Damp/Damping/Damps
Any system which, when set in motion, creates a force which inhibits that same motion, is said to exhibit damping. Damping forces are usually created by friction, either aerodynamic (external) or material (internal). *(Most true damping with regard to fishing rods is caused by air friction. Some internal material friction does exist, however.) Although most often incorrectly used within the confines of rod building, the term is generally used and understood to describe how long a rod takes to return to straight or s, after being cast or flexed, i.e "This rod damps quickly."
DBI
Defined Binding Index. Part of the Common Cents System. Provides a quick reference to the Effective Rod Number and Action Angle (ERN/AA).
De-Gloss
To scour or scuff a glossy surface until any shine or gloss has been completely removed.
Density
Weight per amount or unit of volume. Can be measured as lbs/in3.
Diamond Wrap
A type of decorative thread wrap where threads are wrapped to each side of the pattern in order to form boxes or widen the basic "X" shape. Viewed from any corner (and depending upon the elongation of the pattern), they appear diamond shaped.
Do
An instruction used on a weaving "Left List" meaning to repeat the previous step.
Downlocking
Used to describe a reel seat that has been mounted with the fixed hood to the rear (butt) and the movable hood to the front (tip).
Drop Shot Rod
Specialty rod with very light tip used for fishing a plastic worm or lure above the sinker. The light tip allows minute movements to be imparted to the lure. Generally these are light power rods.
Drum Dryer
Type of 'Rod Dryer' where large round flats are used to hold a number of rods on the circumference and the entire assembly turns around a center shaft. Resembles a drum mounted and turning on a center axis.
Drying Motor
A slow RPM motor used to rotate a fishing rod to prevent slow curing thread finishes/coatings from dripping or sagging until they have set.
Durometer
The international standard for measuring hardness of rubber, plastic and other non-metallic materials. Often used to define the hardness of fishing rod grip materials. Also, the instrument for taking these measurements is referred to as a Durometer.
Equal-Angle System
A guide placement system based on consistent protracted angles plotted to intersect a rod blank. Develop by rod builder Don Morton.
Equal-Distance System
A guide placement system based on each guide remaining an equal distance from both the previous and subsequent guides.
ERN
Effective Rod Number. Part of the Common Cents System which provides a relative measure of intrinsic power.
EVA
Ethylene Vinyle Acetate synthetic foam material. Available in various grades and hardnesses, the more firm variety makes an excellent and lightweight rod grip material. Not as resilient as Hypalon, but considerably lighter in weight.
Exothermic Heat
Heat released from a chemical reaction. The opposite of "Endothermic Heat." Normally rod builders exerience this heat when mixing two-part adhesives and finishes. The reaction of the parts creates and releases heat.
Fast Tip
Normally used to describe a rod with a very fast action. A rod with a powerful butt section and a much softer tip.
Feralite Ferrule
A type of Tip-Over-Butt ferrule designed by Jim Green at Fenwick. The first Tip-Over-Butt ferrule.
Ferrule
An item which allows sections of a rod blank to be joined together. Can be either separate or integral to the rod blank sections.
Fighting Butt
Normally used on fly reel seats. A short extension of cork or foam, either fixed or removable, on the rear of a fly reel seat.
Fighting Chair
Special chair mounted to a boatıs deck and used to allow an angler to fight a fish from a sitting down position. In use, the rod is placed into a gimbal nock on the chair, which then becomes an aid to the angler against large and powerful fish.
First Quality
Generally refers to a rod blank that is offered as a first quality product and comes complete with a manufacturer's warranty.
Five-Minute Epoxy
A two-part epoxy adhesive with a very short (5-minutes or so) working or pot life.
Fixed Hood
The hood on a reel seat that is fixed and cannot be adjusted or moved.
Flag
The pattern cut from a prepeg material which is wrapped around a mandrel to form a rod blank.
Flipping Stick
Term popularized by tournament bass fishermen for a stout rod used for accurately "flipping" a lure or bait into close quarters. Usually long (7' or more) and often telescoping to allow fitting into short rod boxes on bass boats.
Float Rod
Used for a variety of species. Available in both very fast, light tipped models, as well as more moderate action models, these rods are usually quite long (12' to 14') and used for fishing with a variety of float styles. Originated in the U.K. for "Coarse Fishing."
Football
Term used to describe the shape of a finished guide wrap when the finish is thicker in the middle than at the edges. Shaped like a football.
Foregrip
The grip installed in front of the reel seat on casting and spinning rods.
Forhan Locking Wrap
Guide wrap developed by rod builder Rich Forhan. Completely encircles and secures single foot guides.
Foulproof Guide
Name associated with a particular type of line guide which is fashioned from a single piece of wire. It is wound into a circle or coil, with the ends of the wire serving as guide feet on either side of the circle.
Full Wells Grip
Fly rod style grip. Swelled on both ends and in the middle with depressed areas about 1/4 length in from each end.
Gimbal
A butt cap with cross slotting on the end. These slots locate into a pin used in a gimbal nock, which may be located in a fighting chair or fighting harness. Prevents the rod from turning or twisting during a fight or while trolling a bait or lure.
Glue
Bonding agent made from natural sources.
Half Wells Grip
Half of a "Full Wells" grip. Swelled at one end and the middle, with the opposite end tapering to a smaller overall diameter.
Hood Liners
Usually made from plastic or nylon and used to line reel seat hoods of steel or aluminum. Prevents marring of the reel foot and provides an elastic cushioning effect.
Hookkeeper
Small ring or hook wrapped near the foregrip on a fishing rod intended to hold the lure or fly when rod is not in use.
Hosel
Used to finish off the forward edge of a rod foregrip. Similar to a cap with a hole bored in the end for the rod blank to pass through. Mostly of a decorative nature.
Hot Shot Rods
Stout butted yet very light tipped rods designed for use with swimming/diving plugs which are fished while stationairy or drifting. The river or stream current causes the plug to dive and hold near the river bottom. The angler watches the action of the plug by the movement of the light rod tip and the heavy butt section usually sets the hook on the fish. May be used for many other fishing applications as well.
Hypalon
Trademarked name for a Chlorosulfonated Polyethylene synthetic rubber product. While it is used in a variety of industrial applications, it has long been used with good results in the form of rod grips. Somewhat heavy, but extremely resistant to sunlight, solvents and detergents.
