Description
J Perkins 1/2 x 3/4 Engine Bearer, part number 5521224, is a spruce wood bearer for model engine mounting and structural construction. It is supplied as a 12-inch length with a 1/2 x 3/4-inch profile, providing a solid section for supporting engine feet and mounting related components.
The long, straight grain of the spruce provides stiffness while keeping the bearer lighter than comparable hardwood sections. This structure can help manage the high-frequency vibration produced by internal combustion engines and reduce the transfer of movement into the surrounding airframe. The bearer also provides a flat mounting surface to help maintain alignment between the engine, firewall, propeller and drive shaft.
Spruce can be cut, drilled and shaped using standard hobby tools, allowing the section to be adjusted for the required engine mount arrangement or thrust line. The manufacturer describes this type of bearer for model aircraft and marine model construction. Its brown wood finish is suited to applications where the bearer forms part of the model's internal structure.

Engine Bearer
Exceptional Strength-to-Weight Ratio: Spruce offers the ideal balance—it's significantly lighter than traditional hardwoods (like Beech), yet provides superior stiffness and strength, ensuring your model’s weight remains low without compromising on durability.
Vibration Resistance: The long, straight grain structure of Spruce provides excellent rigidity, which is crucial for dampening the high-frequency vibration produced by internal combustion engines, protecting the surrounding airframe from fatigue damage.
The Structural Backbone: Engine bearers are the most critical structural part of the model's power train. They provide a solid, true surface for mounting engine feet and firewalls, ensuring perfect alignment of the propeller or drive shaft.
Easy to Work: Despite its strength, Spruce cuts cleanly and can be drilled and shaped with standard hobby tools, allowing you to easily customise the fit for your specific engine mount or thrust line requirements.
- Sizes: 3/8 × 3/8in, 3/8 × 1/2in, 1/4 × 3/8in, 1/4 × 1/4in, 1/4 × 1/2in, 1/2 × 1/2in, 1/2 × 3/4in, 1/2 × 1in
- Length: 12in
J Perkins 1/2 X 3/4 Engine Bearer Key Features:
- Exceptional Strength-to-Weight Ratio: Spruce provides a superior alternative to heavier hardwoods like beech, offering the critical stiffness and structural integrity required for high-stress powertrains while keeping overall model weight to a minimum.
- Vibration-Dampening Grain: Featuring a long, straight grain structure, these bearers are specialised to absorb and dampen high-frequency engine vibrations, protecting airframes and sensitive electronics from fatigue damage.
- Precision Mounting Surface: Acts as the structural backbone of the model, providing a perfectly true and solid surface for mounting engine feet and firewalls, ensuring precise alignment of the drive shaft or propeller.
- Professional Workability: Despite its high rigidity, spruce remains easy to drill, shape, and cut with standard hobby tools, allowing for effortless customisation of thrust lines and engine mount configurations.
- Standard 12-Inch Formatting: Supplied in versatile 304mm (12-inch) lengths and a comprehensive range of profiles—from delicate 1/4in squares to robust 1/2 x 1in sections—to suit a variety of scale aircraft and marine models.
