Universal Fit Double Sheave Block (2.5 mm) wood detailing kit Set (Master Korabel BL02025)

What Is It?

The Double Sheave Block Wooden Set by Master Korabel is a precision-engineered rigging component designed for scale model shipbuilders who demand both historical accuracy and fine craftsmanship. Each block in this set features two internal sheaves (pulleys), allowing for the redirection and division of multiple lines or ropes within a single compact housing. Measuring just 2.5 mm, these miniature wooden blocks are ideal for smaller-scale vessels, intricate rigging configurations, or areas where space is limited but realism is essential. The set includes 10 wooden pieces that can be easily integrated into a wide range of rigging systems found aboard historical sailing ships. Double sheave blocks played a vital role in the working rigging of traditional sailing ships, especially from the 17th to 19th centuries. Their design enabled sailors to route two lines through a single block—maximizing efficiency, saving space, and reducing friction. These blocks were commonly found in complex tackle systems used for sail control, cargo handling, and lifting heavy gear. On deck and aloft, they served as indispensable tools for crew members managing everything from lowering boats to hoisting yards. In model shipbuilding, they allow for faithful reproduction of those same rigging systems. The blocks are particularly suited for use in small brigs, sloops, cutters, and scale naval models where refined detail and dual-line rigging setups are crucial.

Historical Background

Double sheave blocks emerged as vital rigging tools during the age of sail, particularly as shipbuilders and naval architects began designing larger vessels with more complex sail plans. These blocks, featuring two parallel pulleys, allowed for multiple lines to be guided through a single housing, making them essential to mechanical advantage systems aboard warships, merchantmen, and coastal craft. They were especially valuable in gun tackle, where synchronized control of heavy cannons required strong, dual-line configurations. In practical application, double sheave blocks could be seen on both upper and lower decks—serving functions from sail trim adjustments to anchor lifts. Their versatility helped crews perform labor-intensive tasks more efficiently while reducing crew fatigue during long voyages or battle maneuvers. In scale modeling, these blocks provide an opportunity to accurately portray the layered complexity of real-world rigging systems. This set captures this tradition in miniature form, offering a historically informed and structurally sound solution for model shipbuilders dedicated to authenticity.

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.
