2024-07-01 (M) GrinderCompassMKIII REV11 spinner hub

The next phase of the new model was adding a hub. I made a hollow shaft from the bottom with a narrow collar at the top. The plan is to use a length of 1/8" (3.174mm) brass stock with sharpened ends. I will reduce the top portion's diameter further but leave a shoulder on the rest of the bar where the spinner will rest.

Before I continue, I want to prove this concept in the most uncomplicated design. If it spins well, I can change the connection between the hub and perimeter to allow some wiggling without making it too fragile. The wiggling will be crucial to the feedback mechanism, as with the current REVs.
