Attach Beam to Post and Level

What happens here

Attach the cut wooden beam to a vertical wooden post. Position the horizontal beam against the post at the desired height. Place a spirit level on top of the beam to ensure it is perfectly horizontal; make any necessary adjustments to achieve a level position. Once the beam is level, use a cordless impact driver to drive structural screws through the beam and into the post. Drive multiple screws, typically in a staggered pattern, to create a strong and secure connection between the beam and the post. Recheck the level after fastening to confirm it remains accurate.

Goal: Securely attach a wooden beam to a post and ensure it is level
