For bimetal (aluminum / steel) yo-yos, I’m curious exactly what percent of the overall yo-yo weight is in the rings?
I saw someone post a pic of a de-ringed Katana and it was cool!
the steel rings on my katana came loose after a bump, so i pried them off with my fingers and took the opportunity to play with the lightest functioning yoyo i’d ever played with
it works surprisingly well and is stable, i just had to be extra gentle with my trick movements
They said the weight of the Katana rings was 31.6g versus 66.3g total, meaning the aluminum cups are 34.7g. So the steel is 48% of the weight on the yo-yo, about half?
Anyone else done this experiment or know the weight of steel rings on other bimetals?
The outer ring has a weight of 18.5g, which is a very heavy weight, but the total weight of the ball is only 63.5g.
Let’s see
two outer rings = 18.5g × 2 = 37g
That means on the Refraction, the rings are 58% of the weight?
bearing = 2g
axle = 1g
that accounts for 39g of the 63.5g weight. By process of elimination the plastic shell plus the hub are 24.5g. I wish I could weigh the plastic shell halves, somehow… I’m also curious how much an aluminum hub weighs, exactly.
Found this very cool pic from @jeffreypang911, presumably titanium with SS rings
Let’s see…
10.92g, 19.60g … times two … 22g Ti body, 39.2g SS rings for a total weight of 61.2g not including bearing and axle, putting it at around 65g total. That means in the above picture, the rims are 64% of the weight?
Compare to:
Refraction, poly / steel 58%
Katana, 6061/ steel 48%
