Square the table using this old machinists’ trick. Bend a piece of 1/4”. steel rod (available at home centers) into an S shape, as shown in the photo above. Mount it in the chuck and swing it by hand to each side of the table. Use a feeler gauge between the end of the rod and the tabletop to test the clearance at each end of the table. Adjust the table tilt until there’s 0.003” or less difference between the two sides. —George Vondriska
