Fixing Timber to Fence Post

[cosmarchy]

Hi,

I'm trying to work out how to fix timber (to mount a gate) to an intermediate concrete fence post...

My thinking is to add fixings as shown in the image but I'm not sure there is enough meat there and the concrete may well crumble away. I'm also sure there is some re-enforcing in there somewhere and such I'd probably not get enough depth before hitting it.

My other thought is to put some 2" x 3/4" wood in the recess and fix through the middle of the 'H' but that would depend on getting timber the exact depth and I'm not sure whether this is possible - I'd rather not have to rip some wood down to make it fit as that would remove any tanalising or other protection the timber may have.

How is this normally done?

I can't see your pic.

you can get metal brackets that clamp round a concrete post

i am not in favour of drilling them, because you might start a crack, or in some cases drill through the steel reinforcement or remove enough of the covering to promote rust.

steel brackets are best painted before installation, because they will be exposd to the weather for a long time, and will rust.

A common way is to infill the recess with wood and use through bolts and then screw support post to this, however, you could leave the recess 'open' and secure the support post through the centre of the concrete post using threaded bar. The nut on the wooden side can be recessed flush by drilling counter bore holes to the depth of the nut/washer and with a diameter large enough to accept a suitable socket head for the nut.
