Not building exactly but what i did today. I have a fabricating project coming up and I've not had a torch in my hands for a month or more so felt that i needed to practice. #54 is the first two attempts, the tube with the two stubs was first, the single joint one was next. #55 had piece 3 and 4 with the tube with 4 stubs being the last attempt. While my first practice piece is OK it's nice to see results improving as i went long. #56 shows the internal flow on the 3rd tube. I'll do this again after i have the project all mitered and ready but before it gets brazed up. Andy.
