3) Its the last day I will be bugging everyone for a whole year!

Throw away or cut off any flair you have made in aluminum tubing with the
"automobile" type flaring tube. 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.

Subject: RV-List: Brake line tubing flaring
I went down to the local hardware shop and bought their best flaring tool to
do the aluminum brake lines, is this the correct tool? the ridges it leaves
in the tubing will not let the sleeve slide up, I had to take a file and
buffer to it to get them out , I tried again same results, is there a
better tool?
and do the bending coils I saw work good?

Dan,
As others have stated, you need an aviation 37 degree flaring tool. 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). See

I am almost 99% certain that what they sold you is an automotive 45
degree flaring tool, which is the wrong one. What you need is a 37
degree aircraft flaring tool. These are available from Avery, Spruce,
and most of the other aviation industry suppliers.
