Amazing, how do you go about designing a thing like that?
Do you buy in a load of right angle bends and just tack it together until it fits?
What doe it go on
Nice job, well done, some tricky gaps to get the torch in by the look of it, a touch of pickling paste would finish it off and passivate the welds.
how long from start to finish
having seen norris`s various ones in action (providing he doesnt crash) they are a very very capable power plant...
I would try to seal pipes to flanges with an internal weld, assuring i had a tight pipe fit inside the flange. You may get away with flange warping that way and avoi cracks around the outer weld.
