--- Quote ---Please note the qualifier "I don't need to do production threading." So long as sharp-corner v-threads are what you need, this will work fine. However, if your work is subject to inspection to any of the formal standards, you will be in a world of hurt. Each pitch has a specific radius at the root/crest (external/internal) thread that is required to qualify under formal standards. I realize that I am being pedantic here and that most here would not need to meet formal standards, but the caveat is something that should be known -- even by those who have no need of the formal standards compliance in their work. --- End quote --- Thanks Lew. I had no idea that there were standards for the radius at the root and crest. As you say, I don't need to work to standards for the things I build myself, but I will pay attention IF I ever need to make something for NASA. :lol: Peace! |
