I have a dewalt circular saw, and was making a cut in a really dumb way and had a pretty significant kickback. The blade was pretty obviously bent so I replaced it, but now with the new blade on the blade rubs on the guard. The blade seems solid and and straight, no wobble or anything. The saw sounds right, other than the scraping on the guard. The guard does not appear to be bent (I don't know how the guard would get bent in a kickback anyways)...it's pretty solid and won't bend easily - I've tried to bend it away from the blade, unsuccessfully. It *seems* like maybe the whole shaft has shifted out a 1/4 inch or so...is that possible? Has anyone seen something like this before?
