I think that you could increase the maximum RPM by a good bit by swapping all of the bevel-type gears to the standard spur gears, which have less transmission losses due to the smaller teeth that mesh better.
@@GazRsExtremeBrickMachines I would also recommend using a better lubricant than olive oil for the gears and axels, a teflon suspended pfpe grease would probably work phenomenally and minimize losses
Yup. I'd say something like boron nitride, which is the stuff used to lube moving parts in RC cars (one such compound is Tamiya Cera Grease); another good option would be PTFE, WD40 comes in one such formula.
I’ll experiment later! I’m wondering if it works will the tyre just sit there spinning on the spot until it realises it should be going forward… I can see quite delay until it gains traction!
The reason that the higher ratios don't make that much difference is that it takes an amount of energy to spin it at that speed, changing the ratio is like the length of a lever, yes theoretically youd achieve more speed, but you'd need more power to do it
I get what you are saying but usually a longer lever helps reduce effort/power needed to move a load. Having said that, if you increase the length of the lever from the fulcrum without increasing the thickness/strength of the lever you will run into problems. Or am i missing something?
@@carlsberg1668 that's more or less correct, it takes x power to move something, in this case spinning, so changing how the power gets there doesn't make a difference
Lol Kevin i did get nervous here when the tyres were on! Also you can see me with the saw at the end I’m clearly afraid and it’s only plastic!! And thank you very much 😀
‘Only plastic‘ That could be the worst last words someone would have ever said. If spinning fast enough, it‘s even possible to cut through hard plastic with paper. (There is a video in which someone cuts some scissors with a spinning piece of paper)
@@GazRsExtremeBrickMachines you definitely should be wearing a full face shield at minimum...but I'd really prefer a solid piece of plexi or something between me and something spinning at that rate. A small 4cm wheel spinning at 50,000rpm experiences something like 1100+ g's and has a surface speed of somewhere around 40km/h. Looking at a lego wheel chart, at 4cm they're about 15g...which works out to a apparent weight (based on the g force) of around 16 kilograms. So to put it in perspective, imagine getting hit with a 16kg weight traveling 40km/h and that's roughly the amount of energy contained in that wheel. That's only accounting for the weight and rotational energy of the wheel and not the rest of the gear train either. (Very rough math, probably a bit off given I'm assuming all the rotational energy is translated into linear energy but it's in the ballpark and makes a point)
lego pulley wheel with a 24mm rim spinning at 731.8 times a second works out to be 0.024*pi*731.8= 55.18m/s at the rim. Which is 198.6 km/h or 123.4 mph
You mention oiling the axles, but what about the gear teeth? One drop on each gear pair might net you a few more percentage in final output rotation speed. Obviously add the oil when it's at low RPM or it'll just get splattered everywhere ;)
Hey nice suggestion! I did do it btw you might be able to just see them shine, maybe. This difference was very noticeable aswell! I’m making a new rig now with 22 motors to see if it can pull the 1:375 ratio😀
I see the wheels can’t reach theoretical top speed, since the friction is overcoming the torque power of the engines, i recommend lowering the gear ratios to get more torque, since you don’t need those insane ratios with your current power Also, try to use bigger/smaller gears for the ratios, since those will be lead to less friction in numbers
Hi there nice comment! I was struggling for the bigger gears so I may need to change the setup and you’re right there’s less friction with them. I thought the second to last ratio was the optimum though with this power despite losing x % Any lower and it lost speed like the one before! I’m using more motors next time(22) so I reckon the second to last ratio will get nearer to its potential! The last ratio was very hard to turn😀
i would appreciate if you could make another video! 27K RPM on a lego sawmill is REALLY deadly, it could cut through anything like nothing (that excludes materials harder than wood)
One thing that's hard to notice unless you hand crank the wheel is how it can go from really resistive to smooth like butter as soon as the wheel goes from wobbling to loosely holding on
I made a gearbox that had like a 1:100 ratio or something. I ran it along the floor using hand to guide it. I got the same result with a smaller wheel, the rubber spun outwards from the centrifigul force (because it is very flexible). I also managed to launch a lego propeller with that gearbox (I guess lego really _can_ fly!)
@@odd_bobble9106 Mainly because I only had m motors which didn't draw enough power and either way your hand has so much more torque than any lego motor out there. I actually ended up twisting an axle (I was able to untwist it to some usable extent)!

