I recently put a fence and didn't quite think it through properly. I used a 75mm post for a gate supports and it really should have been bigger (you live you learn). Although it won't fall down it does have a slight wobble at the top when closing the gate. I am considering methods for strengthening the gate without replacing the post (which the wife will go nuts about as she's been waiting for the fence for a while).
I was considering either putting another post against the gate post or using a bit of metal angle iron or similar and strengthen that way.
I was hoping someone may have an idea as to what would be best and where I would go to get the metal if thats the best way.
Any others ideas would be appreciated.
