Tool Test: Bench Grinders for WoodworkersSlow-speed grinders give a fresh edge quickly, without burning
Chris Gochnour usually review hand tools, but since bench grinders play such a vital role in keeping tools sharp, he was up for the challenge of evaluating a pool of 8-in., variable- or slow-speed machines under $200 to see how well they performed at shaping plane irons and bench chisels. Tool rests play a key role, so they were a big part of the equation. Machines from Craftsman, General International, Penn State Industries, Porter-Cable, and Woodcraft were tested.
