If you don't match the knob to that diameter, it can be off-center and cause a bad wobble.

If the shaft is an odd size, you may need to use shims to center the knob.

That's part of the intriguing nature of this design - there's no shaft on the top, not in the conventional sense. I'll have to take some additional pics when I get home, but the large silver "disc" you're seeing in the existing pic above is essentially what would be on top of the CP at the moment. It honestly almost works as a spinner knob as-is, but it would be nice to flesh it out a bit more with a larger/more standard feel. So unlike a knob with a small hole designed to fit a shaft, I'll need to figure a way to attach some sort of knob-like object to the existing metal spindle section shown. I hope that makes sense, if not, as I said I'll put up some more pics. Thanks!
PL1:
That makes sense.

Can you post measurements?

If possible, use calipers to ensure accuracy.

I may have my old spinner knob from my TT2 from GroovyGameGear.com.  If I find it you can have it.

No calipers in my toolbox sadly, though you just reminded me I want some. I'll do what I can with some accurate measuring, I think things will make more sense when I post additional pics later.

That would be really great, thank you! I'll get some pics/measurements on here asap so you don't waste your old spinner knob on me if it won't work for my setup. That way we make sure it goes to someone who can use it if I can't :-). Or I could always just re-gift it if it doesn't work out. I'm big on paying things forward.

Posting some more pics as requested. Here are a few of the process along the way using a second spindle and mouse encoder wheel I have. It's a snug fit, and just barely makes it through the test board. It will be close, but it will work on my CP + Lexan if I cut everything just right. The nice thing about using the existing mouse body is that the encoder wheel mount stabilizes the wheel as it exits the bottom of the CP. This prevents any wobble if you do it just right. I didn't even have to worry about aligning the encoder wheel with the sensor because the board and wheel are in the exact same spot they were before I gutted the mouse. Almost zero effort!

As for securing everything, as I said the test setup is just hot glue. Ideally I'll use a firmer solution on the finished product. Note the small screw holes on the bottom of the hard drive spindle (pic 2). Those can be used in a couple of ways: I could use tiny, longer screws through the CP into those to secure the spindle better and make it more removable or I can use small gauge solid copper wire coming out of each of the holes into small holes drilled into the CP, which will prevent the base of the spindle from turning. On the test setup, I used "spikes" like that with a little hot glue. It's never moved, even with my kids spinning away on the test setup like crazy people.

Note: Third pic is just to show how the encoder wheel goes into the spindle, this is before mounting.
