I'm going to build a wood fence along a house. I was hesitating if I could do it myself, but after checking the prices at https://fencingspecialists.com.au/ I'm eager to try. I've never done this before, however, I like working with wood, so I think it won't be any problem. Also, I believe, that the idea with rail brackets is good, so I will follow your suggestions here guys. I wanted to ask about the holes - how far down to dig? And how much concrete to use for each post?
