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.'

  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 see the cylinder already has a breather hole for the standard regulator..
    So looks like a remove, replace, adjust (maybe not that's simple in practice!)….

    With my wildcat mk2 I think it took me about 20 mins start to finish to swap out the standard reg to the Huma reg.

    Pressure test and first fail...
    Leak from back of the gauge.
    Added o ring refitted, cramped tight (gauge now side on marking) and no leaks...140 bar fill and wait to tomorrow to check for any more leaks.

    The regulator was marked as set at 120 bar, and would you believe it....
    IMG_20190907_162813.jpg
    Gauge reading 120 bar.
    Well done Lane and the gauge from hw tuning must be accurate! :up:
    Checked it a cocks and fires fine...
    Test shoot, chrono and adjust next week...

    It was no surprise it has been messed with as the when I got it it was running at 10ftlbs, the brass spring adjuster was mangled, as was the adjuster (the allen thread was stripped). I got it out with a extractor and then found spring had a spacer added presumably to increase hammer spring pressure. All sorts of messing. Replaced bits and returned it to normal and been fine/consistent since until the pressure loss.
    Through out all of this, it has been super accurate, and since I self modded the shroud, virtually silent too.
    Only had time to put a couple of shots through the chrono and getting 8ftlbs, so likely some backing off of the pressure and spring adjusting to do....
    Most of the info to do all this I have got from this forum and some YouTube clips which is why am adding this to maybe help somebody else in the future... Thanks guys

    Was not as bad as I thought, cutting the laminate. It was a bit battered anyway, but still a worry, packed wood in the cavity so as not the damage the inside when drilling through. 25mm bit and gently does it. Quite pleased with myself after.

    Is HW tuning some kind of unit of pressure?

    Was thinking you have it from BAR (shop)

    It is simply make/supplier of the pressure gauge I fitted in place of the standard air bleed screw....

    Put simply. The gauge in this location will give you the pressure behind the the regulator (the pressure your regulator is running at). The gauge at the fill port end gives you the pressure within the main cylinder in front of the regulator.....

    Yes dead handy for identifying regulator issues, whatever type you have. Should be a std fitment!

    Update.
    Ran the rifle through the Chronograph with the reg at 120bar. No matter what spring adjustment, got no more than 9.3ftlbs?
    Emailed Mr Lane for a bit of advice, got super quick reply and asked to persevere with the pressure setting but maybe reduce it slightly by 10 bar and see.
    Was about the strip it down and adjust the reg as advised, but then remembered I'd ordered a replacement standards hammer spring from Chambers that I wanted to fit. When I took out the spring from the gun, although it was the same diameter it was about 2 coils longer. Anyway I replaced the spring and wound the adjuster in a couple of turns, and out of interest thought I would quickly chrono before bleeding out the air.
    Well was I surprised or what. The chrono produced a highly illegal figure! :eek:
    Quickly took some tension off and now at 11.5ftlbs.
    Will test again in a couple of day when I get a chance with a full air fill when the regulator has settled.
    So basically it was the hammer spring at fault.....

    Well the wildcat can run with 120bar as Lane had set it....
    There you go... :thumb:

    It's a 22 and a mk1 (not that I think there is a great deal of difference internally) . Happy tweaking...

    Out of interest, why 120 bar? Air Fective set mine to 90 bar and its spot on (they recommend 90 bar as the optimum) Unless yours is FAC?
