Aluminium axles are made by Metal Technic Parts a.k.a. Dark Ice Designs. They also make the metal gears and beams that were used in the max torque test bench.

Stainless steel axles were originally sold by Brick Machine Shop on BrickLink (obsolete), later cncgear on EBay (obsolete), and now planned to be sold by Prototype Production.

My absolute FAVORITE part of this video is that as it progresses, we get failure data for parts that aren't even suppose to be tested because the tests keep DESTROYING normal lego parts.
-
We’re all carefully watching this video like we’re some executives at Lego, and we’re about to approve the new material for a special Lego set.
-
The explosive nature of LEGO, amazing

The steel insertion test is what happens if you forget to chamfer your edges after milling. It had edges at the end that were still sharp, and with a few seconds with a file or abrasive could probably be considerably improved.
-
Carbon fiber has much higher potential, but the fibers in this axle are just in the axial direction. If there were fibers going diagonally around the center axis, the torque would be much higher. But due to the shape of these axles it might not be practically possible. If you could somehow do a pull test, the carbon fiber axle might be stronger than the steel one. But for torque, the carbon fiber axle is probably not much stronger than the resin used to reinforce the fibers.

Well, now this guy has metal beams, metal gears, metal axles and metal connectors. Should we expect a full-metal lego set?
-
Four billionaires cried out in terror and were suddenly silenced as the carbon fiber started to crackle.
-
3:08 I am now convinced that this is how drill bits are made and cannot be persuaded otherwise.
-
Not sure how feasible this would be, but would be cool to see this test done with different plastics (mostly thinking about Delrin) and maybe even different metals (like Titanium or something)
-
Pretty sure the Lego axles had better tolerances, hence the lower friction in the two tests
-
That twisted steel axle looks seriously cool, and it probably still works well, I'd love to see it return in a future build, just wherever you can fit it :)
-
Who else wanted to see a titanium rod 🧞♂️

3:35 This is the best lego destructive pop I've ever seen so far...

3:12 The motor- "Time to put on my hollow mask"
-
I feel like in the friction test, you should have accounted for the mass of the axles themselves, the steel axle isn't necessarily doing worse because it has more friction, it might be because it's just heavier than the other parts. Great video!
-
Would have been cool to see the amount of torque each could handle before permanent deformation. Feel like that would be more applicable for actual usage in most cases. Edit: nvm, those values are listed in the graph at 11:16

This is like Project Farm for Lego, continue this series please.

When using non-POM axles in general it is advised to use some lubricant. That is the biggest other difference between standard Lego axles and the other materials: POM is self-lubricating.
