I wanna see someone braze a 1 5/8 inch copper pipe with an air/acetylene rig so I can laugh at them 5 mins after they start, take a nap, wake up, and laugh some more.
Not literally, I couldn't do that. I would watch for 5 minutes then say stop, stop, stop, and grab my oxy/ace torch and say here.
(FYI I replaced a compressor on a PCA at the airport tonight. Suction line is 1 5/8 inch copper, discharge line is 1 inch. Unit is factory charge to 75 Lbs R-22. My Appion TEZ8 and Megaflow speed kit sucked it down to 378 microns in 1 1/2 hours. God, I love that vacuum set.)
If you're too "open" minded, your brains will fall out.
Artificial intelligence is no match for natural stupidity.
