[AT] Spam> OT: Hand threading steel pipe

[K7jdj at aol.com]

OK boys and girls,

I occasionally get  involved in projects that require hand threading 1/2 
inch through 1 inch   black iron pipe.  Lately I have been having trouble with 
the threads being  damaged.  I bought new cutters for my 3/4 inch die but 
still  having trouble.  The threads seem to get damaged toward the end of the 
 cutting process.  I try to get the shavings and chips removed and back off 
 the cutter to "break" the chips loose but continue to have poor threads.  
I  use dark cutting oil and lots of air to clean the cutter.  Any  
suggestions?  A local plumber said it was mostly the "import" pipe and that  hand 
cutting is difficult because of the lack of continuous motion when using a  
ratchet type of cutter.
