Since I bought my first table saw about 6 wees ago, I have managed to keep all my fingers firmly attached to my body. I did managed to get smacked by the off-cut that kicked back once leaving a bruise on my forearm.
This got me to wondering, “How fast does a table saw launch wood?”
Well, my saw says it runs at 5,000 rpm.
It uses a 10” blade.
So, the circumfrence is 31.4” (10×3.14)
So, if it was a wheel, it would be moving at 157,000 inches per minute. (31.4×5,000)
That’s 13,083.33 feet per minute. (157,000 / 12)
Or 785,000 feet per hour. (13,083.33×60)
Which comes out to 148.7 miles per hour. (13,083.33 / 5,280)
That’s the maximum theortical speed, not taking into account drag and other factors.
No wonder it left a mark. ;o)
