[Elecraft] Overtighted Case Screw Removal?

[JWKIMBALL at aol.com]

I've found a little dab of valve grinding compound on the screwdriver tip  
works wonders working on aircraft parts.

I agree  on the (phillips) screwdriver tips.  They sneak up on you and you 
don't  realize that they are rounded 
off.  What I have done for another  alternate is to take a dremmel cut off 
disc, the thinnest one and carefully  cut a tiny 
groove across the head of the screw after first sticking down  two small 
strips of duct tape on both sides of the screw for  protection.
Just a tiny slot is all that is needed, then take a flat blade  screwdriver 
and try to back it out.  First I (gently) tap the screwdriver  head with 
a small hammer (gently) this helps loosen the interface between  the steel 
screw thread and the aluminum.  
If you have a new phillips  screwdriver you might try the (gentle) tap then 
turn approach first and see  what happens.
Good luck, I know it is frustrating !
Thumbs up on the  drop of oil on the screw threads too  !!!
