Altoids Sours BBQ Grill

Step 3 Upper grill notches

Using the snips and the large fan grill as a template, cut 4 small slots in the rim of the tin.  These should be thin so that they will grip the upper grill but not so much that the grill can't be removed.  Needle nose pliers come in handy for removing the metal after you snip the edges.

When you are done test fit the large grill and make sure it snaps in and out nicely.
