Very nice fitting.....I am not a air balancer, but this looks like it would play havoc on your air flow ? I can see where bending time is the real thinking time here  |

| Nice job, I know what you mean about the bending part, it can be tricky. |

Well..... I woulda made it radiused! LMAO
Sweet looking fitting. I made one that was a 1/4 twist once, thankfully it didn't have to be perfect and would be hidden, it didn't turn out half that nice. |

| Pretty cool. How did you lay it out? I've made one before for a grease duct job. I believe I used a triangulaton method similar to that of a square to round. |

| It looks like a fun one to build because it's not center twisted. It appears that the upper left corner is in line...I'll think about that one on my way to work this morning. |

| This piece is like the problems my old journeyman used to set me ,he would come in on the Monday and say things like ,can you develop a cone? i would answer yes and he would then produce some obscure sketch and tell me to develop the pattern on template paper ,Iowe this man and many more through the years a big thanks for a love and passion for sheetmetal work and pattern development that has never faded with time . Yours with a lump in his throat Marky |

We went over this fitting in class tonight...
You got it right, I see two valleys there...
BTW- My Instructor, who just happens to be one of my supervisors at work, not to mention a lifelong friend, informed the entire class about this website tonight. |

| Its an absolute beauty!, though it looks to me that you might loose a little of airflow, is the best i've seen to get out of uneven areas |

| Nice looking fitting. I have a couple words of advice. If you had layed out the fitting with your break lines running counter clock wise you wouldn't need any breaks on the outside of your fitting. You could then break the whole fitting fron the inside and you wouldn't have the disruption in the airflow. I also did one of these a few months ago and the first one had the same breaks yours does. The second fitting I did I rotated the break lines and then they were all done from the inside. The fitting I did was a 45 degree twist but was also a transition from 12x6 to 17x4. It does make you think about the line breaks. I'll try to post a picture if I can so you can see where you made your mistake. The only other thing you need tyo remember is to double break your breaks twice. One time at 30 degrees and the second time at 60 degrees. |
