Questions and Answers WINNER! Jim Goostree of Franklin, Kentucky, wins a Porter-Cable Compact Belt Sander (Model 371K). We toss all the Stumpers letters into a hat to select a winner. A Like putting an edge on the other cutting tools you have in your shop, burnishing a scraper is metalworking, not woodworking ... so don't feel bad if you need a couple of pointers. The goal of this task is to roll a small bit of metal from both outside edges of the scraper to create two sharp hooks (Note: this metal is malleable, not brittle). Step One: Prepare the narrow edge. If you are re-sharpening a scraper, use your burnisher to flatten the existing remnant of the hook edge. (The first time you sharpen a scraper, this is not necessary.) Simply lay the scraper Hat on a hardwood surface and slide the burnisher back and forth, Hat against the face of the scraper. Push down hard as you do this. (This action is called burnishing!) Step Two: Prepare a consistent rectilinear edge on the scraper blade. To roll the edge over, il needs to be square before you start. Often that means filing a clean "top" edge. You just need to remove a tiny bit of metal. Don't go crazy here. Step Three: Roll each hook. Clamp the prepared scraper between two pieces of wood or in a padded bench vise. The long edge of the scraper should stand proud about 3/8". I hold the burnisher with two hands and position il at about 20 to the face of the scraper. Then I slide the burnisher back and forth (yup, burnishing), pushing down hard on the edge. I alternate "left and right" using the same two-handed technique and a reciprocal angle, to form cutting hooks on both sides of the scraper. About five passes (max) for each hook edge is all it really takes. Interim Touehups: You don'l always need to file the edge clean and square. You can go back to step three and touch up your edge a couple of times before you go all the way back to step one. —Rob Johnstone What's This? Bob Corbett of Sturgeon Lake, Minnesota, received this tool from his wife's grandfather — and it's been a family mystery ever since. Know what it is? Send your answer to: Stumpers, c/o WJ, P.O.

Or email us at stumpers@ woodworkersjournal.com Not a butteris Stumpers Questions still linger on last mystery tool. it as "a wood carving tool for detail work," and Jim Goostree of Franklin, Kentucky, elaborated on il could be "two woodcarving tools in one. The first tool is a gouge. The handle can be reversed to the opposite side and rotated 180 degrees for the second tool, which is used for finer veining woodworking detail." Of course, Mike Linden of Cropwell, Alabama, thinks it's a "carpet slitter, used to cut straight edges for carpet from the roll before it was installed." —Joanna Wercli Takes Several participants in this month's Stumpers tool guessing game thought that the tool submitted by Allan Kirson looked like "a butteris, a farrier's tool for trimming the inside of the hoof and smoothing the bottom surface," as Arthur Matthews of Oklahoma Cily, Oklahoma, described it. Denny Kiehl of Joseph, Oregon, says he has "various farrier's butterises (blacksmith-made and factory-made) in my antique tool collection, including a factory-made one nearly identical to the one pictured." Farrier's butteris It's that "nearly" identical that gets us. You see, Stumpers has featured a butteris before (sec photo, above). This is a butteris. Allan's tool, we don't think is. What is il? Well, some reader guesses made a bit more sense. Ray I). Foster of Stafford, Texas, described 18 June 2009 Woodworker's Jou ma I |
