Actually, to groove 30 slots that are .156", with the same distance
between each groove, would result in 30 grooves in about 4-3/4" of
material.

30 x 0.156 (5/32") -- ~15/16*5 is the width of the grooves alone--it
would take twice that to have 30 slots plus the same distance between them.

Ok, I did some checking and apparently ".156 on center." means the
trace in combination with a space is .156.

Therefore .078" is the actual size that my metal strips will have to
be.
