Hollow-grinding a chisel with a Dremel tool
Here's an extra video shot by Dan Erlewine himself! Link Van Cleave demonstrates how he grinds a chisel with a Dremel tool, and Dan whipped out his iPhone in time to capture it for us. It's the Dan-Cam! Check out this video where Link shows you how to keep your scrapers razor sharp.

Dan Erlewine: Here's a little tip I shot on my iPhone. It was leg flattening the back of the chisel a little extra with the dremel wheel.
Link Van Cleave: When I have a chisel that's hard to flatten the back, and it's a little bit rolled, it's hard to keep it flat on the stone to keep from rocking. So what I do is, I'll tape the bottom edge. Tape up the sides, and I'll go in with a Dremel and a wheel on a Dremel, and I'll come in here like this [Link holds the chisel at a 90 degree angle and moves the Dremel wheel back and forth horizonatally across the middle of the chisel in between the taped off areas], and we'll get back and forth. Then I'll turn it and go just inside what I just did [Link holds the chisel vertically and works the Dremel wheel left and right as he works down the middle of the chisel], and turn it and go just inside what I just did [Link holds the chisel horizontally and works the Dremel wheel left and right as he grinds from the top to the bottom of the chisell]. So the very center of this area has been hit three times with the wheel while the outside area's only been hit once. So it's going to create a hollow, and what that's going to do for me is give me a hollow in here so that this thing will lay flat on the stone and won't rock, and help me establish nice flat for flattening the back, and most of that grinding will go away.
I keep it safely away from the edge so that I remember. It'll go away by the time I sharpen back into that area. It just helps for the initial flattening and saves you a little bit of work.
