@@GazRsExtremeBrickMachines Can you Help me with my Lego gearbox in my car my frames are bending and the gears slip. The car weights about 6 kg. I want it to get up a hill with 25° . My Gear Ratio is 1:15 and its very slow .I have more powerful motors , but it doesn't Help If the gears slip
Hey pig! The tower had its moments when the weights touched the ground! Unfortunately I deleted a vid by accident where the 6KG weight smashed into my floor. Somehow it didn’t go through my fake wooden floor :)
Awesome! Maybe you could put in a 1 way clutch so the flywheel won’t get stopped by the weight, and use the potential energy to launch a lighter weight like a plane?
That is amazing!! But honestly I’m more surprised how one motor could pick up that much weight! Unless you have it a little help lol. Amazing video as always man!! And glad you’re back to posting! And congrats on 110k subscribers!!
Haha cheers Easton! I had to give it help on the two bricks and 6kg of steel as the batteries were draining but when fresh it could manage the 2 bricks which really surprised me. Not the 6kg though! I’ve got quite a few builds going on so hopefully a few videos now! I still find it weird how I get the views I do, I’ve been lucky! That tug of war series helped :) I can’t believe people are still watching them
You need a faster reacting tachometer, there were a couple places where it looks like the speed got higher before the tach refreshed. Or a taller test rig would work.
@@10054 let's say the highest rpm is on the wheels for 0,2 seconds and your tachometer is reading the value every second. You will not get the highest value on your tachometer. If you now try to get the value from an slower shaft, the highest amount is still available for 0,2 seconds. Nothing changes, it's just slower.
But the screams if terror from the lego gears trying to stay alive really hurts me deep inside, you can't tell me the screaming of the gears and the plastic pieces of chipped gear flying everywhere hurts a lego lover
You’re not the only one, there was a slight mishap unfortunately I deleted the video. I should have added it at the end. Somehow my fake wooden floor survived lol
It probably doesn't make too much of a difference, but I still recommend fixing the tachometer in one location instead of holding it in your hand. Your hand isn't going to be as steady as a rigid frame for it.
@@GazRsExtremeBrickMachines You have Lego! Building a cradle for the one you have is always an option!! :D Even if it's just something you can hold it against, or rest it on while you hold the button down, it'll be far better!
I want to know how fast the wheel was spinning at the tip. My estimate is that if the radius of the 31,778rpm gear was 3cm, then the tip would be spinning at 3cm*2pi*31778/60/(100m/cm) = 100 meters per second, about 220mph. I also really want to see a follow-up to the video of attempts to get lego spinning at supersonic speed
Hey there nice thanks for that! I’ve been playing about with the supersonic attempt the last few weeks. It drains me a little charging the 60 batteries each time though lol. I’ve got over 700mph but the problem is I’ve used some nylon on an axle and visually there’s not much going on! I think the max speed I’ve hit is 730 so still a little short. Another issue is the nylon is so thin It doesn’t displace much air so there won’t be much to listen to either. I will keep trying though :)
hi Gaz! that looks fun, I can smell melted plastic from here!! another few seconds of freefall and the rate of cooling will be less than the rate of heat gain!? Great video as ever and as a gear head I totally get it and approve! now when you getting that RC crawler? 👍🍺😃😀🤓🤣🎇😎✅
Hey Carl sorry for the late reply I’m behind a little! The last few runs with the small pulley stunk, you know the smell lol. And yeah the heat ultimately slowed it down, one run even jammed stuck! I’ll see what Santa brings, I’d love a crawler! I’m going to Lanzarote in a few weeks and that place is rock crawler heaven! Youed love it🍺🍺😀
I have looked into this but the price kind of scared me(and I wasn’t sure if the cheaper stuff would work so well) it would be great to see a gear train heat up.
Does it need balancing across the axels? so there is equal tension on all the cables? maybe 4 axels with each pair connected round a pulley at the weight end
Hey it was fairly balanced but your suggestion would have helped, the fishing line/ nylon was quite stretchy so all the lines seemed to have a lot of tension. It was quite tricky to get right though, in fact a nightmare lol
I tried a similar thing using loads of motors connected to a propeller and had a plane moving using the prop only, unfortunately it ended up melting the shift into the bricks it went through after about a minute of continuous running, but it did move fairly quickly.
I noticed when the weight hits the ground the system reverses for a bit, is that from the kinetic energy storing in the axles and rebounding after the weight stops moving?
I didn’t want to block the view too much, also it was tough to film and get it all in shot from that angle. I need a tachometer which can sit there without me doing it. I have seen some on other channels but I can’t find them online. Grr
Fasterrrrrrr like 1000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 rpm
It's such a testament to the quality of Lego that you can do this with no damage to the pieces!
Yes indeed the quality still surprises me! That wheel is 30 years old I think!
There was some plastic bits coming off towards the end, but I didn't see any broken gears

