sphere regasser

.................and now for the good news.
Just had a call from my mate the retired engineer advising that the recharger he has that has served him well for years, has just been made redundant due to BOC/CIG/ICI having changed the fittings that they have on their bottles of Nitro and have had for years and which apparently can't be adapted to the older style.
This change came in around last October and will cause some major redesign work.
Typical of that bloody crew!!!

Surely you can get some sort of adapter, or make one at least. How difficult can it be?

Wouldn't only the bottle connector be different (how could it possibly be anything else). Give it .... say 5seconds, and someone with a lathe will be making up 'new to old' adapters [}:)] [}:)] (that will no doubt be illegal[V]).

Guys,
I've been thinking about a regasser and how one could possibly be made without a lathe.
Do you think this is feasable.
Take one Citroen suspension cylinder. They have a bore and piston. To the piston attach something that will grab the filler plug. Put a new 'O'ring seal on the piston so gas will not leak past it.
-To loosen/tighten the filler plug rotate the piston
-Clamp the top of the cylinder that the sphere usually screws onto to the top of the sphere (using a standard square section sphere seal).
-Where the high pressure line connects drill/tap a fitting that will allow the nitro bottle to attach.
The more I think about this, the more I think it may just work. I'll have to pull a suspension cylinder off a car and see. Talk about simple.
seeya,
Shane L.

I haven't been up to see it yet as I'm sheppherding a young fellow in a CX (that a "specialist" just spent $1500 on)up the Coast as it looks like it's going to be battling to get here, but from all accounts, it has something to do with the way the regulator fits and nobody half sane plays with nitro without a regulator. Apparetly one oas a fitting that has an "O" ring whilst the new one has a taper and added to it a second portion with all kinds of gizmos attached. It's been described to me as looking "very agricultural"
I'll let you know what the story is when I see it.
There is an adaptor and it costs a lot for what it is and then they reckon it needs a different regulator (don't ask me why) and it's a further $500. Typical change for changes sake (plus extra dosh for the different bits as a bomus).

Maybe I'm not following your description correctly, but wouldn't the piston shoot out of the cylinder under gas pressure?

Brass tapered fittings are very common, in fact its the fittings with O rings that are unusual. Maybe BOC or whoever were using some proprietry O ring fitting and they've decided to give up on it and go with something more standard.
I can't see you needing a new regulator, somebody somewhere will make an adapter, if BOC has changed bottle fittings it would mean a lot of equipment would have to be thrown away, somebody will start making one if there isn't already somebody doing it.

Yep, you would weld a threaded bolt to the end of it so it could be wound in and out, in this way you could access the attachment that holds the filler plug.
It might not even work, but it will intersting to whip out a suspension cylinder and see how close they are.

Thought I'd add my twopennyworth on this one. I built this rig about 15 years ago and its still going strong:

Its not rocket science but then you do need access to some metalworking tools.
Hope this helps anyone thinking of making their own.

That regasser is nice !! I'm thinking if I could somehow use a tiny drill chuck to grab the filler plug ( getting around the different filler plugs used on Xantias/BXs/DS's/CX's).
I'm not sure if I'll ever make one, but it will sure be interesting to try.

Hi Guys,
Just a quick question to those of you that have re-gassers. Do you use a regulator off the bottle ?? The reason I ask is to get a regulator that will allow presures upto nearly 75bar will cost $600+++aud :EEK:. I imagine due to the high pressures required, and rediculous price of regulators you guys must be jump straight from bottle - gasser through a ball valve of some sort.

Shane,
No chance without a regulator and downright dangerous. The storage pressure in the bottle is 230bar. A ball valve would never be able to control the pressure. You wouldn't want to overshoot.
My regulator goes up to a maximum of 170 bar. Got it when I used to work in the Semiconductor industry. Didn't pay for it so I've no idea how much they cost.

Thanks noz,
no way would it work with 270bar. I tried to get this information from the local gas guy, he was completely unsure. Infact he couldn't find a regulator that went about 75bar.
Hmm, I'll keep an eye out, but no doubt I will not bother if a regulator is close to 250pounds[:0] [:0]
