Cutting a Soffit Grove in the Fascia Board

What do you do when you need to replace a section of 1x4 fascia board and neither Lowes or Home Depot carry the pre-grooved fascia board nor the dado blade needed to cut the groove (into which the soffit board fits)?

You channel your Norm Abram from This Old House and recall that you can use a metal yard stick as a guide and make multiple passes with your skill saw to cut the required groove. Set the skill saw to the necessary depth and then slowly move the guide about a blades width for each pass.

Kind of a pain, and takes some time ...but it gets the job done.
