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.

    Do not make inappropriate or offensive posts - including threats, harassment, swearing, prejudice, defamation, deliberate insults or name-calling, other negative remarks about this forum, its moderators and administrators or your fellow members. Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  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.

    Compressed air is nasty stuff indeed. Much more dangerous than the cute little balloons we blew up as kids. Compressed air doesn't want to be compressed, it wants to be FREEEEEEEE and will do whatever it can to escape, either slowly as a leak or all in one go and expanding rapidly. A 1 litre cylinder of air compressed to 300 bar wants to be 300 litres of air in an instant..........

    I saw this and it illustrates very well how compressed air can release immense energy in an instant, even at the relatively lowly pressure of tyres 2 bar (Car) to 8 bar (Lorry)

    That video demonstated immense incompetency and laziness! When I worked in tyre 4 at the Fort Dunlop making and testing HGV tyres they were always caged during inflation! I had many fail but never got injured.... That was incredibly stupid.... I'm lost for more words!!

    Totally agree. I know of a fatality around here when a truck tyre exploded and blew the fitter into the roof, killing him instantly.

    My uncle was killed in the same factory I was working at due to the incompetency of another person in similar circumstances to this video, he was cut into three pieces, something that will haunt me forever and why short cuts should never be taken, it had many knock on effects for our family... the least of all being I couldn't walk through the factory doors again and missed out on a great career working there. Stupid people incense me! :mad:

    w0w! That tyre launched his a$$! I saw on some website the results of some American teenager using oxygen in his PCP. Basically exploded as he took a shot. He apparently escaped without any serious injury somehow.:eek:

    Compresed oxygen is a lot more dangerous than ordinary compressed air particulalrly if there are any sparks/naked flames about.
    If you consider how much energy is required to hand pump a rifle cylinder of just a few cc and scale that up to a 12 litre bottle at 300 bar you can easily imagine the effect of all that energy being released instantly.

    Yes bad stuff. Any compressed air or gas is dangerous, metal cylinders filled to 300 bar or less are extremely dangerous. I once saw a nitrogen cylinder (about 6ft long) drop off a crane sling and land on its neck. The result? One unguided missile travelling at break neck speed through a packed hanger full of Jaguar fighter jets and engineers working. It missed everything and lodged itself into the side of an office brick wall. I have a very sincere respect for anything compressed to these levels. It is also a reminder that you must show a compressed gas sticker on your car/van etc when going shooting and you are carrying the bottle in your vehicle (it is law). If you are involved in an accident, the emergency services need to know you are carrying it. If not and it explodes whilst they are dealing with the accident, it most probably will kill someone.
