I have had to fine tune all the power tools I own. New out of the box and freshly assembled in my shop. The only exception was my Excalibur Saw. I bought it from Ray at Seyco and it was perfect out of the box. You do have to tune all your equipment up after using it for a while, if nothing else to make sure square is square, 45* is 45* and so forth. Bolting down a scroll saw to a steady heavy base is a must. Makes an amazing difference in everything.
