We calculated the launch speed of wood as follows:

"I really don't know
, but maybe we can calculate it:
A table saw blade at 4000 or so RPM with a 10" blade has a peripheral speed of 4000 x pi D or 125,600 in per min divided by 12 equals 10,466 ft per min. divided 5280 equals miles per min. times 60 equals
A 1" router bit turning at 20,000 rpm has a peripheral speed of 20,000 x pi D or (1.57) correction should be 3.14" or...... 31,400 in per min divided by 12 equals 2676.66 ft per min, divided by 5280 equals .4955 miles per min. times 60 equals (29.73 MPH) times 2 equals 59,46MPH
If this is far off, please forgive me.
I studied Art in school, so I can't read, write, spell or do math! I stayed in college so long they gave me a job teaching there! Thankfully, I got a real job at a big 3 car co. and retired early.
PS Good thing Howard Hughes is dead, he'd want to get a patent on Flying Wood!
The most dangerours tool in the shop is a mind that's not focused on the job at hand.
The shaper is a close second, which is tied with the jointer, which is in second place with the table saw!
