I had a good laugh this evening. My 19yo son, who's never focused on the shop, asked what I was chuckling about after I read
's great response to my question about specific router bits. I explained briefly, and my son asked, "What's a router?"
Rather than walking a few rooms away to get my new Bosch to show him, I pointed to the chamfered edge of the kitchen counter and said, "See that beveled edge? A router did that." Then I explained it's a motor spinning a vertical shaft about 28k rpm, mounted in a flat base so you can hold it stable and run it along the edge, as the spinning bit cuts that edge.
"And it cuts other shapes too, anything you can buy/make a bit for..."
"See the rounded edge on that window sill... that was cut with a round over bit on a router."
"See the profile at the top of that baseboard?... that was cut with a router."
My son replied, "So a router is essentially the basis for modern civilization?"
