Hollowing Block
From DT Online
Description
Hollowing Blocks can be made by carving or turning concave depressions into end grain of a suitable close-grained Hardwood to create a hollow into which sheet metal can be formed with a Bossing Mallet or Blocking Hammer for example.
Features and Uses
Hollowing Blocks are often self-made as required but can also be purchased.
A similar block when Blacksmithing for example, can be made by placing a short length of suitable diameter steel tubing over an inverted convex punch (e.g. a Stake perhaps), and pouring in molten Lead to create the block.
