   A machinists 123 block is a quick easy way.

   This approach will quite possibly get you in trouble since you will be getting an accumulated error as you work from one notch to the next.  The notches furthest away from the first notch will be off by random amounts making assembling the lattice difficult.

   The way to do this is to set up a long fence on your miter gauge. The fence should be a bit longer than the stock you will be notching.  Next, put a sturdy stop block on the fence at the appropriate distance from the blade for the first notch and cut all of the notches in all of the pieces at this setting. 

   Now move the stop block to position the piece for the second notch and cut all of those, and so on for all of the notches.  By proceeding in this manner, the notches will be in line with each other because they are always being measured from the end of the stock rather than from a previous notch.  Be sure that after making the notches you don't get some of the strips turned end for end before you start to assemble them into the lattice or the notches may not line up.

   For production work, like the grid you are making, you can group a number of strips into a rectangular bundle and notch them as a unit.  A good way to make up a group is to make the first notch in each piece, using the technique described above, and then tie the group together with a snug fitting cross strip in the first notch, the cross strip can be held in place with a screw into the first and last pieces of the group if necessary.
