Exercise 1: Feather Wing Identification and Jig Clamp Dry Run

What you’ll do #

Before a single feather is glued, you will sort all 72 feathers by wing, confirm they are all left-wing, set up and calibrate the fletching jig with the left-offset clamp, and do a complete dry-run fletching sequence on one shaft — no adhesive, just mechanics. You will finish with a jig that is dialed in and a clear physical understanding of the 120-degree rotation sequence before any adhesive is mixed.

Setup #

Tools and materials needed:

• Your 72 left-wing turkey feathers (3 per arrow × 24 arrows)
• One spare shaft or one of your 24 finished shafts (use a shaft you have already inspected)
• Fletching jig with left-offset clamp installed
• A pencil
• A ruler or calipers
• Good light — natural light or a daylight-balanced lamp
• Optional: a sheet of white paper to lay feathers on for contrast

What is installed: fletching jig with offset clamp (fletching_jig_offset_clamp per your tool list). If the clamp is not yet mounted on the jig arm, install it now following your jig’s manual before starting this exercise.

Starter scaffold #

Work through each step below. Fill in the [TODO:] markers in your own notes as you go — these are the decisions and observations that make this exercise a calibration record, not just a setup task.

Step 1 — Sort and verify wing direction #

Lay all 72 feathers on your white paper, quill ends pointing toward you.

The identification test: Hold one feather with the quill pointing toward your chest, the tip pointing away. Look at the curve:

• If the feather arcs to your left, it is a left-wing feather. This is what you need.
• If the feather arcs to your right, it is a right-wing feather and must be set aside.

Work through all 72. Group them: left-wing in one pile, any right-wing strays in a separate pile.

[TODO: Record the count]
Left-wing count: ___
Right-wing strays found: ___
Action taken (set aside / returned / discarded): ___

If you find right-wing feathers, do not use them. Even one right-wing feather on a shaft will cause the arrow to fight itself in flight. Set them aside and source replacements before proceeding.

Step 2 — Check feather consistency within the left-wing pile #

Within your left-wing pile, feathers should be roughly consistent in:

• Length (the feather profile length, not the quill)
• Height (the tallest point of the vane above the quill)
• Quill thickness (very thick quills may not lie flat in the clamp)

Group any outliers (exceptionally thin or thick quills, significantly shorter or taller feathers). These are not necessarily unusable, but note them — if you have 12 arrows’ worth of consistent feathers and 12 arrows’ worth of slightly inconsistent ones, fletch the first batch first so any clamp adjustments happen on the easier material.

[TODO: Note any outliers]
Feathers with unusually thick quills (count): ___
Feathers notably shorter or taller than the majority (count): ___
Decision on outliers: ___

Step 3 — Load the jig and set the trailing-edge stop #

Load your spare shaft into the jig cradle, nock-end toward the clamp arm.

Adjust the nock-end stop so that when the clamp arm is lowered, the trailing edge of the clamp channel (the end nearest the nock) will position the feather’s trailing edge 1/2 inch to 5/8 inch forward of the nock valley.

Measure this with your ruler. This is the finger-clearance zone — feathers positioned closer than 1/2 inch from the nock valley will catch your draw fingers on every shot.

[TODO: Record your stop setting]
Measured distance from nock valley to clamp trailing-edge position: ___ inches
Within 1/2"–5/8" range? (yes / no): ___
Adjustment made (if any): ___

Step 4 — Dry-run the cock feather at position 1 #

Load one left-wing feather into the clamp — quill side down, facing the clamp channel. Do not apply any adhesive.

Lower the clamp arm onto the shaft. Apply gentle hand pressure as you would during a live fletching session.

Observe the quill contact along its full length:

• Does the quill lie flat against the shaft surface from end to end?
• Is there a gap in the middle (quill arching away from the shaft)?
• Is there lift at the trailing edge (the end nearest the nock)?

[TODO: Describe what you see]
Quill contact quality: ___
Location of any gaps or lifts: ___

If the quill lifts in the middle, your offset angle may be too aggressive. Reduce it by 0.5 degrees (consult your jig manual for the adjustment method) and repeat. If the trailing edge lifts, check that the feather is fully seated in the clamp channel — a feather that sits proud at the trailing end will lift in that zone.

When contact is flat and even: raise the clamp arm and remove the feather. Mark the shaft lightly with a pencil at the nock end to indicate cock feather position. This is position 1.

Step 5 — Index to position 2, dry-run the first hen feather #

Rotate the jig’s index ring to position 2 (120 degrees from position 1).

Load another left-wing feather and repeat the dry-run: lower the clamp, observe contact, raise the clamp.

[TODO: Describe contact quality at position 2]
Quill contact quality: ___
Any adjustment needed: ___

Step 6 — Index to position 3, dry-run the second hen feather #

Rotate to position 3 (120 degrees from position 2; 240 degrees total from position 1).

Repeat the dry-run.

[TODO: Describe contact quality at position 3]
Quill contact quality: ___
Any adjustment needed: ___

Step 7 — Sight down the shaft and check rotation symmetry #

With pencil marks from all three dry-run positions visible on the shaft, hold the shaft at arm’s length and look at it from the nock end.

The three marks should be evenly spaced at 120 degrees each. If they appear uneven, your index ring may have slipped between positions. Reset and repeat steps 4–6.

[TODO: Confirm symmetry]
Three marks evenly spaced at 120°? (yes / no): ___
If no, describe the deviation and corrective action: ___

Verification #

You have completed this exercise correctly when:

1. All 72 feathers are confirmed left-wing (or right-wing strays are separated and accounted for).
2. The jig stop is set so the trailing-edge position measures 1/2 inch to 5/8 inch from the nock valley — measured and recorded.
3. Three dry-run passes (one at each position) produced flat, even quill contact at every clamp position.
4. The three pencil marks on the shaft are evenly spaced at 120 degrees when viewed from the nock end.
5. Your [TODO:] fields above are filled in with real measurements and observations.

You do not need to have glued any feathers to pass this exercise. The purpose is jig calibration — if the jig is not dialed in before the first live session, you will discover the error on arrow 4 or 5 and have to strip and re-fletch.
