Master dome-forming with this hardened steel dapping block, essential for shaping precise half-spheres in sheet metal jewellery.

What it does

This substantial dapping block precisely shapes sheet metal into perfect half-spheres. Its 27 graduated cavities, machined from solid hardened steel, ensure dimensional stability and resist deformation under repeated hammer strikes. The meticulously polished cavity surfaces allow for smooth metal flow, creating clean dome profiles that are crucial for consistent results when working with precious and base metals alike.

How to use it

  • Select the appropriate punch size.
  • Place metal over the cavity and strike with a dapping punch.
  • Clean block after use to maintain its finish.

Who it's for

An indispensable workhorse for UK bench jewellers and silversmiths undertaking production work. This block streamlines the process of creating consistent domes, replacing multiple smaller blocks or time-consuming hand-forming techniques. Ideal for intermediate to professional makers requiring a wide range of repeatable dome sizes.

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.
