Whammy bars get over tightened every now and then, this unfortunatley snaps them inside the trem block, if your lucky you can drill and easy out the remnants, if your unlucky its permanently in there.

This is a left handed fender, replacement parts are hard to get and the remnants were broken off and stuck permanently, this walk through is how I restore the threads.

Time to repair approx 1 hr
Whenever drilling a broken screw, I will use a drill guide, simple piece of brass.
Fitted
We drill a 3mm starter hole, through the broken screw.
Clean away
Using an aircraft styled easy out, we attempt to remove the broken piece.
Since it did not come out we need to modify the existing hole.

We start with thread gauges.
Checking the new trem bar, its a 10-32 thread.
My drawer of taps and dies.
Trem bar has the threaded section snapped off completley.

You can replace the trem, but at 200-400 dollars for a LH version, not a cheap option.
Thread remnants
Turned and sized to suit the hole in the tremelo.
This recoil pack, is a rescue kit for a 10-32 hole.
