This is a great video because you tested your results experimentally, so the glueing/sewing method has real value. Your opinions are backed up with actual measurements. Worth much more than untested opinions! Thanks for putting so much work into the video demonstration. Anyone (like me) who is making their own tent or tarp will find your video very helpful.

Thank you for your effort. It helps many people a lot including me.

this is a great video!! i'm going to be gluing the silPOLY when i get that stuff to make my personal shelter/tarp. thanks for sharing your experiences!! much was learned!

Excellent video! You applied your technique and tested it. Here in the USA finding Wacker E41 is difficult in small quantities. I have found something very similar though, and cheap. It is Permatex "flowable" windshield and glass sealant. I plan to test it with more coarse nylon materials like webbing and cordura fabric to see if the additional air space from nylon webbing threads weakens the adhesive bond. So much nylon fabrication is going to "welded" bonding and laser cutting, I want to find a cheap DIY alternative to that expensive equipment.

If only all test videos were done this professional :)

Thanks for investing the time to share your knowledge and experience. Your technique is going to be employed for an upcoming silnylon shelter!

Love that little prototype tarp! Very interesting video, thanks

Excellent method..thanks abunch for posting good stuff.hope u show more projects in the future?

Thanks Samuel for the informative video! This got me into using glue for most of the seams on my tent. I've got pu-coated polyester so had to find another glue but elastic vinyl glue worked out and the result were similar to yours. Thanks again!

Well said! I had the exact same concerns. Sadly I wished there was the glue for perpendicular stress.

Hey its been 3 or 4 years now. Can you update us (me)?

Excellent. Looking at the pull test at the end of the video caused me to wonder how the seam would react to a sharp force as opposed to a gradual increase in stress. Just sayen.

thanks for the great video. much appreciated!

Just looking at your lateral vs perpendicular stress testing, it would seem that a better solution for the perpendicular stress join be combined with the lateral solution, so that the loading be across the lateral not perpendicular join. be interested to know if you have tried this... Oh also as Colin Quilter said, top marks for testing and backing up your options with more than theory.

Samuel, this is brilliant. I'm so tired of videos where someone just talks with nothing to back it up. I hope you keep up your scientific investigations. Take a look at articles on backpacking gear from 20 and 30 years ago. Things aren't better just because we have better materials, they're better because people like you are going back to the simple question: what do you need it to do? and what's the best way to do it? (Most big companies look at what the other big companies are doing and then copy what they like best. After this circle jerk goes around twice what's the result? )

where can i get Elastosil E41 in Canada?

Im looking to glue some rip stop nylon snow skirts fabric to the vestibule of my winter tent any suggestions for what glue? thanks water proof isnt a issue just trying to stop spin drift from coming in

Great vid! Very informative.

Thanks for posting this video. How is gluing compared to sewing when it comes to longevity? Will the glue still have the strength 20 years from now?

much appreciated

Samuel, thank you for your video, it was very helpful. Now I just have to find the product Elastosil E 41, to get on with my project. All the best....B.

This must be where Dutch got the idea 🙃

need a cp, in my country its so difficul to get that glue..

Hi where did you get the E 41 adhesive ??? I can not find any so far ..out of stock is the best

I have no idea of how you glued it. I have glued silnylon with Elastostil E41 and it absolutly have no gluing effect. It easily tears appart. How long did you let it cure?

Now you've had your shelter for a couple of years, how are the glued seams doing? Any issues with degradation?

how does this hold up to packing it down? Does the silicone handle being stuffed in a stuff sack well? I'm thinking about getting some silpoly and making a tarp this way?

What are simension. Do you have some plans for it?

Could benefit from comparing mm^2 of glued surface area to mm^2 stitched surface area. This video is conclusive enough for me, but I'm guessing you wish to keep it as scientific as possible. Anyway: nice one!

Could you provide a video of elastosil e41 application? Have you used this product on other polymers?

was it elastosil 43??

Hey, I noticed you've only made two videos. So you can now go one of three ways. Make a video here and there or just stop altogether. (Guess that's me), two: look at others making videos on subjects that you want to make videos on . Then make videos just like theirs... then you will just be like everybody else (The corporate: Institutional Imperative. Your company does it this way because all the other companies are doing it this way, except at some point the feedback loop was closed.... This is why so much camping, photography, -name a field!- ends up in a rut. How can Z-pack and other tiny little shops pop up making amazing gear that revolutionizes their field?) Or third option: sure learn from others, understand that you are copying stye, steal (Picasso stole but he remained Picasso.) delivery, pacing.... but keep your scientific/engineering angle: People don't understand this, but they can appreciate it when you do it. (You could even miss a step or outright lie and most people wouldn't notice. That's called Marketing. You're interesting in engineering.) Always make the video you'd like to see. Then you'll have fun and really contribute. ah, but here's the rub. Know what happens when you invent something radical and new? Nothing happens. (The iPhone happened because Apple and Jobs already had clout. Then Steve Jobs bullied, shamed and out 'styled' everybody else. ) Thomas Kuhn's the Process of Scientific Revolutions sums it all up brilliantly: the radical new and proven concept is ignored, usually for a generation. I just spent the weekend trying to figure out the best way to seal silnylon, and then I asked the question: Gaiters: What if you stretched neoprene over the boot, kept it as tight as possible up over the ankle, then used a waterproof fabric up to the knee? Could this work? Water deeper then my ankle? I finally found my yard of neoprene-- stretching it over my boot.... Absolutely it should work-not like waders or boots, but... The question became Why hasn't this been done already? (WWI gaiters, very tight. Those guys knew something about gaiters that none of the outdoor gear manufacturers seem to have bothered learning. WWI gaiters were probably not watertight but they were probably pretty close to it. What's the most common feature of modern gaiters? Velcro so you don't have to take your boots off. Instead of making better gaiters, they've been busy making them easier. ) Bottomline? If you continue your approach, even as a hobby, you will come up with ideas and gear that are fresh, exciting, revolutionary....but probably no one will notice. But you won't worry because you'll be having the most fun. [Clearly I'm busy procrastinating from my project, an old guy jabbering, Usually at this point I delete this nonsense, but your video shows a lot of promise. So hopefully my nonsense is encouraging. I think my point is that we can all do things that change the world and you seem to be well on your way.]

What was the weight of the nylon?

"Sew" and and "so" rhyme.

Thankyou for the video. FYI sewing is pronounced sO-ing and sew is sO
