The right-hand table has shorter legs so that it can roll on swivel casters. A block of scrap leg material is glued into the inside corner at the bottom of each leg, providing a place to mount the wheels with #10 x 3A" panhead sheet-metal screws. A simple plywood box, the same height as the fence beam, can be placed on top of this rolling table to provide support for material to the right of the saw when needed. Leave Yourself an Opening The front upper rail of the saw table is reinforced with a second piece of wood that fits between the legs. I didn't bother with screws; I just glued it on, holding it to the existing frame's front with clamps while the glue dried. The plywood on the top of this unit isn't a solid piece; it is two 7"-wide strips going front to back at the right and left ends. The lower shelf on this unit may need to be slightly lower than the other units to ensure that the trash can fits. I used a Rubbermaid 32-gallon "Brute" that I purchased from the home center, but you'll need to adjust the opening size if you opt for a different container, or if you change the height of the saw table. On the Fence The fence assembly is a plywood box-beam. The extended front and back pieces of the beam are held to the top and bottom with strips of plywood. This beefs up the beam, and the width of the strips helps to level the surface to the surface of the saw table. In this entire project, the width of the strips is the only dimension that is important to hit exactly. This dimension will depend on the exact thickness of the plywood, and on the distance from the top of the saw's table to the base of the saw. Because 3A" plywood is notorious for being undersized, I took two scraps and placed them on top of each other, next to the base of the saw. To get a precise measurement I took my combination square and set the head on the saw table and slid the blade down until the end of the blade rested on the plywood scraps. After cutting a test strip, I put it on top of the scraps and used the blade of the square as a straightedge to check the width. If the strips are a bit too narrow, that won't cause any problems, as the fence beam can be shimmed up to match the saw table. One strip is attached to the long edge of each of the front and back pieces. I used 1V4"-long narrow crown staples and glue, but the strip can also be held in place with nails or screws. Be careful to keep the long edges of Gauge the distance. Stacking two pieces of plywood next to the saw table Double check. Checking the width of the strips with a straightedge will will give you a precise distance without measuring. help keep the fence beam at the same height as the saw table. Keep the edges flush. The thin plywood strip reinforces the front and back Quick and strong. The box beam construction keeps the fence assembly of the fence assembly, and locates the top and bottom correctly. straight, and the narrow strips of plywood make it easy to put together. popularwoodworking.com ■ 43 CIRCLE #152 ON FREE INFORMATION CARD. |
