Just to add a bit... most magnetic chucks have plates that slide up and down on one end and one side. You lightly grind the side plate so it is true to the travel, and place the work against it it make sure it is straight. You slide the end plate up enough to hold the work, but not stick above the surface to be machined. This serves as an absolute stop. If you need to, stack other objects up to the end plate and then place the work against them. Another thing to keep in mind is that thin parts do not hold well to begin with. The work is held best when it is as least as thick as the magnetic field, which is approximately the size of the gap between poles. So a chuck with finer poles spacing is far better for thin things.
