BLOCK

While working on the «Petrovsky Dock Project, ” I learned about the existence of a procedural element in maritime affairs and ship repair called a keelson block. Its concise form inspired me to create the press-paste „KEELSON BLOCK, ” which serves as a souvenir for visitors to Kronstadt and the Petrovsky Dock, specifically.

Material // Gray cast iron, Grade SCh20, GOST 1412-85.

Construction // Fully cast. Exterior bevels are executed according to the model; internal joints include radii necessary for high-quality casting.

Surface Treatment // Decorative chemical patination (red rust patina) + protective finish in the form of a transparent matte coating

Dimensions (in mm) // 100×60×70 (see dimensional drawings for details)

Note: Drawings are included in the set of production files

Production Plan:

1 // Produce tooling and a sand mold from the 3D model
2 // Cast a solid part from gray cast iron Fe20
3 // After cooling, remove the risers (auxiliary elements), clean the surface, and treat the supports
4 // Apply patination, dry, and cover with a matte protective lacquer

Shipping—in an individual cardboard box with cushioning paper filler. Kraft excelsior is placed beneath and around the product to restrict movement and protect against mechanical damage.
