How To Make A Mailbox Post

If you have a mailbox that needs a new post or you want to make a custom one, then you’ve come to the right place! In this article, we will go through the steps of how to make a mailbox post.

Materials Needed to Make a Mailbox Post

Before we start the instructions, let’s go over the materials you will need: – 4×4 pressure-treated lumber – Circular saw – Tape measure – Drill – Screws – Post hole digger – Concrete mix – Water – Level

Step 1: Cut the Lumber

The first step in how to make a mailbox post is to cut the lumber to the desired length. You should have four pieces of 4×4 lumber, each about 6-8 feet long. Use a circular saw to make the cuts.

Step 2: Dig the Hole

Next, you need to dig a hole for the post. Use a post hole digger to make a hole that is about 2 feet deep and 1 foot wide.

Step 3: Mix Concrete

Mix the concrete according to the package instructions. You will need enough to fill the hole about halfway.

Step 4: Set the Post

Place one of the 4×4 pieces of lumber into the hole. Use a level to make sure it is straight. Then, pour the concrete into the hole, making sure that the post stays level.

Step 5: Repeat

Repeat steps 3 and 4 for the remaining three pieces of lumber. Make sure that each post is level and straight.

Step 6: Secure the Posts

Once the concrete has dried, use screws to secure the posts to each other.

Step 7: Add a Crossbar

To add stability to the mailbox post, add a crossbar between the two front posts. Use screws to secure it in place.

Step 8: Attach the Mailbox

Attach the mailbox to the top of the crossbar using screws.
