I'm really not great at accurate metal fabrication, especially with exhaust tubing. I'm trying to make a new down pipe for my turbo, and i need to make a dual angle cut. I've already wasted one $45 elbow, i'm trying not to waste another.
I realize this is a simple task, but what do you guys do to cut accurate angles?
Miter saw with a metal cutting blade (abrasive disk) in it.
What tools do you have available?
I'd probably saw off the expanded part, and then start slowly filing off until you have the fit you want. Then flatten the cut out with a belt sander or a piece of sandpaper taped to your bench.
I've fit up tube like this in the past, and it takes a long time but your chances of going too far are much lower.
I have a lot of old crappy exhaust pipe from former cars that needed exhausts replaced.
Lots of different angle bends. I had kept it around for impromptu repairs but found it very useful when fabling the exhaust for my current project, as I to am not a good at metal fab.
Miter saw as mentioned above. To mark the cut so that it is perpendicular to the pipe, even in the middle of a bend, cinch a zip tie around the pipe and use that as a guide to draw the line for your cut.
I forgot I owned a chop saw, I used that and was able to get it to fit pretty well. Now to figure out the rest of it, thanks for the advice!
