Bow Tuning – Basic Setup continued

IMG_7304Now that your bow is together we need to make sure the arrow rest is installed correctly, install a nocking point and adjust the center-shot. It is my recommendation to always install the arrow rest before installing your nocking point. So, let’s start with the arrow rest.

Installing the Arrow Rest

There are a lot of types or arrows rests available on the market. Check out my earlier blog about the various types of arrow rests. For this blog, I will be focusing on the most commonly used one for Olympics style bows, the pressure/plunger rest.

The main purpose of the arrow rest is to hold the arrow in place until the arrow is shot. A  plunger style arrow rest is designed with a support arm just long enough to hold the arrow, with a slight inward angle to the bow, and it moves out of the way with the shot.  They should also be adjusted so that the support arm does not protrude beyond the outside of the arrow. This is to minimize contact with the arrow and minimize impact on the arrow flight. Lastly the arrow rest must be positioned so the plunger/pressure button is square to the center of the arrow.

Olympic recurve bows come with a threaded hole for the plunger/pressure button and the arrow rest typically is installed and centered over the hole as the arrow rest and plunger work in conjunction with each other. Note, some risers have two holes and you should use the back one as a starting point which should be directly over the riser’s pivot point.

Pivot Point: The deepest part of the riser handle.

Alternatively, if your bow did not come with a threaded hole or you are using a traditional bow the arrow rest should be installed at the contact point of the arrow onto the rest directly above the “pivot point” of the bow. You may also want to investigate other types of arrow rests to match your style of bow.

Nock Pointing

Although some recurve archers use a tie-on nocking point, I recommend starting with a simple clamp-on type nock. Clamp-on style nocks are fairly easy to install and simply require your bow square and nocking pliers.

Nocking point: The location you attach your nock, it is usually measured 5mm (1/4”) above square from the center of the plunger and arrow rest.

If your arrows are loose on your string, you can consider adding a nock serving for a better fit however once the nock is installed you can begin shooting.

Center-shot and the Plunger

For an Olympic archer the plunger (pressure button) is probably the best thing to attach to your bow for fine-tuning. The plunger can be adjusted to help match an archer’s release and counteract a lot of archer’s paradox. For a better understanding of arrow selection, center-shot and Archers Paradox check out my earlier blog.

To set your center-shot, set you plunger to the middle and install it in the threaded hole. Attach an arrow to the string, below the nock, and from behind the bow check to see if the tip is pointing slightly to the left (or right for left-handers).

Although adjusting the plunger WILL require a trial and error approach, it is important to set the plunger to the middle position using the screw on the end. The amount of pressure setting for your plunger will depend on the archer, the limb poundage and your form. The best approach is to start with medium pressure and adjust accordingly after shooting a couple of arrows (Typically clockwise for more pressure and counter-clockwise for less).

Your bow should be basically setup and ready for you to focus on  developing consistent form. In upcoming blogs I will dive deeper into fine-tuning your bow.

Rests

Basically an arrow rest is part of your bow setup that holds the arrow in place, ready to be shot. Allen asked…

What kind of rest would you recommend for a beginner recurve shooter? I’m a COMPLETE newbie to archery, so I blindly went with the archery shop guy’s recommendations when buying my first bow. I ended up buying a Samick Polaris that he set up with a rug rest. Is this a bad kind of rest to use? Wouldn’t the two non-index fletches hit the bow on the way out? My arrows tend to hit the target at an angle instead of perpendicular, so I wonder if the rest could be causing it.

First lets cover the various types, most people say there are four basic types of arrows however I believe there are five; shoot-thru, containment, drop-away, pressure/plunger rests and the additional shelf. The shelf is often overlooked because it is part of the bow, however you do “rest” the arrow on it.

Here is a general overview of each type.

Shoot-thru (or prong) rest : A two-pronged arrow rest with a gap between and spaced about two-thirds of the width of the arrow to create a cradle. The arrow sits on top of the prongs with one fletching pointing down between them and is usually spring-loaded to allow additional clearance for the fletchings. These rests can be tricky for beginners because the arrow can fall off with wind or bad form.  They are best for hunting and the use of a mechanical release.

Containment rest : A totally encircled or a simultaneous 3-point contact arrow rest holding the arrow completely in place until release. These are the most common choice for archery hunting, they are relatively easy to install and tune. Great for beginner hunters since the arrow will not fall off the rest.

Drop-away (or fall-away) rest : Designed to drop out of the way upon release and therefore eliminate any chance of contact with the arrow. Activated by the release of the string, the rest holds the arrow long enough to keep straight and needs to drop out of the way before the fletching reaches the rest. Since this can be very tricky to tune; it is best suited for a compound bow. It is popular for hunting with large fixed-blade broad heads and helical fletchings.

Pressure/Plunger rest: Used commonly by finger shooters (no-mechanical release), they are designed to counter-act the horizontal oscillation from release with your fingers. Standard type bows without a cut-away, typically use a simple flipper rest (a rest with an additional “flipper” that acts like a plunger to help push-back against the pressure). Bows designed with a cut-away for your center shot typically use a rest along with an adjustable plunger. A pressure rest is used on Olympic bows and can be used be any finger shooter.

Shelf: Most traditional longbows and modern recurves bows are now designed with a cut-away area in the riser which includes a shelf area. For this type of bow instead of a pressure rest you can choose to shoot off the shelf. An arrow rest is attached to the shelf of your bow and is usually installed with an arrow plate to the side. They serve as protection for the bow and arrow and act as a soft, smooth surface for the arrow to be shot from.

Selecting a rest depends on a list of things including…

  • Type of bow (compound or recurve)
  • Chosen application (hunting or target shooting),
  • Type of release (finger or mechanical)
  • Budget (cold hard cash)
  • Experience (your ability to tune the rest and bow)
  • Form (some rests are more forgiving)
  • Tradition and historical nostalgia
  • Competition division (division restrictions)
  • And personal preference (bling factor)

There are a ton of rests available on the market and most bow manufacturers follow the same AMO (Archery Manufacturers Organization) standards. Therefore the drilling and tapping for the majority of bows are universal however before you purchase or upgrade make sure a selected rest will work and function with your bow.

A rug rest is a type of rest for a shelf and could be a very good selection for your shooting style if you are shooting traditional however it would not be the best selection for an Olympic archer or a compound hunter.  I am not in a position to recommend the best rest for your bow, since the bow is only as good as the alignment between the rest, release and nocking point. Obliviously, a better quality rest for your style of shooting can impact your accuracy.

To specifically address… My arrows tend to hit the target at an angle instead of perpendicular, so I wonder if the rest could be causing it.

A rest is only one small piece of the bow, and has very little to do with controlling the oscillation of the arrow. I would personally need to watch you shoot and inspect your bow to provide any valued and specific advice. There are a ton of things that can cause your arrow to impact the target on an angle. The bow may need tuning, you may be plucking the string, the arrows may be too stiff or too flexible, and a lot of other things.

Quick Insight: “Bows only perform actions as directed by you; so make sure you have good form first.”
