- Arrow Rest
The arrow rest is the unit that screwed into the riser via the berger hole on a compound bow and provides a catch for the arrow to rest on before and during the shot. Models are either stationary while some mechanically “drop away” during the shot.
- Arrow Shelf
The arrow shelf on a compound bow is the horizontal shelf designed into the riser which contains the arrow in all stages of the shot. It also protects the gripping hand from accidental injury.
- Berger Hole
The Berger Hole is the tapped hole above the arrow shelf on a compound bow. The arrow rest is screwed into the berger hole from the outside of the riser. It is standard to have your arrow centered on the center of the berger hole when setting up the bow.
- Bow Sling
A compound bow wrist sling is installed in tandem with a stabiler. It provides a “catch” for an archer so they do not drop the compound bow after taking a shot. Bow slings should be installed loosely so they do not add unneeded torque when the shot is fired.
- Bow String
The Bow string is the string, on a compound bow, which terminates at the cams on a two cam system. On a “solo cam” system, the bow string’s ends both terminate at the bottom cam but travels around the top idler wheel.
- Brace Height
Brace height on a compound bow is the measurement from the crotch of the grip to the bow string. The average brace height is around 7 inches.
The cables on a compound bow run from cam to cam and work with the cams during the execution of the shot.
- Cable Guard
The cable guard on a compound bow is the fiberglass rod which runs perpendicular from the riser towards the bowstring and works with cable slide to keep the cable(s) out of the arrow’s line of fire.
- Cable Slide
The Cable slide on a compound bow is a plastic piece which attaches to the cable guard and holds the string / cables out of the arrow’s line of fire.
Cams of a compound bow are round to oval metal discs which are held in place to the limbs via a pin and they are where the string and cable(s) terminate. They are attached at the end of the limbs and transfer the power of the limbs to the string and arrow during the shot. Bow’s will either have one or two Cams. On a Solo Cam bow, the cam will be attached to the bottom limb of the bow while an idler wheel will be attached to the top limb.
A D-Loop surrounds the arrow at the string and is a point of connection for a mechanical archery release; it is made or a short piece of cord fastened to the bow string by two knots.
- Fletchings / Vanes
Fletchings are the feathers or plastic vanes which are glue to an end of an arrow that steer and correct an arrow during flight. They can be oversized to dramatically reduce speed ( for bird shooting ) or undersized for increased speed.
The grip on a compound bow is the part of the riser that you hold when shooting. Most manufacturers install a removable grip which can be replaced with an aftermarket grip to suit an individual’s comfort.
Compound bow limbs are the flexible fiberglass planks that are attached at the riser on one end and support the cam or idler wheel on the other. They work with the shooter to store and release the kinetic energy need to deliver a shot. With most bows, the limbs are given a poundage rating: 50-60lbs, 60-70lbs, 70-80lbs, etc. If an archer wanted to raise or lower their draw weight outisde of the 10 pound range that their limbs provide, they can do so by replacing the limbs with the preferred weight rating.
The nock is the insert on the rear end of the arrow which attaches to the bow string. A nock may also refer to the crimpable collar which some archers attach to their bowstring at the “nocking point.”
- Nocking point
The nocking point is the location, on the bow string, that the arrow attaches to before a shot.
- Peep Sight
The peep sight is the donuts shaped device inserted between the strands of the bowstring which gives the archer’s eye its first point of alignment. When the archer lines up his sight while he is viewing through the peep sight consistency is more obtainable.
The quiver is the permanently mounted or detachable unit which contains the archer’s arrows. Some have one or two points of holding contact on the arrow and a head either filled with a foam product or hollow. For mechanical broadheads we suggest using a quiver with two points of contact on the arrow and with a broadhead containment compartment which is hollow; this keeps the mechanical broadheads from unnecessarily deploying the blades and limits wear and tear on crucial broadhead components.
The riser is the central component of the bow which is normally constructed out of machined aluminum.
An archery sight attaches to the riser and contains pins, cross hairs or a laser dot which the archer can adjust to make a more accurate shot.
- Silencing Aids
Silencing aids are various accesories which can be purchased and installed on a bow/bowstring to absorb vibration to quiet a shot. These attach to either the bowstring, cables, limbs, or the riser.
The stabilizer is an optional accessory which is installed in the tapped hole below the grip and on the front of the bow. Stabilizers stabilize the bow at full draw giving the bow a different center of balance. When desired aim is achieved and the shot is taken, stabilizers maintain that line of aim resisting minor twitches/torquing during the execution of the shot. They deliver the same type of stabilization that a tightrope walker’s balancing bar. Stabilizers can be front mounted or side mounted and greatly increase accuracy when set up properly.
- String Vibration Arrester
This silencer, which is attached at the riser and or the ends of the limbs, has contact or near contact with the string prior to the shot and aborbs vibration during the shot which is directly transferred from the string.
- Tiller Measurement
The tiller measurement is the measurement from the point where the limb meets the riser and to the string in a perpendicular line. Each bow will have two tiller measurements and generally should be the same.
2 thoughts on “Hunter Diary 03 – Construction of Compound Bow”
Good morning Ken,
Please can you assist with advice?
I have purchased from you a “Glory” compound bow and I am new to archery, especially to compound bow ( many years ago I did do a field archery course, but with recurve bows).
I wish to set the compound bow for left hand shooting ( I have discovered I am left eye dominant).
I think I need to change the cable guard from right side to left, but do I need to reverse also the bow strings on the cams?
Is there any other alterations I need to conduct?
Please advise, much appreciated.
First of all thank you for your purchase.
There is no need to adjust the strings or cables.
Just install the cable guard to the other side as well as other accessories ( if there is any ) like arrow rest and bow sight.
Feel free to contact us if you have any further question.
