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.

    To close this box once you've read it (and the Rules), click on the X in the top right-hand corner.

  2. A reminder of one of the Forum Rules:

    'Behaviour

    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.'

    There have been changes made to our censoring software in an attempt to help with this growing problem.

  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.

    Gentlemen... being a new proud owner of a rifle that has a nicked pellet probe O ring... and the need to replace it... without EVER having stripped this particular rifle down!!!!!

    I thought .. " I know... Youtube it..." and so I did... and the range of videos from a well known and respected tuning company gave some great tips and advice on how to change your pellet probe without stripping your actions...

    However....................

    Some of the methods made me think... "Hmmm that could damage the O ring spreading it so far..."... so.. what is the alternative...... Make a tool!!!!!!

    So in the best traditions of making summat useful from some rubbish and odds and ends you have lying around... I have come up with simple nut effective solution...

    CAVEAT. This model is specific to the BSA range of SE rifles....

    From an old broken toilet door sliding bolt.. and a bit of old microbore copper pipe..... and in GLORIOUS FULL COLOUR.... I give you... Hals ACME pellet Probe O Ring Putter Onner....

    We start with the odd bits and bobs....
    20200517_162234.jpg

    A quick tinker in the lathe to get some diameters for the probe hole and O ring diameter...
    20200517_164311.jpg

    Cut up the brass and copper into narrow strips...
    20200517_165206.jpg

    Having decided that the brass was better, plop the locating plug onto the end of the brass strip with a boatload of solder flux....
    20200517_165421.jpg

    And solder......

    20200517_165554.jpg

    Then clean up and polish all the surfaces...
    20200517_170539.jpg
    20200517_170548.jpg 20200517_170559.jpg

    Take the necessary O ring and slip it on the O ring diameter
    20200517_171816.jpg

    Remove the old O ring via a needle hook or other such implement and retract the bolt fully
    20200517_171837.jpg

    Now simply locate the probe hole pin into the probe and GENTLY slide the bolt forwards to the breech.... the probe can be lightly held in place whilst the new O ring is simply rolled onto the pellet probe diameter and into the O ring recess....
    20200517_171855.jpg


    Then, simply ease the bolt back and remove the ACME tool.....

    I hope that you have found this usefull....

    Stay Safe Gentlemen....

    Very good improvisation, but you used far too much flux ( and it looks like the acid based , self cleaning type) . Did you clean residue with boiling water before polishing?

    Either way, it's a cracking idea, well carried out.

    Heyup Radlad... Yes mate.. I keyed the brass, fluxed it soldered it, then when cool, swilled it in cellulose thinners before a quick polish, then wiped down with thinners again....

    It seems to work...:thumb:
