I have an old Rockwell/Delta table saw and the fence doesn’t stay square to the blade when I am adjusting it. I have to eyeball it and take measurements to the blade in two spots every time I adjust the fence to make sure it is square. The fence is the very common tube style one found on many of the older saw. I think I just need to get it adjust but don’t really know how to do that. Anyone got any advice?