An efficient transfer of mass is a beautiful thing.
It's like Russian roulette
I’m surprised the tower held up with all that, considering the wheel sounded like a jet engine.
Hey pig! The tower had its moments when the weights touched the ground! Unfortunately I deleted a vid by accident where the 6KG weight smashed into my floor. Somehow it didn’t go through my fake wooden floor :)
@@GazRsExtremeBrickMachines I guess you got lucky with that one!

Hey Alessio nice idea! I’ve got a few projects with flywheels coming up :)
That is amazing!! But honestly I’m more surprised how one motor could pick up that much weight! Unless you have it a little help lol. Amazing video as always man!! And glad you’re back to posting! And congrats on 110k subscribers!!

Yes definitely I’ve been looking for a better one this last week, it was quite tough getting a reading on this short run. :)
@@GazRsExtremeBrickMachines You could also just measure a slower-spinning shaft, and then calculate what the wheel is spinning
@@dragoncoder047 problem is still the same. The highest rpm is only available for a short moment, even if your rpm is lower than now.
@@Patar9 I'm confused, what if you calculate it precisely? You could still figure out the total rpm.
@@10054 let's say the highest rpm is on the wheels for 0,2 seconds and your tachometer is reading the value every second. You will not get the highest value on your tachometer. If you now try to get the value from an slower shaft, the highest amount is still available for 0,2 seconds. Nothing changes, it's just slower.
Seeing your lift baskets and their cargo is almost more impressive than the actual experiment.
Impressive, I felt for sure the structure wouldn't be able to handle the stress of the moving weights and pull itself apart. Lego really is tough!
Hey Lee yeah it’s crazy how strong it is, I did have a towel and a sponge to dampen the rebound, I just couldn’t get it all in shot.
Dam gravity do be spinnin
you should put a table or something at the end of these videos showing the rpms in relation to the gear ratios.
You’re right! That would have been better :)
Hydroelectricy uses gravity so if you plug it Into a electric dam would it count
Hey yes I’ve weirdly never thought of a dam like that :)
I love the sound of the gears
Hello, nice to see you
Hey cheers, you too :)
In some of the footage I can see what can only be assumed as bits of plastic from the gears as they are being shredded by the friction!
Each time I am hypnotized by your videos
Hey thankyou Michele, appreciate it :)
Amazing !
Hey thank you :)
But the screams if terror from the lego gears trying to stay alive really hurts me deep inside, you can't tell me the screaming of the gears and the plastic pieces of chipped gear flying everywhere hurts a lego lover
You should have smelled it after the last run! Awful!! :)
that started getting scary real fast man, was worried for you
Yeah the weights were a bit too much for the build lol :)
those are some scary speeds
Now that's an extreme brick!
Haha :)
Maybe do a weight-driven pendulum clock, and see how accurate you can make it
Hey that’s a good idea, I just saw something similar but powering a robotic man. It’s what my latest video was based off :)
@@GazRsExtremeBrickMachines This should get you started, since the escapement is the most important part: ua-cam.com/video/e-dXJJ-aJ60/v-deo.html
This is a really cool contraption!
Hey cheers I’m glad you liked it :)
thirteen pound weight goes in... Me: *sweats
You’re not the only one, there was a slight mishap unfortunately I deleted the video. I should have added it at the end. Somehow my fake wooden floor survived lol
Wow
Amazing video, i like how this machine is quite simple for what it does 👍
Hey hey thank you so much. If I’m honest this project did my head in trying to film it. I’m happy to break this one :)
Thats nice to see that you do what you love
Bro I’m sooo happy ur back. Still love the vids and the creativity! Keep going!👍
Hey thank you Nick it means a lot, I will :)
At 2:55 when the weight is dropped, it kinda sounds like a 5 cyl engine
Try using conservation of angular momentum to break the sound barrier
It probably doesn't make too much of a difference, but I still recommend fixing the tachometer in one location instead of holding it in your hand. Your hand isn't going to be as steady as a rigid frame for it.
Hey there you’re right! I’m looking for one which can sit in place, I’ve seen a few others use them but I can’t find them anywhere!
@@GazRsExtremeBrickMachines You have Lego! Building a cradle for the one you have is always an option!! :D

