I think you could also take the advanced step of milling that 3/8 inch thick white grid,
say by rubbing it back and forth on a sheet of rough sandpaper, or some sidewalk or
something, lol, until you got it down to about 1/4" to 1/8". After looking at that feeder
again, I think you could almost get away with it as is. As long as the grid was in contact
with the bottom board and seed could still be picked out under the glass edge. But
knocking it down in thickness by half would also work, if a bit difficult.
