Standard AeroRest in 3MIL AL Oxide and Camo Finish

Micro Adjustable AeroRest in standard "C" and "U" frame in 3MIL AL oxide Finish

2013 AeroRest Improvements:
    Although 2012 AeroRest is having the highest tolerance, encompassing no less than 3 US patents, using the highest grade material and incorporating totally new design, Firenock discovered that 2012 AeroRest is not perfect for all users.  After selling 2012 AeroRest on the market, Firenock learned a lot about how an arrow rest is supposed to respond on different bows and in the hands of archers with very different shooting styles.  The issues of 2012 AeroRest discovered are as follows:

  1. The containment cup machine tolerance is too tight for normal everyday use: Under temperature over 98F°, the balls start to stick as the 5.98 mm hole begins to expand and the balls starts to jam right inside the cup after each shot.  This issue is further exaggerated due to heat generated via friction when an arrow was shot.
  2. The nylon ball is not precision enough.  The nylon ball's tolerance is 6.0 +/-0.02mm which make some of the smaller balls able to pop out the containment cup while shooting.
  3. The aluminum oxide on aluminum oxide is not ideal for fine tuning adjustment as it can bind.  Example, the pin adjustment head may strip when excessive force is applied to turn the spring adjustment.
  4. Many customers encounter a high tear while paper tuning when set up the bow.  This was discovered due to 3 main reasons:
    1. Some bow designs put out a large amount of down pressure when shot.
    2. Some bowhunters prefer a higher hand position than is considered ideal.
    3. Some archers prefer a much heavier arrow than the original AeroRest spring was designed to handle.
  5. Many customers have an issue gluing the side bar perfectly to the C-frame for the standard rest.  Therefore, all standard AeroRests now come with the side bar permanently pre-glued to the C-frame to avoid this issue.
  6. For the micro-adjust AeroRest, we have listened to our customers and changed the side mounting bar secure system to a compression square fit system.  A specially sourced high pressure torx screw is used instead of a brass nut to secure the side bar to the frame.  This absolutely guarantees that the side bar will not move in any way or form.  The previous version, although flexible, can get loose after a few tournaments or hunt.
  7. The side bar of the micro adjust AeroRest is shortened by 5mm so it will now fit the thinner risers like the PSE Money Maker or most of the Hoyt bows that use TAC risers.
  8. A lower drop side bow mount is available as an option to address issues with bows that need to be tuned with a lower position of the arrow rest.  With the new lower bow mounting bracket, the rest can be adjusted to 9mm lower than our standard AeroRest bow mount.

    To address these issues we have made some changes to the 2013 AeroRest.  We also have not forgotten about our loyal customers who already own an AeroRest.  Therefore, an upgrade kit is now available for those who already own an AeroRest and want to set it up on a new bow easier.  This upgrade kit will be available for anyone who owns an AeroRest for the cost of shipping and handling alone.  If you already own a 2012 AeroRest, you only need to show ownership by sending us a picture of it alone together with the upgrade fee.  If you have purchased from us directly, all you need do is send in the $5.00 shippiong and handling fee, as we should already have all the information.  This upgrade is going to cost only $5.00 and has been available since 1st January 2013.  A step by step video to show how to upgrade is on YouTube.com since.  For those who want this upgrade kit, please send payment via check or money order to AeroRest Update 2013, 511 Robert Street, Henry IL 61537.  A 16 page 2013 Firenock catalog and price list is also included with the shipping.  The upgrade kit includes:
  1. 3 lower tolerance containment cups, it is now 5.95 mm instead of 5.98 mm to make it less critical:  It is also upgraded from 6061-T6 to 7075-T5 so it is less prompt to temperature variance.  It is also harder and lighter.
  2. 3 brass pins with O-rings: To replace the center hard anodized aluminum pin so the possibility of binding can be minimized.
  3. 3 higher pressure springs: with a higher pressure spring to compensate for the heavy down pressure some bows or archery gives.

 

