Doming a star with round tools is a compromise; this block is cut for the job. Seven graduated 5-pointed star cavities let you take a flat blank and give it depth, moving down the sizes until the profile suits the piece — the same principle as our dapping and doming guide describes, applied to a shaped cavity.

Because the block is machined from solid wood there is no metal-on-metal contact to print tool marks into copper or silver, so even pre-finished blanks come through clean. The cavities sit in two rows for quick size selection, and the block asks for nothing more than a dry shelf between uses.

  • Features seven 5-pointed star cavities in a range of graduated sizes.
  • Machined from a solid wood block to prevent marring on non-ferrous metals.
  • Forms clean, consistent star profiles in sheet metal without metal-on-metal contact.
  • Arranged in two rows for clear size selection at the bench.
  • UK-stocked; we aim to dispatch orders placed before 2pm UK time, Monday to Friday, the same working day.

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.
