Hello. I've seen posts on this site that tell to adjust the front trunion by using the tilt wheel but when i do that I am unable to get the front trunion to move any closer to a 1/2" of the miter slot. All 6 bolts are loose. The tilt wheel lock is tight. Any ideas why I can't get the blad closer to the miter slot? I'm unable to use the saw for 45 degree cuts with the way it's adjusted now because the saw blade is too close to the other side of the miter slot.
