APS (Arrow Preparation System)
APS is made to address all the imperfections and the short comings of today's 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 as standard (optional supports are available for purchase) and each support has 2 high precision ball bearings installed to ensure smooth and accurate arrow assembly. To ensure precision, we custom made the shafts for the ball bearings which each shaft is made of brass and high precision CNC machined, so the ball bearings will be perfectly aligned to the support with no lateral movement. If the ball bearings did wear out, one just needs to replace the ball bearings and the APS will again provide perfect alignment.
As APS has no pre-built grinding surface, one would not have to worry about the wearing of the grinding surface as there is none. Grinding surface is achieved by using common 3M adhesive back sandblaster sand paper (3-2/3” X 7-1/2” sheet is commonly available for less than $3.00 in hardware store). One just sticks the sandblaster on the grinding block and it is done. One can have a fresh grinding surface by just replacing the sandblaster. The grinding block is made from a solid piece of Aluminum and then hard anodized for durability, so there is no worry about the straightness of the block even after repeating sticking and removing sandblaster from the block. 150 grid adhesive back sand paper is recommended for squaring carbon and aluminum shafts/arrows while 220 grid is recommended for inserts. Due to the nature of some aluminum shaft, it is recommended to change the sand paper frequently due to the filling characteristics of aluminum when grinding.
For those who prefer a table/bench mounting system, APS has a built-in center line indicator so it is extremely easy to drill multiple center holes on APS and then to mount APS on a work bench.

APS is made to perform 3 basic capabilities/functions for arrow building and tuning process.
1) Arrow Spinner to check concentricity of the arrow at different stages of arrow building
2) Squaring the Arrow Insert Ends before and after gluing a typical insert
3) Squaring the Arrow End fletched with vanes before nock installation
