Hy guys,
I am a big fan of yo-yos and bladed weapons.
I have a project to make a tungsten alloy yo-yo weighing about 2.4 kilos.
I already have the possibility of having the materials, industrial 3D design and the industrial cutting.
The problem is that I have no idea what type of yo-yo to choose.
I would like a type of yoyo with a large volume of material so that I can increase the weight to the maximum.
The ideal size of the yoyo would be 65mm in diameter by 45mm in width. (I can’t do more)
I have never seen a tungsten yo-yo and I am very curious about the result I will get.
If anyone is willing to help me I would be very grateful.
PS : I am French and therefore I don’t really understand abbreviations.
I made two tungsten yoyos. Both are very very small but about 52 grams each. I 3d printed them with a 75% powdered tungsten 25%% petg plastic mix. It was expensive, the material costs about $230 for a kilogram worth. I made a fixed axle heart and an mr85 throw that uses Druid guts.
With the company I work for I can get a 65mm/45mm tungsten alloy block for 120€.
The Alloy would be ~18.96g/cm³
So the yoyo will be about 126cm³
With the cost of the 3D plans plus the cost of cutting it would cost me between €300 and €400.
And to think people try to make money selling drugs! W filament is where it’s at, appearantly.
In seriousness, as cool as tungsten is, how do you plan on throwing a 2,400g yoyo? The C3 BTH is considered to be mostly unplayable beyond throwing simple sleepers, and it’s only 220.6g. Unless you’re a rock climber, you’d probably need to put the slipknot around your proximal phalange (if not your wrist) to even throw it without injuring to your finger. If throwing super long sleepers with a yoyo made from a unique material is the goal, that’s cool. I just want to make sure you know the goal from the outset before getting into design.
All the other filaments this company makes are very reasonable cost wise so I assumed this material is rather costly and difficult to manufacture for 3d printing. But I dunno. It’s normally used to 3d print radiation shields and not yo-yos lol.
I would agree that I wouldn’t be throwing a 2.4 kg throw unless I was trying to break a world record or something. I have one that weighs about 100 grams and it’s painful to throw more than 2-3 times. Sounds like a way for doctors to discover the first case of yoyo elbow or something.
I’m just gonna add on what I said, if I listened to every time someone thought a yoyo idea was a terrible idea I would have made a lot less cool yo-yos lol. So don’t let our skepticism get you down. Live your dream! But maybe do some research in the cad and 3d modeling thread and learn how to run some simulations before you cut into a €400 brick of tungsten. Yo-yos usually require multiple iterations even with simulations and careful planning so also be prepared to have your first couple tries potentially end up in the scrap pile.
In fairness, it depends on the person throwing. Some people who have built up their grip strength & sinews can do one finger pull-ups, so throwing a 2.4kg yoyo isn’t out of the question. I sure wouldn’t want to play an hour long session with one though lol.
Might as well tie it to a deep sea rod while we’re at it. Did we just invent 6A?
If it’s gonna only be 2.4 kg… The purpose is obvious
It’s probably gonna be a looping yo-yo.
Interestingly, as I speak, I am also tasking myself to make an incredible yo-yo.
Amazingly, it happens to be 2.4 kg also
It’s gonna be an offstring Yo-yo.
The design I feel will be most appealing because the yo-yo will be Carved from the center of a wedding cake.
The challenge is simple. The freestyle routine is five minutes long as opposed to two or three. The rules for the competition are simple.
The freestyle starts slow because the yo is so heavy. As the yo-yo returns from the airborne position, you’re only allowed to catch it in your teeth. On each successful return, you eat a very large bite of the yo-yo. On succeeding returns the freestyle starts speeding up as the cake yo-yo gets lighter.
The last required trick is to heave the cake yo-yo very high in the air at an angle. As it reaches its arc across the stage, you do a double backflip with a half twist and land but first in a bathtub full of cold milk as you catch the cake yo yo-yo in your teeth on splash down. The judges award extra points if milk comes out of your nose on touchdown.
First place finisher gets a pair of vans and a 5 pound bag of tungsten gummy bears.
For this type of yoyo it should be used as a “boule des franc”
It is a cast iron ball weighing about 6 kilos attached to a rope which is itself attached to your arm below the shoulder.
Basically, to wind the yo-yo you will need to use the strength of your wrist and elbow.
W filament is where it’s at, appearantly.
