Lets see, about 20' of seat belt webbing, 2 "D" rings, a seat belt
adjuster for the chest harness (not the clip but the adjuster), 1' of 1" wide webbing, about 10' of hard braid nylon for prusiks. OK, I already had the locking carabiner but they are about $6.00 each. For deep pits, several of us pooled our money and bought 1200' of PMI 11 mm very low stretch rope. New rope has a waxy coating that makes it "fast" on rappels so it has to be washed. You can imagine the looks we got at the laundrymat stuffing 1200' of rope into an oversize washer (half in one and half in the one next to it with duct tape to disable the door switch.) PMI cost $.48/ft then. My cave pack was a $2.00 surplus gas mask holder modified with Fastek buckles. An expensive mountaineering pack would last only one trip while I still have my gas mask bag after 20 yrs. A carbide lamp was about $20 and a construction helmet about $5.00 modified with chin strap. Expensive mountaineering gear simply did not last on caving trips so we used ultra-cheap stuff. Surplus Viet nam jungle boots for $5.00 a pair would last maybe 20 trips. For cave clothing we wore either cheapo cotton stuff from goodwill or scavenged old disco era clothing for free. It had to be thrown away after a trip. This was the cheapest high adventure sport you could imagine. We went places and did stuff that far exceeded stuff you see in National Geographic. In later years, I am finally seeing pics of the places we went in National Geo. Cavers always look like crap covered with mud so no outdoor equipment maker wanted cavers as models so special made equipment did not exist (now it does much to my dislike). The one piece of equipment I used then that I use all the time for sailing is my old hand compass. Although it may mean little to him, I plan to say in my will that my son inherits it. |

You dont need the 1200' of rope to climb your mast, ok, maybe you could
rig every boat in the yard. |

One of my own "home grown" rules is never to come down faster than I went up. :-) |

How on earth do you possibly come to that conclusion? Commodore Joe Redcloud ....because I am an engineer with experience at making both kinds of materials. How else would I know?

Brian Whatcott Altus OK What a load of crap. 2" seatbelt webbing, 2 D" rings welded by some guy who has no idea what they will be used for, a foot of 1" webbing fashioned into some homemade sit harness by some Chouinard wanna may be stronger (not!) but I'd go with the UIAA tested, warranteed, insured stuff made by some reputable company who has made tens of thousands and continues to enjoy good success rather than the trailer park version. Gaz Still climbing and sailing - same gear. |

Brian Whatcott Altus OK On Sun, 25 Dec 2005 01:23:24 GMT, Gary came back with this reasoned evaluation: What a load of crap. 2" seatbelt webbing, 2 D" rings welded by some guy who has no idea what they will be used for, a foot of 1" webbing fashioned into some homemade sit harness by some Chouinard wanna may be stronger (not!) but I'd go with the UIAA tested, warranteed, insured stuff made by some reputable company who has made tens of thousands and continues to enjoy good success rather than the trailer park version. Gaz Still climbing and sailing - same gear. That is of course, your option. And if you don't have the requisite background, it is usually an EXCELLENT idea to go with the more expensive choice. Fortunately, I am not limited by the concept that bucks = safe in quite the same way. That doesn't mean you're talking crap and projecting. It doesn't mean you're dumb with judgment to match, I have got several pro harnesses, an industrial harness (far FAR stronger than anything you've got) and several swiss harnesses (home-made by a guy who knows what he is doing) and I can evaluate relative strengths. What have you got, besides gut-feeling? Brian Whatcott |

At least this response avoids another personal attack. Not even a whisper of back streets, gutter-snipes, trailer-trash, etc., etc. So in return let me explain. I will be brief, mostly because I don't much care whether you understand or not. The UIAA is L'Union International des Associations d'Alpinisme. They do a worthy job in underwriting technical safety of climbing gear. Technical gear found its start in the back streets of enthusiasts, in a manner of speaking. A nut was called a nut because a guy at Rolls-Royce (I think it was) threaded a stainless loop through a machine nut. The people who dreamed up technical stuff were either engineers, or took careful advice of engineers. But there was a conflict (not uncommon in aero engineering in fact) between lightness and strength. So testing and traceability were imported from Aero engineering practice. This is expensive. Because the trade is low-volume. The lower cost route to engineering reliability (and engineers are always interested in the most bang for the buck) is generous NOT minimum safety margins. That means the devices are heavier, and nearly always stronger. So if you want the very strongest device like a climbing harness you DON'T choose a UIAA type device - you specify an industrially rated device that is specified for abusive use under legal constraints. But it's not everybody that wants such an awkward harness with huge buckles etc...... so there is a middle way. An engineer is the job description of someone capable of doing this sort of material specification. Get it? If not, you'll need to look for someone else to continue this discussion, because you've taken all the pro bono time I'm willing to offer you. Hasta la Vista Brian Whatcott Altus OK |

Hasta la Vista Brian Whatcott Altus OK Remember the beginning, a comfortable harness to climb a mast instead of a bosun's chair? We recommended climbing harnesses and you started to overbuild (2" webbing etc). A climbing harness built to withstand a fall of twice the length of a rope, and not fail, is already way over built for holding you up a mast. Essentially top-roping on a 50' pitch, right? Anything more is plain silly. That is pro bono common sense. I know what UIAA is. I know the history of nuts (actually started with chock stones, then nuts - Joe Brown era). I know what engineers do. Space shuttle, Tacoma Narrows bridge, Titanic....... You climb in your homemade harness, I'll stick with stuff tested by real engineers. Think about that after you pop off wearing your seatbelt webbing and 2" D rings. Get it? Gaz |
