ABSTRACT:
To firmly retain a jaw of a lathe or like chuck against movement it is formed with a transverse passageway or hole through it about midway of its length, a U-block is inserted in it in an inverted position so its legs will bear on the chuck face and a bolt is threaded in jaw directly above the U-block so it will bear on the block and force it against the chuck face.