AeroRest Advantages

  1. RICTIONLESS BALL BEARING OPERATION:
    Hard ceramic bearing surface eliminates almost all friction between the ceramic bearings and the arrow.
  2. FULL CONTAINMENT SHOOTING FLEXIBILITY:
    Three evenly spaced “Fingers” hold the arrow in place providing the most stable containment system available today.
  3. NO WEAR CERAMIC BALL BEARING CONTACT SURFACE:
    Industrial grade ABEC#5 ceramic ball bearings hold the arrow in place and due to their hardness meaning virtually no wear.
  4. QUIET DESIGN:
    The “magic” of the AeroRest is each of the three fingers contains 2 ceramic ball bearings and a beryllium copper spring which provides smooth and quiet operation.  For those who prefer ultra quiet, 2 nylon balls are included to be exchanged with the ceramic balls.
  5. 1.5 OUNCE WEIGHT (SUPER LITE):
    The AeroRest is believed to be the most advanced and lightest arrow rest on the market.  This is attributed to the utilization of a new generation of materials (Si3N4 ceramic, MIL-A-8625 Type III aluminum, GR2 Titanium and Beryllium copper)
  6. ULTRA HARD TYPE III ANODIZED FINISH:
    Type III aluminum anodizing finish is applied to the AeroRest with no less than 3 MIL of aluminum oxide for an extremely durable surface.  This gives the rest a natural camo gun grey / olive green finish.
  7. GR2 TITANIUM FASTENERS/SPACERS (NO RUST):
    The GR2 Titanium Torx Fasteners and spacers are 75% lighter than comparable steel components.  Titanium eliminates metal rust issues while providing a precise washer thickness for stacking and maximum torque capabilities for torx screws.
  8. FITS MOST EVERY ARROW SIZE (INCLUDING nano):
    AeroRest can accommodate arrow shaft sizes as small as 0.25” with the enclosed 18 titanium spacers and shafts as small as 0.156” with the optional spacer pack.  The AeroRest can hold larger arrows with shaft sizes up to 0.45” with one retention finger removed.
  9. RELIABLE MOUNTING POSITION:
    AeroRest side bar is permanently glued to the best position on the C frame on the standard position which is base on the cock feather down position.
  10. FOR LEFT OR RIGHT HAND SHOOTERS:
    AeroRest has a mirror image design which allow the rest to be used by right or left handed shooters.
  11. MICRO ADJUSTABLE DESIGN FOR TARGET OR HUNTING:
    Micro adjustable containment spring tension allows the AeroRest to be at home on the target range as well as in the field hunting.

Standard version: $89.95 (camo option)
Micro Adjust version: $174.95 (U Frame option)
Optional Titanium Spacer Pack: $9.95

AeroRest Technical Tour
    AeroRest provides the security of a full containment rest while enabling the arrow to have a maximum of three points contacting the rest.  The magic of AeroRest lies within each finger which contains two ceramic ball bearings and a beryllium copper mini spring.
    AeroRest utilizes two differently sized ceramic ball bearings and a tension spring in each finger to allow for micro tension adjustment between the fingers and the arrow.  The tension is micro adjustable via the slot at the end of the spring tension plug and a flat head screw driver.
    The use of high spec ABEC#5 ceramic ball bearings ensures smooth shooting by providing a super hard and low friction surface for the arrow to rest upon.  The total arrow contact with the ceramic ball bearings is designed not to exceed +0.000,0/-0.000,2 inches which translates to 0.000,000,4 square inches per ball bearing.  Furthermore, due to the hardness and light weight of the Si3N4 or ZiO2 ceramic ball bearings the greatest possible friction surface area between the three ball bearings and the arrow will be the tangent of the ceramic balls and the lips of their hard anodized aluminum cup retainers.
    To ensure the smooth operation of the ball bearings and the durability of the system, the cup retainers are Type/Level 3 hard anodized MIL-A-8625 aluminum, which means their surface hardness is similar to ceramics.
    The AeroRest design specifications described above maximize friction reduction between an arrow and the AeroRest.

The Magic of the AeroRest Summarized
  1. When the arrow is shot only two of three possible contact points are formed between the arrow and the AeroRest.
  2. To further reduce friction the ceramic ball bearings holding the arrow roll forward as the arrow advances at high speed.
  3. The only friction generated from the system is from the ceramic ball bearing and the edge of the anodized aluminum cup retainer which is simply close to zero. This zero friction causes zero wear to the arrow and the system.
  4. Maximum durability and ultra light weight is achieved by utilizing GR2 Titanium fasteners and spacers on the AeroRest (the only fastener that is not Titanium is the set screw that anchors the bow inside the bow holder, it is made of stainless steel).  Case in point, a normal 5/16-40 3/4” blue steel hex bolt weighs in at 0.20-0.22 ounces and a 5/16-40 3/4” Titanium Torx bolt weighs in at only 0.053 ounces. A near 75% weight reduction is realized for that bolt alone.

A "HOW TO" guide to tune AeroRest for a forgiving bullet holes
Mount the Aero-Rest to your bow.  Mount the rest as far back towards your nock as clearance allows.  Make sure the rest is level with the riser.  Using a flat tip Jeweler's screwdriver, tighten the spring tensioners completely tight so there is no play in the ceramic ball bearings.  Start to shoot through paper at a distance of 6-10 feet.  Adjust the rest accordingly to get the tear down to a single hole with no or very little tear.  If you do have a tear, make sure it is exactly at 12 o'clock.  Once you have achieved the bullet hole, or a slight 12 o'clock tear, start to loosen the spring tension screws with the Jeweler's screwdriver.  Loosen these one half turn at a time and shoot until you have a tear at exactly the 6 o'clock position.  Turn the spring tension screws back up one half turn.  Now the rest is set to be the most forgiving it can be while still producing a bullet hole through paper.
