Description
The J Perkins 3/8 x 3/8 Engine Bearer, part number 5521215, is a spruce engine bearer supplied in a 305mm (12in) length. It provides a solid mounting surface for engine feet and firewalls in model powertrain construction, helping maintain alignment between the engine, propeller and drive shaft.
Features
Made from spruce, this engine bearer combines low weight with stiffness and strength. Its long, straight grain structure helps resist the high-frequency vibration produced by internal combustion engines, while supporting the surrounding airframe against fatigue damage. The 3/8 x 3/8in profile is suitable for projects requiring this specified bearer size.
Spruce can be cut, drilled and shaped using standard hobby tools, allowing the bearer to be adjusted for an engine mount or thrust line. The 12in length provides material for positioning and construction work, while the brown wood finish suits traditional model-building applications. The bearer is also available in a range of other profiles, but this product is the 3/8 x 3/8in version.

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 3/8 X 3/8 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.
