Checking Thread Length and Depth

(See Figure 29.)
1. Thread is cut to proper length when end of pipe is
flush with edge of dies (A, Figure 29).
2. Die head is adjustable to obtain proper thread di-
ameter. If possible, threads should be checked with a
thread ring gage (B, Figure 29). A proper thread is cut
when end of pipe is plus or minus one turn of being
flush with face of ring gage.
NOTE! If a ring gage is not available, a fitting can be used.
This fitting should be representative of those being
used on the job. The pipe thread should be cut to ob-
tain 2 or 3 turns hand tight engagement with fitting.
If pipe thread is not proper diameter the index line
should be moved in the OVER or UNDER size mark
on size bar. (refer to installing dies in die heads).
NOTE! Receding dies used in 714/914 Head are NOT full
width dies!
