This shows at the Buzz for 40 pages of insights and also some warnings from TreeStuff as well.
Moss's hand sewn process
.
Not a splicer, but my take:
TreeStuff Bonner's concerns point at some things etc. To differentiate a splice would get frictions all around inside a shrinking 'tube', then stitched and many more made and can be machined away from human f'ups. Totally different than 1 side frictions, no shrink around and stitch by hand that quite possibly a teenager in a rush might try, even gift to someone...
.
My interest academic and safety only a sprinkle of self sufficiency. i think that the frictions/adhesion is the property to watch, 5# added thread strength a secondary concern for when it all hits the fan/threads pulled diagonally as the friction mating hookup is surpassed and eye goes to backup strategy. A way to test the theories i think would be to make lesser splices instead of better for testing for built in headroom and to prove theory. Like if usually throw 100 stitches in, try 30 and test. If that even comes close to acceptable, would seem bringing back to 100 stitches very confidently and go on. Kinda a reverse strategy to same point, round world view. 100 stitch count not total focus, the linear length of the 'tacking surfaces' is how frictions are compounded.
.
My knot view of Hitch terminations and Bend couplings are that they are external linear force fed into arc control(Binding is internal radial force to same arc controls w/o linear to radial conversion). The first, Primary Arc whether 90 or 180 forms a hook to the preceding linear/Standing Part in Hitches and Bends. Rest of knot is to keep this hook aligned in place on host hook keeps load connected. By that model, after the hook in this 'hand sewn eye process' is the frictions tacking to side, and some lil'baby shelves of texture catching on each other as long as this stays in position, the hook is good,. This is dependent on the frictions imposed by the thread mating the surfaces tightly, on a linear run the frictions will compound by distance of contact so that is factor, so is the slickness of the materials and their manufacture/braid. The way the braid catches itself or not might surprise in a different kind of rope handled same. And the slickness of the material used then of course too. So this would still be more towards select fire not shotgun all across everything with claims of what works.
.
Clear coat would help keep this simple alignment, keep colors brightest for most dramatic inspection, protect threads and keep grit out from working it's way inside to work on cutting fibers unseen from the inside. This would seem more like a buried splice concern, but is additive here that get with the protection of the sheathing. Cleaning carpets makes them last longer, as sand model is 18 cutting surfaces per uncrushable grains deep in carpet powered by people walking back and forth etc. silently destroying carpet from inside.
.
The warnings on the threads getting slanted under load is what i envisioned. This would be the place where raw tensile of thread x numbers of threads is more of an argument necessity. This would also be the time when would want thread more matching the host material so neither had the advantage to cut the other etc. Similar to Square Knot needing matching materials for even fight to maintain Square-ness. Otherwise, in normal use, the threads sitting 90 degrees to rest of rope are just for the side adhesions/frictions . Thus still feel some non stiff, non destructive glue could help on that facing. ABoK talks of putting fresh varnish on mast area and then knotting on that for extra tack in the lengthwise pull chapter (which this is), other ways were to use wood ashes, best he recommends is cut open inner tube to use thin rubber to alter the CoFs Co-efficient of Friction of the mated surfaces.
.
So i maintain my fender washer model, for hanging sheet vertical. Pinch with bolts across, but held in place by frictions of fender pinches invoked by bolts. Don't want it so much hanging on bolts, and in use the holes elongating or any wear as a safety flag not carrying on simple frictions and stressing across the bolt minimal not maximum size dimension. The fender washers spread stress to wider area while using bolt force properly, even tho not aligned to the load force but across. The best strength of the thread is pulling along it's length across eye, to then leverage the frictions into holding eye. Not eye losing these frictional catches and actually pulling across threads where they have to slant trying to hold on by aligning with the force pull of rope as can as a last bailout resort before failing.
.
Too small an eye could get spread by host against the first thread 'tack'. Longer with preceding tack, space, then real list of stitches kept safe from spread by tack riding point could be improvement. As first position to slant, perhaps this could be softer thread, less cutting primary type model if slants. Eye long enough to Girth/Choke to carabiner would take some strength concerns off stitching and realign concerns to bend against the Standing Parts of eye, and this should not be stiff if going this route. Rigidity invokes leveraged length, loaded soft parts will already give this, thus efficiency/cosine loss. Stiffer/stiffened material will emphasize this.
