Fence post

I’d imagine you’d need a bigger hole and more concrete too. Seems like a bigger pain the arse, but I suppose it depends on how much fence.

Why are you using wood posts? I used square (4" square x 14 ga) tube painted black and did a similar design to what it sounds like you did. Post is visible from both sides.

I do weld and used angle iron to attach the posts to the rails. So that may not be an option. I do like the way it looks though.

I built a friendly neighbor fence about 20 years ago about 150’ long.
While doing my homework I read that instead of going with a bigger post every so often go twice as deep every 6th the post.
The fence is 6’ high. Post were spaced 6’ apart. I started with a 10’ post cemented 4’ deep, then 5ea 8’ post at 2’ deep.
Repeated this process for the length of the fence and put the other end post 4’ deep.
2x4 runners with dog eared pine fence boards.
Has held up through the years, only replacing a board or two every few years.
