  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.

Any Information On The Daystate Tsar Type 2 Trigger Adjustment?

    I'm a new owner of a secondhand Tsar (also my first high end target rifle) and I'm amazed at how light the trigger is and also surprised at the narrow transition between the first and second stage. I've downloaded the single page of info on the type 2 trigger from Daystate but the instructions with it are absolutely minimal. I've made some adjustment to increase the first stage travel but it's still very light after adjusting the weight. Does anyone know of any source of information on setting up these type 2 triggers? I could just keep playing with all the adjustment screws but I'm a little worried about over adjusting the trigger weight (I've gone close to 2 turns clockwise so far). It would be nice if there was information somewhere that gives the range in number of turns for each of the 5 adjustments and perhaps some guidance on the best sequence of adjustment. Any help would be much appreciated.

    Many thanks for the link - from the same website I was able to download the
    ATAMAN M2 Sport Field Target schematic which is basically the same as the Tsar but unfortunately the trigger is different to the Daystate type 2 trigger. The Ataman schematic will be very useful so thanks for that anyway.

    Thanks jesim1 but unfortunately that is for the type 1 trigger.
    Here is the only information I can find for the type 2 trigger but using this as a guide I'm having difficulty working out how to adjust the 2nd stage weight. If I take the schematic literally it looks like there is only one trigger weight adjuster for the 1st and 2nd stage:

    Hi Lev

    I see what you mean - if you expand the diagram it does look like there is only one weight adjustment, but that should be fine as long as you balance the first and second stage adjustment screws looking at the way they work on the sear.

    I would adjust both so they are out as much as possible, then I'd set the first stage so I could feel it before setting the second stage to let the shot off (then balance the two). It's this second part you want to get the weight right with, as the first stage is just to let you know your about to let it off with just a bit more movement as the second stage engages. So definitely A for weight, and B&C by feel.

    Thanks Jesim1, that's not too far from my approach at my first attempt but I like your idea of backing off B & C first and then start adjustable B & C back in so that I can feel a little bit of 2nd stage weight - I'll try that next. I was a little concerned about further clockwise adjustment of A because I was starting to feel resistance to further turning. I think I might be missunderstanding the effect of B & C, maybe they also balance the weight applied by A between the 1st and 2nd stage.

    Due to the leverage effect "A" should feel lighter, and as "B" makes contact it should take over the movement of the sear giving way to the actual shot. So again, it's likely to be trial and error depending how you like your trigger, but it's hard to do them together initially, which is why I suggested backing them off so your only dealing with the first stage and then can "feel" where the second stage comes in and know your now dealing with that.

    Or I could be talking Betty Swallocks :D

    Thanks for your help with this. Looking at the the schematic again and understanding what's going on from what you have pointed out, I'm wondering about trying the following method of adjustment:
    1 Leave A where it is for now where I'm just feeling resistance from previously turning clockwise.
    2 Back off B and C.
    3 Turn C clockwise in small steps while cocking and seeing if the gun will fire between each turn.
    4 When the gun fires back C off (say 1 turn - trial and error may be needed)
    5 Turn B clockwise in small steps until extra weight can be felt when firing due to B just making contact with the lever before C would have caused the fire.
    What are your thoughts on the above please?
    I'm also wondering about the effect of increasing the trigger angle by backing off E. I'm thinking this might a give a slight increase in separation between the 1st and 2nd stage (not sure about that as it won't affect the weight difference between the 1st and 2nd stage).

    It all makes sense to me, remember we are only talking trigger adjustment, just have a go, you have nothing to lose and won't damage anything. If one way does not work, back everything off and try another way till you get the right result :thumb:

    A simple way to adjust a 2 stage trigger is to back both first and second stage out so the trigegr does not fire.
    Turn the first stage in by small increments until the rifle fires with the first stage. Then back that first stage screw out an 1/8 of a turn.
    Then screw the second stage screw in bit by bit until you get a second stage feel and it fires safely on the second stage.

    If the first stage is too short, you can back out and increase the second stage to get the trigger to your liking.

    Only when the first and second stage are set properly would I adjust weight.

    Robs, thanks very much for this, together with the help from others who have replied I think I now have a good understanding of how to make the adjustments.
