(fig 32) are available to cut American Standard Pipe Threads. They are held in
ordinary or ratchet-type die-stock. The jaws of the dies are adjusted by means of
setscrews. An adjustable guide serves to keep the pipe in alinement with respect
to the dies. The smooth jaws of the guide are adjusted by means of a cam plate; a
thumbscrew locks the jaws firmly in the desired position (fig 34). Non-ratchet-
type diestock and plain guides are also available for pipe threading (fig 35).
