To help make part heights match, it is often times necessary to sand or file a part down to a size to mate well with a part cast at a different time. But what happens when you file that part? When sanding on a smooth surface, you will often hold the part by the sides with your fingers and move the part back and forth on the sand paper. This will help to keep the parts at 90 degrees and keep a relativly smooth surface. However, the pressure being applied by your fingers and the motion you put into sanding will also cause a part to become more rounded as the edges are sanded faster than the center. To help elimiate this rouding effect, you will want to hold the part by opposite corners. Then when sanding you keep your fingers in line with the direction of sanding. You will keep the part at a 90 degree angle relative to the edges of the part and will help to keep your fingers from applying uneven pressure to one side of the part over the opposite side, thus eliminating the rounding often experienced in smoothing parts down. This technique is best illustrated on the column base of the Roman Temple mold - if the two halves are not sanded properly, you will end up with a leaning column...
