cant tell from the pics.. dos the smaller metal cylinder get accelerated by the hammer spring, then arrested allowing the outer hammer to continue? im trying to work out if you are loosing too much hammer spring energy moving mass...

The outside is a cage which holds the slingshot. The valve protrudes by a millimetre so the slingshot needs to sit inside the cage.
The spring holds the slingshot to the rear of the cage during cocking and sits inside the hammer spring guide (the white bit).
It's the closest I could make to the original hammer

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.
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.
