This was a nice pro level Yamaha alto that got dropped and dented in the top post assembly. I had to unsolder the octave pip (3rd Pic) to get to the area. In the 1st 2 pics you can see light leaking out where the tone holes are not level due to the damage. The 4th pic shows the finished work.
I don’t do a lot of drum repair, but I do change heads, replace hardware, and recover drum shells.
