[. . . ] INSIDE TUNING 2. 50 0 PAGE nary Bow Setup . 27 2 Arrow Tuning and Maintenance Guide INTRODUCTION Successful tuning can only be achieved by using a properly spined arrow shaft. Start with a shaft recommended on Easton's Arrow Shaft Selection Chart, available on the Easton web site at www. eastonarchery. com, in the Easton Target and Bowhunting catalogs, and on the Easton Shaft Selector "Plus" software program. Final verification is achieved during the tuning process. [. . . ] Deburring and chamfering is the final step. What needs to be done varies with the type of shaft (see diagrams to the right). ALUMINUM--Deburr only the inside of the wall just enough to eliminate the sharp edge of the tube. X10, A/C/E, A/C/C and HyperSpeed--Deburr the inner aluminum core tube very lightly using the pointed deburring head on your cutoff tool. Be careful not to remove too much aluminum. EASTON CARBON COMPOSITE AND BEMAN ICS STYLE SHAFTS--(Internal Component System)-- On most models, deburr the inside of the tube just enough to remove the burr. CARBON WITH EXTERNAL COMPONENTS-- These components fit over the outside of the shaft, so chamfering must be done on the outside edges of the shaft (see illustration on left). Lightly chamfer the end of the shaft with 180- or 240-grit sandpaper. Rotate the shaft as you lightly drag the edge of the shaft along the sandpaper. Three complete revolutions will produce a sufficient chamfer. Easton recommends that you test-draw one arrow with all components installed (without adhesive) before cutting and finishing a complete set of arrows to confirm the correct length. Easton Aluminum Shaft Weight Groups Easton aluminum shafts are classified by weight groups. This provides archers and bowhunters a way to choose a shaft model based on performance. The lightest groups provide the highest speed and flattest trajectory. The heavier groups are chosen for durability and hard hitting performance. · UltraLite aluminum ­ . 012" wall thickness · SuperLite aluminum ­ . 013" - . 014" wall thickness · Lite aluminum ­ . 015" - . 016" wall thickness · Standard aluminum ­ . 017" - . 020" wall thickness INSTALLING POINTS AND ALUMINUM INSERTS MATERIALS NEEDED FOR INSTALLATION OF POINTS AND ALUMINUM INSERTS Shaft Construction Easton aluminum shafts, depending on the model line, are produced from super high-strength 7178 or 7075 aluminum alloys. Both alloys are processed to their highest possible strength using Easton's proprietary manufacturing technologies. This ensures that Easton shafts will stay straight even through severe shooting conditions. Easton aluminum shafts are cold drawn many times from an aluminum tube that has been fusion bonded from precision coil stock to achieve a perfectly uniform wall thickness. To ensure the integrity of every shaft, each Easton aluminum shaft goes through an eddy current tester that "looks" through the walls and rejects any shafts that may have flaws or imperfections in the material. Each Easton aluminum shaft of a given size and model is guaranteed to have the same inside diameter to a tolerance of ± 0. 0003". This close tolerance ensures a consistent point or insert fit. The outside diameter is made to ± 0. 0003" tolerance to ensure a uniform spine from shaft to shaft. [. . . ] Various points, inserts, and even added weights are used to modify the weight of the front of the arrow. Because of the differences in archers and types of shooting there is not a perfect F. O. C. To provide a good starting point when constructing a set of arrows or when analyzing an arrow's flight characteristics, it may be helpful to look at the range of F. O. C. s most common for each style of archery. Ranges FITA (Olympic-Style) 3-D Archery Field Archery Hunting 11-16 % 6-12 % 10-15 % 10-15 % F. O. C. [. . . ]
