Arrows Series – Part 8: Fine Tuning and Numbering

Now that your center-shot is right, you’ll need to continue to fine-tune your bow periodically to change as you grow and develop as an archer. Start by labelling and numbering your arrows. Labelling your arrows with your name or initials is required for tournaments and sometimes is the only way you can distinguish your arrows from someone else’s; especially if they have the same nocks, shafts and fletchings.

Numbering is a good idea so you can track your arrows, if you have a single stray arrow. If the stray is consistent on every end and the number is the same, it may be that something is not right with that arrow.

Once you know your arrows and can track them, you can further tune your bow by adjusting various components such as the tiller, plunger, nock height etc… . You can perform some or all of these various tuning test to help tune your bow for maximum performance.

Paper Tuning Test: Tuning test involving setting up a piece of paper on a frame, stretching the paper taught, and shooting field-tipped arrows (not broadheads, which will affect the arrow flight) through it starting about 6 ft away.

Bare Shaft Planing Test : Tuning process were one shoots a bare arrow (shaft with no fletchings) for comparison with fletched arrows.

Walk-back Test: Tuning process where groups of arrows are shot at increasing distances to give a useful combined test of both centre-shot and button tension.

Check out these two very useful resources: Easton Tuning Guide and Tenzone’s Bow Tuning test documents: for instructions with these tests and many more.

As you develop as an archer you will need to make changes and tune your bow. Remember that making multiple adjustments at the same time can be hard to track and can be very confusing. It is important to only make one change at a time and test again.

This concludes the Arrow Series; Thanks and good shooting.

Twisted Limbs

Arguably, the MOST important part of the bow are the limbs, since the movement of the limbs transfers energy to drive the arrows to the target. Investing in well-manufactured limbs can be the best move any archer can make. Since consistency is the number one requirement for any archer, you want to avoid any twists. Wood/Fibreglass limbs perform well however can be prone to warping in areas where temperature changes a lot. Carbon fibre layers help strengthen the limb and reduce the tendency to twist.

After purchasing a new set of limbs, one of the first things an archer should do is align their limbs to their riser. Alignment of the limbs means the string should appear to run right down the center of the limbs thru the center of the riser.

I highly recommend the purchase of a new set of limbs for any archer; however, the purchase of a good used set can be an option for a new archer who is still learning the sport. When purchasing a used set remember any twist will cause inconsistent flight of arrows, check for limb distortion (often called limb twist). Viewing the bow strung with the limbs from either end of the bow, if one or both of the limbs have a slight twist, you may have limb twist.  If the distortion is only slight sometimes it can be cured with one of three methods.

1)       Cold Bump Method

Attempt to straighten the limb using the “cold bump” method. If a limb has developed a slight twist from improper stringing, this method often will correct the problem. Grab the bow by the riser with your dominant hand. Use your other hand to grip the bow limb slightly above the twist. Slowly twist the limb in the direction opposite of the distortion, and then quickly release the limb. Repeat this process several times until the limb properly is aligned.

2)       Warm Wet Submerge Method

Submerge the twisted limb in a tub of hot water for 3 to 4 minutes. The water should be no warmer than a hot bath, around 105 degrees Fahrenheit. This is just hot enough to mildly loosen the glues in a laminate. Remove the limb from the water, then slowly twist the limb in the direction opposite of the distortion. Release the twist slowly and examine the limb for straightness. Repeat the twisting procedure several times until the limb is straight.

3)       Low Heat Method

Twist the limb in the direction opposite the distortion and hold it in place. Have an assistant heat the limb using a hair dryer. Hold the hair dryer 6 to 10 inches from the limb, and slowly move it up and down the length of the limb. Heat the limb slowly for 2 to 3 minutes, then release your hold and examine the limb for straightness. Repeat the heating procedure as necessary until the limb is straight.

In my opinion, it is not worth playing with twisted limbs or possible physical injury and especially where ranking is important, competitive archers should not risk the possible performance dip . New well-manufactured limbs are very forgiving of a poor release, feel smooth and are more affordable than ever. Cartel Doosung and Bow Korea offer a complete line of limbs for everyone including introductory limbs, the new Midas MPS limbs for intermediate archers and MK Archery Vera/1440 limbs for competitive archers.

Follow the Arrow: Adjust your sights

Unless you are a traditionalist, one of the first things you will need to do as an archer is adjust your sight. Unless you are a compound shooter with the same setup for ever, you will need to make adjusts again and again. For recurve archers there are many reasons why you will need to make adjustments including…

Environmental Differences : Every location is different, wind, rain; check out my earlier blog about Weather Conditions here.

New Distances : As you develop and change categories, distances change. Junior women need to shoot 70M and junior men 90M, if you are not there yet, do not worry, you will be.

Growth : As you get older, your body changes, you get taller and stronger and your draw length changes, using a clicker can help with consistency, so check out my Clicker blog.

Equipment Changes : As you get stronger and you are required to reach longer distances you need to change equipment, such as higher poundage limbs. Eventually equipment wears outs and we all want the latest and greatest technology.

Archery Form Changes : As you develop as an archer, you will perform better as an archer and your archery form will get better.

For young recurve archers adjusting a sight is a frequent event and is actually quite easy, the hard part is resisting the temptation to adjust it after every shot. Remember that consistency is your ultimate goal, so track your arrows before making any adjustments. You can do this on paper or there is an awesome free application for your IPod Touch called Archery Score Free by Yakoob Ali.  Once you are warmed up begin to track your arrows and determine the centre of your arrows grouping and then move the sight accordingly. Remember, if your groups were good yesterday and are not today, evaluate your form first. Also, if you have one arrow consistently out of group, check the arrow for defects.

When you are ready to adjust your sight, apply this simple rule, “Follow the arrow” or in this case the centre of the group of arrows. If the centre of your arrow grouping is to the left, then move your sight towards the left or opposite if your group is to the right.  The same principle applies for the group’s height; move your sign up or down if the group is not centered.  By moving the sight towards the arrow, the trajectory of the bow is altered to better centre the arrows on the target.

Remember, consistent form is essential to archery, and before you start micro-adjusting be sure you are grouping consistently first. Otherwise, if you are always making changes to your sight you will never truly know if you will consistently hit the bulls-eye.
