Dear Listers, Its November 30th and that means three things:.. 1) Today I am now officially 45 years old... 2) It marks that last "official" day of this year's List Fund Raiser! 3) Its the last day I will be bugging everyone for a whole year!

They flair the tubing at a 45 deg angle. All aircraft flairs are 37.5 degrees and all of your aircraft AN- fluid fittings have 37 deg cones. Your flairs simply will not seal effectively and will eventually fail. Also never take a file to smooth out the ridges on aluminum tubing; you create small stress points where the file nicks the tubing leading to stress risers and eventually failure. It does not take much abuse of aluminum tubing to cause it to fail - I had an aircraft wheel fire due to a ruptured aluminum brake line which sprayed brake fluid on the hot rotor disc which ignited. Fortunately, a quick thinking nephew of mine found an extinguisher and put it out before serious damage occurred. Go out and buy or borrow a 37 deg aircraft flaring tube - if you belong to an EAA chapter, there are probably several members who have one and will be willing to loan it out.

I recommend getting the Harbor Freight clone of the Imperial Eastman tubing bender for doing you bends. I paid about $5 for mine (it was on sale at HF).
