the "ratcheting method" doesnt mess anything up after doing this a lot?
It may. or then again, may not. I have never tired it... myself.
But due the atty's and mod's 510 being similar if the not the same in hardness, if you're distorting the mod's threading there is a good chance deformation is taking place on the atty as well.
Personally I wouldn't try it on a Poldy, but whatever works.
If you do use a die or tap to cut threads, for gods sake, please clean the chip out of the threads before screwing onto a device. A fiberglass pen brush and/or shop air or canned air would be fine.
Having been there myself, that's my spiel on threading issues.

All three tubes plus all 350 tubes. I think I have a problem..
