We Built A 1000RPM Katana Machine And It's Terrifying!

Sword Machine vs. Melon is going to be tough to beat for Slowie Of The Year.... Watching those blades flex was absolutely bonkers! Wonderful job, fellas!

[@beatles42ohgg94]

this is one of the reasons the katana was such a formidable weapon. did you see how they bent and wobbled like noodles? other lesser swords would either straight up break, or bend, and not bend back. that flexibility was what made them amazing. now, if only they attatched them at a slight angle for the slicing motion instead of chopping motion.

[@outandabout259]

@@beatles42ohgg94 actually you got that completely backwards. Katanas with their differential hardening have one hard but brittle edge and a soft spine that bends instead of springing back. Many spring steel swords from medieval Europe and other places, on the other hand, can bend pretty much into a C and will spring right back with no plastic deformation. Sure, a katana will not snap like a spring steel sword when bent more than it can handle, but the amount it can bend before plastic deformation is significantly smaller.

[@davepitts4479]

I have never been more concerned for your safety than I was today. When those katanas broke loose that was scary!

[@michaelbobic7135]

That was my thought exactly. I was just about to post that katanas are held in place by 1wooden pin when the blade flew out. So dangerous!

[@trif55]

Ballistic gel models of the boys! Also don't enlarge the holes in the katanas and put some wood or other reinforcement either side of them clamped with the same two (smaller) bolts through the holes so they absorb the flex with the blade rather than the tang with a massive hole in! Also where did that Katana blade go at 440kph?!? next Aus State?

[@Tuur75]

Yeah and most dangerous! One of those would easely pierce that container and anyone in it.

[@Kaishidow]

How is wasting food cool

[@brycereed4743]

When the blades reach the speed of "looks like its going in reverse" speed is insane to me.

[@howridiculous]

Yeh always crazy to see that hey

[@SureTadpoleYT]

This is actually due to the frame rate of the camera. When a blade is in the same spot in the circle every time the camera captures a frame, it will look like it's standing still. If it's slightly faster or slower it will look like it's going slow or backwards. This is the same reason it happens multiple times since all the swords look the same, you don't know how many swords you're seeing between frames and it can vary.

[@Saol.Alainn]

​@@SureTadpoleYT your eyes work the same way though, you'll see it on camera or off. Hub caps are a perfect example :)

[@outandabout259]

@@Saol.Alainn I don't remember ever seeing the backward spinning with my own eyes in natural light. It happens all the time with lights that flicker on and off though! As far as I know, eyes don't have a specific "refresh rate" where all receptors go on and off at the same time, there is a lot of overlap and at any given time some are on and some off, which results in a smooth blend and motion blur instead of sharp still images.

Katanas are actually incredibly weak sword that can chip and bend at everything if you tried to split someone down the middle you would break the sword and you can not cut bone with them well you half to hit joints so you don't make it impossible to use also you can and very easily with a long sword which are actually lighter than katanas split the katana in half they are not what they are cracked uped to be

If I was you guys, I would absolutely not be willing to do this without at least an inch thick wall of steel between me and the swords. I'd also probably lay down on the floor whenever it was active to lower the chance of me being impaled if a sword was flung directly in the direction of the wall. Edit: Also, I definitely would have made the same mistake with the dowels. While I have heard of that before, it would not have occurred to me.

[@rickglaze9980]

Couple of suggestions for spinny swords... 1. Build a funnel from some plywood and let the roundy items roll in a line out of a chute. 2. Connect a ramp wuth an angle to work in combo with gravity to cascade items into the rotation of the blades 3. Assistance might be needed from an agitator in case of less roundy things. Depending on the angle out of the funnel. This was a great viddy idea come true! Thank you, gentlemen!

[@procrastinatinggamer]

The flexing of the blades on that last shot is actually really cool because swords (not just katana but any sword) is supposed to have a bit of flex to it so that it doesn’t just snap as soon as it hits something hard like another sword, a shield, armour, bone, etc. That whole Newton’s Third Law thing applies to ancient weaponry as well.

A proper Katana is held together by a single bamboo pin, as they found out the hard way. The tsuba is pushed over the tang, against the habaki. The hilt material is then added, and the bamboo pin is inserted. They’re then wrapped and the handle construction is more or less complete.
