Marking and Cutting Picture Frame Border Track

What happens here

To create a contrasting picture frame border, the main field deck boards need to be precisely cut. First, use a tape measure and a speed square to mark a line 12 and 7/8 inches from the edge of the deck, ensuring consistency. Snap a chalk line across the deck to create a straight cutting guide. Then, use a track saw to make a clean, straight cut along this line. This cut will create the channel for the border boards.

Goal: Prepare the deck surface for a contrasting picture frame border.
