Interesting to note your success with pipes that did touch. I just did
a little more tweaking. I got them closer to level, and about a 1/4"
gap.
The pipes in the images are short, but I will be welding on another 90
degree to each, then of course, the rest of the exhaust system. I
didn't make that clear in my first post.
And speaking of "secure", I'll be incorporating a flex joint and will
brace the muffler to engine. Even so, I am glad I'll be getting a pro
to do the welds at flange. --- ;^)
Anyone know if I can tack weld these in place before taking them to the welder?
I imagine he would do his own tacks, grind off mine, then weld. But
I'm not sure of that.
Neil.
