I'm thinking of building something at home for climbing. Most plans for home climbing walls I've been able to find have elaborate frames attached to the wall of whatever (garage/basement/etc) OR they are free standing. I don't have a ton of room to do either of those, but I have a wall in one of the rooms of my home that is already at a good incline for bouldering. I'm wondering how safe it would be to attach my wall (plywood panels) to my existing wall studs using a minimal frame? Those of you with construction/home building experience, any thoughts?
