Can you cut pipe threads off and re-thread the pipe?
I'm running blk gas pipe under my craw space and coming up through the floor to a hot water heater. I cut my last piece of pipe about a 1/2" to long for it to 90 up through the hole in the floor, I can't reposition the hole because of a tight space. Can I cut off a 1/2" of threads on the pipe to make it shorter and then re-thread the pipe again? Would my cutting die run back up the threads that would be left on the pipe after cutting it or should I just buy a new length of pipe and start all over again?

Yes you can cut new threads. It seems it would be a lot easier to buy the proper length. You can have a piece custom threaded at most Lowes or HD stores. Be sure to allow for full threading into you fittings to get the right length.

You know what they say, you can always make something shorter (pipe, 2x4, rope) it's making it longer that is tough!

Yeah it was an odd measurement so I couldn't get the right size nipple.that would fit. I never had to cut a few threads off a piece of pipe before and then run my die over the threads left on, wasn't sure if it damage the threads going back over them again. I'll try re-threading again and see if the threads look ok, if not I'll take a run to Home Depot and have them cut me one..

I would run your pipe threader on to the pipe and cut the threads before cutting the end off, should be easier than trying to start over the cut end. And if you have enough room you might be able to leave the threader on the pipe, cut off the excess pipe then run the threader off to clean up the cut end.
