Abstract
A generally solid block or like component having a tool engaging recess is manufactured in apparatus comprising a mould box 50, recess forming means 54 for forming a recess in a face of the block formed in the mould box and tamping means 53, the arrangement being such that tamping of a composition in the mould box is effected by the tamping means independently of the recess forming means. The recess forming means comprise projections 54 on a base plate, arcs suspended in the mould cavities or passed through the mould box walls, or cores telescoping through the tamping heads. <IMAGE>
