Hi All, I'm in the process of building my own climbing wall in the alley way between my house. It will be a 4.4m x 3.5m flat wall. That will ultimately be a circular circuit. With a campus board at the end. I'm building one because the bouldering wall is nearly an hour away and sometimes I can't get there so this wall is intended to train strength, endurance and technique on my busy days. I need advice on the following: I'm building a frame that will be attached to a brick wall. The frame will be 4.4m long and 3.5m high. So I'm opting for 2x6 timber. When I've built the frame what screws do I use to attach it to the brick wall? Because the frame is built like a stud wall the timber will be on its slim end so I have to get through 5 1/2" of wood before I'm into the brick. Also the alleyway has slabs, with a gap either side of about 2" where there is mud and stones for drainage. I've built a roof and waterproofed it to protect the wall. But how would I attach the frame to the floor? I'd post images if I could but this forum doesn't seem to let us. Any help would be greatly appreciated.
