I am in the process of restoring a Lotus 69 formula ford. The car has lots of British fittings which I am thinking about switching over to AN. I need to buy/rent a flaring tool for the hard brake lines and I have been told I MUST double flare the ends. However, it seems that there are almost no double flaring 37 degree tools - only 45 degree tools.
Aircraftspruce have one VERY expensive tool for doing 37 degree double flares but it is designed for copper/aluminum tubes and not the Bundy (mild steel) tubes I need to use.
Does anybody double flare their 37 degree AN hard brake line ends? If so, what tool have you used to do so?
Please advise....Keith
