Problem getting CO2?

[jamesb]

Here's something I picked up somewhere else.

I have been having trouble finding a suitable C02 source in my area ( south east England). What I have done is buy a 2kg fire extinguisher, taken the horn off and attatched a co2 regulator which is the same fitting!! Then I taped the trigger handle together, set the regulator and hey presto a c02 set up for my 3 cornies for less than £40.00. Then I just get the local extinguisher guy to fill it up for £7.00 Bargain!!!!

Cor he's expensive my guy that fills my welding co2 charges £3, Were cheap upnorth! but fire extinguisher guys are the best for co2 top ups! Even fill pub bottles.

CO2 fire extinguishers have a long dip tupe and are designed to vent liquid CO2 very quickly, do not use them unless this dip tube has been modified/removed.

You would not consider using a pub gas cylinder inverted would you? Same difference, as that would get liquid CO2 into your reg.

Turn the fire extinguisher upside down ??

There's an old foam extinguisher at work being used as a doorstop. It's literally just the metal flask (nothing attached) with what looks like approx 25mm thread on the top. I think it's operating pressure is 7 bar - tested to 9 bar? Could I just find a regulator for it and fill it up (through the regulator?)

No, You need a CO2 extinguisher to do this . . . . Must admit I have my own 6.35 Cylinder and a 3Kg cylinder that I can't get filled . . . I'm thinking of going down the fire extinguisher rout again myself . . . just for the fish tank . . . . I can't get a 6.35 in the lounge . . . She would notice
