How to Tap an Aluminum Heat Sink: Pete Juliano Shares Tribal Knowledge

This is a SolderSmoke Classic:  Pete Juliano N6QW coached me on how to tap (put screw threads)

a piece of aluminum.  This is an important homebrew skill that -- as I demonstrate -- is 

easy to screw up (no pun intended).  Thanks to Pete for sharing this tribal knowledge.
