Rafter Preparation and Marking Techniques

The video tutorial provides a step-by-step guide on preparing and marking rafters for construction. It begins with crowning the rafter and marking it using a framing square. The tutorial then explains how to shorten the rafter by half the thickness of the ridge and mark the second plum line for cutting. It continues with measuring and marking the rafter's length, followed by marking the bird's mouth and heel line. The final section covers making adjustments and marking the overhang tail caput. Throughout the video, the use of a framing square is emphasized for accuracy.

• With the top edge of the board

• With the bottom edge of the board

• With the side edge of the board

• With the center of the board

What is the purpose of shortening the rafter by half the thickness of the ridge?

• To ensure proper alignment

• To create an overhang

How do you determine the seat cut measurement?

• By aligning the framing square with 10 1/2 inches

• By sliding the square until it hits 15 1/2 inches

• By measuring the length of the rafter

• By marking the second plumb line

What is the final step in marking the overhang tail?

• Align the square with the center of the board

• Mark on the left side of the tongue
