Haha no your right just the 1/16th filler I have is to much for this 16g I think, would cool down the puddle every time I added filler, prob .45 would be better for this stuff. And I did cut the pipe in to sections with my MSC bandsaw but just made sure fitment was perfect, some spots I had to use filler due to bad fitment, but overall taking my time to ensure proper fitment ment that I could just fusion weld and believe me it's strong
I have a lot more to learn but progressing every day
