Alternative construction for Music Roll Hook

Alternative construction for Music Roll Hook
I was concerned about ripping the hook off the end of the music roll when the end of the roll was reached during rewinding, so I considered an alternative that would automatically release the hook when it reached the end of the rewind.

I made an extra take-up spool end while I was making the take-up spool assembly, and sanded a shallow flat onto the outside diameter. I then drilled a 0.125 inch diameter hole at about 10 degrees from vertical. I pressed in a 0.125 inch diameter brass rod so that it was within the outside diameter of the take-up spool. I fitted this hook assembly into the middle of the take-up spool so that the brass rod lined up with the center of the 5/8 inch diameter drilled into the middle of the take-up spool.

The brass rod hooks the end of the music roll and, when rewinding, releases the hook automatically.

See the figure attached for clarification.
