 4-5 stops, then the wire broke. My return spring on my throttle was a fat rubber-band connected to one of the engine bolts. It worked for about 2 hours before it melted. hey, I was very young and didn't have much money. I used what I had available and it worked.. For the most part.
When I finally got all the correct parts for the go-cart, I took it for one last ride before I sold it at the Flea-market for $100. I never had another go-cart.. So SAD!!
😁... I'll buy lots of shoes 😂
It’s so coool!!
Thanks 🙏
I love this project !! Can't wait to see the next update
Thanks 🙏
Came here to suggest using the second motor idea as a faux differential to help steering. Good to see we all had similar ideas.
i love your excitement when you get to a point in the project when you can start testing.. looking forward to the next video dude!
Thanks. Appreciate the feedback 👍
awesome 👍
Loving this project, I would cut the KV on the motor to at least a 3rd of what it is now, try for a wider bell, shorter bell, more bottom end motor control and use a slightly larger drive gear. The torque difference would be huge and would cut the speed down nicely so that you can reintroduce it back in with more cells on the lipos in series.
Well it's a 149kv motor, there is only a 130 below this unless I go to a different design.
@@MattDenton I didn't consider it was already so low kv.
Maybe also 3D print a tpu helmet lol wow great work.
Will do :D
I love it!
Thanks
Great work dude love the vid
Thanks 🙏
im using this as inspiration for my lego motorised buggy :)
I love this.
Thanks 🙏
This is horrific and amazing all at the same time
Hi Matt, again an awesome episode, thanks! Maybe you can add an additional 1:2 reduction from the motor before the 1:4. It indeed looks terrifying, even just on screen, in real live it would make me run!
Yeah I need to do something to drop the speed and improve torque. trying to keep the gearbox simple though :)
@@MattDenton A twin motor setup will double torque, also.🤟🤣 What's wrong with speeeeeeed? 😉
You mad man, you're using the R/H stick as the throttle! lol
Yeah 😆.. this comes from driving droids on one stick.
Very nice. Good project
Thanks
How is it possible that not more people have subscribed to you?!?
This is awesome!
Thank you 👍 I don't know.. pls share 👍😁
@@MattDenton video is liked and everything 😁
Wow thats amazing! Got my sub!
Thanks 🙏
A collab with Ivan? Can't wait
Well he's helping me out more than a collab... But that would be fun 😁
@@MattDenton I will be shocked if the parts he'll print aren't RED.
Found first video. Subscribed. Been waiting for this yes.
Thank you! Pls share 👍
Excellent.
Thanks
You're insane!
Hello from Germany.😁
Thanks you! Hello back :D
Good work keep it up
if I was younger I would've loved to have something like this, really cool build!
Thanks 🙏
Liked, Shared, Subscribed. You are a genius!
Thank you. Appreciated 👍👍
variomatic belt drive will give you plenty of pull away toque, but hard to limit top speed or controll power pick-up with it since electric engines have no idle speed... personally im not a fan of variomatics, but they do work a charm.
i love it
oh god, need to make a 2-4x scale lego 12v train!
Amazing
Thanks 🙏
Fantastic video
Thanks
This is such a fun project to watch!
Gearing down the motor seems like a good move to get more torque, and also because the speed the wheels spin at the moment seems pretty nuts!
Yeah it need more torque less speed 😬
