!! Very important !!

Don't forget to prep the outside diameter (O.D.) of the tubing end! Take a file and quickly file in a diagonal movement around the end of the tube while twirling it in your fingers. This is crucial in order to prevent cracking of the tube end when you are doing the second flare. Sharp edges crack way before smooth round edges right? Right! So that's why we need to smooth off the edges of the O.D. with a fine file really quick.
