flare tool for Hynautic steering

I have not posted to the list in so long! Hello folks! I just trailered my
26 Tollycraft from Minnesota to Portland, OR and am trying to get her
seaworthy after several years of neglect on the hard in Minnesota. I bought
this boat about 15 years ago when she was 15 years old. I have not invested
the necessary $ to keep her in top notch condition and things have slowly
deteriorated, as they will. As long as I was boating near home on the
Mississippi, it was not much a problem if reliability was less than
optimal, but now that I will be on the Pacific coast, I need to bring
things up to snuff. The current task is the hydraulic steering. I had a
fluid leak at the lower helm and decided to rebuild both helms, flush and
refill the system and see. I have a three line Hynautic system. The
rebuilds were easy and getting the system back together straightforward. I
still have a leak however and need to redo the flare connection on the
starboard line on the lower helm. That may have been all I needed in the
first place!

I am wondering what type of flare tool I need and how much I should pay for
a set to do it right. Prices are all over the place. How do I know what
degree flare I need. Is it a simple flare, or something more complicated?
The copper attaches to a brass fitting attached to the helm. Are the 45
degree standard? How do I know. I may well do more hydraulic work in the
future and would not mind springing for a quality tool.

Thanks for any help.

I'm relatively certain that your fittings will be standard 45 deg.
flares, the fittings are likely brass with machined (as opposed to
forged) flare nuts, with brass flare adapters threaded into the body of
the steering components. You can check the angle with a small square in
good light.

Confirmed that it's a 45, a standard flare tool will work. Having made
hundreds of flare joints in my experience, I prefer the flare tool that
uses a flare cone on an eccentric. This method rolls the flare in a
small area at a time, incrementally forming the flare until the cone
centers. It reduces the potential for a crack in the formed flare. Ridge
tool makes one, always what I had, but there are others as good. The
Ridgid tool has a release that prevents the cone from smashing and
distorting the flare. It creates a superior joint.

Keep in mind that copper work hardens, so each time you bend or form it,
it gets harder and more brittle. If you're re-doing flares, never try to
re-form one, cut it off and start over, be sure to remove any burr from
the cut, being careful to keep chips away from the work. The cut should
be square with no perceptible roll or burr. Use a tubing cutter with a
clean wheel and lubricated rollers to avoid any scarring of the surface.
If you start with a crappy piece, you can't expect anything other than
crappy results.

And -- don't forget to slide the flare nut on before you form the
flare!  You might also want to use new flare nuts, if it's a problem
joint, you could use a forged nut, it's heavier and won't distort as
quickly, but probably not necessary.

As far as using the tool on other hydraulic work, those flares are
probably not 45, but most of those flares are not field formed anyway,
but use fittings that are swaged to hose, so not really an issue with a
flaring tool.
