If you think you can't do it, then you shoudn't.
"In over your head" issues generally happen on older vintage saxes, but can also take place on newer ones as well. These include:
- A pivot screw that is frozen in the post
- A rod that is frozen
- A broken spring
- A broken key
- A bent rod
- A bent hinge tube
- A misaligned post
- A post with stripped threads
All of these are repairable with the right tools and know how, but can easily be made worse without.
I never understood why the springs have to be needle sharp at the loose end , I`m convinced it`s to ward off unauthorized sax repairing
