Sometimes I have to thread pipe. Lately I've been collecting Ridgid drophead
pipe threaders. A few of the ones I've scrounged had real bad dies installed,
and I got some replacements on ebay and had some "issues" putting them in. I did
some research and found the correct procedure and wrote it up, like I always do.
It might help one of you out someday:
