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.

Scope Lens Keys....

    Good evening Gents... I recently acquired a Walther scope with a rifle I got... NOT the best quality but it will do for now..

    However, I think a previous owner must have adjusted the objective and super-glued it at about 68.35 yards...!!!!

    Anyway, I needed to move the objective lens to a more.. acceptable setting BUT.. there was glue in the thread and I didn't have a special tool to loosen off the locking ring.

    This is where my favourite saying comes in.............

    "Necessity is the Mother of Invention"

    So, measuring the internal recess of the objective tube (over the threads) and gauging the cut outs on the locking ring, I fashioned a small key out of a piece of 1/8" stainless steel plate I had lying around, that fit inside the thread diameter and into the 2 slots on the aluminium locking ring.
    I also filed a concave middle section so that there was plenty of clearance over the glass lens.

    After a little cellulose thinners on the glue and careful scraping away of the hardened mess with a needle and scalpel point... I was able to start to "break the glue seal" of the locking ring.

    By placing the key vertically in the end of my vice, I was able to slip the objective end of the scope onto the key, locate the slots on the filed pegs and loosen and adjust the locking ring...
    By doing it like this.. I could keep a steady axial load on the locating pins and turn the scope by hand to "feel" for any movement.

    Now the objective is set at 15 yards at 9x magnification (purely for plinking in the garden), and I have the key available if ever I decide to adjust it further.

    Just thought I would share my design with you....

    Quick, easy, simple.. and... CHEAP!!!!

    Thanks for sharing. What I like most is holding tool in vice, leaving hands free to manipulate scope.:thumb:
    Sections of a hand saw blade should also have right temper to make good key.

    Nice work. Looks similar to the Hawke ones.

    Like the idea of holding the key in a vive too. I always find them tricky when holding the scope and trying to turn the key.

    Well done.
    Exactly what I would expect from a thinker.

    The 'bit of stainless plate I had lying around' sounds like my reasons to my wife why I don't throw anything away.
    It may be rubbish today but it could be invaluable tomorrow!

    I have made a few things like that for locking rings. most can be loosened with a cut down credit card or similar if your lucky.

    Looks good. I have need for one to use on my Vortex Copperhead which must've been set by the same guy did yours. ;)

    I have used the internal jaws on an old set of vernier gauges and that has got stubborn one's loosened before it may be worth a try - dont forget to use something like a bit of card to protect the lense if you slip .
