Gate posts.

[f1steveuk]

I have two gates to install, approx' 3 feet high, and approx' 14lbs each, I want the post to be one foot higher than the gate, so four feet posts, added to which,  how much under ground??? two feet in concrete, therefore  six foot posts? There's no bracing and no fence to add them too, so it's a hole in the ground and ballast and concrete.

Yes, I've always understood it to be "one part underground, two parts above".

Whats the total opening and therefore the size of each leaf, and what size gate posts were you thinking of using? This will greatly affect the depth. If the leaf's are quite wide, you will also get quite a bit of sag on the post alone. Let me know the dimensions and I'll try and help a bit more.

At about 6kg each there can't be much substance to them.

I think I should wait until I get home (12th Dec) and weigh and measure these gates! Watch this space, but a ratio of 2/3s above, one below seems about right, but I have a habit of over engineering every thing I do!

Over engineering or do it once, do it right. I'd agree with the 1/3 2/3 ratio, I install a lot of site gates(2.4m high, 3m wide 50mm box clad in weld mesh) and they go 0.9-1m in the ground on a 150x150 post. They never move, until a muck-a-way lorry somehow doesn't see them!
