It looks like these are being discontinued. Instead one can again buy

Does anyone know the reason? Is this because people hated attaching
their torches directly to the Fat Maxs? What was the outcome of the
various lawsuits? Have they changed the cylinder construction to make
them safer?

All I know that in our local Home Hardware the 14 oz cylinder was
actually more expensive than the Fat Max (16.9 oz).

I bought two of the Fat Maxs which should last me a bit but I am
getting kind of tired of Bernzomatic chopping and changing (the new
cylinders will not fit my holder). I expect the only alternative is to
go with air/acetylene.

Has anyone here had hard time with their insurance company using
air/acetylene? I am specifically banned from "welding" within 25 feet
of the house but I am allowed to "solder".

Though the question of air/acetylene has never come up with my
insurance company I can attest to the usefulness of air/acetylene for
soldering. The flame is quite hot and makes for quick soldering jobs.
I'm surprised that propylene isn't available to you in large cylinders
like acetylene is.

I was about to suggest that he use Mapp gas. But wiki says it's been
discontinued for years. (I didn't know.. guess I should hang on to
the half bottle I've got.)
Is the propylene some inferior substitute?

MAPP is Methylated something Propylene. And it was available in bulk
and 20-pound BBQ style cylinders for a while through Welding Supply
houses and such, not sure what the current status is. If I need a
large quantity like that, Acetylene is more convenient because you can
weld with it too.

I just bought a couple 1-pound MAPP cylinders at Home Depot for a hand
torch not long ago, so it's still around. MAPP-Air gets hotter than
Propane-Air for little plumbing jobs where I don't feel like lugging a
B Acetylene.

Bernzomatic is pushing the little-baby 1/4-pound MAPP cylinders there
for hand torches, but that's stupid - they can't hold enough energy to
cover the cost of making the containers.
