I have always been especially impressed by Technic MOCs, because of how complex they are. The side-dumping truck is mind-blowing!
I’m an underground engineer and I fell in love with this rebuild.
It look so good! It’s beautiful and it will make its little effect in the office of the box.
this lego tunnel boring machine is certainly not boring
Hi! Great build!! It's also so great that this is like a C model for the Lego Model. I really want to make it also cause it looks so fantastic and fun build. May I suggest something? If you have the whole model build an easy way to 'make' a manual is to just dissasemble it while recording (holding the pieces clear before the camera) and then just reverse the video! :) Thats how a lot of other builders on CZcams make tutorial/manuals. That way it doesn't take so much time and you always have a reference for yourself on how to make this model again. (If you don't already know it from memory after all these years that is! :D)
Great idea, thanks for the tip! I will try to document it in the future, as Morpheus says: "Time is always against us" :)
@@TheThirdModel if you make such a video and put it on CZcams or send it to me I would be willing to use Lego digital designer to actually make a instruction pdf for you to put on your website.
I wonder how far along are smartphone apps that will let you scan a model and automatically catalog most of the pieces.
@@JohnDlugosz That would be so cool. :D
I have made the instructions! Check out this video for more information: czcams.com/video/bMwpf6u0DCE/video.html
As someone who recently spent hours on a tunnel borrer in Minecraft recently it's very impressive to see a take in a lego format!
@Nitro Charge151 exactly, hours to make it waterproof
Damn, that's a beautiful build!
Thank you!
I think its pretty boring.
(Da dum tss)
@@UwUDaniUwU nice pun.
This is like "The Drill" from Avatar the last Airbender! Awesome Job!
My 4 years old is such a tunnel boring machine fan. He's been watching youtube videos about it when he was just 2 (on repeat!) . How I wish Lego can release one! My son will be surely be so amazed!
LEGO better pay you to use your third model idea
That's not boring at all, it's actually quite interesting
I wish I could give you 2 thumbs up. That is just amazing.
Top points on the gears and working/getting those values so close.
The only other thing I saw that would make it even better is to work on the gear box so it is autonomous. It extends, when it gets to the full extension distance, it flips the gear lever and makes it shrink.
Completely agree: I was thinking of how I might do this during the crawl past portion of the video. And I did it twice, 68 minutes each time, becuase I messed up the first one.
This needs to be a set on its own
Yeah for sure!
THIS NEEDS TO BE A SET
This has to be one of the greatest LEGO creations I’ve seen
The use of the worm gear really got me.🔥
This is extremely cool! I love how it looks and moves!
I have a lego crane set 42009 that transfers power linearly. It has 4 support legs that extend outward and then push down to lift the wheels off the ground and prevent it from rolling when the crane is in use. Power from the gearbox is transferred through a turntable into the body of the vehicle to power those legs. The power can be transferred to either a gear rack that extends the supports or through an axle that runs parallel to the rack to power the linear actuators that push the supports into the ground. The axle is long enough to extend across the width of the crane and is fixed to the end of the support, with a red 8 tooth gear that also slides along the axle easily being driven by the gearbox transferring power to the actuator.
The difference between your design and the lego set is that the gear stays in place while the axle slides through it, rather than the axle staying in place as the worm gear is pushed along the axle
Thanks! I didn't know about the 42009 before making this this video, but now I do thanks to you and others :)
I have studied these before for a class project and I can say that this is a very realistic machine in terms of look and functionality. You just gained a new subscriber.
What an ingenious creation! Absolutely beautiful! Nothing but respect!👍
I clicked on it expacting to see a nice tbm. After a while i understood that it‘s a (sort of) b model from the lego set and i was like daaamn that’s just amazing! I am really amazed.
I really want to see it chew through some soft dirt. Very cool build!
I might try this one day. When I first built it, I did get it to dig some Lego Pieces off of a wall. It worked surprisingly well, but a bit underwhelming. I didn't include a shot like that in this video because setting it up again did not seem worth it for the quality of the video I would get from it. However, I will keep thinking about a good material that it can try digging through.
@@TheThirdModel Maybe wet/packed sand?
@@Zombiehunter2_0 or playdoh or clay, something that wont break up into tiny grains that gum up the gears
Snow could work. It can self-support and be soft enough to be dug by plastic shovel. The TBM need to be cold to prevent the snow from sticking.
The mk2 mobile crane transfers power linearly to power the small actuators on the end of the outriggers they use the red 8 tooth gear which has the same frictionless property as the worm gear
Ah ha! I see that now, thanks for pointing that out. For others, check out step 100 of set 42009 from Lego: www.lego.com/cdn/product-assets/product.bi.core.pdf/6143639.pdf
Im about to comment the same! But worm gears are definitely a better option in terms of greater contact area and less torsional load to the axis
Actually the B-model used it to transfer power to the end of the extendable arm via a 32 studs long axle.
By the way:
It's a very cool model and it's even more inspiring!
@@jakobgschwind4722 Thanks, I'm glad you enjoyed it!
Agreed the B-model uses the worm gear to transfer power, but the conveyor belt that is being powered is not moving linearly - that is the one difference here.
the side dumping mecahnism on the dump truck is one of the coolest parts of the build! nice work
This machine is really impressive, it deserves millions of views and millions of likes, respectively.
the fire nation would be proud
This Build is absolutely genius. the worm gear mechanism just blew my mind! Please make the manual :)
I would love to see this actually tunnel through some dirt
This is like the avatar drill is so awesome
this is basically just the drill in that episode of avatar and I love it!
Great Idea and realization. I am looking forward for more videos.
