I am trying to plan out two projects here, with minimal experience sewing. I spoke some with the gentleman from ripstopbytheroll.com for some ideas on materials. In all of these aspects i want balance. For instance, an ultralight backpacker might go with a tent that is extremely thin material to save weight, but the tent may get holes more easily and generally wear out faster. I'd like to be somewhere close to the middle when it comes to durability vs ultra super duper hyper light weight. Price vs payoff is also a consideration of balance. Like not spending 5x the money to save 1oz.
In general, what type of thread do you use for this sort of application?
What would be a good source for tough reliable zippers for a cold weather sleeping bag, and water resistant ones you would need for a tent?
I'm not all that familiar with sealing the seams on something that is supposed to be waterproof. I hear taping seams mentioned, but don't exactly know what that means. I've seen waterproofing silicon spray, that seems fairly straight forward. Is the actual type of seam sewn also a component of the waterproofing?
PROJECT 1:
TENT; I want to go with a tent versus tarp because it seems more idiot proof in keeping rain out and spiders/mosquitos off my face.
I am planning to emulate the sea to summit, specialist solo and duo tents in design, which if you are not familiar with them, are extremely light tents that can be supported internally by trekking poles and then only need stakes and guy lines to stand up. The sea to summit is made out of extremely expensive cuben fiber fabric, I'm probably not going to go that expensive of a route, and the cuben fabric is so thin i have heard a lot of reviews mentioning how much easier it gets holes that have to be taped up to prevent more tearing.
To consider what weight fabric is appropriate for lightness, I intend to make the tent roughly a 1.5 person tent, room for one person and gear normally, 2 people side sleeping in an emergency survival situation where comfort is not the primary concern.
I was told silpoly was easier to work with than silnylon, and waterproof enough for the walls and top of a tent and the vestibule. So i was looking at 1.1oz silpoly for the top and sides, and 0.9oz no-seeum netting.
For the bottom of the tent, for durability reasons and waterproofing, it was recommended I go with something like HyperD 300 material. Out of curiosity, I have seen thermal barrier tarps, and thermal fabrics, but I never see tent bottoms being made from it. Is this a possible consideration or no? Is it possible the HyperD 300 might be unnecessary with a cheap simple tyvek ground sheet?
The expensive Sea to summit tents, weigh in at 15oz and 22oz without poles or stakes. Adding 6 titanium stakes and two quality trekking poles is in the area of a pound of extra weight. If I managed to keep my hopefully much more durable and cheaper tent to 3.5lbs total or less, I'd be thrilled.
PROJECT 2:
SLEEPING BAG; I guess my goal is to make a fairly flexible(temperature wise) general purpose sleeping bag that is good for cold weather hiking and camping, and survival situations.
For my taste, down is extremely expensive. Obviously everyone knows down's positives, high warmth to weight ratio, and very compressible. My cold weather sleeping bag at the moment weighs nearly 5lbs and is ENORMOUS, even in a compression sack. However, down and even the special water resistant down, can lose thermal efficiency when wet. For survivability in extreme circumstances and cost, I tend to lean towards synthetic fill, but it would be nice if the synthetic i used would improve on the 5lb and monsterous size.
On the subject of fill, ripstopbytheroll.com sells primaloft gold and climashield apex. I have learned that the primaloft is loose material that must be quilted like down in order to not shift and leave cold spots. Therefore the climashield is probably friendlier for a noobie such as myself to work with, but I was also told that the primaloft compresses better than the climashield. How much of a difference there is, or what compressed size i can expect from either, i have no idea. I was told the primaloft is slightly warmer than the climashield, so theoretically I would need less fill. In the case of the climashield, 4 square yards of 5oz material would be 20oz, which is not too bad.
I am of the mindset that warmer is better, because you can always unzip for warmer weather, but you can never make an inadequate bag warmer in cold weather, while on a trail or in a survival situation. For specifically summer backpacking, I may get a different bag entirely, who knows. My goal is to make the bag adequate down to +10 for survival, and hopefully up to +60 with zippers open. I'm not sure how much fill it takes to achieve +10 survival rating, and how big that sleeping bag would wind up being.
Another consideration is the outer and inner material of the bag. It was suggested i use a slightly water resistant fabric that is still light, like 1.0oz HyperD.
I apologize in advance for this wall of text, hopefully someone has the will power to read through it and help me.
