A Bowl Gouge, as its name implies, is used primarily for hollowing bowls. Round-nose Scrapers are part of a family of turning tools that come in a variety of shapes and sizes. to 440-grit and apply the finish of your choice (see bottom photo, previous page). For this project, I needed a fast-drying satin finish. I applied wipe-on polyurethane with a paper towel and immediately wiped it off with the piece spinning. This created enough heat to quickly set the poly and bring out the nice satin finish I wanted. Next, finish shaping the outside of the box (see the Section View Drawing). Taper the bot- three-jawed spigot chuck, but this technique is cheaper. Use a set of calipers to find the widest measure across the lip of the box. Transfer this measurement to the bottom of the lid as shown in the top photo. Using your skew, make a cut, just inside the mark, 1/32" deep. Test-fit the box until it fits snugly into the 1/32" cut. Now, using your bowl gouge, hollow out most of the wood in the center of the lid. Use your skew to remove the wood on the inside edge of the lid, making sure you leave a clean, sharp edge to create a very snug fit with the bottom. It is better to make the lid too tight at first and then slowly go back and remove wood with a scraper. Transfer the diameter of the base's lip with a set of calipers. The fit at this point must be very tight so you can turn the two parts together. Use the lid blank as a ram chuck to reverse-turn the concave bottom of the base. Then size the lid to the base's exact diameter. It's a very slick technique! torn, working from the rim toward the face plate. The shape of the base is now complete except for reverse-turning the bottom, which you will do after you've started on the lid. But first we'll use the lid as a ram chuck. Turning the Lid Start off by turning the lid round, as you did with the box. I^eave the lid diameter 1/4" larger than the bottom, so the lid can serve as a ram chuck. A ram chuck is a piece of stock — in this case the lid of the project — created to hold by friction (ramming) an open vessel (in this case, the base of the project). You could use a |