Absolutely insane, be very proud!
Holy crap that's complicated. I love it!
Thanks for sharing! Love set 42055, your moc has to be one of the best alternative builds I’ve seen for it.
I was literally waiting years to see someone build a tbm out of Lego, well done man
The male urge to see it bore through something
Its a masterpiece! Well done!😃
Brilliant design!
The old yellow and red rescue helicopter (9396) has a really nice gear system, where you could switch it's function between 4 different functionalities on the helicopter.
Such an awesome build. Great video dude.
Excellent first video! I love alternate models, it’s one of the capabilities of Lego as a toy that the designers really capitalize on. I look forward to seeing what you do next!
This looks very cool!
AWESOME BUILD I LOVE IT!!! ♥️♥️
This is awesome. Especially as I am in Vienna, where the underground network gets an extension and such a thing will be operating near my place in the near future :-)
What a neat MOC! Especially doing it with only one set!
Awesome creation!
Looks like I have become an OG member as this is the first video ! I am a new subscriber (I think 234)
Such a brilliant idea!
wow, your skills are so impressive. magic
Wow thats a huge drilling machibe 😍
DUDE THIS MOC IS AMAZING!!!!!
I HOPE TO BE THIS GOOD SOME DAY
This is great stuff, I love it.
I presume that such a type of machine was used to build the tunnel lose to where I live, near the outfall of the Tunnel between the Kgatse Dam in Lesotho and the village of Clarens in South Africa.
Thanks!
It looks like a TBM was used. The Wikipedia article about the project does not say exactly that every tunnel was bored with a TBM, but that is most likely the case. There is a photo of the TBM used as part of the tunnelling infrastructure on Wiki: en.wikipedia.org/wiki/Lesotho_Highlands_Water_Project
Nice work
It looks and works amazing
vraiment très propre, félicitation !
very nicely done!
Impressive build.
Like how you explained in person and not just subtitles. Great job. New sub today 👍
Excellent!
It looks so good
Brilliant. Love it.
Love this video!
Это шедевр!!!)
Wow! this is really cool
Amazing!
Very impressive.
FWIW, the outriggers on the telescopic crane 42009 have sliding gears to allow for translation movement. They even have special parts so the gears don't grip the axles too hard.
Thanks! I didn't know about the 42009 before making this this video, but now I do :)
Thanks so much for this video!
keep up the build, king!
I’m not really in this hobby, but this is Genius.
This looks like bucketloads' of fun!
(pun intended)
either way, the build is 10/10 and looks real nice
Legendary!
9:41 It was hilarious to see you explaining this with a minifigure.
Thank you for noticing!!!
This is awesome! I’m proud to be the 490th sub. Cannot wait to see what you do next!
Impressive!!
That's really cool
This thing is used for boring, but it certainly isn't boring itself!
you'v just got a new subscriber epic build mate
This guy's gonna try to take over Ba Sing Se I can feel it.
I don't think at all that this is boring. 🤣🤣🤣
Sorry, had a long day. 😞
Awesome model. 👍👍👍
I hope you eventually got to the light at the end of the tunnel...
Thanks!
honestly i think its pretty interesting!
amazing video
Nice bro great job
So underrated I've subbed!
This model is seriously insane! I love evrey functionality and how it inches like an inch worm! Seriously incredible work!!! Also the only lego set I've ever seen with power being transferred linearly was in the 42009 mobile crane MK II, in the stability gear(arms on the side of the crane that slide out so it dosent top over( Idk the name lol)) anyways, I seriously love seeing linear power being transferred in models! Keep up the awesome work! I can't wait to watch more of your videos!
Thanks! I didn't know about the 42009 before making this this video, but now I do :)
Very cool:)
I would say "I wonder if this could actually bore a small hole in the dirt".
But then I remember that this is lego and full of things that dirt can gunk up.
Brilliant
Aye man why do you only have 1K subs this must have taken soooo long keep up the good work!
Your incredible and you deserve way more subscribers and views
If you put this up on Lego Ideas I'd definitely vote on this to be a set :)
I'll be back in 5 years for the manual
Great first video enjoyed just as much as some other Lego making CZcamsr ( Sariel's Bricks and Pets) and who have many more videos. Good job. Also really cool model.
I would love to see a manual or a video on to how to build it. But dont stress making it. Make it in your own pace, or dont do if you dont won't to make it. And congrats, you just got a new subscriber!
Thanks! At some point I will need to dissassemble the TBM and I do not want to 'lose' the model, so a manual is inevitable...
I have made the instructions! Check out this video for more information: czcams.com/video/bMwpf6u0DCE/video.html
We want to see it in work digging a real tunnel!!
this is so awesome wtf
I turned the Lego NASCAR into a mine runner, which is more or less a stripped down version of a regular car that you use to get around mines
This is incredible!!!!!! Does it work outside in the garden? You could install a train there using it.
Sorry pal but it cant work irl, cutter head doesnt have anything to remover dirt at the edges, also i doubt it has enough power for anything practical
@@gregtoja plus diet would get inside all those little technic holes
Fantastic design! I would love to build this model too since the B model doesn't excite me very much. Such a cool idea to make a tunnel boring machine from a single Technic set! I love the functions and looks of the model. Can't wait for instructions to build this. Good job :)
I have made the instructions! Check out this video for more information: czcams.com/video/bMwpf6u0DCE/video.html
Now you just need to make it actually dig tunnels, and it’d be perfect!
You should put this on lego ideas, I would love to build this.
Boring, huh? I think it's pretty interesting HAHAHAHAH
Omg this is unbeliveble
