    I have put cool gell, wrapped them in a wet rag at the same time, then spray fire ice shield on different components that I don't want to burn (be shure you don't spray the joint you are going to braze) and with oxy acetylene. If you spend a couple bucks you can get a variety of tips for an oxy acetylene setup that can get you into some tight spots. Doing this I have been able to braze up all my joints. If I have a hard time and think I have put to much heat I will stop in a heart beat cool it off and have a 5 gallon bucket half full with water or more with plenty of rags. I will change rags or rewet as needed. People have gotten on my case for burning things in the unit other than what I was there for. Now I make it a point to not only braze in the expansion valve but I will rap stuff in rags to burn less stuff other than the expansion valve. Hope this helps.

    Then you ain't looking or ya doing new start up all the time. Heads fail, saets wear out on older units and don't forget about that magical mystery oil Copeland had a few years ago.

    Cessna had ashtrays for the pilots and a window you could crack.

    Every instructor I had were chain smokers, guess it comes from that first student landing before they sign you off for your solo

    I remember my first solo, everything was cool until I realized I was the only one in the cabin and I had to land it

    And I really remember my first total instrument landing, glide slope and locator perfect, outer marked perfect, middle marker perfect inner marker perfect still couldn't see the RAIL, tower **** this, I am going around.

    My balls grew the next time (I was running a little low on fuel) and I did it perfect, but wanted to kiss the ground when I got out of the Skychicken

    After that they were a snap

    Must be using Danfoss valves exclusively. A Danfoss rep told me their failure rate is one in ten million.

    I think he meant, he hadn’t caused a failure from overheating while brazing.

    Wrap a rag around anything you don't want heated, keep the rag wet and work quickly. Why bother with anything more than that? :dunno:

    As for the bewbies a few pages back. Wrap a rubber around anything you don't want itching, keep the rubber wet and work quickly. Why bother with anything more than that? :dunno:

    Don’t forget to add some solder at the end when it’s hot enough :D

    Control the heat while you add more rod. Cool her down with some water when finished. She may smoke a little at this point but it's ok. Just let her smoke till she cools off.:cool:
