Hi folk`s, we didn`t have any water when we cut our bottle, we just opened the valve and left it upside down overnight, whole place was stinkin of gas, even though cylinder was empty, you could still smell it inside the cylinder 4 days after we cut it  !! Recommend that you do fill with water.
cheers
Will

Funny you should mention the smell.  I left my bottle standing, full of water, for 5 days and emptied it this afternoon.  You could still smell "gas" as the water came out.

I don't think you are smelling the gas but an extremely pungent tracer smell added to the gas so it can be detected more easily.

Does it somehow leech into the metal?  Or perhaps form a surface layer on the inside of the cylinder, that water breaks off?

Well done Keith, nice work, you did well with that degree of heat sink so close to the joint, must have had the torch running full tilt.

Great set of photos too.  A close up of one of the finished joints would just complete the set nicely.

What do you do with them, you mean after you've written the wiki page ... sell them on eaby of course, pressure tested to 12 psi with a nice photo to prove it.

Or, build a GL using them instead of a plumbers delight ... I know what a fan of the GL processor you are!

Yes, I thought true enthusiasts made all their own kit ... buying a tank is just cheque book engineering!  It's probably the shiny blue paint that appeals.

Re silver solder, You used all that on four joints!  No wonder the pressure test was ok, you've probably fill the whole HE up!

Not sure on the type you link to, it's been years since I bought any.  I still have 10 sticks left, probably quite an investment now they are 7 quid a stick.  I'll try and do some delving and see if I can find the details of what I bought originally.  I know they were pretty good because they were recommended for making boilers running at 180 psi.

There you go, found it ... it was Either Easyflo or Easyflo No 2, both by Johnson Matthey.  Easyflo has a slightly higher silver content, flows better and is more expensive.  Easyflo No 2 has less silver and hence a slightly lower melting point at around 610°C, is cheaper and will form fillets a bit better than Easyflo.

Both are ok on steel, stainless, brass and copper.  Although they recommend a different flux for steel, I've never bothered and have not had any problems.

Ha, just checked JM website and both have been discontinued because they contained Cadmium, shows how old my books are!

The replacement for Easyflow 2 is Silver-flo 55, so I'd recommend that.  Axminster do 1.5mm x 600mm for GBP 7.00 inc VAT. http://www.axminster.co.uk/johnson-matthey-silver-flo-55-silver-brazing-alloy-prod23273/?src=froogle

Might get them cheaper if you hunt around.

Pointed nose pliers were designed especially to stop you burning your fingers when silver soldering.

Pink processor ... wouldn't that be great?

Not sure about the VA, my daughter is due home some time in April after two and a half years travelling the Far East and whooping it up in Australia, so I don't want to miss the home coming.  Just can't tie her down to any dates at the moment.  If I go I'm a bit stuck for a partner, none of my mates are really into that sort of thing and any navigation by the wife culminates in a argument many miles from where we should be.  That's why I'm so fond of the lady on my satnav!

There must be a macro setting, even my second hand manky old thing will do close ups.  Try fiddling with a few buttons you haven't used previously ... always works for me!

Sounds good, I'll keep it in mind for when I know what my offspring is doing.

In fact if it's from a Vaillant similar to the one Paul posted, don't buy fittings.  I can drill out the spigots to make 15mm sockets which will take the pipe directly ...



Just let me know how long you want the pipes.


Ooooh ... I feel another wiki page coming on for the benefit of the veg community!

me and next door drilled and tapped one of the above pictures fphe and used banjo's and banjo bolts off old IP pumps + copper washers  8)

Any pictures Paul?

Could be a new page, I've got the photo you've posted plus this one on the silver soldering page here ... http://www.biopowered.co.uk/wiki/File:Silver_soldered_pipe_connections_on_a_FPHE.png  along with Keith's above might be of interest to both vegies and bio boys.
