Install the Whistling Birds

Parts and Bench Check

Start with the assembled Whistling Birds gearbox/module, the activation magnet and reed-switch lead, the LED rows, the front nozzle mount, the rear bracket (standard or large-flange), and the twelve Fiber Optic Beskar Darts: one inner-row dart, four middle-row darts, and seven outer-row darts.

1. Power the module on at the bench. Before anything is glued into the gauntlet, confirm the module powers up and the push arms extend and retract cleanly.
2. Plug in the reed switch and test the magnet. The magnet is used to arm/disarm the prop during setup and later gets mounted to the hand plate. Confirm the reed switch responds reliably before the module is buried in the gauntlet.
3. Plug in the LED rows and confirm they light. Verify all three rows are lighting up before you start sizing the Fiber Optic Beskar Darts. Fixing a connector or lighting issue on the bench is much easier than troubleshooting it after the fibers are installed and trimmed to fit.
4. Check the push-arm timing and alignment. Compare the mechanism with the bench-check close-up at 2:49: the long push arm should reach the pull-tab reference and the two short arms should be even with each other. Confirm this alignment before mounting the module.

Turn Firing Off for Installation

Before sizing the darts, set Firing Mode to Off. The prop can still arm, disarm, and light the darts, but wrist movements will not fire them while you are fitting the assembly. In the video this is done through the config menu by selecting the firing-mode option and choosing the red/off setting.

Mounting System

The front nozzle mount and rear bracket define the final position of the module. That position controls the dart length, so glue the mounts before final dart trimming.

1. Clear the gauntlet interior. Remove velcro, glue residue, print blobs, or internal ridges that keep the module from sitting flat or that could interfere with dart travel.
2. Scuff and clean the bonding surfaces. Lightly scuff the gauntlet and mount contact areas, then clean them with isopropyl alcohol. CA glue holds much better on a clean, textured surface.
3. Mount the rear bracket first. Dry-fit the module with both mounts and position the gearbox as far back as practical while keeping it centered on the nozzle holes and able to clip in and release. Mark the rear bracket position, remove the module, and glue the rear bracket at the mark. Greater distance from the nozzle housing gives the fiber optics more room to align with the holes and can reduce friction.

   

4. Position and glue the front nozzle mount. After the rear bracket has set, seat the module in it and use the module to locate the front mount naturally. Keep the center notch aligned with the center nozzle hole. Apply a thin, even layer of glue, press the mount in place, and hold alignment while it sets.

   

Route and Connect the Darts

With the mounts installed, install the Fiber Optic Beskar Darts from inside the gauntlet, feed them out through the nozzle holes, and connect the LED housings to the gearbox push arms. The goal is to confirm the darts can move in the actual installed position before final trimming.

1. Nest the three rows and feed the darts through the nozzle holes. Place the single inner row inside the four-dart middle row, then thread both through the outer row's crossbar so the rows stack together. Feed the darts from inside the gauntlet out through their matching nozzle holes. See the row arrangement at 30:59.
2. Retract the arms and seat the module. Disarm the unit so the push arms are retracted, then slide the module into the front mount and rear bracket. Keep the fibers routed through their holes and the wires clear while seating it.
3. Connect the LED housings to the gearbox arms. The inner- and middle-row housings connect to the short push arms with a French-cleat interface: guide each housing onto its cleat and seat it fully at its working angle. Move the outer row aside as needed to reach these connections, then guide it onto its tab-style connection. The installed hookup at 32:15 shows the method through the gauntlet opening. Handle the wires gently. Leave a slack loop and keep it clear of all moving parts. The wires can help position a housing for connection to its push arm, but avoid pulling hard.

Size and Trim the Darts

There is no universal dart length. First sort the Beskar tips by height: the longest goes in the center, the next-longest tips form the middle row, and the shortest form the outer row. Select one reference dart from each row, as shown at 14:34. Gauntlet geometry varies, so size each reference in the installed, armed position and use it as the starting reference for the remaining darts in that row.

