Just a word of caution to all of us out there who use powered tools (be it electric, pneumatic, etc.). I just got this e-mail message from my brother, who has at least 35 years experience in carpentry and home renovation. He is a stickler for safety and proper procedures.
Yesterday: 2.5" finish nail shot through (as in a missle) the work piece and flew 8" then went 1/2" into the palm of my left hand. I was dong everything right and still s**t happens. Anyway, removed nail and went back to work.
Fortunately, no serious damage was done - he is also an ER nurse, so he took care of the injury himself.