Bloody hell! That’s just insane, you should flip it up side down and add some stabilizing wheels to see how fast it can go. Another great vid keep it up!!!👍😎👌
Hey Nick cheers! I just said to someone about that! A 3 or 5 wheeled car with one tyre in the middle! Gear it down until you have the right torque! Thanks as always 😀
The metal fibres are mainly needed so the tyre can contain the air pressure without ballooning up to a round shape that wouldn't have good ground contact. Against _unseating by centrifugal_ forces, the tyre bead would be enough.
What amazes me about these videos is that none of it is some or easy really it's all complex and straight from your head which is mad plus it's god damn Legos ! Top work I love it
kinda represents car manufacturers here they aren't limited by the engines and all that they can make, only by the wheels wheels on this thing just die when at comically high rpms
Considering that the radius is like 3.2 cm on that big wheel, the edge speed at 50k RPM would end up being like 160 m/s. I suspect this is at or above disentegration speed for the wheel.
As other people said, there is quite a significant safety issue here. Don't stay on the axis of rotation (that's were most of the shrapnel would fly if the wheel explodes)
Hi Daniel I buy the big sets second hand and sell the parts back I don’t want! The 42100 set has 7 motors and is worth 3 times more in parts which helps 😀
You should try and use graphite to lubricate the shafts of it. Alot less prone to heat changes plus the friction coefficient is far better then olive oil
I'm just laughing at home that 43k rpm are a lot in lego scale in rc cars I have motors that are rated for 100k rpm and in gold Smith equipment there are tools with 400k rpm that we use for really delicate work but still impressive that that's possible without bearings aftermarket lego batteries and only with olive oil because I have tried 30k rpm on lego axles and they melted instantly

Why are you using olive oil? I think axles are made of polyamide and bricks of ABS. There are much better oils you could use that would improve performance!
Hi there! Unless you’re using buwizz there’s no advantage really! And there’s buwizz 3 which can do powered up too. The powered up L motors are stronger than the power functions L motors and with the XL you can’t put them next to each other like this.

The problem with a hand crank would be the input would be from 1 power source and the load on the axle would be far too much I fear. Also the load wouldn’t be spread to the other gears as evenly😀
Hi Adam! It’s the difference gears spin at from the motor to the wheel. So a 1:15 ratio means for every time the motor spins once the wheel will turn 15 times! A 15:1 ratio would mean the motor spins 15 times and the wheel only 1 time so you would go slowly😀
I think that you could increase the maximum RPM by a good bit by swapping all of the bevel-type gears to the standard spur gears, which have less transmission losses due to the smaller teeth that mesh better.

Thank you thank you!! 😀😀
👍👍👍👍👍😃
lol @ the tachometer screen covered in olive oil drops. that's impressively fast!
Haha thank you and good spot! I later realised the whole room had a really fine covering in certain areas! 😂
Now we can finally make a Lego plane that flies!
You have balls of big Legos for sitting there with out anything spinning that as fast as an industrial Dremel.
Next time I’ll be more careful when I increase the power 😀
I’m not sure of the diameter, but if we take 1 inch at 43k rpm, the edge of the wheel goes at ~3km/s
I'm wondering something, do u know the power of 1 L motor? And do u think it's possible to use a generator with the lego motor?
Hey I don’t know btw but I need to find out! I will look in to it😀
Hmm this may be the most threatening lego
try hooking all the motors to a Buwizz hub for some real speed
That would be crazy but it would cost £1800 for 6 buwizz 3! Eek
@@GazRsExtremeBrickMachines you could put some higher-voltage batteries, like rechargeable lithium ones
I bought 6 of them but one was not working so I’ve still not put them to the test!
I will use 22 motors next time if not 😀
Super cool video 😎👍🏻
Hey there thank you very much for the comment 😀
Np bro😃
Ah yes, the amazing sound of a 5 cylinder using lego and speed
How much RPM would be needed untill the plastic wheel explodes?
I’m going with more power next time, so we could find out😀
Have you ever heard about whetstone blast? (Explosion of high speed turned whetstone?)
No I’ve not but I’ll have a search thank you 😀
Dude olive oil is sticky. You should use silicon spray for lubrication.
I will next time thankyou, it’s not bad though I was quite surprised how easy it made the gears turn 😀
I like how he sits right in front of it like it has no chance of breaking
I wasn’t right in front of it, to the side but next time they’ll be more safety involved 😀
Would be nice if you add a construction which can Shoot nerf arrows
That could be pretty lethal haha! My only issue is there’s quite a few been done recently. I will work on one though
Please explain what a ratio is, I'm very intrigued, also how does the gears work
Hi Adam! It’s the difference gears spin at from the motor to the wheel.
So a 1:15 ratio means for every time the motor spins once the wheel will turn 15 times!
A 15:1 ratio would mean the motor spins 15 times and the wheel only 1 time so you would go slowly😀
