Just bought a TS55 yesterday. Having a little trouble setting it up. Need help. my problem is this, it seems to be cutting in a curve. it bows out in the middle of the cut and comes back to the original line at the end. When I make a cut and set a straight edge on the cut it seats 1/16 to 1/8 off of the ends of the cut. I have tried readjusting the cams several times. have tried them from very loose to very tight, no help. I am making sure the track is clean to make sure no sawdust is problem. Also, the splinter guard looks curved at the ends. Is it possible that my rail is bowed? what am I doing wrong? The saw does make a great splinter free cut in prefinished plywood.
