You can cut these notches on your band saw but it's much easier to gang all the slats together and nibble away at the notches using your table saw. Grab one of the #1 slats and adhere a pattern. The hatched areas on the pattern indicate the size of notch you need to cut. Now gang all your slats together and clamp them tight. Make sure all your parts are square and flush. Attach a backing board to your miter gauge to minimize blowout. Carefully nibble away at the slats until the appropriate amount of material is removed. Now you need to cut the notches in the bottom rails. I used maple, but Baltic birch plywood The spacer shown at right allows you to continuously check the back rails' fit. It also keeps the back rails aligned while cutting future notches. might be a better choice. If your joints are tight, the maple rail's horizontal grain direction can cause the joint pieces to snap off during assembly. With plywood, grain direction isn't an issue. First, hold the oversized strips together, drill 3/l6" registration holes in the top corners and thread in two dowels. The dowels will hold the strips together and ensure alignment of the notch pairs. Enlarge the half-size rail elevation drawing and use it to lay out the notches. With the backing board still attached to your miter gauge, begin cutting away the notches on your strips. Be careful: Cut too big of a notch and you'll end up with some conversation-piece kindling. Cut too small of a notch and your bowl won't go together - especially after you add a finish. Don't rely solely on your pencil marks. Cut a /2"-wide x -long spacer from some of your leftover Baltic birch plywood and use that to continuously check the fit of your joint. Once all your notches are complete, cut the bottom rails to their final size. No Scrambling Required Once your bottom rails are complete, dry fit everything together. If you're happy with the fit, take the bowl apart, sand all your parts and break the edges. I like the natural look of wood (even Baltic birch plywood) so I sprayed my bowl's parts with three coats of lacquer. A paint job also would look nice. Do yourself a favor and cut two strips of K" scrap wood that fit in the notches on the slats to hold the slats upright while finishing - this cuts your Assembly simply requires a rubber mallet (be gentle).A little filing inside the notches helps tight joints, and a little glue helps loose ones. 92 Popular Woodworking November 2003 |
