The router bit me, now its time to reevaluate the safety of my shop
So I was setting up to rout a lock miter in a small maple box I was building last week, and while running a test piece through vertically on the fence, experienced a case of kick back, the board flew from my grasp, and sucked my hand into the bit. Ouch! It took off a nice chunk of my finger tip. Needless to say, the shop looks like a crime scene at the moment with the blood splatters, and I won't be making lock miters any time soon.
The cause? Could be a number of things I suppose...
A) router speed too slow
B) too small of a test piece
C) tired and working late
Unless the bit traps the work, like a dovetail, it should have been safe. A slower speed is not the best unless the diameter is larger. There is a recommended speed to diameter relationship in this chart: http://www.newwoodworker.com/ref/rtrbtspds.html
I suspect the test piece was too short, tipped and caused the kickback. I always run the longest scrap I can find, since a few minutes spent looking for one will save hours/days if anything goes wrong. No time was saved by "rushing" the operation. Slow down, be safer ..... albeit hindsight is 20/20.
The most often cause of shop accidents that I've heard...working late, tired, and in a rush.
As someone who had a crushed fingertip I "feel your pain" it still works fine, just looks weird.
