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.

    I have ended up with this,HW77K in .177

    [​IMG]

    Had some fiddling to do though :(
    As it was it was a death trap,the trigger had been fiddled with to the point where it didn't exist as a trigger,you could cock it and breathe too hard on the trigger and it would go off.
    I adjusted it a bit but then it wouldn't release,equally as dangerous having a loaded gun I couldn't discharge.
    Anyway after a bit of a search online and removing the trigger unit itself it is now safe and works as it should.
    I have also removed the bear trap mechanism as well as it did my head in not being able to de-cock the rifle whilst I was trying to adjust the trigger initially.
    It is a slightly older model,about 1989 apparently according to the serial number,I had one in 1986 and that didn't have a bear trap on it then so they must have bought that in within those 3 years.
    It also looks like it has been apart at some point as there looks like moly grease on it rather than the usual gloop and the fact that the trigger pins and underlever pin came out relatively easily.
    Goes off with a bit of a bang but it isn't dieselling and the power averages out at about 11.6 with AAs so okay there.
    Will fiddle with it a bit myself at some point,partly why I bought it to be honest,to have a play with something.
    Stock has been slightly refinished with something as it is quite dark and the white line spacer on the butt pad is tinged a reddish brown.

    An ideal candidate for a Tinbum drop in tuning kit. You know it makes sense. :coffee:

    More than likely,it is in bits already,when I shot it a bit more I noticed there was quite a pronounced reverberation going through the rifle.
    I have noticed that the spring looks original to me,there are no pre-load washers on the back and nothing in the piston itself.
    Spend the last hour or so cleaning a polishing the piston,luckily it just fits into my drill so have been using that and some fine wet and dry to get it nice and smooth and shiny :)
    Few marks on it still but they must be quite deep and you cant feel them anyway

    Been a bit of a productive day.
    Finished polishing the piston and compression chamber so they are both very slick and shiny and lost a coil off the spring,there is very little preload on the spring now so that might drop the power down a bit and get rid of some of the twang and reverberation.
    Also stripped the stock back to get rid of the nasty varnish and whatever else had been put on it.

    New piston and breech seals have just turned up along with some grease so have started to reassemble this as much as I can.
    Still waiting for a Tinbum kit to arrive so cant complete it till tomorrow,hopefully.
    The piston is really smooth in the compression tube with some grease on it,it sounded rough as hell with no lubrication on it and wondered if some simple grease would cure it and it did :)

    Interesting afternoon,after getting my skin caught up in the end block and cutting myself I had a walk for a few hours before coming back to this.
    Reassembled it and it is nice and smooth to cock but it went off with quite a bang but it doesn't diesel.
    Stuck it on the choro and had a nasty surprise though!
    Suffice to say some work was needed so I opened it up again and cut the same amount of the spring that I had already removed and now it has dropped down to just over 7ft/lbs.
    Very low now but that is without any preload washers or top hat in the piston so hopefully it will go back up a bit from where it is now.
    The power has crept up slightly over the 20 or so shots I have put over the chrono.
    Fires nicely as it is with no twang or reverberation that I was getting before.
    I was surprised how much an effect polishing the internals and re-greasing it had on the power though considering when I got it it was on 11.6ft/lbs with the spring at it's full uncut length.

    Found out something interesting today.
    I sent an email to the shop where I got this from commenting about the state of the trigger.
    The reply came back today and said that the rifle was tested and found to be low on power when it was brought in at around 8ft/lbs so it had been sent to be fixed and was checked on being returned and found to be 11.5ft/lbs
    It has been suggested that the trigger hadn't been touched but somewhere along the way someone had had a play with it.
    Anyway it explains why the spring was in such good condition for it's age.
