Scientists ask questions, and then seek the answers. Time and budget are always a constraint. One cannot ask all possible questions, and one cannot seek all possible answers. Some questions require data that provides a high level confidence, while lower quality data is acceptable for other questions. Technology is even more focused. Good technology must meet the criteria of: faster, better, & cheaper.
In 1999, I asked the question, "How did the fishermen on the banks stay warm" The bulk of the answer is that they (or their knitter) used DPN and knitting sheaths to knit substantially weatherproof woolen fabrics. These fabrics were used in single and multiple layers with woven wool and other woven fabrics. However, the real magic was in hand knit fabrics with stitch patterns that increased the warmth of the fabric. The question is as much technology as science. I understood this by early 2007, see
http://gansey.blogspot.com/2007/03/real-ganseys-are-real-warm.html Work since then is just refining the technology, as in:
An inexpensive, but very functional knitting sheath
designed to be tucked into an elastic pant waist
And it is not like we are starting from scratch. We have a lot of information about ships, climate, fishing, physiology, textile performance, textile industry economics and so forth. It is more like we have a "blue print" of an industrial machine and the blue print has some holes in it. We need to go back and reverse engineer the missing parts so everything works together.
I have documented that such fabrics are weatherproof (i.e., will support a pool of water on them for an extended period of time.) I have worn these garments skiing, sailing, climbing, mountaineering, and working in freezing rain. Such garments are exceptionally warm even when compared with the best from modern sporting goods companies such as Columbia, Patagonia, Marmot, and LL Bean. If the skeptic does not believe, then the proper thing to do is say, " I want to test those garments." Yes, we can make arrangements for that. We can even set up a little workshop where we knit while sailing. (An advanced skill, as most people get sea sick. A good part of the skill is to watch the horizon, rather than your knitting.)
I knit such fabrics with DPN and knitting sheaths. There is no question that the process is technically and ergonomically feasible. This is well documented in the literature. There is no need to post data on a topic that is well documented. (I had to get up an experience curve to understand the technology, and I collected data as I climbed that curve. Having data does not make that data new or useful.)
The process is slower than knitting looser fabrics, and thus the fabrics are more expensive. However, even today, warmer garments tend to be more expensive, and thus tight knitting economically feasible.
I have documented on this blog, fabrics can be easily produced with a knitting sheath and DPN. For example I knit a good gansey in 10 days, and I am a fat old man with palsy. If the skeptic does not believe that I knit that fast, then we can arrange to sit down together for a knitting session. The skeptic can touch and feel the produced fabric at the same time. I will even let the skeptic stare at a pool of water sitting on a swatch of fabric. The skeptic can put on a gansey, lie on the floor, and I will pour water on the gansey, and she can note that she stays dry. We can do the knitting workshop in a campground near some very cold river and the skeptic can spend the day in the cold river while wearing the gansey (15 minutes with gansey on/ 15 minutes with gansey off). (If we pick a good cold river or a bathtub full of ice cubes, that activity will last about 17 minutes.)
Such weatherproof fabrics are difficult to produce in large quantity with SPN or circular needles because these do not provide the required leverage for packing the yarns together. Certainly a gansey or two can be done on circs, but if you have 8 brothers and need to produce 9 ganseys (dad) per year, your wrists will get sore. Again the ergonomics were established in the 1930s, so there is really no need for me to dwell on that.
What is left is technical issues of what kind of needles are best and what shapes of knitting sheaths work for different kinds of knitting. There is less of this in the literature. I mean, we have lots of shapes of knitting sheaths, but we do not know if they were different shapes with the same use or different shapes with different uses. The truth is different shapes for different uses. There were at least 11 different knitting techniques that used a knitting sheath. This is a part of what I talk about in class, and if you want to know more - take the class. I have shared photographs of the knitting sheaths and needles that worked, and have written of ones that did not work. I have provided enough data that anybody with even a passing interest can try the process without a large investment in time or effort. Anybody with any interest can knit their own swatches and in 4 hours, be pouring water on their own swatches and timing how long it takes for the water to drain through. The way to test another knitting technique is to try it! You do not go looking for peer review articles on Russian Knitting, you sit down and try it, to see if it works for you!
I certainly have notebooks of data that I have not shared. Every good researcher does. (The only exception that I can think of in an EPA directed Human Health Risk Assessment.) However, I am not going to transcribe the data just because somebody wants to look at it. If they have a specific question, they can ask the question. If they just want to fish, I have given enough information that they can knit their own outfit(s) and go fish. I have a great pile of Shetland to spin.
People come to me saying that they are a researcher, and thus that I should give them my data, but they are not bringing me any data. They are what Al Dring calls, "Sponges". A researcher can find all of the above references. If they do not have the library skills to find the references, then they are lying about being a researcher. On the other hand, there are many people out there with good information, and they share it. I am so grateful to those people. If the helpful people need help finding a particular source, I will help.
I am perfectly willing to answer honest questions. However, I do not tolerate dishonest questions. And, when someone asks a question, I am as likely to show them how to find the answer themselves, as I am to just tell them the answer.
