Rout the Notch in the Decking Board

What happens here

With the notch area clearly marked on the composite decking board, use a cordless router (specifically a Makita 18V cordless router is shown) equipped with an appropriate router bit to carefully cut out the marked section. Guide the router along the marked lines, making multiple shallow passes if necessary, to remove the material and create a clean, precise notch. Ensure the board is stable and secured during this operation to prevent movement and ensure safety.

Goal: Create a clean, precise notch in the decking board
