Members TinkerTailor Posted October 31, 2016 Members Report Posted October 31, 2016 Only time in the oilfield i ever saw one fail at the stitching, they were winching a truck out of the ditch off of a couple of trees. They connected the loop to two trees at the same time with two chains in a Y configuration, because they thought one tree was not strong enough. The stitch failed right away, because the chains were pulling it apart. Thing is, all they needed was a shackle or a steel ring to hook the chains to and take the side load off the strap loops.

Yeah, I can see that. Technically, we wouldn't be allowed to use a sling like that because it is not proper rigging, but we all know stuff gets done the wrong way all the time. Quote
Members Tejas Posted October 31, 2016 Members Report Posted October 31, 2016 If with stretchy material such as webbing, the failure of stitches under load tended to be towards the the direction of the load, then sewing parallel to the edge of the webbing versus orthogonal to the edge of the webbing seems to be counter intuitive. Wouldn't breaking the end of a parallel to the edge stitch-line tend to compromise the entire stitch-line? Quote
Members TinkerTailor Posted October 31, 2016 Members Report Posted October 31, 2016 Not if the stitch has as much stretch or more as the webbing, both due to tension and similar materials. Nylon thread in nylon webbing should stretch close to the same. Quote "If nobody shares what they know, we will eventually all know nothing."
