Bill Hylton is the author v/Ru uler Magic, frot,i Readers Digest. a Why do many woodworkers think they need a special jig to tigh:cn down the nut on a table saw? My woodworking teacher taught me tc do it easy as one, two, three: 1. Pla~e l he blade and shim on the motor. 2. Add the nut till it just touches the blade. 3. Turn on the saw. Since '.he nut is threaded on in reverse, the rapid initial torque of the turning motor is more than enough :o tighten the nut the proper amount. Then when you have to loosen the nut, it takes very little force lo unscrew it. No fuss, no muss, 110 bother ... and no special jigs needed. Ron Rosenthal DDS Fishersville, Virgin ia A You do not need a commercial device lo hold the table saw blade. We do tighten the arbor nut more than tlx.4 necessary light snug fit Still, either the blade or the arbor shaft has tc be held while the nut is loosened: otherwise the shaft and blade rotates. My usual low-tcch method is to use ci piece of wood at the front of the blade to stabilize it as I remove the ar bor nut. A zero-clearance throat plate made of wood or plastic works great. Your advice on bringing the nut and flange right up to the blade is important. If there is any space between the two, Ihe spinning arbor will torque the nrt on so tight that it will be difficult to remove tsiiifc any device! Tips: Look and see if the arbor toward the inside of the blade has flats on it. This is for using a second .vrench to hold the shaft while you loosen the nut. 1 he wrench either never came with the saw or may have been misplaced. I have also found that replacing the supplied arbor wrench with a better fitting longer one is much safer and easier. You gain leverage and your hands are a safer distance from the blade's teeth. — Kelly Mehler 0 Why are renter bits painted?
