I owned and operated muffler shops for 30 years. I am pretty comfortable welding thin tube, rusty tube and filling gaps with a MIG. My major malfunction is that I always had a big, heavy hydraulic exhaust pipe bender standing in the middle of the shop. All I had to do was hold the pipe in front of the jaws and press my knee on the paddle switch until it was bent far enough. It was so simple, I am now unable to fathom how to use this Harbor Freight hydraulic jack with a couple of rollers and different size pipe shoes. Fabricating stuff without being able to bend the pipes to clear components makes me feel really stupid after becoming quite good at bending pipe to fit under , basically, anything.
nightgrider: if you have a reciprocating saw or a grinder, you COULD leave you component round, mark it and either just hold the end of it to your grinding wheel for a while, then roll it over and hit the other side. Best tubing notcher I ere used. My preferred quick method is to fit my parts together, mark the end of the pipe right where it touches the side of the other pipe, then just saw a couple of half-moons out of it. Weld'em up.
