I decided to go with 24 ga. Snap lock HVAC ductwork for my new cyclone as there is a factory here in town and it can be bought very, very reasonably as a result. They didn't make long radius 90's so I thought I would make 45's out of two of the adjustable elbows and put the together to make a longer radius 90. I have turned the 4 segments every which way I can dream of and can't seem go get a 45. Do any of you know the trick? I've made a 30 and a 60 but just can't get the 45. I appreciate any help.
