I have an x-convict and whenever i throw it, it always will vibrate. i’m not sure if that’s a big deal or not, but it kind of bothers me when i play with it. i use a KK bearing. i sanded down the metal rims on a lathe to make them smoother, but i don’t think that is what is causing the vibrations, because it was like that out of the box. is there any way to deal with this?
on a side note, since i sanded down the rims, they tend to tarnish (not sure if that’s the right word…) easily. i tried to metal polish it, and it works for a bit but the tarnish comes back really fast. is there anything i can do to the rims to stop this, such as coating it with something??
