I was cutting a couple of grooves in a piece of pressure treated with a router. I was using a 1/4" bit set to about 1/2" and probably trying to take too big of cut. The bit felt like it was a little dull too, but that's not important.
What is important is the result. I smelled burning (like cutting tools do) and just thought it was the normal dull tool/too big of bite type of burning. However, the wood started to smoke! It kept on smoking after the cut finished!
That's right, I had started a fire with my router!
After filling a bucket with water, I shoveled the dust from the groove into the bucket. Some of the dust was red and obviously burning.
Everything's extinguished now, but this is one more reminder to be careful out there.
