I'm cutting dimensional lumber with a circular saw (a cheap 7.25" Ryobi I got at HD). I can't seem to ensure that the cut is vertical. Meaning, with the piece lying lengthwise while cutting, the cut should ideally be in a perfectly vertical plane, but turns out to be at least a few degrees off.
Is it typically hard to get this cut angle correct? I made sure that the bevel adjustment lever is set correctly, and the blade doesn't feel loose. I'm not sure whether it's because the saw is cheap or it's often hard to get right.
