1biggun, I was curious as to how much the threads would be effected on a remington barrel if it was rethreaded to 1"-14tpi since 1-14 taps and dies are about half of what 1-16 ones are. I chucked up a section of 1.25" 4150, took a skim cut and threaded to .009" deep with the lathe set at 16tpi which would be about what is left on the remington barrel turned to 1". Then changed the threads to 1-14 and started over. This was just a quick test, so I didn't grind a new bit and just used an indexible bit which had a slight radius to the tip. You wouldn't normally use one for threading since it would leave the bottem of the "V" rounded....which it did and you can see if you click on the pic. But, we're wondering about the tops of the threads, so it works just fine. Since the tip is wider it would also increase the criss cross areas. If you look real close you can see where the old threads crossed the new. Cut with a proper bit, I don't think it's an issue.
