What a difference a day makes! (and a gas lens. I upgraded my torch to a gas lens.) The quality of weld on this "purpose made" practice piece is actually pretty darn acceptable. Everywhere has said a gas lens makes a world of difference, and I finally did it and wonder why I took so long. The bits (lens collette, 3 nozzles, the back seal) were only about $20 to upgrade my 17 style torch. I guess I figured it would be a lot more. Now I know. And you do too!
