What size post and what depth would it need to go to to support the weight of a gate like this? What about hinges?
I was thinking a couple of 1m hook and band hinges. Not sure on the post size and depth though.

750 deep should be enough depending on the ground
would go for at least 300 by 300 of concrete though

Doing his PhD in physics... quantum loop gravity or something.
Only occured to me yesterday that he could answer it. Gave him the measurements, he calculated the torque etc
Handy for that, not so handy when I had him out labouring and he tried to push a wheelbarrow full of mortar up a step instead of pull and he dropped it all over the slabs I had just laid :laugh:

what kind of gate is it and how heavy is it. For a light fence or field type a 6x6 inch post will be fine. For a heavier gate then you'll need an 8inch post buried up to 3ft deep depending on the ground. It's unlikely you'll get a 2.8m 6 or 8 inch post from stock so it would be a special order from a sawmill that can do pressure treatment.

It wills be a heavier gate, Z frame but he wants some privacy so it will be quite heavy.
Going to get in touch with a few sawmills / timber merchants in the area and pick up a 200x200x2700 post. Cheers for the advice.
