I have a used DeWalt DW-715 compound miter saw that is giving me less than perfect cuts. When doing the fine tuning set up on it, everything appears to be perfectly aligned--zero degrees on the bevel, 90 degrees on the miter, checked with an accurate machinist's square. But when I use the saw, the resulting cut is bellied in the middle.
Please forgive me if I'm not using the right words here--I will try to explain. I make a cross cut on a jointed, perfectly straight board that is 4 inches wide by 1 inch thick. I throw a square on the board to check squareness across the width and each end is just a little less than 1/64 inch out of square--there is a "belly" along the length of the cut--it is arced instead of perfectly straight. Closest word I can think of to describe this is "snipe".
Is this a symptom of something wrong with the blade? The saw is fitted with a 32 tooth ATB DeWalt (the blade that comes stock with this saw). Or could it be something more serious like maybe arbor runout? Or something else I haven't thought of?
Or is this as good as can be expected from this saw? I used to have a 10 inch Makita SCMS that was dead nuts on accurate. Fitted with a thin kerf Freud blade it made glass smooth, perfectly straight, perfectly aligned cuts--was I spoiled by this and expecting too much from the DeWalt?
Any thoughts or suggestions would be greatly appreciated. Thanks!
