[pianotech] Front rail pin extraction

The tip of the bolt would not go into the slot that pushes the clamping

You may have used a larger vise grip plier.

Nope, no grinding required. Not sure I understand, though. I just
bought threaded rod of the same size as the adjusting screw/bolt that
I removed.
