Fabrication Instructions
The following steps outline the fabrication process for the Original Shuttle Lock.
Mold Preparation
Diagrams illustrate mold preparation steps, showing components like the distal socket plug, threaded plug, and mounting nut. The process involves:
- Seat set screw (#880490) in the desired location on the mold.
- Coat the distal surface of the distal socket plug (#125315), the threaded plug (#125314), and the plug screw (#125317 or #125348) with stick wax (#990035).
- Fill the hex cavity in the threaded plug, the lateral hole in the distal socket plug, and the socket of the plug screw with silicone gel.
- Blend plaster from the mold to the distal socket plug.
- Assemble the mounting nut onto the threaded plug screw (125314).
- Place the assembled mounting nut and threaded plug onto the distal socket plug, ensuring the flattened corner of the distal end faces the button hole for the desired medial position of the release button.
- Press the mounting nut down firmly onto the plug until it is seated squarely.
Thermoforming
Standard drape or blister forming techniques may be used with sufficient vacuum. Special care should be taken around the area of the button shield to prevent wrinkles and thinning, especially during blister forming. Buildup for the frame and attachment is then made with plaster or foam. The rigid outer frame is then thermoformed using any customary plastics.
Two-Stage Lamination
The inner shell is constructed from Dacron and/or Nylon. Ensure no air bubbles remain over the fabrication dummies. Buildup for the attachment is then made with polyester or foam. The second stage is laminated with the desired reinforcement scheme using carbon, fiberglass, and nylon.
One-Stage Lamination
The Regular Shuttle can also be used in a one-stage lamination technique, utilizing a pyramid socket adaptor as the distal attachment (refer to the Fillauer One-Stage Lamination Manual). The Unitized Shuttle Lock Housing with Pyramid (#809750) may also be used, which secures the pyramid attachment under the shuttle lock.
Assembly
Diagrams show the Shuttle Lock Assembly with the button shield and button hole options. The assembly process involves:
- Trim plastic around the threaded plug (#125314) flush with the Distal Socket Plug (#125315). Also, trim plastic flush with the Plug screw (#125317) or Plug screw for Shield (#125348).
- Carefully remove the interface from the mold to reassemble the shuttle lock.
- Insert the Shuttle Lock Body (#809747) into the distal cavity.
- Screw on the Mounting Nut (#809732), drawing the Lock Body distally.
- Place the Guide Screw Assembly (#809712) inside the Button Shield (#125345).
- Push the assembly through a 1" Pelite Washer (#809758) and screw it into the Shuttle Lock Body.
- Cut the Latch Pin (#809731) to the desired length.
- Screw on the Latch Pin Button (#809730) and secure it with blue Loctite.
- Push the Latch Pin through the 3/4" Pelite Washer (#809757) and thread it into the shuttle through the Screw Assembly.
- The Pelite washers are required to baffle air escape and prevent noise.
