Fire Bow Drill
Making Fire With The Bow Drill When you are first learning bow-drill fire-making, you must make conditions and your bow drill set such that the chance of getting a coal is the greatest. If you do not know the feeling of a coal beginning to be born then you will never be able to master the more difficult scenarios. For this it is best to choose the “easiest woods” and practice using the set in a sheltered location such as a garage or basement, etc. Even if you have never gotten a coal before, it is best to get the wood from the forest yourself. Getting it from a lumber yard is easy but you learn very little. Also, getting wood from natural sources ensures you do not accidentally get pressure-treated wood which, when caused to smoulder, is highly toxic. Here are some good woods for learning with (and good for actual survival use too): ► Eastern White Cedar ► Staghorn Sumac ► Most Willows ► Balsam Fir ► Aspens and Poplars ► Basswood ► Spruces There are many more. These are centered more on the northeastern forest communities of North America. A good tree identification book will help you determine potential fire-making woods. Also, make it a common practice to feel and carve different woods when you are in the bush. A good way to get good wood for learning on is to find a recently fallen branch or trunk that is relatively straight and of about wrist thickness or bigger. Cut it with a saw. It is best if the wood has recently fallen off the tree. -

History Lesson -- a Look at How Construction Tools Have Evolved
TOOLSCool R A Look at How Construction Tools Have Evolved By Steven Ferry As you purchase, use, repair or swear at the tools used on the job, you probably don’t give a second thought to how far we have come in our ability to swiftly and safe- ly erect and finish ever larger, taller and more durable homes, offices, factories and other buildings in the United States. In 400 years, we have moved from the crude grass and hide structures of the first settlers to timber, brick, con- crete, steel, glass and now plastic material-in the process freeing the builder from the need to also man- ufacture or find the building materials. We can create whatever climate we want indoors while remaining impervious to the one outside. Design tools have moved from ideas in the builder’s head, and the occasional sketch, to computers. Code officials, architects and consultants in everything from construction management to quality control have made building into a series and sequence of high- ly specialized activities that together bring about the fabulously efficient constructions of today—efficient in terms of outlay of effort in the construction and running of the buildings. Pivotal to all the successes in construction are the tools we use to accomplish the work on the job site. If Henry David Thoreau Published by AWCI 97 had thought back to the time he spent then finished with an “adz,” an ax building his cabin in the woods, he shaped like a hoe. The adz-man either might not have insisted that men had stood or sat on the timber and cut become the tools of their tools. -

A visual emphasis on beams, purlins and connections lends character and a powerful aesthetic sense Construction of strength. Historically a handcrafted skill of mortise and tenon joinery, heavy timber construction has been modernized by tools such as CNC machines, high- strength engineered wood products, and mass-production techniques. A growing environmental awareness that recognizes wood as the only renewable and sustainable structural building material is also invigorating this type of construction. Heavy timbers are differentiated from dimensional lumber by having minimum dimensions required by the building code. Modern versions include sawn stress-grade lumber, timber tongue and groove decking, glued-laminated timber (glulam), parallel strand lumber (PSL), laminated veneer lumber (LVL) and cross laminated timber (CLT). Structural laminated products can be used as solid walls, floors and columns to construct an entire building. Modern heavy timber construction contributes to the appeal, comfort, structural durability and longevity of schools, churches, large-span recreation centers, mid-rise/multi-family housing and supermarkets, among many other buildings. -
Learning the Hand-Drill Method of Fire-By-Friction
Learning the Hand-Drill Method for Fire-by-Friction by Kato Haws Friction fires are not very practical, but they can be fun. The hand-drill method is less technical than the bow-drill method. You can learn to do it. The following are some ideas of how to proceed: Cut a 3/8” dry horseweed stalk about 24” long for your spindle, and check to see if it is straight. (Horseweed is very wide spread. See Wikipedia for pictures of horseweed). If necessary straighten the spindle using a heat source. Heat it, bend it, remove it from the heat source, and hold it straight as it cools. It is important to have a straight spindle. It is possible to find horseweed stalks that are straight, it just takes more looking. Cut or split a baseboard of white cedar fencing (no hole cedar) from the lumberyard about 11” long and 3/8” thick. I personally mark the board with a straight edge and a pencil and then cut it with a saber saw, but many methods can be used. A table saw would be ideal if you have one and know how to use it properly. Using a knife make a 3/8” dimple about an inch from the end of the baseboard. Spin the spindle in the dimple to seat it in. You don’t have to get actual smoke at this point. The main thing is to make sure exactly the spindle wants to spin before proceeding. Cut an inverted “V” from the edge of the baseboard toward the center of the dimple. -

firecraft what is it? It's starting and managing fire, which requires fuel, oxygen and ignition. The more natural methods usually progress from a spark to an ember to a flame in fine, dry material (tinder), to small, thin pieces of wood (kindling) and then to firewood. Early humans collected embers from forest fires, lightning strikes and even volcanic activity. Archaeological evidence puts the first use of fire between 200-400,000 years ago – a time that corresponds to a change in human physique consistent with food being cooked - e.g. smaller stomachs and jaws. The first evidence of people starting fires is from around 10,000 years ago. Here are some ways to start a fire. Friction: rubbing things together to create friction Sitting around a fire has been a relaxing, that generates heat and produces embers.

Mechanical Performance of Mortise and Tenon Joints Pre-Reinforced With

J Wood Sci (2019) 65:38 https://doi.org/10.1186/s10086-019-1816-2 Journal of Wood Science ORIGINAL ARTICLE Open Access Mechanical performance of mortise and tenon joints pre-reinforced with slot-in bamboo scrimber plates Guofang Wu1,2, Meng Gong3, Yingchun Gong1,2, Haiqing Ren1,2 and Yong Zhong1,2* Abstract This study was aimed at examining the mechanical performance of mortise and tenon joints reinforced with slot-in bamboo scrimber plates. 27 full-scale specimens were manufactured with engineered wood and bamboo products using computer numerically controlled (CNC) technology, then they were tested under monotonic loading. The initial stifness and moment carrying capacity of joints with diferent reinforcing confgurations were obtained from the established moment–rotational angle relationships. It was found that the initial stifness of the reinforced mortise and tenon joints increased by 11.4 to 91.8% and the moment carrying capacity increased by 13.5 to 41.7%, respectively. The total width and grain orientation of the reinforcing plates had signifcant infuence on the mechanical perfor- mance of the mortise and tenon joints. Fastening the plates to tenon with dowels was benefcial to the mechanical performance of the joints. The embedment length and adhesive type had no signifcant infuence to the structural performance of the joints. This study demonstrated the feasibility of pre-reinforcing mortise and tenon joints in new timber construction, and could assist to promote the application of mortise and tenon joints in modern timber structures.
