However, not all of the potential energy is transferred to the arrow. The efficiency describes the relationship between the kinetic energy of the arrow and the potential energy at full draw. A large number of parameters influence the efficiency. Simplified it can be assumed that 70-80% of the potential energy is transferred to the arrow. The remaining 20-30% remain in the bow as internal energy. This is noticeable, among other things, in the vibrations after the shot.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]Most of the energy transferred to the bow is used to move the limbs.

Internal stresses arise in every metallic raw material during production at the cooling process, because the surface of the raw material cools faster than the inside. These stresses can be reduced by suitable processes, but not completely eliminated. If a component is now milled from the raw part, around 90% of the material is removed in the case of the riser. The internal stresses, which were previously in equilibrium, then cause the component to deform.<br \/>\nHowever, the support points of the limbs must be made exactly parallel so that the bow is straight and the energy is transmitted straight into the arrow.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]Specially stress-relieved 7075 aluminum from a renowned German manufacturer is used.<\/p>\n<p>The riser is manufactured in several tensions. This means that the riser is re-clamped on the CNC machine several times between the production steps. After each production step, the internal stresses are already partially &#8220;discharging&#8221;. In this way, the deformation can be compensated for in the subsequent processing.<\/p>\n<p>If, on the other hand, the riser is milled in one tension, the deformation only occurs after completion and can no longer be compensated.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]The fitting bores for the limb bearings are milled in the last production step.

The groove for the tiller screw or the hole for the dovetail are often not exactly in the center, even though the limb is straight. If, on the other hand, the limb is already twisted, this cannot be compensated for by a static torsion correction in the riser, since the torsion of the limbs changes dynamically when drawing the bow. For this reason, this adjustment option is deliberately avoided and instead attention is paid to the greatest possible parallelism of the bearings.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]The riser offer precise, stepless lateral adjustability of the limb mount on the tiller screw and the bearing.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]<a href=\"https:\/\/www.novaery.de\/en\/recurve-riser\/#FLAT\"><span style=\"color: #aa0000;\">F.L.A.T.<\/span> &#8211; Form Locking Alignment Technology<\/a>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_empty_space woodmart_hide_large=&#8221;0&#8243; woodmart_hide_medium=&#8221;0&#8243; woodmart_hide_small=&#8221;0&#8243; woodmart_hide_extra_small=&#8221;0&#8243;][vc_row_inner css=&#8221;.vc_custom_1635925704982{background-color: rgba(0,0,0,0.2) !important;*background-color: rgb(0,0,0) !important;}&#8221; row_reverse_mobile=&#8221;0&#8243; row_reverse_tablet=&#8221;0&#8243;][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]<\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"20%\">\n<h5>F-02:<\/h5>\n<\/td>\n<td>\n<h5>The surface must be of the highest quality, both visually and haptically.<\/h5>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]The quality and feel of the surface are the first things that athletes notice about a riser, even before the bow is shot. Milling marks such as chatter marks can be visible, which are caused when the milling tool starts to vibrate due to unsuitable process parameters. Surfaces polished by hand are usually never completely uniform and sandblasted surfaces can form a file-like surface structure after anodizing, to which dirt particles adhere. These are visible as a color difference and are difficult to remove, since polishing cloths or similar leave particles on the surface.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]The risers have a high-quality, modern, matt look and a pleasant feel thanks to anodizing processes and pre-treatments specially developed for 7075 aluminum, so that dirt can be removed more easily.[\/vc_column_text][vc_single_image image=&#8221;24204&#8243; img_size=&#8221;full&#8221; onclick=&#8221;link_image&#8221; woodmart_inline=&#8221;no&#8221; parallax_scroll=&#8221;no&#8221; css=&#8221;.vc_custom_1636039047551{border-top-width: 5px !important;border-right-width: 5px !important;border-bottom-width: 5px !important;border-left-width: 5px !important;background-color: #ffffff !important;border-left-color: #000000 !important;border-left-style: solid !important;border-right-color: #000000 !important;border-right-style: solid !important;border-top-color: #000000 !important;border-top-style: solid !important;border-bottom-color: #000000 !important;border-bottom-style: solid !important;}&#8221;][\/vc_column_inner][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]Milling marks are already minimized during production by optimizing the milling programs down to the last detail and finishing the surface very finely.<br \/>\nBefore anodizing, the riser are blasted with a special granulate. The component then goes through an additional step in which the sharp micro-edges created by blasting are rounded. This reduces the adhesion of dirt particles and the result is a matt, satin-like surface.<br \/>\nThe risers are coated with a high-quality hard anodizing process specially developed for 7075, which guarantees maximum durability with the greatest possible smoothness.<br \/>\nIn addition, all edges are deburred with radii directly in the milling process, which leads to unsurpassed repeat accuracy.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_empty_space woodmart_hide_large=&#8221;0&#8243; woodmart_hide_medium=&#8221;0&#8243; woodmart_hide_small=&#8221;0&#8243; woodmart_hide_extra_small=&#8221;0&#8243;][vc_row_inner css=&#8221;.vc_custom_1635925704982{background-color: rgba(0,0,0,0.2) !important;*background-color: rgb(0,0,0) !important;}&#8221; row_reverse_mobile=&#8221;0&#8243; row_reverse_tablet=&#8221;0&#8243;][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]<\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"20%\">\n<h5>F-03:<\/h5>\n<\/td>\n<td>\n<h5>The angle of attack of the limbs should be adjustable in an extended range to allow a greater variance in the tiller and the draw weight.<\/h5>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/4&#8243;][vc_column_text woodmart_color_scheme=&#8221;light&#8221; woodmart_inline=&#8221;no&#8221; text_larger=&#8221;no&#8221;]With conventional risers, the tiller range is limited by the angular error between the tiller screw and the limb.
