Mike,
you are a damn GENIUS! Thank you so much for the idea! I have the paste 
and I have a couple of old P-100 processor sinks. And I am just about to 
start fusing the coils individually, having recently witnessed Stefan 
flatbed his car only because of the stupid short in one of the coils. 
I'll do everything in one go.

Thx again. The timing of your post couldn't be more perfect.