1. Arm the unit so the row is fully extended. Decide where the visible tip should sit at full extension.
2. Check the visible side and brightness before marking. Hold the painted shell where you want it, find the brightest angle that still keeps the prettier side facing out, then note how much extra length remains at the back and remove the dart.
3. Trim only the back end. Cut slightly long on the first pass. Reinstall, arm the prop, and check the extension again.
4. Repeat until the reference dart is correct. The tip should disappear cleanly when retracted, land near the desired nozzle position when extended, and keep its best brightness with the preferred painted side still facing out.
5. Use the finished reference for the remaining darts in that row. Match from the finished tip ends so the visible tips stay aligned, then still test-fit each dart individually.

Find and Remove Friction Points

If a dart does not retract fully, watch where it catches before removing more material. This can happen with different gauntlet designs; the friction check at 24:05 shows the process.

1. Find the contact point. Check the rear edge of the Beskar tip, the nozzle opening, and any interior rib for a sharp edge that catches during travel.
2. Smooth only the catching edge. Remove the dart and lightly round the rear edge of its tip shell where it catches. Smooth the corresponding nozzle edge or interior rib as needed, taking off only a little material at a time. Keep the visible tip intact.
3. Reinstall and recheck both directions. With Firing Mode still Off, arm and disarm to confirm the dart extends and retracts freely before gluing. Use optional graphite only after correcting the fit and clearance.

These are separate adjustments: trimming the back of the fiber sets dart length; rounding a catching edge of the tip shell or nozzle reduces friction; chamfering the fiber's LED-facing end can improve light transmission. Do not keep shortening the fiber to solve a catching edge. On some Galactic Armory shells, the interior rib just behind the nozzle is the contact point to check.

Final Alignment and Glue

Before gluing, confirm the dart’s final length, orientation, and light transmission. A small chamfer at the back can improve how the fiber receives light from the LED, but do not shorten the dart enough to change its finished position.

1. Confirm size and brightness one last time. Make sure the painted shell still shows its preferred outward-facing side at the brightest usable angle. If you chamfer the back end, keep the angled face toward the LED.
2. Glue one dart at a time. Use a tiny drop of CA at the back/base joint and let it wick into the connection.
3. Keep neighboring darts separated while the glue sets. Too much glue can bond adjacent darts together or block light at the LED housing.
4. Confirm brightness after each glue-up. Check that the finished tip still lights all the way before moving to the next dart.

Final Assembly and Activation Magnet

After the glued darts and mounts have cured, repeat the row nesting and installed hookup steps: nest and route the rows, retract the push arms, seat the module, then connect the housings. Recheck for friction before the final motion test.

1. Mount the reed switch. Mount the reed switch as far forward as possible inside the gauntlet (this positions it closest to the hand-plate magnet) and plug its JST into the connector at the front of the gearbox.

   

2. Leave a small wire loop at the front. The harness needs enough slack to move without pulling against the module.
3. Tuck the wires and seat the wire cover. Tuck and route the wires out of the way, placing the LED JST in the battery compartment to keep the LED area open, then seat the wire cover.

   

4. Reinstall the battery cover carefully. Seat the cover tabs, keep the power button aligned with its wall/holder, and make sure the wires sit in the side guide instead of getting pinched.
5. Check arm/disarm with Firing Mode still Off. Cycle the unit several times to confirm the rows extend and retract without binding and the wire loops stay clear throughout the movement. Complete fitting and cover installation before testing firing.
6. Mount the activation magnet on the hand plate. Affix the 20×10×3 mm magnet to the back edge of the hand plate using hot glue or another removable adhesive so the position can be adjusted. A deliberate wrist-up motion should reliably trigger the reed switch without false triggers at rest.
7. Restore and test your preferred firing mode. Once fitting is complete and arm/disarm works freely, open the config menu and select Tilt or Shake if desired. Then test that mode to confirm the rows complete their firing and return movements without binding. If you prefer to leave Firing Mode Off, keep it Off.
