I bought a double flaring toolfrom on of the local auto parts places.
It has the different sized holes for the various line that who are
using. Went and bought a 3ft. piece of tubing 5/16th tubing from Napa
with the flares already formed, cut one end off and went to double
flaring, comparing my flares with the store bought ones. Some were
good some were not. Is there a secret in getting consistenly good
flares or maybe I am being to critical of my flares.

Yes you need to file / chamfer the tubing before you flare it, then
carefully set it the correct height in the tool.

It would be nice to have a tool specifically made for chamfering
steel line before double flaring, using a file doesn't always
work out well and the results give so-so uniformity...

Something sort of like chalking a pool cue if you get my drift.

Any ideas?
