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.

  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.

    P1000520 Chrony Armour note the cable hit.jpg I had not had my F1 very long before I decided to use some protection for the sensors.
    I cut two blocks of Makrolon then added heavy duty Velco and fixed them to the sensors
    where they face the shooter. Job done. I checked all my pistols, all good.
    Today I set up as before, but then nipped my finger in the cocking lever of my HW45,
    it just fell under its own weight! Huge Vee shaped blood blister, straight under the cold
    water while I drank a cup of tea, shrank back to virtually nothing after 5 minutes.
    Out to the Chrony, first shot hit the cable where it crosses the middle joint, bare
    wire exposed and bent sharply in half but does not appear to be broken so I will either
    just tape it up (favourite) or fit a mini plug.
    The one place I did not think to armour! It would be expensive to make a Makrolon cover
    and a nuisance to carry so I will think this one through, something like a clothes-peg clip but it needs to cover the extended cable and the cable has very little slack .....

    My Skan is armour plated - just in case. :D

    I've not missed the hole yet, but I know I will one day. :rolleyes:

    You doing your chrony testing at muzzle output or down range energy?
    If it muzzle just aim higher, you'll be surprised how much higher than the sensors you can fire to get true readings on the F1.

    I put mine on a camera tripod in front of a bench but set lower down. With the rifles on the bench rest keeps it all in alignment and I can cycle a whole fill of shots easily.

    My guess is Sky is prepared to do some downrange energy calculations to go for full Armour plating

    Why thank you Carl - how did you manage to find that pic of me. ;)

    That's how it came - I'll spray it the next time I get in the shed. I have some silver in there somewhere.

    I have had a chrony before and not hit it, although it had been hit by "the borrowers"
    Anyway I looked at the instructions and it suggests that the joint in the wire rods,
    should be used as a sighting level (roughly 140 mm 5 1/2" to centre of joint)
    Seeing the Skan in full armour, I wonder if something similar with a target aperture
    could cover the cable and encourage the correct test shot height? Hmm .....

    I'm guessing you aimed lower right? Else that's some serious issue with the sighting on that gun to hit that cable.:eek:

    I was watching the readings, cocking, loading, shooting, and just ended up with my pistol too low.
    Some people hit the easy bits I went for the brown wire ;)

    @zip ting good idea. I'm going to buy some polycarbonate and do the same. Looks like you have used about 6mm thickness?

    I used what I had and I think it is 10mm, if you look on the bottom left of the front block it has
    been chain drilled to clear the on/off switch but only about half way to still provide protection.
    Also my heavy duty Velcro fastening tries to pull the front printed foil decal off when the
    weather is warm.
    The rear block has a shallow cut out to clear the ribbon cable. The blocks are removed and
    stored inside the Chrony as it won't close with them in position.
    The sunshade support wires drive me mad, being loose in the connector, so I tightened them
    up by giving them a light squeeze with a crimp plier

    *These guards can be purchased from e-bay, I have no connection to their venture.*
