I have just put up a fence but one of the posts has warped quite a bit in just a couple of weeks. It is concreted into the ground and is straight up until half way up the post (about 3 foot) and then bends about an inch into my garden.
I was thinking about getting a steel flat bar and attaching it to the opposite side of the post, the idea being that if the bar is rigid enough it will pull the bend back in. Just wanted to know if this is worth pursuing because a thick enough flat bar (maybe 5mm?) would cost at least twice the price of the post itself and I'm not sure it will even work.
Alternatively I wondered if using 2 steel angle bars on the corners of the post would achieve the same but I could get thinner (and therefore cheaper) ones as I'm assuming they will be more rigid due to the angle.
