Description
The J Perkins 1/2 X 1/2 Engine Bearer, part number 5521222, is a spruce engine bearer with a 1/2 x 1/2in profile and a 12in length. It provides a solid, straight mounting surface for engine feet and firewalls in model powertrains, helping maintain alignment between the engine, propeller and drive shaft.
Made from spruce, this wooden bearer combines low weight with the stiffness required for model construction. Its long, straight grain helps resist movement and dampens the high-frequency vibration produced by internal combustion engines, helping reduce fatigue through the surrounding airframe. The 1/2 x 1/2in section is suited to model-building applications where a compact structural support is required.
The bearer can be cut, drilled and shaped with standard hobby tools, allowing the length and mounting arrangement to be adjusted for the intended engine installation or thrust line. It is supplied in a brown wood finish and can be used as part of model aircraft or marine model construction where a spruce engine bearer is specified.
Features
This 12in engine bearer forms a stable interface between an engine mount and the model structure. The straight-grained spruce is workable for custom installation, while its rigidity supports accurate mounting and helps manage engine vibration. The stated length is suitable for cutting to the required arrangement during construction.

Specifications
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 1/2 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.
