Well it certianly puts a big shank in the "lapped my heatsink and achieved a 4C improvement" BS. I seriously doubt there are very many who have gone to the extent of work outlined there. I had heard the term "pitch lapping" before, but had no idea pitch meant pitch as in tar like substance. I thought pitch refered to some angle approach or something...totally off...
I am very currious to know how the similar the techniques outlined by the links in this article are to N8's methods.
