take any bets on if he destroys the seals in the vapor line service valve??
He ain't gonna do it right, he's gonna do it as cheap as he *thinks* he can
get by with.
This is from an e-mail that he sent me along with my reply:
>>> I noticed this tape kind of punctures& rips easily, I am not sure what
there is a reason I told you to use tin...not ductboard. Along with
attachment issues, you can plan on replacing the ductboard in 10 years when
it falls apart. Its not just about price.
Well Steve! guess what the HVAC tech came today and did the brazing,
you can take all the bets you want, you may be a HVAC tech, but I say we
take some bets you are off the wall, I chose ductboard because it is
something I can work with, cheap has nothing to do with it, I enjoy
doing things myself, it is my nature, I built my own home, I enjoyed
building it. I installed my 98% high efficiency gas boiler myself, and
has people say what a nice job, I asked some questions and you look for
a weakness in someone, take a hike......
Chet, Good tin ductwork is factory built except for custom stuff.
It can be purchased reasonably at any Lowes, Home Depot or Menards.
I am one contractor that looks at the durability and fire and smoke
control of using metal ducting. I can safely install Humidifiers,
Zone dampers, fire dampers, Zone air purifiers and a dozen other items
safely and very securely to metal ductwork. While codes allow fibre
board..It is far from being what an astute contractor that values your
health and safety would install. I am happy that you like doing your own
work. When your child needs Neurosurgery, I do hope the folks in that
Newsgroup can direct you to the easiest and cheapest DIYS methodology.
If not..Do keep Stormy's Email address. He may have some more advice for
you along those lines. It is said that God protects Fools and Drunks.
For you sake, I would wish that to be true.
Fortunately. Mormons who live the word of wisdom
have other divine protections. (The word of Wisdom
among other directions prohibits drinking alcohol
or hot drinks, at that time being tea and coffee).
Being half fast also cuts down on traffic tickets.
Some fellows just have to pay the highest price in education to save a
dime. Mapp gas is OK for an emergency if you know how to handle it for
light work. Average AC brazing is best done quickly and with Silver Phos
Oxy-acetylene. don't forget to trickle nitrogen to prevent oxidation
scale in the system. We keep Stormy here to give Home owners a handicap.
The rest of us make a great deal of money repairing these messes.
I've used Mapp for silver brazing, and also for Sta-Brite.
Years ago, I bought a pound of 15% silver brazing stick,
which worked well. When that ran out, I got a pound of much
cheaper stuff, that didn't work as well.

Mapp is fine for silver solder such as Staybright but not hot enough for
brazing. Yes, you can braze with it but you will grossly overheat the
copper with the length of time you need to get joints up to temperature.
