[Elecraft] Heat sink washer

[wa2dkg@juno.com]

<I've noticed the same thing. My final transistor doesn't want to lay
exactly
flush such that at disassembly, the heat sink raises just a tad and the
washer can very easily shift in re-assembly. It took me several trys in
reassembly before the washer reset properly and I could complete the
closeup. I've learned to ring it out with the ohm meter prior to final
tightning. I wonder if there is an adhesive one could tac the washer to
the
transistor heat sink so it can't shift?>
 
After the transistor and washer are assembled to each other and bolted
down, using the point of a dental pick or needle, put a tiny drop of
cyanoacrylic (Krazy [TM]) glue on it at the mating area of the washer and
the heat sink on the transistor...The glue is very thin and will wick
around the washer and bind it to the heat sink...Cyanoacrylic glue will
not cause a short once it is dry, but be careful not to apply too much or
it will wick into the threads and make later disassembly difficult...
