Beyblades were a huge craze quite some years back. Children battled with spinning tops in small plastic arenas, or, if their local toy stores were poorly merchandised, in salad bowls and old pie dishes. The toys were safe enough, despite their destructive ethos, by virtue of being relatively small and lightweight. This “Beyblade” from [i did a thing] is anything but, however.
The build begins with a circular saw blade over 1 foot in diameter, replete with many angry cutting teeth that alone portend danger for any individual unlucky enough to cross its path. Saw blades tend to cut slowly and surely however, so to allow the illicit Bey to deal more traumatic blows, a pair of steel scraps are welded on to deliver striking blows as well. This has the added benefit of adding more mass to the outside of the ‘blade, increasing the energy stored as it spins.
With the terrifying contraption spun up to great RPM by a chainsaw reeling in string, it’s able to demolish cheap wood and bone with little resistance. Shrapnel is thrown in many directions as the spinner attacks various objects, from a melon to an old CRT TV. We’d love to see the concept taken further, with an even deadlier design spun up to even higher speeds, ideally with a different tip that creates a more aggressive motion across the floor.
As aggressive as this saw blade looks in action, not all are so scary. Even paper can do the job under the right conditions. Video after the break.
Well, that looks fun and entertaining. I’ll be on the lookout for semi-abandoned drug dealers’ houses in my neighborhood.
Perhaps welding a little nub off center on the end of the contact point would get it walking. But it would be great if there was some sort of guidance, maybe a stationary weight ( mounted on a bearing, kept station in the claw until release time). Though better yet, a remote control disk that can be steered (maybe a reaction wheel type guidance solution).
@irox: have a look at https://battlebots.com and see Ray Billings battlebot “Tumbstone” in action.
Gotta love Ray “If I’m spinning, I’m winning” Billings. That guy is legendary in combat robotics circles.
There’s a bunch of good videos of his combat robots to watch on YouTube. He also built Last Rites, The Great Pumpkin, and probably others (can’t remember and don’t feel like looking it up).
Very few robots come out of the battle box unscathed when going up against Tombstone or Last Rites, and often they come out in small pieces.
Remember that just because a house is abandoned or in poor condition doesn’t mean it’s now owned and you can be charged with trespassing or burglary, and the videos you post act as evidence.
*not owned
Daily Problems: “I´ve too many Legs!” *lol*
Was it just me or are the teeth on the blade running backwards? That would be an abrasion kind of cut, just grind out the bits you don’t want.
First thing I noticed ! And for those of you that made a comment about adding something to the disc, that would throw it out of balance and it would be totally unstable to a point it would jump all over and loose energy trying to stabilize itself, if at all possible. The speed this thing spins at would be SO radically wild. I wouldn’t want to be within a hundred yards of it. Back when I was in High school wood shop, the instructor told us about some guy on the wood lathe making a salad bowl which broke off the head plate at 3600 rpm. Later it was calculated that bowl shot across the shop floor, climbed up the wall and tore through insulation went a fair distance across the ceil before making its way back to the floor for another rip across the shop bouncing off machines and anything in its path causing some pretty hectic destruction. People in the shop area were jumping and scrambling to get out of the way. Don’t recall if anyone was injured, that topic didn’t progress in the discussion, we just listened to him go on about proper safety protocol such as shields on tools and staying out of the path in case something did go wrong. Any way that salad bowl was probably deserving of a land speed record, somewhere around 500 + mph at some point. Pieces were flying through the air also as it self destructed. This is just not safe no matter how I view it!
I’ll wait for the next video on “Reconstructive surgery for your feet in the privacy of your home”
This video could have been much shorter for what was achieved in these unsuccessful tests. I think it’s telling that the thumbnail for the video identifies that the saw blade will not be spun in the correct cutting direction of its teeth and that both spools are the same diameter, thereby missing out on a gearing ratio with a bigger diameter spool on the chainsaw that might have spun the disk much, much faster.
The goal is pretty clearly stated. It’s to make a large Beyblade, not to make a saw. Beyblades have spikes that stick out in order to hit other Beyblades.
The gearing suggestion is a pretty good one, you should suggest it in the comments section of the video.
Agreed with @Shannon and also just c’mon mate. IDAT videos are comedy first, engineering 47th or so.
Okay, now they need to make another one and a combat arena: Two will enter; one will leave.
Damn I miss the childhood beyblade days haha
