Universal Fit Double Sheave Block (2.0 mm) wood detailing kit (Master Korabel BL02020)

What Is It?

The Double Sheave Block Wooden Set by Master Korabel is a meticulously crafted set of miniature rigging blocks, scaled at just 2.0 mm in size. Each block features two internal pulleys (sheaves), allowing model shipbuilders to accurately replicate complex pulley systems used aboard real sailing ships. With 10 pieces per set, these blocks are essential components for creating dual-line mechanical systems in your model's rigging plan. Manufactured from precision laser-cut wood, they are designed to deliver both historical accuracy and mechanical realism in tight or small-scale rigging configurations. The double sheave design allows for more advanced and functional rigging, such as compound tackles and counterweight systems, ideal for lifting heavy components or manipulating multiple lines through one point of contact. Historically, double sheave blocks were crucial elements aboard naval and merchant sailing ships from the 17th through 19th centuries. Their function was to maximize mechanical advantage by guiding two separate ropes through a single compact block—streamlining deck operations and improving load distribution. These blocks were used in everything from raising sails and lowering boats to maneuvering artillery and shifting cargo. Modelers now recreate those same mechanical feats in miniature, using blocks like the BL02020 to deliver realistic tensioning, line routing, and layout within confined spaces. Their inclusion not only enhances the physical integrity of a model’s rigging but also delivers a level of authenticity that reflects the real engineering marvels of historical shipbuilding.

Historical Background

From the bustling decks of 18th-century frigates to the mighty warships of the Napoleonic era, double sheave blocks were the unsung heroes of sailing operations. These dual-pulley devices allowed two lines to be routed through a single block body, creating a compact yet powerful mechanical system capable of hoisting sails, moving cannons, and controlling yardarms. Their design helped distribute loads evenly across the rigging, reducing wear on ropes and easing the burden on sailors working high aloft or deep in the ship’s hold. As naval technology advanced, the sophistication of block-and-tackle systems evolved in tandem, with double sheave blocks becoming staples in any sailing ship's inventory. Today, historical modelers reproduce these intricate systems on a dramatically smaller scale. This set from Master Korabel allows artisans to capture the nuance of this rigging hardware in remarkable detail. Especially useful in tight spaces or on smaller-scale models, these 2.0 mm blocks deliver mechanical authenticity and visual realism to any shipbuilding project. Their use not only enhances historical fidelity but also enriches the storytelling capacity of the model—revealing how every line, block, and tackle played a part in the daily life of sailors and the success of their voyages.

How to Use

1. Identify mounting points: Refer to your model’s rigging plan to locate where the single sheave blocks are required (typically on masts, yards, or deck structures).
2. Prepare the block: If necessary, lightly sand the block to remove any imperfections and ensure smooth edges.
3. Attach the block: Secure the block to the model using fine thread or wire, simulating the strop used in actual ships. Ensure it is firmly in place and aligned correctly.
4. Thread the rigging line: Pass the rigging line through the sheave groove, following your model's rigging plan for accurate placement.
5. Secure the line: Tie off the rigging line as required, using appropriate knots to maintain tension and authenticity.
6. Finish and detail: Optionally, apply stain or paint to match your model’s appearance, enhancing the visual realism of the rigging system.
