FLETCHING ARROWS

Fletching arrows like many things is a matter of following steps and paying attention.
P1000641
Not every step is crucial but if you want your feathers/vanes to hang on when you accidentally shoot through a bale or clicker and or when you’re shooting tight groups it pays to have paid attention to the details.
Big hint number one for success is to work clean. Start by washing your hands to keep your natural skin oils away from the surfaces you’ll be applying glue to, keep your work area clean, and if you just ate mama’s fried chicken, scrub up well!
Next on the cleaning list are your shafts, when I first started fletching my own arrows my local shop sold me  a shaft cleaner made by AAE, but any powder cleaner like Ajax or Comet will do the job.
Put it on and scrub it in with a clean abrasive pad. See pic below.

Once you’ve cleaned your shafts well, rinse them with warm water, I like to use hot water so they air dry faster.

This next step is crucial, whether you’re fletching carbon or aluminum arrows is to abrade/scuff the surface you’re going to glue to, so the glue has something to hold on to, specially with aluminum arrows which are slick indeed.

I use 3M’s 7447 Scotch Brite Pad, some folks use steel wool or very, very fine (600 grit) sandpaper.
When I abrade the surface I do it in a left to right motion or at right angles to the shaft. Depending on the arrow, this usually means that I’m going across the grain, increasing my chances for good adhesion.
If you’re fletching carbon shafts there will be some carbon dust residue on your shafts, I usually wipe them with a clean rag.
Now that you’ve prepped your shafts you’re ready to glue your fletchings on. The majority of fletchings are glued on by using a fletching jig to guide the placement of your feathers or vanes onto the arrow and hold them there while the glue sets.

Here is the clamp holding the feather against the shaft while the glue sets, the clamp is held to the jig by a magnet.
Once I have the feather or vane in the clamp I apply a consistent bead of glue. I always have a rag nearby to deal with excess glue from the tube, which often continues to ooze wanting to make a mess.
P1000581
If I am gluing vanes I leave the vanes in the jig just a short time, 30 seconds to a minute. If I am gluing feathers and this depends on what you’re using for glue. I leave them in a lot longer. Feathers have some natural curvature to them, when you put them in a clamp you are changing that shape. The feather wants to spring back to it’s natural shape. If you pull the clamp early, before the glue has dried enough you risk the feather springing off the glue line.
P1000585
Once I’ve glued the vanes or feathers on, I will dab spots of glue on the leading and trailing edge of the fletching. This is cheap insurance and makes a difference in longevity.
Lastly I let them dry, preferably overnight. Depending on the glue you may be able to shoot them much quicker than that, I figure if I have the time it doesn’t hurt to let the glue fully cure.
There are clamps for  jigs that will angle your vanes or feathers differently on the arrow, how they are set on the arrow affects arrow flight. Find info on these clamps below.
Straight: There is no angle on the feather or vane, often commercially purchased arrows which come pre-fletched are straight fletched. With certain types of arrow rests it is preferred as the arrow can’t catch, think whisker biscuit arrow rests.
Offset: The fletching is angled on the shaft 1 or more degrees, this induces rotation  which has a gyroscopic effect on the arrow for a more stable flight.
Helical: Is angled on the shaft and also has corkscrew like bend (helix) to the fletching. Helical can provide the maximum amount of rotation, which means more stability in flight. It also means more drag than straight or offset making for a bit slower arrow than straight or offset.
Left or Right: Choose to have your feathers/vanes angle right or left, it doesn’t matter which.  When purchasing a fletching jig you will have to decide whether you want left or right clamps, also when buying feathers you have to indicate whether you want left or right feathers. Vanes are straight and can be used in either direction.
Personally I like an offset or helical, getting the arrow to spin and be a bit more forgiving.
Lastly, I’d like to mention the distance from the end of the arrow to the fletching, this

changes depending on whether you are shooting with fingers or a release. The above arrow has 1 1/2 inches of clearance because it will be used with a finger release. When using a mechanical release you can have them further aft. The further back the better.
I have really enjoyed fletching my own, it gives me more control of the whole process, gets me involved in the craftsmanship of archery and opens a window into how things in archery work and why. You may want to give it a go yourself.

ARROWS SELECTION

One of the ongoing costs for archers is arrows, this is especially true for young archers that are still growing, and their draw length is constantly changing. Once an arrow has been cut and sized, you can only make so many adjustments to a clicker before you will outgrow the arrow length and need to purchase new ones.
One of the biggest questions for competition archers is what type of arrows should I use and what will give me the best performance for how much I can afford.
Historically, this was easy since there were only wooden arrows, however nowadays there are real choices, aluminum or carbon fiber.  Aluminum shafts have been  steadily replaced wooden arrows since their introduction in 1939 however in the 1980’s, carbon fiber shafts were developed as the new technology to challenge aluminum shafts.
Which one should you use? There are no easy answers; it is a personal preferences and both have advantages and disadvantages. There are four key areas to examine; durability, flexibility, diameter and price point.
Durability
Aluminum arrows can be bent easily as they collide with obstructions, other arrows and the target itself. Sometimes, bends can be repaired however; the shaft is weakened and more likely to bend again in the same spot.
Carbon fiber arrows remain straight as the day you buy them until they break. If a carbon fiber is damaged it can be extremely dangerous to shoot with and will need to be replace immediately.
As far as durability is concerned, carbon fiber arrows have the biggest advantage.
Flexibility
Aluminum Arrows are more likely to sustain damage from impact because the shafts are rigid.
Carbon arrows resist damage because they are more flexible. They easily adsorb the energy vibrations transferred during impact of the target.
For consistently accurate competition archers, carbon fiber arrows have the advantage. For beginners this is not a real factor.
Diameter
The diameter of an arrow is very important for shooting outside. The larger the arrow the greater the wind effects the arrow, this is called wind drift. Younger archers with shorter draw length can achieve greater distances be more accurate with thinner arrows.  Although aluminum arrows traditionally have a wide range of sizes available thinner diameters can be achieved with carbon fiber because they are lighter.
In my opinion, this is a draw and it depends on the archers requirements.
Price Point
Obviously, this is the most important factor for a young archer, since it depends on your budget. Aluminum arrows are usually more inexpensive and therefore more widely used by young archers. However, the cost of carbon fiber arrows are dropping, such as the new Cartel Triple Arrows which are often compared to Easton’s A/C/E’s in quality however are more affordable.
If you are interested in purchasing arrows, you need to select the appropriate arrows for your draw length and bow poundage. Having arrows that are too rigid or too flexible will yield inconsistent and unexpected results.
Most manufacturers provide a chart to help archers select the correct arrows. For target archers you need to consider the poundage you actually draw and not just the overall limbs poundage. For Cartel Triples (Carbon Fiber) or Cartel X-pert (Aluminum) arrows check out the following selection chart for recommended Cartel Triple and Cartel X-PERT size selections.
