Does he realize how close he is to shredding that webbing? Based on some rough estimates, I assumed: 1) the webbing going to the anchors is at an included angle of 170 degrees (the higher the angle, the higher the loads); 2) he weighs 170 lbs.; 3) the breaking strength of the webbing is 4,500 lbs.; and 4) the knots in the webbing decrease the strength 20% to 3,600 lbs. From this, I conclude his weight exerts a tension in the webbing of almost 1,000 lbs., and the tension is 2,500 lbs. A fall and subsequent dynamic loads would surely break the webbing and his "safety line" would be worthless. May I suggest the following for Dean and others wanting to try this: 1) Don't tension the webbing so tight, 2) Have someone belay you from the side in addition to the safety line (better a nasty pendulum than cratering), and 3) use something stronger than 1" webbing.
