Mapp-oxy (correct spelling and capitalisation?) seems to be a good
alternative to Oxyacetylene for DIY purposes (ie, heating up seized things),
but I've not got a clue where to get it. Can I get it in self sealing cans
and screw it onto a normal blowtorch head, or do I need a specially designed
setup?

Hi

I've got a Bernzomatic TS7000 torch with a MAPP cartridge on it. Cost
is around £55 from B&Q. It is superb - lights instantly first time
every time and is ridiculously hot. Easily capable of driving residual
moisture out of pipes whilst soldering.

Can you get steel glowing with it?

Never tried... I'll give it a go tomorrow if you like.

Ta. That's what's really needed for a replacement to Oxy acetylene for
undoing seized stuff on cars. Get it stinking hot quick sharp and near
enough anything will undo.

Around £30 or less on ebay +P&P.

It's a lousy alternative to oxy-acetylene (can't weld with it), but
it's a tolerable substitute for oxy-propane that doesn't involve
rental on an oxy cylinder. OTOH, burners are cheap (eBay!) and simply
using a bigger propane-air burner often gets the job done. Personally
I don't bother, but a gunsmithing friend swears by it.

Even cheaper, are a few firebricks:

MAPP is good, but best at small stuff, where you can't otherwise
tolerate a simple huge burner. Once you've found a supplier, standard
screw-on propane or propane/butane mix disposables are all compatible
with it. I've never seen MAPP in anything bigger.

Hi

Sunday morning - what better to do than a bit of mindless playing with
fire

30 seconds to bring 10mm threaded steel bar to glowing point.

A couple of pictures he-

Don't doubt it - I just needed one *right now* one day a while ago -
you know what it's like...

Well I've fancied getting one for a while, so today I treated myself. I
saw a new Bernzomatic TS7000 torch head for £20 at a car booty and took
the plunge. Then searched around for gas and fund none, so I ended up
at B&Q. It seems the head will run on three different gas tanks, all
about the same size. (Correct me if I'm wrong -) Butane canister, blue
propane and the most expensive - a yellow tank with which you can
produce enough heat to braze at almost £14.

It has a very tightly formed flame and can certainly bring rusted steel
nuts and bolts quickly up to red heat.
