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.

Best Hw45 Spring/piston Seal, Aftermarket Or Not?

    Hi, I'm considering getting a new spring for my HW45. Would you say that any of the aftermarket springs are better than the standard? If so which one?

    I took a couple coils off my spring and put a drop in kit in it. I've been unable to obtain any delrin spacers, so may just go with a new spring. My gun is putting out around 2.8-2.9 FPE on full power. Breech seal is fine, I'm pretty sure the piston seal is fine too. It shoots consistently but I want more velocity. I may also get an aftermarket piston seal, perhaps an Aussie one?

    Any input would be greatly appreciated. Before I strip the gun again, I would like to have the spring/spacers/piston seal ready to go.
    Cheers guys.

    Already have it in there mate, it shoots really nicely. I miss the recoil and power though. I was looking for spacers, but reckon I might just get a new spring, keep the kit in it for sure, then if necessary take coils off the spring when I can.

    Think I'll upgrade the piston seal to an Aussie one too, just curious as to which spring I should get..

    Springgoth,

    I have fitted the Custom Air Seals (Aussie) seal, and the TbT maxi-plus kit (http://www.airrifletuning.com/store/weihrauch-hw45-maxi-plus-kit/), and my 0.177" HW45 shoots beautifully now.

    ( I asked Mr. Stanning to clip two (2) coils from the spring, as I feel that the HW45 shoots more sweetly in the 4 to 5 ft.lb range)

    Have fun & a good Sunday :)

    Best regards

    Russ

    I al
    Hi mate, I had 2 coils off and kit in, don't have any custom seals though. I'm not sure on my next move, I've found a guy that can make me delrin spacers if I give him the dimensions. Or I could get a new spring, possibly a Titan XS one, which would surely need coils taking off (can't do at the minute, my old man is an engineer, he did it for me at his workplace)and them whip the TBT kit back in. Get an Aussie piston seal, but it'd take a while to come. Or simply give it a service and replace breech seal. Though I miss the heavy recoil on it, I loved the feeling of it flipping up in my hand after shooting it. Tough chooses made tougher by being a bit skint at the minute. Lol.

    You too bud, or Monday at least ;)

    I am using this one. However I think getting a stock spring with a tbt kit would be easier than buying a spring from US. Same reason I didn't use a tbt kit was because ordering from UK is not as convenient as from US to me. I like the delrin spring guide and the tbt kit, but ARH doesn't provide that... Why buying an aftermarket spring is another story but not related to performance or mods...

    I am using the Aussie main seal too.

    And I think the seal and the spring are not taking a very important part in taming the beast. The non metal tbt spring guide is, and a good polishing and lubing on the spring and the piston is.

    HI, we can get the Titan XS springs over here. I think I'll try a couple spacers first though. Will definitely give the whole thing a service.

    Which springs do you have there?

    I have a hw45 silver star .22

    I took mine to bits, cut a couple of coils off the spring, degreased everything, then polished everything, fitted Oz red seal, a very small amount of grease applied via a rag, it was more a light wipe down. Rebuilt it and even with shorter spring it was a wrestle but got it all back up and running.

    No dieseling or smoke and wow what a difference, ran it over the chrono and it was 5.3 ft/lbs. I have been watching the power and it's settled at 5.6 ft/lbs ish but can always strip it again and take another coil off.

    I did the same as you but mine puts out less than 3FPE full power. Crazy how these things work. If I can find the dimensions I'm going to get a couple delrin spacers ordered, then give the pistol a service and see where we're at.
