Default Steyr Hybrid hammer

I feel some tinker time coming on with the hammer in my Steyr.
I'm convinced that the new style hammer is causing inconsistency due to the fact it is able to rotate through 360 degrees .
I have an old style hammer with the long flat spot along its length and intend to make a few modifications to it and replace my new style hammer.
Is there any thing to be gained with the light hammer verses the old heavy hammer?
I'm thinking of adding a cup for the spring at the back and a Ptfe guide at the striker end.
I feel the striker end is where the consistency issues are with it rotating and finding high and low spots in the action.
Any advice on hammer set up would be greatly appreciated.
Simon

Default Can't Waite lol

Estwing is not an option for the Steyr, Darron.

I done loads of work on this and made a few hammer variants but a well set up standard external power hammer was still the winner. Youd be better off looking at the issue youve got and finding out why. It wont be because steyr have designed it badly itll be something thats at the end of its life. A serviced steyr will give an 8fps spread with all standard guts. Do you need better than that? However if youre like me and like to tinker then ill be watching the "steyr hybrid" thread with anticipation, hoping you found the elixir.

Si I have noticed that when screwing in the external velocity adjuster you can feel and hear the hammer spring binding. This is reduced by polishing the ends up, it is also improved by adding small mushrooms to each end. The spring needs shortening first, also played slightly with one at the back only.

I have managed 3ftp variation with weighed pellets after this.

I experienced low shots hitting the string level. This has since stopped since replacing the reg which I discovered was pushing out 120 bar.

Default Marks

Brian I have a polished spring with a stainless ball in the front going into the cup on the back of the hammer.
As I have said the new style is able to rotate, I proved this with a marker pen and several cocking cycles.
I think the very front of my hammer is slightly of centre . So when it rotates around it occasionally drags on the inside of the action.
My logic is this could have a couple of effects, slowing the impact on the valve or slowing the valve closing .
I'm thinking the second effect may help to cause my high shots that I have been witnessing .
I think the first approach will be to reduce the end diameter then put a floating guide around it.
I'm also thinking Spring guides for the backend, but may do in stages to see if each has an effect.
I forgot to point out that on stripping it has highlighted a marked area on the end of the hammer.

Thank you for your input but I think youre full of sh1t. Lol
I do appreciate your input Richard , but telling me that Steyr have not designed it wrong is nothing new.
The hammer was new to me from Harry when I had a replacement trigger block.
The standard hammer gave big issues which a buddy of mine helped diagnose , I then had a replacement hammer that was intended for an FAC rifle.
The only difference was the length of the cup and a solid block at the front.
It worked a lot better but shows wear marks when periodicly removed.
I think the original hammer with the flat spot is more consistent because it can not rotate , so the hybrid part is to remove the post off the back and install a cup.

got any pics of the wear marks simon ?

do they come back to the same place on the hammer time after time .....ie consistent high spot ?

can you clock the hammer to check for straight and roundness ?

how's the bore in the action ?.....straight ? ......round ? .....any high spots ?

does the steyr hammer strike the valve from it's centre , or offset ? ....i cant remember

lots of pics please .....i love all this .

Will mark spot and check .

I will check that also , the question is how far back to check it?

how's the bore in the action ?.....straight ? ......round ? .....any high spots ?
It's hard to see into where the issue is . It's in the depths of the trigger block.
Straight through round bore for the hammer to follow.

does the steyr hammer strike the valve from it's centre , or offset ? ....i cant remember

Hammer strike is central to the valve and through bore.

lots of pics please .....i love all this .
On your Walther hammer mods did the lighter hammer improve things or did the extra Spring pressure off set the gains?
Thanks Simon
