"Scratchy" feel on scroll wheel

[sWuRv]

It is a bit tricky to wrap words around it, but here goes- Ideally the wheel would scroll uniformly, where every little click feels and sounds the same. But one of the "clicks" in my wheel has sort of a scratchy feel to it, and produces an equally scratchy sound. The wheel performs correctly, so this is nothing more than an aesthetic pet peave. But it would really please me to get rid of this scratchiness. I'm not exactly sure how the wheel works, else I might have a better idea of what could be causing this. Can somebody give me a quick rundown on the physics behind this little bugger? I've tried blasting it with the good ol' canned air to no avail. Anyone???

spin the wheel extensively in both directions and press down at the scratchy points. it will eventually go away.

well...

it happened to me once... just try spinning the wheel both ways and blow on to it few times. I seriously wouldn't recommend using air under high pressure...



muaahhhhh... time to go to sleep..

bye ;)

Yeah I've tried that, continuously rolling the wheel and pushing it in while scrolling etc... All to no avail. I'm sure my kaiser is going to get disassembled sometime in the future, it's inevitable for any device of mine:p. I guess untill I have a good enough reason to do so, I'll have to live with this little annoyance.

You can always get a can of air..... no seriously i mean it! Air is fantastic.... well its good for breathing at least... :)
I use them for work all the time (i work on avionic & electronic systems on aircraft as a way to pay for my mobile phones). [no i DIDN'T work on the BA 777 that crashed....]


look at Maplin for example (http://www.maplin.co.uk/module.aspx?ModuleNo=-118&doy=21m1)

Absolutely NO guarantee that it'll work, and if its the same point on the wheel - its almost certainly wont! (try counting the "clicks" to see!)
However, they are fantastic for removing dust and other contaminants from sensitive components - also good for drying solvents from electrical contacts.

Should you get one, NEVER EVER - EVER use inverted in any way on a live system, even the "invertible" ones.... they still condense, throw out a wet draft, short the system and turn it into the most expensive blow you've ever had........... ;)
