I just bought a cheap scroll saw while at lowes one day and actually really enjoy it so far, my only question is it seems like my blade is not 90 degrees to the saw (meaning it seems like all blades seem a bit bent). I don't know if it is something I've done or not, has anyone had this model and ran into this problem? I have bought replacement blades and they aren't lining up right either, so I would assume it's not the blades.
