    ahh OK, now I see, sorry... so if the hammer (cage) is quite heavy, it's going to be taking a lot of spring energy, which isn't purposeful in terms of providing energy to hitting the valve (which is only opened by the slighshot piece). What is the weight of the cage and also the weight of the slingshot part ? That'll probably answer the question...

    PS some other minor design improvements to consider... (but no point until the cage mass issue is sorted)
    - ensure the spring that holds the slingshot back is as light as possible
    - the central bolt that passes through the small hole inside the hammer/cage/body should be smooth at that section

    PPS A Ti cage might work, ali will wear

    I would suggest that the actual hammer part is not heavy enough to retain enough inertia to open the valve or that the spring is not strong enough to provide enought energy, when i make SSGs i ofter need to increase the hammer spring strength to provide the extra innertia to still open the valve after the preload is removed.

    yup.

    I was actually going to suggest SSG route might be easier too...

    Having had good look on how I can improve things, an SSG would be the easier route.
    I hope to make one internal to the hammer,
    fixed at the rear.

    Needs a bit of thought first.
    Thank you for your help.

    I've done a few SSGs, i stuck up a post on here a while ago. The telescopic spring guide version is anways an option, except for extremely short hammer strokes, and fits inside. I don't think external devices are a realistic option due to UK power laws, unless on bullpups where external to the action is still internal to the stock (whcih I did on my Kral and JKHan)

    I have an external SSG adjustment on my R10 (only way to do it), don't think it's a problem as it not a problem having anti tamper removed from air guns,
    Looking atg that hammer you could do something similar to my Kral hammer if you have a lathe.
