Follow up on this: The chop saw has gotten worse as I've cut more steel with it. The wobble is getting more pronounced and the saw is now starting to have trouble cutting. Motor is bogging down more easily, like it's losing power. I've made less than a dozen cuts.
I've already boxed it up and it's going back.
Now I have to decide if I'll just go with a better chop saw, maybe from Dewalt, take a chance on the HF horizontal bandsaw, or really belly up to the bar and buy something like the Makita LC1230, which is a 12" carbide blade saw that everyone raves about. Expensive, but appears to deliver.
