I also considered hacking at it and if it doesn't work, I'll call a repair company and tell them the last guy that worked on it left it that way and walked off the job. (No need to know that I was the last guy that worked on it).  |
As they told us in the Union Pipefitter Apprenticeship school, if it were easy little girls would do it. There are a few reasons why it takes 10,000 on the job hours to be a journeyman. This isn't a union vs non-union argument as there are plenty of good non-union a/c servicemen, but they didn't learn it in a weekend either. Rant over.
Practice brazing with a 15% silver brazing alloy and your oxy-acetylene flame a tiny bit rich. Its not quite as hot and its less likely to oxidize the pipe. Replace the liquid line drier while you have it open or you WILL regret it.
