Firenock:Arrow Preparation System (APS)

APS (Arrow Preparation System)
    Firenock designed APS to resolve the imperfections and shortcomings of the various current arrow preparation tools on the market.  Today, in order to consistently build reliable arrow shafts, there are several preparation procedures that one must complete before continuing to installation and assembly.  Usually, these preparations procedures include the use of several difference tools at different times -- a squaring tool for both sides of the arrow before and after fletching or a spinner to make sure your shaft is concentric, for example.  With the Arrow Preparation System or APS, arrow shafts can be preparative in a both time efficient and space efficient manner. A 6-in-1 tool (nock end squaring tool, insert end squaring tool, fletched nock end squaring tool, broad-head/field point spin checker, outsert concentricity checker, and general spin checker), APS is truly engineered with our customers in mind.  We believe that, once you try APS, you will discover how essential a tool it is for precision arrow building.

Special Features of the APS
    Adjustable Roller Track Base System: To guarantee that the APS can be used to square any length arrow or type of fletching, a unique track base system was developed.  Involving two to three rollers, the system allows the user to change their position by simply loosening their lock screws, moving left or right, and locking again.
    Never Wear Grinding Surface: Made of a solid piece of aluminum that is hand-anodized for durability, the APS grinding block is different from any other arrow preparation tool because of its longevity.  Recommended with the use of common 3M adhesive back sand paper (3-2/3 X 7-1/2), APS's grinding surface is interchangeable.  If the sand paper worn out, just replace it and you have a fresh grinding surface again.  APS 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 sticking and removing sand paper from the block repeatedly.
    Crowned Ball Bearing: APS roller is equipped with crowned ball bearing which this unique ball bearing is initially used on PAPS (Professional Arrow Preparation System).  This crowned ball bearings provide large surface to support the arrow and to allow smooth operation even under high pressure.  The large size crowned ball bearing also eliminate lateral movement of arrow especially while doing squaring.  The crowned ball bearings is sealed for durability and it is pre-fitted with mounting screws to give more rigid support and to eliminate play.


  1. For those who wish to mount your APS to your work bench or table, the track base has an easily identifiable center line marking for your convenience.
  2. We recommend 150 grid or higher adhesive back sand paper is recommended for squaring carbon and 220 grid adhesive back sand paper for inserts and/or aluminum/carbon mix shafts/arrows.  * Due to the filing nature of some aluminum shafts, it is recommended to change the sand paper frequently.
