āVibeā is a term that throwers use to describe the vibration of a poorly tuned or damaged yoyo. If you hold the spinning yoyo and run a finger against it, youāll feel it vibrate. If the yoyo doesnāt vibrate at all, it is termed "smooth.
Some yoyos arent smooth from the factorey i could be the machining, design, or the bearing when you throw down your yoyo let it sit at the bottom of the string and pay attention to where the string touches your throw finger and notice you can feel the vibrations on the string from the yoyo also vibe can be caused by a bad throw in which case just straighten it out and smoothen the throw with your finger this will show just the vibe from the yoyo and not your throw
The definition of Vibe changes weekly (opinion formed by reading this forum)
Lately it has been used to describe (among other things) the feel of a dry bearing and the result of a poor throw.
Generally however a lack of concentricity, roundness or balance in a yoyo creates a sensation players label a āvibeā (which sometimes if bad enough can be termed a āwobbleā).
If one thing were to be asked of you on this forum, it would be to proofread what youāve written before hitting Post.
As for the topic, what Ben said. I would also add that, in addition to extremely minute variations in the yoyo halves, the āstraightnessā of the axle also plays a part. If the axle is bent ever so slightly, that can induce vibe. Which is why a lot of axles are made out of titanium.
if you really want to know what causes vibe the two best people to Private Message would be ErnieK ( http://yoyoexpert.com/forums/index.php?action=profile;u=3049 )
or Dirty Birdy ( http://yoyoexpert.com/forums/index.php?action=profile;u=1690 aka db) who I believe isnāt very active here but is on the forums of One Drop and has a few posts there going in depth on the physics of yoyos including the effect of schmoove rings on suicides and smaller bearing-diameters effect on stability and sleep times.
I think there was also another person on YYN a long while back (I associate him with general yo, but Iām not sure if it was Mr. Kaiser or not.) who was talking about the several different ways the yoyo could vibe and was citing his experience with manufacturing motorcycle wheels.
