Walther CP1

[nige346]

Have you tried protek supplies in Bognor Regis, I got some bits for a CP2 inc the now nr impossible to find dry fire switch, I also recently picked up a piston for an LG55 which really is rocking horse xxxx,

Worth a try, he may what your looking for

I had to make a service tool for my CP2 cylinders although it doesn't quite fit the CP5 cylinder I tried it with. Its only a little filing required though.

I used a 14 mm across flats bolt in the valve, with nuts double locked on the thread, and a big socket wrench, they did turn, and it would have been better with the nuts welded.

My other problem was the hex on the end of the cylinder had been butchered so I had to clamp that in a vice.

But I did get it out with a touch of warmth.

It is a lot easier to just unscrew the valve assembly. I turned down a hex rod until it fitted inside the 'o'ring I then milled the top away to leave a short screwdriver blade that had parallel sides and just fitted in the slot. Finally i milled away the middle of the blade to provide clearance for the valve pin. I put it into a vice blade up and gentally tap the cylinder over it. it is then not too difficult to unscrew the valve and clean the sealing surfaces.

We only want to remove the valve assembly and fit new seals to the valves.

The first three have already been done and are holding gas - no problem - but we have one valve that will not shift at all so we may have to make something like you have done so we can give it a little more heavy duty persuasion

Thanks for the link - that looks like a good substantial bit of kit.

I will take a look around the workshop to see if I can find some suitable steel hex bar and knock something up along similar lines.

Did you "temper" the two "lugs" that are used to locate and twist the valve - or was the steel strong enough to be left raw after machining?

Hi Robin,

We already have a device knocked up like that but we just want to unscrew and remove the valve - not remove the end cap from the cylinder.

The three cylinders that have had their valves removed and re-sealed are holding gas and working well - it is only this last one that is proving to be a bit reluctant to take a look at the outside world!
