ya, i'm welding a female in there recessed, and i'm definitely no expert, but practice makes it get better. none have broken so far, so i dont see why i should go back and learn the basics like you suggested before. i'm just gonna keep practicing recessing these. i am just getting to the point that i can do not bad seals on clear joins now. this afternoon i'm gonna try my first tenmm recess. sounds tuff.
