I dosent look like you had the fittings hot enough. They should be a dull to bright cherry red before you put the braze rod to them. The fittings should be hot enough to melt the braze, it should not be the flame that melts it.
When pressure testing with vaccum you only are using 14.7psi to test with. Vaccum testing should not take the place of pressure testing.
You also need a micron gauge to do the vacuum correctly. Not a must have but pretty close IMO.
Looks pretty good so far.
I did not know that you went to the chiller section, I dont usually cruise the wet side.
