Twenty Two Motors. Fifty gears. Eighty Two Hundred RPM. Hundreds of individual pieces, and one sheet of glossy paper cut into a disk. This isn’t a nightmare driven Rube Goldberg machine. Instead, it’s a Lego monstrosity created by [GazR] of [GazR’s Extreme Brick Machines!], and all of these parts are flying in formation for one Lego slicing purpose. In the video below the break, you can see what very well may be the worlds most powerful Lego and Paper table saw.
Starting out with a build that had a mere fourteen motors in a platform that looked quite a lot more like a table saw, [GazR] learned that having only fourteen motors turning a Lego based blade was not a good combination. In the next iteration, the same number of motors were used, but the gearing was increased to bring RPM up, and a Lego toy saw blade took care of cutting duties.
Seeing that higher speeds with thinner blades was a winning trend, [GazR] stepped it up to the aforementioned 8200 RPM twenty-two motored paper whirling Lego Death Machine. Yes, [GazR] cut Lego, carrots, carpet, and paper- all with circular sheet of paper.
Do Lego mechanisms turn your gears? You might enjoy this Legopunk Orrery from the Hackaday archives, too. Thanks to [Keith] for the great tip. Be sure to submit your own tips via the Hackaday Tips Line, or the #Submit-A-Tip channel in the Hackaday Discord server.
Not anywhere near me!
Good to see the LEGO being cut with this thing was already damaged before it was cut.
Eh. Lego is cheap these days. It’s just chunks of plastic.
I’d like to see someone cut a “cheap” piece from a Mr Gold minifig: https://imgur.com/F4vXK75
The whole minifig is $8000 complete. The torso wand head are very pricey by itself as they are unique to Mr Gold minifig.

Make the blade from sand paper and it will probably cut through anything.
That’s pretty much what they use to rescue car accident victims, and to slice up concrete. You can buy disks of the stuff at home depot and it really does cut through just about anything.
There’s cut, chip, scallop, swarf, shear and abrade.
None of the things here cut, all of them abrade.
which one is melt?
at least for the ABS parts that seems a significant factor.
Not having teeth would make this great for thin walled tube. Though thin, good and expensive diamond blades (not the fake Dremel ones) are perhaps better.
Is good to see material properties being made use of like this though.
This requires a test to see if paper can cut scissors.
