4. Pull any nails that remain in the corner after you remove the corner bead. Use a nail puller and a hammer to extract the nails. Do not be concerned with damage to the corner drywall during this process, as long as you confine the damage to 2 to 3 inches from each side of the corner.. Cut into the corner with a hack saw at the mark. Hold the hack saw parallel to the floor as you cut into the corner. You must cut through the existing metal corner bead completely.
Please remember, cooking times are not exact because of differences in ovens and roasts. Also, the roast will continue to cook for a while after removing it from the oven. My 5 pound New York Strip Loin took a full 2 hours, roasting as above. It was a perfect temperature (just between medium-rare) all the way through. I removed the roast when the thermometer read 135 degrees F and it went to 140 degrees F while standing.
Stick the probe into the center of the Strip Loin and set the alarm for 120 degrees. Close the lid and let the pit roll. For a roast this size it takes a little over 2 hours of cook time at a constant 250 degrees. When the alarm sounds, verify the center is 120 degrees.
