I have a Rigid 12" compound miter and I am trying to cut down a 5" piece of cedar 4X4 into a 5" piece of 2.5 X 2.5". I am using this as corner blocks (to which I will attach short legs) for a platform bed. Of course the saw crosscuts the 4X4 perfectly, but when I cut the 5" piece on the grain (lengthwise to get a 2.5 X 2.5" block) it cuts at an angle. Its narrower on end away from me, and gets wider toward me, by about 1/2 to 1/4". I have recalibrated the fence/blade, and have tried to change the miter angle, but just cant seem to get a perfectly square 2.5 X 2.5 piece of 5" wood.
Help! I am so frustrated--maybe the saw cannot do this? Any advice would be appreciated (before I go out and buy a table saw).
