Final Approach
Yesterday, I had to fabricate a fuel vent line for the Beech 18 and the boss handed me a piece of 3/8 tubing that that he had bought from Spruce for another project. He warned me that it was not flaring properly in that I would need to heat it up while I was flaring it to prevent cracking. I I figured I would give it a try first and sure enough it cracked. The flare on the right in the picture was the one he did and the one on the left was the one I did without heating it. It's 2024-T3 which should flare properly, correct? Spruce does have a couple softer annealed 5052-O and 6061-O but I think this one should have worked? Any ideas?
