Hi,
I have a pistol (Walther CPM-1) that’s needs a bulk fill of CO2
I have a 2KG CO2 Fire extinguisher on order, and will now need a hose, some sort of tap and bleed valve?
I had a quick look on the auction site and found something like what I was looking for, £16 shipped from China, I am not sure I would trust it.
Anyone point me in the right direction please.
Thanks

I fill my Crosman 400 using a fire extinguisher, very easy. The Crosman have a thread similar to 1/8 BSP. If you take the large cone off the end of a CO2 extinguisher you have a hose with 1/8 BSP male thread. I screw this into the Crosman female thread on the rifle which has a little valve in it.You just depress the extiguisher lever and it fills the chamber.It does not overfill as the pressure is about 900 lbs a sq inch at 20 deg C and just equalises out in extinguisher and rifle.You obviously may need an adaptor to take the thread on your pistol to 1/8 BSP to use this method.
Never press the lever on a fire extiguisher if it has no hose attached as the jet propulsion produced is so great it can break your wrist.

Dave,
Porkyyorky does them sometimes on the ukchineseairgun forum, I'll pm him and see if he's got any left. I'll let you know. I'm still waiting on my nipple turning up.

It never ceases to amaze me how many people on this forum do not actually read fully what is written. It is like they skim over the message.Last guy swore at me and told me I was being picky when he got the thread completely wrong.
If you read what I said "no hose attached". When you remove the fitting from the extinguisher the gas is vented direct from the non flexible valve and gives a powerful thrust.The hand you are holding the bottle in is pushed suddenly back at a sideways angle.This information was given to me by the suppliers of the extinguisher.

Dave,
Porkyyorky isnt doing the filling rigs any more. What about this at gmac
http://www.eurocustomparts.com/Co2-Fill-Station
I would contact him to confirm what connections it has on. I'll keep an eye on the ukchineseairgunforum sales section for you as well mate.

There is all the info on that site with pics on how to make your own, failing that I can send photos of my filling rig.

The simplist set up, you use the valve on the extinguisher as the filling valve, all you need is a ball valve to release the pressure, a hose (mines a 4000psi grease gun hose from the bay(pennies)) and then a female fosters connection on the end (from gmac).

Thanks Greg, as usual, a picture paints a 1000 words….
That confirms just what I was thinking and I had just found all the components I need on the bay, but I think I can do away with the hose and make a direct coupler that will save a bit of co2…
Looking forward to getting hold of your nipples…..! (the rest of you can go work that out….)

The item you need is a Walther CPM-1 fill adaptor, not a paintball fill line the thread to the cartridge will be wrong,
These were available from Bill Welch @ Bills Walther Spares, but Bill has just past away and I don't know if the business is to carry on, try a email to Walther.
I have a CPM-1, and I could send you photos and a rough sketch of what you need.
Peter
Edit.
Just seen where you are based, If you could get to Hastings I could give you a fill .
Peter
Thanks Peter very nice offer, but I think I am sorted now. There was more wrong than just a missing fill adapter. I have had to make a new part where the can screws on to the pistol and while I was screw cutting that I made a fill adapter.
Also had to make a over valve, but that's another story, this was one mess of a gun, but should be good as new soon.
