    I did find it funny that several conservatives I know are simultaneously posting Christmas displays saying "Let's Go Brandon!" and saying "you know, it just doesn't feel like Christmas to me this year for some reason." Spending your Christmas vacation saying "fuck you" will do that.

    I have nothing to contribute to this discussion from a technical standpoint. But I want to comment that it's absolutely amazing to see folks with decades of experience in this sort of thing freely contributing and sharing to help the 'new guy' get it right. This is basically 'doctorate level' harness design and construction stuff. Both theory and practical. Way, way, waaaaaaay beyond my skill/experience. But the fact that Jerry, Lee & Rob are willing to help at the level they are is REALLY cool.

    The historical context is irrelevant. We have Harris because that was required to unseat Trump. All things Presidential are now viewed in terms of Before Trump and After Trump.

    Yes, I still remember when all the anti-vaxxers were the yoga-practicing, granola-eating treehuggers like you find here in Boulder. I even watched a documentary just a few years ago about disease and one the intertwined stories was a classic mother just like that. (Wish I could remember the name). Back then the anti-vaxxers were at the opposite end of the political spectrum from now. And this was from the S1E2 episode of "House" in 2004:

    I have noticed an improvement of the overall tone here in the past two weeks or so. Maybe it's the season?

    Yes, this is a very weird thing. Anti-vaxxers in my lifetime have not been the sort of people who are now refusing. These are very entitled people who have decided that even the very small risk of a vaccine is not for them or their children no matter what the potential cost to society of waning herd immunity. The current movement is made up mostly of people who have all their other shots, they have just been convinced that their is some conspiracy or another at play now.

    Where was the outrage when they started the anti-vaxx movement. https://www.rollingstone.com/culture/culture-features/celebrities-anti-vaxxers-jessica-biel-847779/ Please don't get me wrong - I am pro any vaccine that protects the rest of society.

    It's hard to tell from the above picture but I might consider running the horizontal/leg strap through the center of the mlw as opposed to running the mlw through the center of the leg strap. In theory ether would work but in practice I've seen the two outer layers of the leg peal outwards and down breaking the stiches one by one. By putting the leg on the inside with the tension on the upper mlw I think you force the stitching on ether side into shear. I didn't do this on my rigs because I had stagger in them and I wanted to wrap the leg around the mlw in case it failed. This added redundancy but it did not make it stronger. It made it weaker. If you are going with a continuous leg strap like this I would samwich the leg inside the mlw. You might even think about spreading the leg strap in a v from the hardware to the back pad. Gives you a bit more room for sticking in that joint and makes for a thinner transition at the end of the over lap which is generally to the good in the strength of a junction. Don't be afraid to sew half an inch above and bellow the leg strap but glue that section. Glue helps to stiffen the webbing and makes it easier to sew the ends of the four point with less shrinkage and stress at those points. Don't run the tension higher then you need to to get a good centered stich in the thickest hardest part of the joint. I don't know what's happening up inside your back pad but I'd put a U'd three point by your leg hard wear. On a separate matter. Looking at weight of webbing and weaves and dissimilar webbing vs thread in stich patterns. Interesting things I've seen. Been doing a lot of work with heavy kevlar webbing. Stuff in the 20,000+ range. Kevlar does not stretch very much. There are interesting things that happen with elastic coeff icents and stich patterns. There is something to be said for the ability to stretch and sort of distribute the load across the junction. To maximize the strength you have to have the ability for something to give whether it's in the weave, the thread or the material itself to allow all the stitches to share the load. And it won't be even but I mean as close as you can. Some day I want to do a more organized study but there are relationships between stitch density thread strength thread elasticity length of joint and elasticity of the webbing. We've done some destructive testing of our risers line attachments etc. The kevlar has has allowed/ required us to go to some rather long stitch patterns to get the strengths we need. It's interesting to see how the patterns break. The kevlar is so stiff that we can break just a few stitches at a time pulling it in the hydroloc tester. I think nylon would just go kapow like a rubber band. As an example were ever possible we have been going with a heavy Tec 500 nylon cord rather then a stronger kevlar in our patterns because that little bit of stretch allows for the load to be better shared across those long joints. I don't think I could use that long of a joint with nylon webbing. I think the stretch of the webbing would mean that only part of the joint would be loaded and you would fail the first part of the stitch pattern before the rest. But with the heavy kevlar and the nylon thread we just kept going longer and the failure point just kept going up. It's been interesting trying to get the most out of these materials. Lee

    You got me, but I can say that if you'd tighten your laterals you wouldn't look to be struggling with a perfect student in your avatar.

    "Walk through this Xray scanner if you want to fly. Don't want to get scanned? You can't fly. Even if you think that Xrays are dangerous." Because people voluntarily do what's best for other people? Really?

    Hi Rob, Re: 90 degrees is not the perfect angle for upper leg straps (ULS) to meet the main lift web (MLW) and lower leg strap (LLS). I agree. Here is a photo from Paraphernalia's/Softie website: IMO this is a nicely splayed webbing at the hip joint. I'm not sure why Quag wants to do it like this; I'm sure he has his reasons: Jerry Baumchen
