Thanks!
That hand drawing way of yourīs is exactly the same that I used to do (though those 20mm steps may be bit large, when doing tight corners/having rapidly expanding sections). But if something can be done with CAD softwares, it has to be done! Not only is it cool, but you can also do lots of parameters in the models, which make the needed modifications fast and easy.
Oxy-acetylene torch would be great to have, since itīd be easy to anneal those MAG welds into soft state. Somehow my propane torch isnīt powerful enough to give the sufficient amount of heat for annealing the pipe. Even though it is rated at 6kg/hr propane consumption... The annealing of the welds only would also let the sheet metal itself to stay into bit more durable state. The cracking of pipe happens at much lower pressure when the whole pipe has been annealed. But, itīs a compromise bethween the absence of wrinkles and pipeīs tendency to crack... With TIG welds there were no problems with wrinkles nor pipe cracking, and the welding itself was a pleasure as well.
Though Iīm newbie, I thought whether this topic should be renamed as "Designing and manufacturing of exhaust pipes" etc.?
