A long jointed board serves as a great straightedge to help you level the extension tables. the saw table. But if yours is aligned to the blade, you may not want to do this. Instead, work through the access door below. You can temporarily remove the motor to get it out of the way. Use mineral spirits to clean away dirt and grease. To clean the gear teeth, I use a stiff-bristle toothbrush, continuously dipping it in mineral spirits. To expose the trunnion brackets for cleaning, crank the blade carriage all the way one direction, then the other. Use a thin penetrating oil, such as WD-40, to lubricate the arbor shaft, the arbor bracket pivot DIAL INDICATORS and the points where the hand-wheel shafts enter the cabinet walls. Don't use oil on the gears or trunnions, as it can collect sawdust. Instead, use a silicone-based lubricating spray or similar product. Graphite also works well. Avoid getting lubricant on the belts or pulleys. Improve Extension Tables and the Throat Plate Level the extension tables using a straightedge. First flush up the joints where the side extensions attach to the table. Then make sure the far ends of the extensions Adjust the blade angle stop by loosening its jam nut, then turning the screw in or out as necessary. After retightening the jam nut, make a test cut. are level with the main table. On a typical contractor saw, the extensions usually are bolted to the saw table and the fence rails. If necessary, just loosen the bolts, level the extension and retighten the bolts. The solid cast-iron extensions When it comes to checking the accuracy of your table saw, drill press, jointer or other machines, it's hard to beat a dial indicator. This simple tool consists of a spring-loaded plunger whose in-and-out movement is indicated by thousandths of an inch on the face of the dial. It can be used to determine the concentricity of shafts, flanges, blades and drill press chucks, as well as the height of jointer and planer knives. To use the tool, fix it in place next to the part you're measuring.A lug on the back allows for attachment to an adjustable boom arm on a magnetic base for convenient use on metal surfaces. Alternatively, you can screw through the lug hole into an appropriately sized piece of scrap wood that you have clamped in place. You don't need an expensive dial indicator to measure most equipment. You can get a 21/4"-diameter dial indicator with 1" of travel for $12.95 from Grizzly Industrial (800-523-4777 or grizzly.com - item #G1479).You should get a magnetic base, too, because of its convenience. Grizzly sells a good-quality combination kit that has both a dial indicator and nice magnetic base for just $19.95 (item #G9849). It's a small price to pay for accuracy. on cabinet saws typically are bolted only to the main table. If an extension droops at its outer edge, raise it the necessary amount by inserting a couple of shims at the underside of the joint. You can make your own shims from paper, plastic or even from aluminum cut from soda cans. If the outer edge of the table is too high, just insert the shims inside the joint near the top edge. If you use an outfeed table behind your saw, make sure it's set about V&" below the surface of the main table to prevent a workpiece from catching on it. Use your long straightedge to ensure that the entire surface of the outfeed table is parallel to, but below, the main table. I drove ^"-diameter lag screws into the bottoms of my outfeed table legs to allow perfect leveling all around. Adjust the height of your throat plate using its leveling screws.
