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.

    '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.

    So my leap of faith has begun, thanks to all of the first class advice from forum members I have started servicing my boyhood rifle!

    It came to pieces is seconds, very little preload on the old spring guess this is why!

    [​IMG]

    Next the piston came out and was given a thorough degrease. I also degreased the inside of the cylinder. I am planning to clean both up a bit before applying dry moly.

    [​IMG]

    The piston seal came off easily with a screwdriver and can be seen below next to the new one.

    [​IMG]

    The old breech seal also came out with a screwdriver and was well past it's best after 10 years of hard service!

    [​IMG]

    [​IMG]

    I fitted the new breech seal seen below.

    [​IMG]

    Tomorrow I will be cleaning up the cylinder and piston and applying dry moly to both. Will assemble the piston and apply moly grease to the spring before re-assembling the rifle. It's been fun so far!

    Here are the bits i am using.

    Advice please. Should I put Dry moly on inside of the cylinder? I am planning as stated above to apply dry moly to the inside of the cylinder and the outside and inside of the piston. I will then use good old moly grease on the spring. I'm not sure if applying dry moly to the inside of the cylinder might cause dieseling? Especially if it is applied to the last 1" or so of the cylinder near to the transfer port? Any advice would be greatly received :)

    Here is the polished piston ready to go back in when I decide how to lube the cylinder.

    New spring and original plastic spring guide re-greased with moly grease ready to go back into cylinder.

    [​IMG]

    [​IMG]

    I have applied my ambersil dry moly to the inside of the cylinder and piston and after it was dry I removed the excess from the piston before attaching the new piston seal. I then applied a thin layer of moly grease to the outside of the piston before putting it back into the cylinder. Was a tight fit but i was able to push it all the way down.

    Before re inserting the piston I gave the inside of the cylinder a quick wipe off with a cloth on the end of a bit of bamboo cane but will leave the grey coating on the inside of the cylinder as I believe that this is the now dry molybendum disulphide coating which will lubricate the inside of the cylinder and piston.

    Just need to compress the spring to get her back together again!
