1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    It's an old BA set cylinder, fill pressure apparently 200 bar so might be a bit low for most PCP's.

    The Blk/White markings on top are the (worldwide)standard markings for Oxygen,usually administered to aid the internal tissues/blood etc after a trauma, this looks like its been used, and i stress for H&S reasons, by the way IS only an educated guess,,Possibly, an ahstma sufferer,who needs occasional home treatment,and with a reg.fitted to the pillar valve,could help their system by breathing through a simple 2 nd stage Diving reg.

    READ The Labels !because they will tell you much about its past reasons for use .2.again.
    Could be a Diving Cylinder which ,when a scuba diver, has had an "incident" would use as ,a.a precaution to minimise any trauma internally.
    Possibly stayed too long at depth,causing an overload of the Nitrogen saturating the body tissues,while breathing Air at depth, thats 1 precursor to getting "Bent."for now ,thats reason enough,in a diving sense.

    Any Breathing Gas mixture above 21 percent O2 a label on the cylinder would give a percentage + of the mixture,upto 100 percent,as any increase oxygen can benefit a divers physiology Under pressure.a very obvious labelliing would be present in a dive situation,and the word NITROX,would be clear to see.

    Remember matey, that the labels will tell you most probably, what it was being used for.
    The B&w is for 100 percent oxygen use (medical) and or an obvious sign,for divers for more than the reason i gave ya.

    Ask the Farmer, Read the Labels. Photos on here and someone will tell you, probably with less to teach on the pros and cons of nitrox (Enriched Air Nitrox) in Scuba.

    This cylinder i would first off open so a slow whisper of a hiss comes out and smell the air, if it smells, fuel like or off you could not use it for much at all apart from blasting dust away, but be carefull!

    Go slow,the needle will tell the fill pressure if any.
    A true Oxygen clean cylinder and the valve on top would have been dedicated for the purpose with both having At Last Test been oxygen cleaned to Higher levels than normal Air Cylinder for scuba.

    I hope this long winded reply hasnt knocked you sideways !!! LoL???
    I dont have any pre charged guns, but the cylinder if still within test dates will I think be usable for those guns.
    Take it to a dive centre and for safety sake, they could tell you whats in it, if anything, test date will tell you if it needs serviced,which entails emptying the bottle removing the pillar valve and guage to visually inspect internal surface for any comdensation which of course would after many times being run to 0 on the guage help some rust to start but this would be more likely had it been poorly filtered over a long time at source.

    But 02 servicing wouldnt be necessary for guns.

    Sorry to go on but thats the way of the ScubaInstructor needing his bed, good luck with the cylinder, ATB Dennis.sorry all who think im wrong add or subtract at your leasure Mods.

    The black & white quadrants show it's for breathing air, not Oxygen.

    Hi Andy , assuming it is for compressed air all I would be carefull of is that the gauge looks stuck (it is not on zero) so may give you a false reading when filling and if the fill valve is the same as mine open it very very carefully as some of them with fill to full pressure at a scary speed. You don't want to risk blowing you and your gun up ! ;) Imagine letting 300 bar go into a 200 bar rifle ! ouch !
    hth , rich .

    On tye label ir reads fire protection devision and oteac ltd, oteac is integrated saftey firm based up in Aberdeen who specialise in saftey on oil rigs, as it also says fire protection division chances are its a air tank for a fire fighter on board a rig so it would only hold air or oxygen. Read the labels as this will tell you about it, h&s laws are handy for this stuff... hope it helps :)

    If you get it safety tested, filled with air from a dive shop, and swap the gauge then yes it is.

    Erm copied from Wikipedia!

    [h=4]Gas mixtures, mostly for diving
    [/h]Diving cylinders are left unpainted (for aluminium), or painted to prevent corrosion (for steel), often in bright colors, most often yellow, to increase visibility. This should not be confused with industrial gases, where a yellow shoulder means chlorine.

    • Air diving cylinders have a white and black quartered shoulder or a white top and black band.
    • Nitrox cylinders, a diving mixture of nitrogen and oxygen, have a white and black quartered shoulder or white top and black band. Can also be coded with green stripe on yellow bottom.
    • Heliox cylinders, a diving mixture of helium and oxygen, have a white and brown quartered shoulder.
    • Trimix cylinders, a diving mixture of helium, nitrogen and oxygen, have a white, black and brown segmented shoulder.

    Linky here!

    http://en.wikipedia.org/wiki/Bottled_gas

    So it is a 206 bar cylinder from a BA set as the OP stated. Filling the Logun to 180 bar means you will get a few fills out of it, not as many as a 300 bar, but still capable of topping your gun up!

    AFAIK, the crack is thus:

    The bottle looks very much like an ex-fire service B/A cylinder. I think a glut of these came onto the market around 15-20yrs ago; perhaps because the service were selling them off to upgrade to higher pressure offering / replace with newer offerings.

    Some things you might want to consider:

    The bottle is most likely 207bar; if filling your rifle to a guesstimated 180bar you won't get many fills before the pressure in the cylinder has fallen below that required to fill the gun and it's effectively empty.

    Before the bottle can be legally filled it will need testing (round here that's around £45 but if you live in a less extortionate part of the world it should be less).

    Despite the fact that the cylinder was probably designed for use out of water, the lack of integrated gauge and bleed may mean that it only gets a 2.5yr test cert as opposed to the 5yr cert given to "surface use" bottles.

    The gauge assy looks a bit shafted - you'll need a new gauge (around £20) and hose (around £15).


    So the bottom line is that it will cost you the price of a gauge, hose and test to get it in working order, and even then you'll only get a few fill before it needs topping up again. Unfortunately due to their low pressure and possible frequent test intervals these cylinders are basically worthless (I had one the same with no gauge assy and I literally struggled to give it away).

    If you don't mind the low fill capacity and can get it working on the cheap (cheap test, used hose and gauge) it will do the job if you're on a budget. However, if you can chuck a few more quid into the pot around £100 will get you a used, in-test 3L 300bar cylinder which will give you far more fills and will have less frequent test intervals ;)

    Thank you so much guys for making it easier to understand ,I think I'll just leave this one alone and buy the reccomended set up. Was hoping for better news with it being free but don't want to mess about with it thanks again guys and all the best

    Seems I remembered correctly then !
    though some of the guys back then were getting into the very bright colours !! Most of us just had the black and white quarters ... The colours were a bit trendy lol

    happy days
