can someone kindly explain the proper procedure to get a good single flare for AN fittings?
I am not sure if I am doing it correctly. I have tried multiple ways, and the best results I have gotten were by setting the tube to be flush with the end of the chamfer on the die, skipping Operations 0 and 1, and going straight to Op 2. is this correct procedure? it has given me the best results, but the inside of the tube appears to not be smooth, as if it is flaking.. see pictures. the tool is brand new so the dies are in good shape.


there is nothing about single flares in the manual or online.
thanks for your help!
