The normal length of tapered thread on a 1" pipe is about 1" long. If you keep threading farther,all thread will be NPS (1"-14NP),except the innermost 1" or so.
I do this with alum. pipe for ant. mounts,but you could use SS pipe.
Another method is buy a 1"-14thd NF bolt & cut to length you want.
Hi Len, thanks for the tips. I am just really surprised that the local shop doing the fabrication of adding an additional branch to my radar mast
does not have the die to create a straight thread on a short section of pipe. I then started calling the various West Marine
Stores (worse than useless and their new call holding music
makes me want to go postal) and a few other marine supply stores in San Diego
and got no where. It is getting bad trying to find boat hardware
and even worse trying to find store staff that have a clue.
