"This video is one part instruction, one part entertainment

memories of youthful confidence and vigor, great adventure,
loved family members long departed, broken dreams and
gratitude for the blessings of my life."

Love the Essential Craftsman video's on YouTube. He shows all sorts of
great tips and tricks in carpentry.



I would like to point out that he makes a comment on the cutter tip
speed of the blades, around 10,000 Feet per minute. This speed is true
for most any thing cutting wood, including router bit blade tips. If
you are listening EC. A typical 10 TS circular saw blade spins at about
3,500 RPM, that times the diameter, 31.4" comes to 10,990 feet per
minute, around 120 mph. And the small diameter of many router bits have
to spin very fast 25,000 plus RPM for the optimum cuts. A 1.25"
diameter router bit spinning at 25,000 RPM is about 8,200 feet per minute.

Great video!
