metal rotor feels weird
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.
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.
Right, we always do something stupid, when some one tells you not to , often do it to test the result ......I oiled my Techno, a small drop of my high grade super oil on the spindle end.....
After that, very difficult to flick start , 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 :'(
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.
Hello pilch, dont push the center of the counter when you are putting it back to the shell, press it from the sides.
And about the changing direction of the powerball, i think that all about the technique, you just have to get used to it.
