Concrete corner fence post and angled fence

[Cellophaneskies]

Hi all

I’m putting up a fence using concrete posts and wooden panels. One corner will receive a straight post into a corner post. And then the other post off this post will be at an angle more extreme than 90 degrees as the other end of the fencing terminates about 20cm or so away from the corner posts.

I’ve attached a horrible scrawled diagram to illustrate this.

I assume I’ll ‘just’ cut the fence edge in such a way that it will slot into the concrete corner post at an angle. Might be lucky, the fence panel is feather board so the individual boards might sit just right. Or they might be an arse.

Anyone had this issue before and reached a solution?


I really want concrete posts for longevity and so I can use gravel boards, nicely, but the non-straight nature of my garden is making it awkward..

Can you use two posts? Or fix some timber to the end the panel at the correct angle to slot into the post.

Can you use two posts?

Other than the aesthetic reasons - having a triangular gap between them- I don’t really see why not. How do they fare being in the same post hole together, in terms of their footing etc - or would mean less coverage at the point where they meet in the ground

you say 20cm away ??
would that not be easily filled by a carefully placed second post and a full 150mm gravel board with or without a chamfered edge to sit in comfortably ??

sorry I was unclear there. The fence run is about 5m and one end is 20cm offset from the other. So over the course of 5m it moves 20cm diagonally from the first post

I think the gap at one end is a different point from the slight angle.

I have a fence that does not quite meet the end of the garden, I used two wooden posts to fill the gap. They are slightly raised so hedgehogs can get through.

I can't calculate how many degrees out of square your corner is. You could perhaps make a wooden batten that slides into the concrete post and has a sawn or planed angle on one side, with galvanised clips to fit the panel.

You say the fence is feather edge so you could make up a wooden frame to fit and nail boards to it. You can probably make it better than the prefab panels. You could even make a frame and hang a panel on it.

Thanks. I could go this route.

I still thinking I’m describing myself poorly. Let’s say first post is against the house. The end post and the final part of the fence run is 5m away but it is 20cm right of the house. That’s dictating the angle i need the fence to run at!

So you have a triangle with sides of length 500, 500, 20

In builders terms, the out of square angle is negligible.

I can confirm exact measurements tomorrow.. do we think this angle is so small as to not really pose any issue?

 

[JohnD]

I think the angle is about 2.3 degrees out.

Too small for you to see.

I never liked trigonometry

That may be the first time I have tried to use it since I started wearing white shirts.

It’s actually about 30cm so my estimate wasn’t wildly off..! So you think the angle that gives me is very very shallow.. so I might get away with this with the panel in the slot as normal. Gravel board to contend with too..

With a 30cm difference the the angle is 3.43°, I agree you'd get away without any issues, just position your post so its half way between. Also some (most?) concrete fence posts have a slanted slot which will accommodate a bit of tolerance.

Thanks. This will be a corner post receiving another panel with no angle so not sure I can give it much twist/a twist in the angle might look a sod. But here’s hoping I can simply get away with it..!

You only have to twist it by 1.7° then each fence panel/gravel board can surely cope with that.
