85 - Router Table, страница 7
Table Position Jig Whenever I tilt mv drill press table for angled drilling, I struggle to get the table squared up again using just my square. To help me do this with a lot more precision, I built the drill press table positioning jig shown in the photo at right. It's easy to build and accurate to use. The jig is simply a dial indicator attached to a plywood arm (see drawing at right). Hie arm is clamped to a set-up rod that can be chucked in the drill press. You can use any 5/i6"-dia. rod. (I used an old drill bit). To square the table, just slip the set-up rod in the chuck of your drill. Then raise the table until it just slightly depresses the extended indicator point. Next, rotate the chuck by hand (don't turn 011 the power) and watch for movement of the needle on the dial. The table is square when the reading on one side of the table is the same as that on the other side of the table. The jig takes only a few minutes to set up. And it's more accurate than using your square. Frank Penicka Mount Pearl, Nfld., Canada A R.B. Himes of Vienna, OH, uses a replacement pencil eraser for a protective cap on his air tools. The eraser fits over the air connection port to keep dirt and debris out. A C. Jeffrey Goldberg of Tuscon, Az, uses a plumber's Mack Lavatory Washer to keep his router wrenches from slipping off the collet during bit changes. He uses contact cement to attach the washers to both wrenches and then trims the washer away at the opening (see inset).
