This hardened steel dapping block precisely shapes hemispherical domes in non-ferrous metals for intricate jewellery designs.

What it does

Utilising a series of accurately machined hemispherical cavities, this block allows you to form smooth, consistent domes by striking softened metal sheet with a dapping punch. The solid, 3x3 inch cube design offers exceptional stability on your workbench, preventing unwanted movement during use. Its hardened steel construction ensures the cavities maintain their precise shape and integrity, even with repeated, forceful strikes, guaranteeing repeatable results for your metal shaping projects.

How to use it

  • Select a cavity slightly larger than your desired dome size.
  • Place softened metal into the cavity and strike with a dapping punch.
  • Clean block after use to prevent residue buildup.

Who it's for

An indispensable tool for UK bench jewellers, silversmiths, and metalsmiths requiring precise doming for components, bezels, or decorative elements. This block replaces the need for multiple individual dapping punches and blocks, streamlining your workflow and offering a comprehensive solution for both apprentice and seasoned professionals working with silver, copper, or brass.

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.
