  • Tuning 4 Barebow
    Page 1 Tuning T4T Copyright 1993 for T4BB Copyright 2018 All Rights Reserved By Rick Barebow Stonebraker https://texasarchery.org/resources/39-tunning 6/19/2018 Page 2 FOREWORD This manual is a guide to basic barebow tuning and only addresses the most common styles to help archers get started tuning their bows and arrows. You should adapt the techniques described in this manual to your chosen style. More complex matters are left to the reader's experimentation. Barebow tuning is not as straight-forward as recurve tuning due to the many different styles of barebow archery. There are significant differences in where a barebow archer anchors and where they place their fingers on the string. These differences separate Face Walkers from String Walkers and from Traditional archers. Underlined terms are explained in the Glossary on page 15. See Appendix on page 16 for various styles and advantages/disadvantages. An important part of archery is the equipment. The skill of the archer is also important but if the bow is not properly tuned, the archer's skill is obscured. Tuning may be achieved in a short period but in most cases, will take longer. The archer that puts the most time and effort into equipment will have the most success, which will be time well spent. There are several steps to tuning a recurve style barebow. Always set the brace height as specified by the manufacturer before you set t h e nock- point. Changing the brace height will affect the proper nock point, which is the starting point of tuning a bow.

Soar On Arrow Construction William Moltzan Archery DIY: Making Your Own Strength Trainer Steve Ruis A Proposed Structure for the Mental Game of Archery Simon Needham/Steve Ruis Getting to 650: Conclusion AER Getting Serious: Is It Your Fault? New from Watching Arrows Fly! A New Book from Acclaimed Archery Historian Hugh D.H. Soar! The bow and arrow were invented at least 60,000 to 70,000 years ago and for 99% of that time children learned archery the same way they learned everything else: by doing. At first a child probably played at archery using a found bent stick. Later, they might have been given a purpose –built youth bow (short in length with a weak draw pull) made from basic materials or from a broken adult bow, cut down. Arrows were probably also “hand me downs” and if a child showed enough promise with the bow and arrow, they might be invited to join the hunter’s circle and begin the arduous task of working their way up from the least desirable tasks. More recently, though, children began receiving instruction in the way of the bow. Eminent archery historian Hugh Soar shares his vast knowledge of how youths were taught during this period, both then and now, starting in his native England, expanding to the rest of the U.K, then out to Europe and the U.S., and also including the Middle East, Africa, and the Far East.

  • String Making
    STRING MAKING Introduction Bow strings are probably the easiest thing that can be manufactured or customised for a bow. The most commonly used string is the continuous loop that most people are using for recurve and compound bows. There are other types, one of which is called "Flemish Twist" (usually used on traditional longbows, and for now that's where we will leave it) We will only concentrate on the former. Following are a few things that you will need to get started: 1. String Material The type of bowstring material that you use is entirely up to you. But please make sure that your bow is designed to take the bow string that you are about to use. Most older bows with wood or wood/glass limbs are not designed to take the performance strings such as Fast Flight, BCY 450, etc and Dacron is the preferred choice for these older or lightly constructed recurve bows. Dacron is also used for compound bows where the cables are still made of steel. Kevlar although well known as a bow string material is generally no longer in use and is not now recommended. Fast Flight and it's equivalents are a must for today's high performing recurve bows and for the string and cable systems of nearly all compound bows. Besides getting your preferred bow string material, It is strongly recommend to get some Dacron string material for practice purposes. Dacron strings are relatively cheap compared to other string materials and can be used to make your first practice strings.

  • Applications of Physics to Archery
    Applications of Physics to Archery H. O. Meyer Physics Department, Indiana University [email protected] (6 November 2015) . Abstract: Archery lends itself to scientific analysis. In this paper we discuss physics laws that relate to the mechanics of bow and arrow, to the shooting process and to the flight of the arrow. In parallel, we describe experiments that address these laws. The detailed results of these measurements, performed with a specific bow and arrow, provide insight into many aspects of archery and illustrate the importance of quantitative information in the scientific process. Most of the proposed experiments use only modest tools and can be carried out by archers with their own equipment. 1 INTRODUCTION For more than 10,000 years, human civilizations relied on bow and arrow to provide food and to fight wars. As gunpowder gradually displaced human-powered weapons, archery declined until the 18th century when it experienced a revival as a recreational activity and as a modern sport. The behavior of bows and arrows, the shooting process, and the flight of the arrow towards the target are described and explained to a large extent by physics, mainly mechanics, elasticity and aerodynamics. Recognizing this, bowmen with scientific knowledge began to perform quantitative experiments with their bows around 1920 [1,2]. An anthology of early scientific archery papers was published as a book in 1947 [3]. Insight gained from these studies questioned the traditional longbow design and transformed bow making from a craft to a science. The continuing advancement of archery equipment, based on scientific principles, has resulted in the modern Olympic recurve bow and in the compound bow, which uses a system of cables and pulleys to modify the draw force.
