Hi, I'm still plugging away at this run I'm building. I built the door and decided to make it solid using scrap 2 x 4 's and 3/4" planks from left over materials. The door looks great, but it's very, very heavy! I just purchased 18" heavy duty strap hinges and 3/4" pins to put through the posts, which are 4 x 4 (actually measures 3.5 x 3.5). The gate itself is 6 feet tall and 3 feet wide. I'm now worrying that the post isn't beefy enough for such a heavy gate. I have no room to put a post in next to it since it's in concrete. Do you think it'll be okay or should I scrap my scrap door and build another? I CAN cut some out of the top and add a piece of Lexan I have, that would take some weight off, but not much. Thanks!
