The downside to brazing is the equipment costs and getting into the
world of bottle rental

My Uncle Tom used to tell tales of a welder known as "Arson" Pavitt
whose party trick was to allow the flame to blow back into the
bottles. At which point the cry of "Bottles!" would go up, and people
would run very fast in the general direction of Away :-)

An oxy-acetylene set can be clearly seen in the second picture here:

how hot do you need? If you are silver brazing it should be more than
adequate.

I think you need acetylene for bronze which seems to be more highly
regarded. Depending on how well the rebuild of the frame goes, I may
consider a change of plan! :-0

LOX is hilarious. Take one barbeque piled high with charcoal. Place one
lit piece of charcoal on the top. From a safe distance tip a silly
amount of LOX on top.

When the ensuing fireball disappears, your barbeque is ready for use,
although on occasions this has removed the actual barbeque leaving a
pile of charcoal (About 1/3 of the starting amount!) on the floor.

The garage cable is only a spit and a cough (with a cough being half a spit)
down but is under lots of Small Rocks along with the telewest cable (which
was almost surface mounted cos of said rocks and telewest not being too
concerned about leaking bytes into the environment.)

That may not be in conformance with BS7671, which from memory talks
about cables being deep enough not to be disturbed by normal
activities above. In the case of my shed that means being below the
level a lawn spike reaches into the ground. Were it to run under a
flower/vegetable patch it would have to be deeper, to escape double
digging.

A spit is a spades depth (honest, hence clarifying the dimensions of a
cough). For double digging it would not be deep enough but a) you cannot
double dig my front garden without a pickaxe and b) it is low enough to go
below the foundations of the new retaining walls I have been putting in.

It's actually about 18 inches down to the top of the rocks on top of the
cable.

I think this is low enough.

Possibly for bronze but that will take you well into the zone at which you
will seriously affect the properties of the steel. Silver and brass can
easily be done with oxy-propane.

Hmm. How can you be at a safe distance and tipping LO2 onto it?

My parents barbecue was a test piece for welders on a North Sea pipe laying
barge. It lives outdoors in all weathers and is readied for the seasons use
with a 9" angle grinder and stiff wire brush. The body is made of 6mm steel
and it is slightly smaller than an oil drum. We didn't use it much as it
took so much charcoal to get it going that it was only really economic if
you were feeding more than about 20-30 people.

The barbecue tools of choice were a pair of welders leather gauntlets.

D is for Dante..

Do not expect the building inspectors to agree :-)

There is an estate near here which is built on a former gravel
working. The houses are on concrete rafts and wander around the
landscape perfectly happily. If you want to build an extension,
though, it has to have 6ft deep footings, with the result that it
stays put while the house continues to wander around the landscape,
with predictable results.

Nuthin. Daughter's bf has a deeeeeep hole in the drive of his
parental abode, as his dad is building a brick porch. On account of a
row of conifers, 4 feet tall forming a hedge between his and the next
house, the building inspector has said he wants foundations 2.4m deep.
That's 8 of the BRITON'S feet, to paraphrase Mr.Larrington.

That resembles my parent's house. Which subsequently had the porch &
garage reattached to the house after they "wandered" in different
directions!

With a _very_ long stick! :-)

Sadly it appears that George Goble's web page has been removed at the
request of his university, taking with it the photos and video footage.
This is a great shame.

One of the loudest explosions I've ever witnessed was caused by an
oxy-acetylene kit and a bowl of soapy water. For those daft enough to
try this at home (Kids! Borrow your mates dad's kit instead to save
blowing up your own garage!) simply turn on the torch, dip the nozzle
under the soapy water, turn the acetylene off and the oxygen up. When
you have a suitably large amount of oxygen rich foam, turn off the
torch, don appropriate protective gear, retire to a safe distance and
apply a long taper.

Then wait for the anti-terrorist squad to show up.

The thought of Council officials checking my wiring is what amused
me about another posting. Some are very good, but many are not.

If you are tempted to recreate this at home, do remember his warning that
you put the ignition source in place _before_ pouring on the oxygen, not
soaking charcoal in liquid oxygen and then lighting it. The latter will
explode.

Relevance to your lock? don't press too hard or try to cut too much at
once.

Indeed. You also need rests because your hands will be soaking up that
vibration. They are good fun though!

I've had to restrict where I use mine now that we have a new set of
batteries for our power supply. I have to avoid the possibility of a spark
flying into the battery shed and igniting any hydrogen that's gassed out
of the batteries. That would be a little less than fun.

For the sake of the locals it is probably best that I currently have no
access to LOX.
