'Reverse' concrete form?
I realize the title might not make any sense, but I just can't think of how to better describe this in a few words... Here, I have more space though!
What is the best way to make a concrete block that once cured will receive a 4x4 post, as an example?
I'm guessing like many here, I've dug my share of post holes, poured concrete, and dropped-in 4x4's in putting-up fences. I'd like to have the option to later easily slide out the fence posts, for a few reasons I suppose that are not exactly pertinent here. Not sure the best way to make this happen.
If the best way to do this is simply to use a 4x4 post and remove it at some point, exactly when, as doing so too quickly or waiting too long makes for problems...
Thanks for the input.
