[R-390] Any advice for removing sheared machine screws...?

[Jordan Arndt]

Hi group,

I'm trying to figure out the best way to try and remove 2 of the 4 machine 
screws that hold the frequency readout "cover" on a 390A. They were sheared 
off at some point and there is not enough metal left to get any kind of grip 
with any kind of tool that I have.

I can see that one "stub" has a central divot from a drill bit, and the 
other is just a mangled down to where it exits the front panel.

I will likely try to cut a slot in what's left of the metal with my Dremel 
tool, and see if I can get enough grip with a small screwdriver to unscrew 
the remnants, but I have my doubts because I expect they were badly 
overtorqued and likely held tight in the threads...
I have to pull the front panel anyway, so I'll get a look at things from the 
rear of the front panel when I do that...

Any tips or pointers out there...??
