I am at the point that I have to learn to flare aluminum tubes. I have searched this site for info and it seems single flare is what most builders use. I have also googled the subject and Kitfox has a bulletin for fuel lines and it does not mention double flares.
The only reference to double flares is in the Hydraulic section of 43-13, which due to the low pressure should not apply to pitot and fuel lines. I am curious what you A&Ps or IAs where taught and or what you use in practice. The double flare tools are expensive for the 37 degree variety. I wonder if you could use a 45 degree tool to turn in the tube end for a double flare then us use the 37 degree tool to make the actual flare. Any help and clarification would be helpful. I have bought the Rolo 37 degree tool from Avery and have been practicing, I made a nice flare on 3/16 tube that is used in the Dynon Pitot.
