I have a 7 inch Jet bandsaw. I spent all day yesterday trying to adjust the blade to make it cut straight, I adjusted the bearing/rollers so they are snug against the bale but not jamming. i squared the blade perfect and it still cuts crooked. The blade moves away from the piece as it goes down I put a piece of 3x3x1/4 aluminum in it and the top cut to 2 3/4 the bottom stayed at 3 . thats how much angle its cutting. I even moved the blade to its as fas as it can go in. so that should make it cut toward the saw but nope still cuts away from it. Any oe have an idea how i can square it up ? moving the blade seems to make no difference.
