It doesn't take much dust nestled in the corner between a radial-arm saw's fence and table to mess up an otherwise accurate cut. Eliminate the problem by creating a gap between the fence and table that lets dust drop out of the way.To bump out the table, select twelve 1/4" washers of equal thickness. Using a countersink, chamfer the inside of four of those washers to recess the screw heads. Remove the saw table, and install one stack of three washers at each end and the other two stacks about 12" or so in from those, steering clear of the blade's potential path. Make certain the washer stacks rest below the table's surface, and then reinstall the table.—Perry Johnson, Golden Valley, Minn.
