Hey,

Does anyone have any ideas on how to cut a 3-inch wide and 1-inch deep
trench into the face of a panel of EPS foam insulation?

It should travel vertically up and down the 8-foot high face.

Any ideas welcome.


Is the insulation 3 (or more) inches thick? If so, using a tablesaw,
rip the panel into 2 pieces. From one piece rip a strip that is 1 inch
less in thickness than the thickness of the panel. If necessary, rip
this piece down to 3 inches. I know this won't give you a single piece
with a trench or dado, but the 2 large pieces, with the narrow strip
between them, will probably work OK unless you have a real need for
single unbroken piece of insulation in your application.
