[Amps] Mechanical question

[mike kendall]

Colin,
    I was wondering if there is a "next size larger tubing" that will fit over it like telescoping aluminum tubing for antennas.  If there is that would be the easiest approach for sure. Possibly, if there is not an easier next size up of tubing I could get a small bit of copper and use a drill press to drill it out with the right bit then slip it over and solder.  I would have to heat it up before sliding it over to try to keep the heat stress off the cold plate.
  73,
  Mike

  Hi Mike:

Always trying to do things with the least amount of work, what about using a coupling that is simply one size larger, then solder onto both lines. That requires no swaging, only a little more solder, less expense and less work.

It has 1/8 inch copper tubing coming out of it for a couple inches and is designed to have more copper brake line soldered/brazed to it. Is there a tool that I could use to expand out the brake line a little so it will slip over the other brake line and allow a good mechanical connection before soldering?