You should do one where you use lego to spin a car tire
F1 engines with 20k: Hold my beer
Interesting way of measuring rpm!
Hey Chris :)
Yeah using a device made for measuring rpm is totally an interesting way of measuring rpm.
hi Gaz! that looks fun, I can smell melted plastic from here!! another few seconds of freefall and the rate of cooling will be less than the rate of heat gain!?
Great video as ever and as a gear head I totally get it and approve! now when you getting that RC crawler? 👍🍺😃😀🤓🤣🎇😎✅

Imagine that pulley at 41,618 RPM as a Beyblade
So, its me, the guy who wont stop talking about robot combat, what is your plan for the lego combat robot? Will it have a unique method of locomotion?
Hey there I hope you’re ok! Do you mean robot fighting like robot wars? I’m planning to build a few and have a little series but it will take time :)
My guy at some point your gonna have to get out 2*4 and wd40. Improve the stability, reduce friction. I wanna see Lego go to space
rad (s per second) :)
gravity drill
Should use a thermal camera and see what gets hot/where most friction is.
I have looked into this but the price kind of scared me(and I wasn’t sure if the cheaper stuff would work so well) it would be great to see a gear train heat up.
Imagine if this is combined with BEC's winch lol. A 100lb weight on this machine would be incredible(ly dangerous lol)
Lol imagine the mess! And power!
I don't know why but at 1:30 it had a slightly sound of an i5 engine
The ultimate challenge would be to lift 200kg :) I think you would get a ton of views.
2:54 my man created volvo engine with lego
HOLY HELL. FOURTY-ONE THOUSAND RPMS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Very cool! Are you using the powered up app?
Hey thank you! I always use brick controller 2 so I can link my PS4 controller up. Makes it really easy to control a lot of functions :)
Looks like rat wheel. Good stuff.
Hey cheers :)
How did you support the weights? Crazy cool experiment!
Hey thanks Josiah! At the bottom I had a towel to dampen the rebound
Does it need balancing across the axels? so there is equal tension on all the cables? maybe 4 axels with each pair connected round a pulley at the weight end

Oh nice, yes the friction with propellers soon melts the beam, I had to limit one even when using oil.
Can't sleep so why not..
Haha we’ve all been there! Thanks for watching :)
i don't know but i'm going to find out!
I just woke up
the physics glitched
I noticed when the weight hits the ground the system reverses for a bit, is that from the kinetic energy storing in the axles and rebounding after the weight stops moving?
Hi yes that’s right, amazing how much energy was in the wheel, similar to my big flywheel test :) sorry for the late reply! Nice comment cheers
I think more torque and less power could do
Incredible: 700 spins for 1 second on LEGO "toy"... 👍👍
Hey cheers :) :)
All this contraptions, and no lego holder for the tachometer?
I do agree, my bad :)
car engines dont normally have a rpm that fast
I wonder how much rpm you could reach with some quality lubricant
I did use some but it needs a continuous supply when running :)
Try using fast spinning wheels to accelerate projectile.
laser tachometers are notoriously inaccurate
They’re great at a constant speed but it was tricky here.
Cool, now try whit no gravity
Why don't you measure the speed directly on the wheel?
I didn’t want to block the view too much, also it was tough to film and get it all in shot from that angle. I need a tachometer which can sit there without me doing it. I have seen some on other channels but I can’t find them online. Grr
How tall is that damn setup, those weights just kept falling
Hi I think it was 4 foot, 120 cm
hope you are wearing safety goggles
How did this not break any parts??
Good old Lego build quality! That white wheel rim will explode soon as its 30 years old!
How many watts can you generate with gravity
where can i get parts
where do you get the parts?
Hi I got most of mine from the Lego 42100 set off eBay. They’ve gone up in price now though, I bought quite a few :)
Brick link is great though!
Hello :)

Yo! Good evening :)
Hey man I’m still waiting for the video where the wheel gets too 1000kmh, you spoiled it in the comments 7 months ago, are you sti,l working on it???
