STEP 6 FULL DRAW, ANCHOR and STRING ALIGNMENT ALIGNMENT
SECTION 16 STEP 6 FULL DRAW, ANCHOR and STRING ALIGNMENT FULL DRAW At full draw, the elbow of the drawing arm should be in line with the shaft of the arrow, the back of the drawing hand flat, three fingers in contact with the string and the bow arm straight with the elbow rotated away from the bowstring. BODY ALIGNMENT The student should be standing upright, with 60% to 70% of their body weight distributed forward on the balls of their feet and 40% to 30% on their heels. From a front view the student should be standing upright and should not be leaning back or forward. It is common for students to lean back, taking the majority of their body weight on their back foot. Their spine should be straight and their head directly over their spine.

TOWARDS a MORE MEDIEVAL ARCHER -Improving Your Recreation of the Middle Ages on the Range
APPENDIX 1: TOWARDS A MORE MEDIEVAL ARCHER -Improving Your Recreation of the Middle Ages on the Range Philologus: What is the chief point in shooting that every man laboureth to come to? Toxophilus: To hit the mark Phi.: How many things are required to make a man evermore hit the mark? Tox.: Two, shooting straight and keeping of length Phi.: How should a man shoot straight, and how should a man keep a length? Tox.: In knowing and having things belonging to shooting; and when they be known and had, in well handling of them; whereof some belong to shooting straight, some to keeping of a length, some commonly to them both, as shall be told severally of them in place convenient. Phi.: Things belonging to shooting, what be they? Tox.: All things be outward; and some be instruments for every sere archer to bring with him, proper for his own use: others be general to every man, as the place and time serveth. Phi.: Which be instruments? Tox.: Bracer, shooting glove, string, bow, and shaft. Phi.: Which be general to all men? Tox.: The weather and the mark; yet the mark is ever under the rule of the weather. Toxophilus, 1544 The most important points to be considered when trying to improve the recreation of medieval archery within an SCA setting may be grouped in a similar way to those described above in Ascham's treatise on the how’s and why’s of shooting (which was structured as a discussion between Philologus, a lover of learning, and Toxophilus, a lover of the bow). -

Shooting the Longbow
Shooting the Longbow Some coaching tips Steve Purkiss (Fox Archers) Equipment Bows Longbows, being made from wood, need to be protected from the elements. Even a “varnished” bow can let in moisture due to marks and scratches from regular use. Polish the bows with a wax polish, Danish Oil or even a smear of vaseline to help keep out the wet which can ruin your bow. Pay special attention to the area where the arrow “passes” the bow as obvious wear will take it down to exposed wood. Also keep the string waxed, most modern strings are fairly waterproof but as the string is twisted and the strands rub against each other under tension waxing helps cut down wear. Apply wax to the string and then rub with a small piece of leather this warms the wax and string and helps the wax to move between the strands. If you are used to shooting a recurve bow then you will find that the draw weight of a longbow feels different to a recurve simply due to the nature of the beast and therefore if you are used to a 30lb recurve you might find a 35lb longbow comfortable. The bracing height of the bow is the distance from the string to the belly of the bow (the part of the bow facing you when you hold it to shoot). This is often written on the bow (normally 5.5” to 6.5”) set your bow up to this height for optimum performance. Always “warm up” your bow before you shoot, this is done by rubbing the bow with a cloth and then repeatedly drawing the bow to half draw and gradually increasing to full draw either in the normal manner of by putting your foot against the grip and holding the string then you can use you foot and hand to extend the bow. -
Topics on Archery Mechanics Joe Tapley
Topics on Archery Mechanics Joe Tapley Topics on Archery Mechanics Introduction The basic physics of archery has in principle been understood for around 80 years. The last topic to be theoretically described was vortex shedding (aerodynamics) in the 1920's related to developments in the aircraft industry. While the principles of archery are understood, in practice the behaviour of the bow/arrow/archer system (termed 'interior ballistics') and the arrow in flight (termed 'exterior ballistics') are somewhat complicated. In order to understand the mechanics of archery computer models are required. Models related to interior ballistics have been developed over the years becoming more realistic (and complex). A few related papers are listed below: Kooi, B.W. 1994. The Design of the Bow. Proc.Kon.Ned.Akad. v. Wetensch , 97(3), 283-309 The design and construction of various bow types is investigated and a mathematical model is used to assess the resulting effects on the (point mass) shot arrow. Kooi, B.W. & Bergman, C.A. 1997. An approach to the study of Ancient Archery using Mathematical Modelling. Antiquity, 71:124-134. Interesting comparison between the characteristics and performance of various historical and current bow designs. Kooi, B.W. & Sparenberg, J. A. 1997. On the Mechanics of the Arrow: Archer's Paradox. Journal of Engineering Mathematics 31(4):285-306 A mathematical model of the behaviour of the arrow when being shot from a bow including the effects of the pressure button and bow torsional rigidity. The string forces applied to the arrow are derived from the bow model referenced above. -

