Can anybody help?

Hi just looking at replacing our fence and have been looking at arris rails but have not worked out how to shape them to fit the posts,and cannot help thinking that some of the ones that i have seen seem to cut alot out of the post losing strength,would it be wrong to just measure the width between posts,cut to size and fix with nails?

Just nailing wouldn't be the best option, it's a rather weak joint for something that will have to take quite a loading from wind pressure.
Better option would be to use these

2x4 notched and screwed to each side of the post?

Cutting the V out of the post is not really an issue.

Have never had an arris fence post fail at the cuout, they allways rot away at ground level first.

Anyone else seen one fail at the cutout?

Come to think of it - no.

strength wont be an issue. Normally see them give way along the rail itself rather than at the mortice join. 3 angled cuts on the end and they fit in easy.

Quite right, the only failure I've seen at the cutout has been a failure of the fixings that is to say uncoated nails rusted through.

thanks for all the advice i will take it all on board,but one more question which is what are the pros and cons of a mortice joint over the galv arris rail cover?

 

[Thermo]

its stronger. basically once in there it wont move and it wont snap under high wind loading. Looks better too. The brackets are screwed or nailed in place with relativly short fixings and can come loose in the wind.

cheers Thermo!,so is the installation method set posts then install arris rails or is it a case of systematically working along the fence line

 

[Thermo]

systematically work along the fence line. dont forget the centre stumps/posts

(would have been funny to tell you to put the posts up first!(not impossible but hard!)

 

[fencing4fun]

Ha ha!,ok so last question how do i replace one in 10 years without pulling the whole fence down?

 

[Thermo]

firstly you wont have to. itll still be there in 20-30 years if done right. Are you talking arris rail or post?

little tinker thermo

If in 30 years time one of the posts rot off don't worry it'll be better to replace the whole fence by then so no problem. If you need for some reason need to replace just one that's also easy, just release the arriss rails upwards fit to a new post and push down and re concrete. But anyway by the time that happens you'll probably have forgotten this post.
