Cut V-Groove with Router

What happens here

Position the router within the guide rails, ensuring the V-groove bit is aligned with the previously marked center line on the composite siding. Adjust the router's depth setting. It's recommended to make several shallow passes rather than one deep cut. Turn on the router and carefully push it along the guide rails, cutting a V-shaped groove into the siding. Repeat this process, gradually increasing the depth of the cut with each pass, until the groove is almost completely through the material, leaving only a thin layer at the bottom, which will act as a hinge.

Goal: Create a V-shaped groove in the composite siding for folding
