]Hey there everyone have been working on this 4" bubbler for a few months now, working when I can with what I have. I have done a lot of waiting for copper to arrive at the scrapers, mainly 5/8" was the hardest to come across. Anyway lets get on with it, I know every one knows what a pile of copper looks like so I going to skip them photos (because I didn't take them) and get straight in to building my modules, so I cut the 4" at work on the cold saw into 122mm sections x4. My plan at the time was to do an easy flange on both ends but some of that thread got lost in translation, had I read the thread again I would have realised that 6mm is enough to fold over because the 1/4 once flattened comes perfectly to size but I didn't listen (which has happened a few times though this build) so I ended up doing 8mm -10mm folds which was fine because at the time I decided that you didn't need to do easy flanges as it would be strong enough with out them, I still believe this but when you get the 4" clamps all that goes out the window as they will not clamp down at all and you can move the modules up and down....lol
More to come hold on a moment.
