Oscar Model 1 Spinner question

Kremmit:

Yeah, it does look like he was using wheels pulled out of mice on those old spinners.  You could probably open up a junker mouse to see if it has a likely looking replacement inside.  Heck, I've probably got one of those sitting around from a mouse hack, if you want it.

Or, do what crsdawg suggested, and get a wheel from GGG.  I'd suggest buying the "Trackball Booster Kit" instead of those "Replacement Encoder Wheels".  Reason being, the "Replacement Wheels" only have 24 teeth on the wheel,  which is kind of low for a spinner, you can tell that the wheel that originally came on your spinner had more than that.  The wheels in the Booster Kit are higher resoluiton.

You will have to re-mount the optics, but it looks like all you'd have to do is attach a spacer to the existing bracket to mount them to, nothing too radical there.

Again, thanks for the suggestions.  I think I have a few old junker mice laying around here somewhere, so I'll crack 'em open and see if they use anything close to what I need.  I also have some old laser mice, but I'm guessing those don't use encoder wheels.

Ok, I've found an old mouse and encoder wheel that is pretty close in size...just a little bit smaller.  I guess I can just adjust the board and optics to make it work, but my question now is...how might I go about removing the encoder wheel from the metal roller rod without breaking it in the process?

Just thought I would ask those with experience dealing with small electronics and/or small mechanical parts...btw, here's a couple of bad pics to illustrate what I'm talking about...
