When testing ropes, cords or webbing, you should consider having "tensionless" fixtures on each end of the piece being tested. For rope testing, manufacturers use a non-rotating thick wall steel pipe that is many times the diameter of the rope. They wrap the rope at least 5 wraps, laid next to each wrap, and then anchor off the end with a knot or clamp. By doing the testing this way, the ultimate tensile strength of the rope is revealed, instead of knot strength, because the bend radius is shallow enough to distribute the load throughout the fibers, and there is enough wraps to reduce the load way down at the final knot or clamp. Thus for your "Sharpie" test, you might be able to see that the chemicals weaken the rope's ultimate tensile strength.

As a process engineer i'd like to say that this is a great idea, and also state that material compatibility testing is more comprehensive than this. It would probably involve soaking a rope in either material (sharpie ink or the rope marker material) for different timespans, say 1 hour, 1 day, 1 week, 1 month, and testing at those time intervals. Of course, you also have to perform a measurement systems analysis beforehand and establish your confidence intervals. Based on standard deviation between samples of fresh rope (your control), you can estimate the sample size needed to establish variation in the mean break values. The stress/strain curve will have multiple outputs from tensile strength to elongation &c &c. Thanks! cool video!!!

A few years ago I spoke with a Sterling Rope production manager. When I asked him about this topic his answer was, because the recipe is not the same for every batch of ink produced, meaning any two Sharpies contain different chemicals and compounds, they cannot make any blanket statement of how sharpies will affect a rope. So it could be totally safe, or it could damage your rope and the only way to find out is to test Sharpies individually.

Chemical resistance is a combination of time/temperature so it might be interesting to do something over a period of time at temperatures that simulate a closed up car in the desert. Additionally, it is pretty common to do an accelerated chem res test under strain. The fact that the solvent is essentially gone might negate the effect but this would be more of a real world test for the sharpie. I suspect that sharpies aren't too bad considering they are alcohol-based versus something like acetone in nail polish. Some other ideas on things to test from a chem res perspective would be DEET, picaridin and water, if they haven't been covered in previous videos (there are so many it's hard to keep track)

See if you can find fluorescent orange (yellow, whatever contrasts the rope color) and apply a thin coat so the white can glow through. I was amazed at how much brighter the white base makes the top coat. Might take some experimentation on rope. EDIT: I’m back with a highly visible bizarre idea.

Seeing the creep in the end of that rope makes me wonder why folks have gotten away from whipping the ends like used to be done. You can even use hi-vis thread to make a very easily seen end. While I can't say that whipping would stop the rope creep, I think it would certainly help. Relying on the "butane backsplice" or super glue is great, but even a common whipping would add yet another layer of insurance and is easy to do. Also, painting the ends is great, but if you want a real bright finish, paint the rope with white paint first. When you go over that white with the prettier red or orange, you'll see a huge difference in how bright the topcoat is. Old trick used to paint rifle and bow sights.

Or if you want to be extra safe you could make a test length like this a completely soak the test portion before letting it dry and performing this test to determine if any amount would cause an issue.

Box stores tend to have only one viscosity of superglue. I wonder if you’d find it any easier to soak the ends with a thinner glue. I’ve found that hobby shops tend to have cyanoacrylates by Bob Smith Industries. Woodworking shops tend to have products by FastCap. Both have at least four viscosities. Both also sell accelerators that nearly instantly set the glue, with the supposed detriment of a marginally reduced strength. They sell conventionally sized bottles and significantly larger bottles, which could be a benefit if you’re doing large batches. If not, it’s kind of a liability because the bottle can get pretty crusty, despite the higher quality glue being more stable over time. Cheers.

The issue isn't really whether a Sharpie deteriorates the rope or not. The issue is more about altering the rope. Each manufacturer of ropes has extensively tested their product under a variety of conditions. At least I hope they have. The product will then be certified and guaranteed for those conditions. If the rope is altered in any way, then the manufacturer cannot guarantee their product because they don't know if it has deteriorated or not. As far as Sharpies are concerned there are hundreds of different types of permanent markers and since the manufacturer cannot test them all, they won't certify any. So what they can do is certify something specifically designed and sold as a rope marker, even though it might be exactly the same ink as a sharpie. Now that all said, it is wise to actually check with the manufacturer to see what they say as far as marking ropes, rather than assume one rule applies to all. Some might actually have approved sharpies for use while some might say the opposite.

It would be interesting to see what the fibers look like under microscope to see what if any impact the ink has. As well, soaking in various solutions like cat pee, gasoline, oil, puddle water…etc then see how the strength of the rope is or isn’t effected. Just to demonstrate a video on carelessness of rope and the effects.

I just run fluro floss through the loops of the mantle in a spiral. Visible enough, and kind classy.

How long did you wait between saturating the rope and testing it? Also, I liked the dual-location format.

I just simply use some thread to mark the middle. Wrap it around and it holds pretty well. It has to be redone every year or so, also sometimes it can catch on stuff if you do it incorrectly. Otherwise I find it very astetic

Be nice to test it after the ink has been on for a few weeks to see if it degrades the fibre over time.

Awesome video as always. Just wondering why you didn't use a friction knot? It wouldn't compromise the rope at the knot then. Is supposed to take it alot closer to it's real breaking strength. Also I like the multi location of this..... You need to up your gear wall 😉

Haha exactly! I’ve marked my ropes for years. But it’s cool to know the science

Side note I just noticed the plaque on the top right of the gear wall. I've got essentially the same one. Looks like someone's been the Philippines, at least that's where I got mine...

I suppose the break test would have more validity if you let it sit for a few weeks/months after appying the ink. And also if you performed a test applying force specifically on that spot.

That's an awesome idea about using electrical tape and using super glue. I was always pulling my hair out because I couldn't melt the ends of my ropes together neatly.

I was told that sharpies cause the rope to degrade faster, so perhaps the issues would be a few years down the line. Not sure if there's any truth in that, though.
@kevinmokracek50782 жыл бұрын
Sharpies have been used as long as Sharpie has been around and there has never been an incident where a rope broke or the sheath deteriorated from its use. I think the myth that it will destroy ropes was propagated by companies that make rope markers.

@@kevinmokracek5078 likely true. But to test it, one would have to use a rope that was marked a while ago.

@@kevinmokracek5078 The biggest concern is affecting the UV resistance of the rope. Also, black ink means it would soak up more heat, potentially causing issues. But the chemicals themselves are nonreactive with nylon, or really any other material that ropes are made out of
@alexandreleblanc9582 Жыл бұрын
are wet ropes weaker? I feel like it cant be the case, otherwise rain=death... thus, unless there's a chemical reaction between the plastic of the rope and the ink, there shouldn't be a noticeable change in strength, that's my guess
