Time to deal with the disintegrated dial pointer. I flattened the red pointer with some heat and pressure. I couldn't salvage anything from the white plastic hub though.
So I dug through all my knobs and came up with this guy.
I cut down the shaft, drilled it larger and cut a slot.
Then, I filed off all those nubs, sanded it smooth and polished it up.
Here's a test fit. Not to shabby I think. The tuning shaft itself is off center. I think there are some adjustments screws for that.
