How to thread black pipe with an automatic threader
Get measurement of piece you need. Lets say face to face of a 90 is 10 inches. ( I’ll cut ~11 inches for the threads )
Cut piece with a bandsaw or with a handheld pipe cutter
Insert piece into a pipe vise and secure.
Spray cutting oil onto end of pipe for lubrication
Insert end of threader
put hand on threader for back pressure
pull the trigger so the wheel is spinning clockwise
Continually spray cutting oil onto the pipe through the die (the die is the piece that comes out and can determinate the pipe size. 1/2 pipe so a 1/2 pipe die.)
Thread in ~3/4 of an inch onto the pipe and remove the threader.
