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. FromThe correct a rear postureview the is student the one should on the be left standing with the upright tick. withThis a is stra alsoight known spine. as chest-down technique.

Ideally the body’s centre of balance should be centred in a line below the archer’s spine toward their feet By not standing straight and keeping the spine straight, long term this can cause injuries as well as affect the archer’s development. -
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). -

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. -

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. -

Crossbow Permit Application Instructions
Crossbow Permit Application Instructions The attached application must be completed and signed by the applicant and the applicant’s physician. APPLICANTS PLEASE NOTE: Successful applicants will not receive a hard copy crossbow permit; instead their disability status will show on their license and can also be seen on their customer profile in the MassFishHunt online licensing system. It will read “Disability: Crossbow”. Therefore, all applicants must have a MassFishHunt account for their application to be processed. The crossbow status will remain valid for the lifetime of the applicant unless revoked by the director of the Division of Fisheries and Wildlife. The applicant is required to purchase the appropriate hunting/sporting licenses and stamps each year. It is also important to remember that once you purchase a hunting/sporting license, you must purchase subsequent licenses using the same customer identification number in order to maintain your crossbow status. PHYSICIANS PLEASE NOTE: The law allows individuals with a permanent disability preventing them from using traditional archery equipment to apply for a lifetime permit to hunt with a crossbow. Written certification from a physician attesting to the disability will be part of the application process. The applicant’s disability must be a permanent physical disability and as a result of that permanent physical disability, the person cannot operate a conventional or compound bow. The physician must provide a narrative in terms that a lay person can understand, as to how the permanent disability directly affects the applicant’s ability to operate a conventional or compound bow. If there is any question of the applicant meeting the criteria, the applicant is subject to a review by a medical review board at the expense of the applicant. -

SCARNECCHIA1 AND JASON D. SCHOOLEY2 1. Department of Fish and Wildlife Sciences, University of Idaho, Moscow, Idaho [email protected] 2. Oklahoma Department of Wildlife Conservation, Jenks, Oklahoma In this paper we review the history and development of bowfishing, provide a case study of a high-profile bowfishing tournament in Oklahoma, survey and summarize management of the sport in all 50 states, and provide scientifically-based approaches for its management. Bowfishing has a distinct niche in the evolution of the bow and arrow and in fishing, as one of several methods practiced by many and scattered indigenous cultures worldwide. In the past century, advances in technology, including the development of the compound bow, custom boat and lighting systems for night bowfishing, and improved information transfer have opened the sport to many people previously unable to participate in the sport at a satisfying level. -
