I know many have already talked about homemade parallel bars but, I have an idea and wonder if anyone has tried anything like this? I want to attach cables or a rope thru a PVC pipe (1 1/2" to 2" in dia) attached wall to wall (approx. 10ft. apart) with the use of anchor bolts / eye bolts in my wall studs. This should allow me to unclip / unhook the rope or the cable and set the bars aside out of my way when not in use. I definitely need the bars to be at least strong enough to do swinging dips. I think the idea will work but i'm wondering if they will sway around & require some extra support? Any advice would be appreciated before i give my idea a try. Or if anyone has done this already what did you do to make it work? Nick
