fencepost
I removed a rotten 4×4 post that was used for a fence. The concrete hole seems sound. I was thinking of putting a 2 3/8 metal pole in this 4×4 hole and then filling with concrete.
I am not sure if there would be enough new concrete around the metal post to make a secure fit.
If this works I will probably replace all the 4×4 wood posts with metal posts.
Any ideas or previous experience around this would be appreciated.
Since you just want to get the fence back up: screw a long board horizontally across the pieces of fence, bridging the broken post. A couple of long 2x4's should do the trick.
Skip fixing the post altogether.
The main con is that since its designed to be driven down, the tapered tip will offer less torque, even set in concrete, than a post set to a similar depth.
Another consideration is frost heaving. The bare adapter should not heave, but the combined concrete/adapter might, unless the pour goes below the frost line. This can be mitigated with SONOtubes use.
I wonder if using 2 ez-mender, set in concrete, might not give a more stable base.
(from the website: "Post bases do not provide adequate resistance to prevent rotation about the base and therefore are not recommended for non-top-supported installations such as fences or unbraced carports")

You'll have a hard time getting concrete into a 1" gap. You'll want to either enlarge the hole slightly or use a loose sand mix concrete, which will likely crack up, but should retain the post adequately.
