Just got a freehand al in mint condition and unscrewed it to deal with a knot but when I put it back together it immediately starts vibing. I’ve unscrewed multiple other yo-yos before and never had this problem. Is there a way to fix this?
Yes - hand tighten and then adjust tiny amounts until the vibe is minimal (or gone)
I know this method is too late for you but just for future reference, whenever I ever unscrew a yo-yo, I place pieces of tape on each half and mark the tape with a marker to ensure exactly how the halves were screwed together. After I do the bearing maintenance and put it back together, I make sure the halves line up exactly as before. I’ve never had a yo-yo start vibrating from unscrewing since then. Could just be anecdotal, but it works for me
I’ll remember that for the future. Pretty sure I stripped the interior axle since I see a dent in it, although I’m not sure why it happened so quickly when I’ve opened up other yo-yos and they were fine.
Yea that can happen.
I try to remember they are meant to be used, and vibe to a point is inevitable.
did you swap around the axel and bearing?
You may have to tune the yoyo.
My Otter is very sensitive to the axle position. Can go from dead smooth to a periodic pulse just by unscrewing it.
I screw it together by alternating the sides I twist to keep the axle centered and it does the trick.
I figure that unscrewing a yo-yo can partially unseat both the bearing (rare) and the axle (common). Screwing it back together without addressing these potential issues may result in a state where it feels well tightened even though it isn’t.
The first time a yo-yo is unscrewed can also allow any metal shavings left over from machining or tapping to shift into a position where they will cause problems that didn’t previously exist.
Any time a yo-yo is unscrewed, debris that has collected in the bearing/bearing seat can migrate onto either part of the axle thread interface.
When re-assembling, I always fully seat the axle on one half. I choose whatever half is not retaining the bearing so I have enough space to fully seat the axle by hand (i.e. without a hex key). If necessary, I clear out any grit that is preventing the axle from threading in cleanly (in which case both halves need to be checked).
With the axle fully seated, I think that there is less chance of the entire assembly jamming in partially assembled state.
Just going to add that in general it’s best to keep the axle oriented in the same direction it came for smoothness.
