    Gee that sounds like a high quality pump for pumping spam around an airplane. I am sure Boeing will jump right on that. Who knew it was lack of spam that caused two plane crashes.

    I wonder if worn out inserts are something you could use to braze into tools. What voltage are hand tools like drills and grinders? 400 volts seems high for corded tools.

    Why do 62.5 degree rhombic inserts exist? I can understand the 60 degree ones for threading but I am not aware of any use for 62.5 degrees. Is there some common flare or groove feature that is 62.5...
