Mr. Doubtfure hires me to help him out on his contracting business. Edward is a good friend and he allows me to sub-contract my services to his clients. The job details are quite simple. The redwood fence had 4x4 wooden posts and some had been replaced by metal fence posts.

This post shows the seven steps on how to remove a wooden post and install a galvanized metal fence post inside a wooden fence.

Step 1: Evaluate the fence, decide which metal fence post needs to be replaced. In this job some of the fence posts had rusted at the bottom of the cement and needed to be removed and replaced. 
Step 2: The kit needed to mount the metal fence post to the wooden fence. These kits were already in use when the post was replaced. The kit can can be purchase at Lowe's. The kit is a Galvanized steel chain-link fence wood post adapter.
Step 3: Fig.1 shows the galvanized steel chain-link fence dome cap needs to be on each fence post, the reason is that when it rains water will enter the pipe and slowly rot the post from the inside. Some dome caps are a little loose, drilling a self-drilling screw inside the cap perimeter will keep the cap from being stolen and prevent water from getting inside the post. This post has a diameter of 2-3/8-inch this makes it stronger in wind conditions.
Step 4: Fig.2 shows this posts are secured by a metal band, part of the band is attached to the metal bracket and the metal bolt secured the bracket. The bracket has square parts that allow the galvanized carriage bolt and nuts to secure solidly to the post.

Step 5: Fig.3 shows another angle of the chain-link fence wood post adapter.

Step 6: So how does the post get into the ground? A Master Halco Chain-Link Steel Post Driver made of Galvanized steel, is 24-inches in length and is used for driving posts into the ground. This one was purchased at Lowe's. Think of this like a hammer nailing a nail on a wood stud, except the hammer is the post driver and the nail is the metal fence post. Fig.4 and Fig.5 shows the metal sledge and post driver can also be used, but what usually happens is that the top of the post needs to be cut because it's deformed by the slamming of the hammer on the top of the post. Fig.6 shows this post has been slammed into the earth.

Step 7: But what holds the fence post into the soil? Well before the post can be driven into the soil, a hole needs to be dug and Quickrete 50 lbs fast setting posts concrete mix (also purchased at Lowe's) used. Pour one bag of concrete mix into each hole where the metal fence post is going to stand. Now the job is finished. This job took me a better part of one day. Fig.7 and fig.8 shows the job is done. Now the job is finished and Edward can tell his clients that their dogs and various barn animals are safe from neighboring coyotes.

Below is a quick recapitulation for one fence post hole.

Step 1: Remove the old rotten wood post and replace it with a 2-3/8-inch metal post. 
Step 2. Remove the old cement and place it in the trash can.
Step 3: Dig a new hole.
Step 4: Ram the new fence post into the new hole.
Step 5: Place a bag of Quickrete Posts Concrete Mix into each hole.
Step 6: Level the fence post and secure it until the cement dries.
Step 7: Once the cement has dried, screw the post to the fence using the Carriage Bolt and Nut.
