Hello... Go to a yard and ask them to hang a 12" diameter by say one foot in length piece of stainless pipe on your extended arm and give them instructions to hit you with hammers when you cannot hold it at a right angle to your body... Big pipe is pretty on a computer - but gravity and mass does not exist in same... Straight stack and damper box... SH.
Ha... Ha... That's why we have crane... but yes, I thought of ways to save material... you got to try to know... the pipe will be reenforce with smaller pipe and plate it to look oval.... just maybe..............................
