I looked at the Eastwood bender again and realized it said 1.25 diameter bends instead of radius. I'd like to be able to bend the hangers I got so they wrap around the pipe a little bit. I ended up making a tool with some scrap and a short 2" steel pipe union. The outer diameter of the union is actually only 2.375" but that should be close enough for 2.5" exhaust pipe.
I'll heat the hangers up with my torch and bend them around the pipe. At least, that's the plan. We'll see if it holds up or not. I got to try out my tig skills on a real project at least instead of just test pieces. My skills are not ready for Instagram. If they hold, that's all that matters to me.