Editorial by Morten Wilmann, Chairman Dear Judges, When writing this editorial we are just up front of the Olympics. For judges on duty for that event, it is starting to be a bit thrilling. Some athletes are saying that this “is only one event like other events”, and some may regard it as such (although I doubt if they manage). In spite of recent news about extensive doping in some sports and in some countries, I still think that the Olympics stands out as a very special event, well regarded and connected with “personal glory” for the winners. Archery in the Olympics 2016 – in Rio de Janeiro, Brazil – takes place in the famous street of the Sanbodromo where the carnival regularly takes place, again a rather iconic place for archery. These are surroundings that may add some thrill to the competition, and your committee is confident that our judges will perform at the same top level as the archers – in spite of the possible stress of the moments.

Discussing Draw Length
Discussing Draw Length The "Perfect" Draw Length Your own "perfect draw length" is the draw length setting at which you are the most comfortable and the most accurate. There is no right and wrong, no absolutes. But it is unlikely that a 5'10" guy will be successful with a 30" draw length, and similarly unlikely that a 6'3" guy will shoot well with a 28" draw length.......not impossible - just unlikely. For some, a "perfect draw length" may be ultimately determined by feel (and some trial and error) rather than by calculation. However, we still recommend a common-sense approach here. If you're new to the sport, you'll have better luck if you just play the averages and choose an initial draw length that's similar to others of your same size and stature. Fortunately, on most bows, making a minor draw length change is pretty simple. So it's not quite a life or death decision to start. However, as you become more immersed in the sport and begin to "fine-tune" your game, you may wish to experiment a little with your draw length. Why Draw Length Matters More Draw Length = More Power The longer your draw length, the longer your bow's power stroke will be - and the faster your bow will shoot. As a general rule, 1" of draw length is worth about 10 fps of arrow velocity. Bows are predominantly IBO Speed* rated at 30" draw length. So if your particular bow has an IBO speed of 300 fps, and you intend to shoot the bow at 27" draw length - you should expect an approximate 30 fps loss in speed. -
Archery Notes
Archery Notes Description: Archery is a sport that involves the use of a bow and a number of arrows. The bow is used to shoot the arrows at targets. We will be shooting at stationary targets. This is referred to as ‘Target Archery’. Equipment: Bow: Length and weight varies with the individual (18-25 lbs. for class use: 20-30 lbs. for club use) The style of the bows vary – straight or recurve in Fiberglass, wood, and metal. Arrows: length according to length of arms of the archer (24-28 “). Wood, fiberglass, aluminum, carbon/alloy composite, and carbon fiber. Targets (butts): circular or square targets made of dense Target Butt or buttress: Material that can sustain the impact of the arrow. Straw, Styrofoam, compressed cardboard. Bow strings: dacron- single or double loop according to the type of bow. The center part of the string is wolven thicker to accommodate the nocking of the arrow. This is referred to as the serving. Rubber finger tabs (rolls) are also attached to the serving. A single roller on the upper section and a double on the lower section. Target Faces: thick paper with concentric circles that vary in colour from the outside in. The target is divided into 5 different coloured sections. Safety tackle: Arm guard for the inside of the bow arm. Quivers: ‘Arrow Holder’. Used to organize and hold arrows for the archer. Stringing the bow: Step through method (push-pull) Instructions 1. Slide the top loop of your bow string over the nock and down the limb about halfway, or as far as the loop will allow. -
