A few months ago a broke a #4-40 tap in a heat sink. After a lot of cursing and futile attempts to get it out, I just left it for another day. I felt compelled a few days ago to go after it again. This time I came across an article on the use of alum powder to dissolve the ferrous metal (tap) from the aluminum without affecting the aluminum. Long story short, I got some potassium alum powder, set up a double boiler with a Pyrex container and six hours later and a little baby sitting, the tap was gone and I was able to save the threads and all. Kind of amazing. You can see the small bubbles coming from where the tap was. Note that I don't remember any chemistry, so I'm hoping this was safe. 20200227_181723000_iOS.MOV

Cool Story Bro: In the fall of 1990 I got my first CD player. A Pioneer 6 CD changer that used the removable magazines that were all the rage in the early 90s. I actually already owned a couple CDs at that point. The first "CD" I bought was the Led Zeppelin Boxed Set for $60 1990 dollars ($118 in today's dollars!) The second was one of a series of limited edition CD singles by Iron Maiden. In 1990 Maiden released their previous singles from the 70s and 80s (vinyl only, obviously) with exclusive B-Sides, 2 at a time on CD. They were expensive ($16 1990 dollars) but they had a bonus "Listen With Nicko" track at the end. On said track Maiden's drummer Nico McBrain would explain the history of the two single tracks as well as the B-sides on the CD. It turns out that Nico is absolutely hilarious and weaves an amazing yarn. One of the most infamous Maiden B-Sides in "Mission From 'Arry" which is not an audio track at all, but an extended argument between Maiden's bassist Steve Harris and Nico about extending a drum solo. The proceedings got fairly heated and were surreptitiously record by Bruce Dickinson. During the argument, Nico used the phrase "oh for fuck's sake, come on kids!" which has been in my vocabulary for 30 years now.

Full of Viagra.

I sometimes wonder how many good artists languish on YouTube with a couple hundred views. Stumbled on this while diving through music YouTube. What a phenomenal voice.
