What a name eh?
So recently I stumbled across a Canadian spin-top company called Foreverspin:
^ (there is there current Kickstarter project as well for anyone interested, I think these look flippin’ awesome.)
Being a huge Inception fan, I decided I had to have one, so I bought myself one.
Anyway, the cool thing about this company, and it’s main selling point, is that it machines the same design but in loads of different metals which all come out at different weights. For reference, here’s a rough guide to the weights of each top.
This has kind of sparked my interest in different materials for yoyos. What would new metals mean for new yoyos?
Aluminium/Titanium = Nuff said.
Steel = We had the ILYY St. Eel which I love, but that’s a pocket throw. I’d be interested to see what else could be done with steel. I know that it’s a heavy metal (at least 3 times the density of Aluminium), so no doubt making a full sized throw with it that didn’t weigh a fair amount would be an impressive feat, but I wonder exactly what could be done with it. The St Eel at least proved that machining it to a decent thin-ness is still possible whilst having sufficient strength.
Magnesium = We had the Duncan Freehand MG, and credit to Duncan for trying something cool. Still, we know that the Freehand is a more old-school design and whilst I’m sure that the Freehand MG plays great, I’m sure that there is more that could be done with the material.
Based on the graph above and how light Magnesium is, surely it’d be a great way of making lightweight full sized throws like the YYR Overdrive (but to a greater extent)? That would be very interesting indeed.
Brass/Nickel/Bronze/Copper/Cast Iron = I can’t think of any examples of a full yoyo being made out of any of these (though no doubt someone has at some point that I’m not aware of). I know that Sturm Panzer use brass weight rings on a number of their models but that’s all I’ve seen thus far. Due to the densities of these metals I’m sure any yoyo made with them would weigh a lot, but I wonder how much and which of these would take to machining the best. I’ll leave all of these to the professionals/more knowledgeable to take us through.
Tungsten = Sweet price tag Batman! The cost of Tungsten coupled with the difficulty of machining it and the huge density of it means that we won’t be seeing any “budget Tungsten’s” any time soon. Still, it’s strong and can be machined down to impressive tolerances, especially in it’s carbide form (I own a rather snazzy looking Tungsten Carbide drill bit and the cutting edge of it has been cut to a knife-blade level thickness. It’s heavy too, I like playing with it.).
I have a soft spot in my heart for Tungsten (there’s just something very cool about it being pretty much the heaviest metal that one can readily obtain without breaking the bank), and I would absolutely love to see what could be done with it.
Now lets discuss the other two from the recent Kickstarter:
Black Zirconium (on the right)= Man this stuff looks cool. I adore black yoyos, and I just want a yoyo made out of it. Unfortunately I don’t have the exact weight of that top though it has a density fairly close to that of the cast iron so I assume it’d be a similar weight.
Damascus Steel (on the left)= Now this has got to be one of the prettiest looking metals out there (second only to Timascus). Imagine a yoyo made out of this… on my word it would just be an absolute masterpiece. However from brief research it seems that it isn’t the easiest of metals to machine.
Finally… the grandaddy. There are no spin tops made out of this stuff but as far as I’m concerned it’s the best looking metal alloy out there:
I would sell my both my kidneys and my spleen for a yoyo made out of that.
It seems to be pretty well used within the knife making community and according to the makers has a machinability similar to Titanium (Jeffrey Pang I’m looking in your direction…)
Come on Luftverk, don’t let me down!
Sorry, I digress… I just like metal.
Now I’m not a Machinist (hard to believe, I know…), and I know next-to-nothing about the whole process besides watching the “Summit documentary” and bunch of episodes of “how it’s made”. So, I would love to hear from guys like The Machinist and Kyo who actually have experience with this as to what they think the possibilities as well as pros/cons would be for the various metals.
Machining difficulties, costs, strength-to-weight ratios… I just want this thread to be about all things metallic.
