How on earth are these machined? On a CNC lathe? If so, do you machine the cup/spike/rims, then turn the yoyo around to cut the response bad and bearing recesses and drill and tap the axle hole? Or axle hole and recesses first then mount the threads on the lathe to cut the rest of it? If so, I’m surprised the threads are strong enough to hold up to the machining. I just don’t understand! Any insight is appreciated.
@theyoyoarchive It is highly welcome to publish my work in the yoyoarchive. But there are more measurements to do in the future. And I also wrote to Duncan for permissio to publish the Orbiter and the GTR. i will also scan one of the wors yoyos ever the Rev G when I will get it from @Zippy8

@Glad2bNico facturing is the secret of the manufacturer and this should not be discussed in this thread pls. open another one if you are intrested how yoyo are made
Awesome! Let me know when you get permission for the Duncans. Until then, I’ll get the others up soon!
Oof, sorry! My bad.
I’ve got two of your diagrams up so far:
Hi everybody,
long time ago since the last analysis is made, but I´m still waiting for answers from some manufacturers.
Meanwhile I get another piece of yoyo history, the Rev-G which I bought in this forum thanks for it!
I also have the drawings from the patent US6331132B1as a basis for my analysis, so the dimensions are public anyway.
The result is very astonishing for me because the data look way better than the yoyo plays (which is a pain
). Maybe there should be a factor added which also respect the absolute dimensions of the yoyo.Any suggestion?
