I need to make a dozen 37 degree flares in 1/8 stanless line for a
brake system. My flaring tool only goes to 3/16. Spruce has the
"Rolo-flare" tool that goes to 1/8" for $80 or so, but they say it's
not for use with stainless. OTOH, the other vendors that carry the
Rolo-flare don't say anything about stainless. Has anyone used it for
this?

Spruce also has a 1/8" flaring kit for $19, that comes with a flaring
"punch" http://www.aircraftspruce.com/catalo...aringblock.php
is it used with a hammer?

Spruce also has Weatherhead flaring tools that go to 1/8 for SS, but
they're $400. I hate to buy one for so few jobs. Anyone got a used
one for sale, rent or borrowing?
