Form perfect domes and hollows in sheet metal with this hardened steel dapping block, essential for detailed jewellery fabrication.

What it does

This robust, rectangular steel block offers a stable foundation for shaping precious metals. Its precisely machined hemispherical cavities, ranging in size, allow you to gradually form domes and hollows using a dapping punch and hammer. The hardened steel construction ensures durability and resists deformation, providing consistent results across all 14 depressions for repeatable shaping without the need for mounting.

How to use it

  • Place sheet metal over your chosen cavity.
  • Gently tap with a dapping punch and hammer.
  • Wipe clean after use to maintain the finish.

Who it's for

An indispensable tool for UK-based bench jewellers, silversmiths, and metalsmiths needing to create precise domed components. It streamlines the process of forming bezels, earring backs, and decorative elements, replacing the need for multiple individual forming stakes for this specific task.

Common questions at the bench

How do I form a dome?
Anneal (soften) the metal first. Set the disc or blank on a cavity, choose a punch that fits that cavity and strike lightly while moving the punch round. Work the dome in stages through the cavities, with a punch that fits each one, until it has the depth and shape you want, annealing again if the metal becomes hard to move.
Which punch fits which cavity?
Use a punch smaller than the cavity, leaving room all round for the thickness of the metal. A punch that is too large pinches the metal against the edge of the cavity, which marks the dome and can damage the punch and the block.
Will it mark my work?
Grit, filings or scratches in a cavity or on a punch head print into the dome. Keep the cavities and punches clean and smooth, use punches that fit, and strike squarely rather than hard.
How should I look after it?
Wipe the block and punches clean after use and store them dry, where the cavities and punch heads cannot knock against other tools. Keep anything made of wood away from water and pickle.
