I started off with a Chilly1 evap and did some prep work on it. I used a drill and made some notches around the inside of the spiral. Then I used my Dremal to made some notches where my drill wouldn't work. Next I taped the inside of the suction channel. My intention is create more turbulance inside the evap.





I made sure to clean up all the metal filings with air pressure. Then I used my wire brush to get the evap really clean. The most important thing you can do to get a good braze job is to sand all metal points that get brazed. I like to use my polishing wheel, wirebrush, and sandpaper. Also be sure to purge with an inert gas. (nitrogen)



All I ever use is my mini torch



After you braze it is important to check for leaks but I like to clean the evap first because it's easier to lap without suction line. I'm counting on no leaks because if you have a leak you have to braze again and then clean again.
