You could “re-draw” the plans on paper with full size or larger squares (you might have to make you own grid), then copying by hand the lines square by square. I have used this method by overlaying a picture of a object (of known dimensions) with a grid so I can re-draw the outline on a larger grid.

This is a common method. If I may elaborate a bit; I’ll make two assumptions. First, I assume that, when you say the magazine grid is 1/2”, it actually measures 1/2” as opposed to representing 1/2”. Then I’ll assume that the 1/2” magazine grid represents a 1” grid in reality. This means that the magazine grid is half size. So, in order to make the drawing actual size, draw a grid on paper with 1” squares. If it makes it easier and less confusing, number the squares the same on both grids. Now, as LesB said, where ever a line crosses the grid in the magazine, make it also cross the same grid line on your 1” grid. Once done, you will have the same drawing at full scale. Hope this helps.
