The wall is semi-permanent; meaning that the legs that support the climbing panels can be detached from the base and swing to lay the entire wall flat. While it is very heavy, two people can move it fairly easily.
Step 1: Design
Your design should incorporate everything you want to get out of your training. For me, my gym doesn't have any steep overhanging walls, only vertical. Also, I wanted to mount my hang board and rock rings for general training. And as you can see, thats pretty much all I can do with this wall. Also, the Home Owners Association (jerks) have no respect for the wall, meaning there would be a chance I would have to take it down or have the ability to store it because of their rules for the neighborhood.
All the math needs to be correct at this point since it'll tell you what sizes to cut all your pieces. Several websites offer calculators to assist you with figuring out the missing angles and lengths of wood if all you know is your max height or the angle you want to train for.
Be careful making your wall TOO steep or TOO vertical. If it gets to be more of a ceiling then many affordable holds may become unavailable to you and if its too steep then you won't truly be preparing for outdoor climbing. This wall measures to 36.6 Degrees.
