Patterns for Brake Lines

One more time around on this brake stuff. I have the Eastwood Brake Tool and love it. What do I use for a pattern so I can remake the brake line from the L/F wheel to the Brake Warning Switch? A coat hanger is a good start but their must be something better. People talk about a welders rod of some sort. I am not familiar with this.

What do the MOPAR home garage mechanics use for a pattern before bending 3/16 in brake line with tube benders and use of the Eastwood Flaring Tool ??

Thx MOPAR guys and gals. I have a 1968 Dodge Dart 270 SL-6 almost ready for the road but now developed leaks because of poor brake flares (long story....don't ask).

Have a great day, stay safe, stay healthy.

Love MOPAR. Your recommendations please and past experience greatly appreciated.
