Much better, can even be called perfect.
And should be standard on a 2100 pound costing rifle IMHO.
Yep, that should do it too.
Here’s the weak point especially on the ambi
Works just fine mate .
Heres the bit you couldn't see in the first pic with the o ring fitted .
The o ring squidges ( real word ) into the first thread or 2 of the action and sort of seals a bit but also kinda creates some resistance sort of like a nyloc nut but in reverse to help with the tp unscrewing itself situation .
Im not tightening tp ' s very tight at all theses days , just enough to see the air cyl start to move and then that's it
it does catch in the gap between action and chassis when you remove it and some times gets semi dragged out of the groove .
Its the same size o ring as breech seal and eventually will get chewed by constant refit and removal .........so will need a new one sooner or later . I reckon most peoples guns dont come apart as much as mine though .
looks nearly black too dunnit ?
Here's a thing .
At the moment ,I do like to see a seal at the tp so I'm shimming until no leak .
On my gun i get some rubbing at the top of the stabiliser where it enters the chassis .
Ive seen guns that dont do this and don't leak either
Oh yeah ive started mucking a bout with smaller than 4mm holes too ................I'm like that
Oh double yeah , I'm currently quite liking 87-88 bar on the reg too
Talk me out of it if you can
I appear to have taken your thread off course ...........
I had my TP quite loose, just nipped up, but was getting some leakage. Had a good seal between TP O ring and bottom of bolt, so I guess it was getting up past the threads?
So, I've tightened the TP up more than I was doing and all is now sealed.
Careful you don’t bend the chassis phil
I expect some clever sausage will formulate a torque setting for the tp at some point
What kind of ham fisted f***** do you....
Ah, yeah, good point well made.
That's really good Phil pity steyr didn't make the ports so an o ring fits like that. I guess it makes it easier to adjust the height of the port too rather than mess about with shims
It will probably be way too low for most people's torque drivers, even if they can get anywhere near it. I doubt you're even hitting an single Nm on them the way you're doing them now. Remind me when I pop over and i'll bring the Gucci torque driver over.
Still shimming for the port height .
So that the chassis stops the port and action from being pushed downwards by the stabiliser
I’ll try do some pics and a write up or even a little vid when rob comes round
It’s simple but hard to explain
You’d be surprised how easy the chassis flexes Phil
This was the point of the thread
and prob why the factory tell you not to go mental tight on the tp
I meant not having to shim the TP not the chassis. The compliance on the o ring will mean you'll have some adjustment for height and help keep tension on it so it doesn't come undone.
I recently rebuilt mine after getting another new housing off steyr, I checked to see if it rocked when loosely assembled without the cap screws, TP and cocking lever fitted, everything was perfect. As soon as I fitted the cocking handle without the cap screws and TP fitted, it suddenly started rocking. What causes it is the combined height of the handle and o ring it sits on. If you put a straight edge across the housing you can see how much the cocking handle is sitting above the housing.
The o ring steyr use to shim the cocking lever is a very hard one. I have in the past experimented with removing a few thou off it but then you get quite a lot of scuffing on the opposite side of the housing and underneath the cocking handle too. I'm currently experimenting with an o ring with a softer shore rating. So far it hasn't caused any scuffing or gouging on the alloy chassis and feels more smoother and positive feel when cocking too. When you tighten everything up the softer o ring allows the housing to bed and sit better without fighting the harder o ring. The chassis still needs shimming on the reg backplate but not half as much as when using the harder o ring.
Yes mate still shimming the tp
For easy repeatability when fitting it
In a pathetically transparent attempt to keep this thread alive before i announce that I’ve made a batch of TPS for sale
I made a little vid of the effect of tightening / over tightening the transfer port
as soon as @RobF helps me post it
