metal rotor feels weird

[pilch o'death]

Hi

I got a 350Hz metal a few weeks ago and have had no problems until now.

I took it apart for a clean but when i put it back together the rotor somehow feels higher up than it was before. The support rings and such are in the correct positions, and all the parts are in good condition.

Has anyone else experienced this? It's really very annoying as it makes it harder to start, harder to get fast and it makes the rotor change direction VERY easily. The odd thing about that is it doesn't knock like it should, it changes direction so smoothly its hard to tell it has even changed! :(

Any suggestions would be greatly appreciated, this really screwed up my day :(

Don't really know but the only thing that could possibly do that is putting the blue running track back in 180 degrees out!
One face is flat and one face is flanged, the flanged face goes in first.
If it's not this sorry haven't a clue. ;)

Hi Pilch

After a while they Rotor bands tend to wear out quite quickly and no matter how hard you try that ball just won't spin any quicker:mad: and it tends to rotate around the axis, hence why it seems soooooo smooth. What you can do is check the washers and make sure the holes have not got any bigger and that the holes on the rotor band have not got any bigger. If they have then you need to change the washers and get a new white band. Also like the previous post mentioned check that the support band is in the right way.

Finally the 350hz is so much more powerful and because of this the wear and tear is so much more, it is worth checking, hope this helps, it did with me!!!!!

Hi

I definitely have all the parts in the correct way round, as the rotor would not spin as well as it does otherwise.

I have tried replacing all the parts with the spares that came with the metal, but that made it even worse! It just feels way more slippery (the rotor, not the outside) than it ever used to. Perhaps the cloth (my jumper) I used to wipe the debris from the inside was slightly greasy and has effectively lubricated the tracks.

It's feeling a tiiiny bit better than a few days ago, but still nowhere near as nice as it was before :(

The smallest amount of grease will make a BIG difference. Wash all parts (and hands, the natural oil on your skin will cause the rotor to slip) in detergent, rinse and dry thoroughly, reassemble and try. :rolleyes:

Right, we always do something stupid, when some one tells you not to:o , often do it to test the result:p ......I oiled my Techno, a small drop of my high grade super oil on the spindle end.....:eek:
After that, very difficult to flick start :mad: , and it is very difficult to detect the 'kick' ....difficult to start. Well good lesson to learn.

Oh dear, yep, shouldn't do that.

The first principle of the Powerball gyroscope is gyrosopic precession. That's what gets it revolving around the secondary axis, as you gyrate your wrist. Oil the little sucker and you'll be able to "precess" (if that's the word) rotor quite nicely.

BUT, the second principle of the rotor is friction. When you start the rotor and gyrate your wrist the rotor axle is travelling across the inner track faster than the axle is spinning, so it slips. But friction causes the axle to start to bite, and speed up. (Imagine sliding a shiny cylinder down a slope...it'll eventually start to roll...same principle with the Powerball rotor axle.) Once friciton takes over enough the axle will only be rolling on the inner track, and, as long as you maintain a firm grip, the gyroscopic force will cause your wrist to gyrate, thus forcing the precession, thus keeping the rotor spinning.

Oil = no friction = rotor will never speed up. Just give it a good clean and make sure it's dry and it'll be fine again.

nono, I didn't lubricate it on purpose (I'm not that stupid :P)

I took it apart today and gave the 2 halves a good wash and dry and now I can't even get the frickin counter back on. The counter didn't fit very well in the first place, kept making a knocking noise whenever i pushed it against the powerball.
It's still feeling weird though :(

And another thing, I was just using my plastic 250Hz a bit and i took it to about 12k and suddenly it started feeling weird as well, very similar to the way my metal feels, i.e. feels like the rotor is slipping about, feels "higher" than it should, and it changes direction randomly and smoothly without me doing anything. I'm tempted to send them back and get them replaced if I can't get them back to normal :(

GODDAMNIT POWERBALLS HATE ME :'(

[pilch o'death]

and to top it all off, I managed to mess up my metal counter trying to get it back in! now some of the digits look translucent.
oh, and I managed to delete my highscore as well.

Life sucks.

Hello pilch, dont push the center of the counter when you are putting it back to the shell, press it from the sides.:p

And about the changing direction of the powerball, i think that all about the technique, you just have to get used to it.:D :D

geez I've been powerballing for more than 2 months, I think I know how to do it, there's something wrong with the balls. Did you not read what i wrote? :S

[Adrena1in]

Funnily enough, what you describe is something that's happened to me in the past too, and I've been Powerballing for over 2 years. It's happened a few times with the Metal...does exactly what you says, and starts to slip and stop rotating, and change direction, even while I'm gripping it tight and performing what I think is the correct action. But a slight change of grip or something and it all starts to work okay again.

I've never been able to explain quite what causes it, but it must be me, because the balls are fine.

If you feel like there is a problem though, and the Powerballs are covered by the warranty, then feel free to email repairs@powerballs.com with details of the problem, and a link to this thread, and we'll see what we can do.

Well, with the plastic it happened out of the blue, as I was using it, so it's not a question of grip or anything. Similarly with the metal, I always use the same grip so that can be ruled out.

If they don't improve in the next week or so I will consider sending them back for replacement.

Thanks.

p.s. Sayex: sorry if that seemed rude, I'm not in a very good mood thanks to malfunctioning powerballs and such :)

Dont worry about it :p
By the way, that thing happend to me with the metal powerball, (now that Adrena1ine said something about it i recall it), When i first got my Metal model, it worked Perfactly, and when i changed the support band and washers, it started to that thing, but it didnt change direction.

Kind Regards ^_^:rolleyes:
