 APS (Arrow Preparation System) APS is made to address all the imperfections and the short comings of today arrow preparation tools on the present market. In the past to prepare an arrow for assembly, one usually uses an arrow squaring tool, then another tool to square the other end after the arrow had been fletched, then a spinner to make sure it is concentric by mass. With APS, one can assemble arrows easily and accurately on a single piece of tool. APS is a high precision all-in-one tool to do all the mentioned jobs and it is designed and engineered with hunters’ mind. APS is a unique track base system with 2 supports for the working arrow which each support employs 2 high precision dual ball bearings system to ensure smooth and accurate arrow assembly. To ensure precision, the ball bearing support is made of custom built high precision brass shoulder screws so the ball bearing will be perfectly aligned on the support with no lateral movement. If the ball bearings did wear out, one just needs to replace the ball bearing and the APS will again provide perfect alignment. As the APS has no pre-built grinding surface, one would not have to worry about the wearing of the grinding surface as there is none. Instead grinding surface is achieved by using what is commonly available in the hardware store, like 3M adhesive back sandblaster sand paper (3-2/3” X 7-1/2” sheet is commonly available for less than $3.00) and then just stick the sandblaster on the grinding block and it is done. The grinding block is made of a solid piece of heavy anodized Aluminum for durability, so one would not have to worry about damaging the block while removing the adhesive back and affecting the straightness of the block.

1) Arrow Spinner at different stage of arrow building to check concentricity of the arrow  2) Squaring the Arrow Insert Ends before and after gluing on a typical insert  3) Squaring the Arrow Ends that had been fletched with vanes before nock installation  More accessories for the APS track system is coming in the near future:
