Description

Sinking is a process used to create flat, shallow tray shapes (i.e. Flatware) by beating an Annealed sheet metal shape into a recess formed in the end grain of a suitable block of close-grained Hardwood known as a Sinking Block.


Features and Uses

Sinking Blocks are usually self-made as required with removable pegs to maintain a constant width of rim where needed. A suitable manufacturing procedure is shown below:

  • first, a block of close-grained Hardwood is drilled through towards one end with a drill diameter twice the required recess depth (e.g. using Forstener Bits);
  • then the waste is removed to reveal the required 'step'.
  • Removable pegs are added to complete the block ready for Sinking.
