[Elecraft] KPA100 Middle Side Screw Alteration

[Unifiedtx at aol.com]

I wonder if anyone has considered drilling out a hole in the middle side  
screw location on the KPA-100 big enough to force in an externally  splined 
insert that has a 4-40 internal thread.  The external spline would  make the insert 
grab the heat sink firmly so it would not turn with the  screw.  Does anyone 
know where such an insert could be found, and has  anyone done this?  Roy
