Step one - Cut the tubing SQUARE with a fine tooth saw blade or similar,
don't use a tubing cutter as it crimps the tubing and work hardens the
cut location. Neither of those is desirable.
Step two - debur the tubing VERY well inside and out. You want it smooth
inside and a light chamfer on the edge. Install the fittings you need
THE CORRECT DIRECTION!!!
Step three - set up the tool PROPERLY. This is the step that causes
grief. Use the double flare adapter to set the tubing depth. Clamp the
tubing tight, slippage is not a good thing.
Step four - use a small dab of brake fluid as a lube on the die. Make
sure the double adapter is square on the tube when you start tightening
it down.
Step five - Tighten the tool till it bottoms out the adapter on the
frame, then open the forming die and remove the double adapter.
Step six - Run the forming die in till it seats and creates the nice
double flare you need. Remove the tool and lightly clean up any marks
the tool left on the tubing. I like to install the tube then paint it
with some good paint. It makes them last a while longer in the salt.
You can also create a bubble flare with the same tool. You just skip the
last step.
