    Not long before this rascal was gonna let go .

    It came out of robs winter league reg that was working ok .

    Looks like had been trying to escape past the piston

    Soft 70 nitrile .

    New one did exactly the same within a few cycles , so it's got a harder material O ring in there now .

    Naturally different o ring had different fit So adjustments needed to be made

    It's great work Phil but i do wonder what difference you'd see to down range grouping for a shot taken at say 84bar and then the next at 88bar?

    That's next on the list. But having seen a reg that wouldn't close it was immediately apparent on the chrono to see a variation depending on how quickly you took the next shot.

    Steyr regs have always been good and are still good out the box. Due to manufacture costs and time needed to get them to this point does not make financial sense.
    If you can make it more stable and faster responding then why not.
    The difference in pressure from start to finish (assuming that the creep stops like this one) is less than 10% almost 5%. We all know that 12fps spread in pellet speed does not make that much of a difference in POI at 55y. Will this give you more hits? don't know.

    Also the mental knowledge that your reg is fast and consistent is another tick in the "trust your equipment" box.

    I’d say a fair drop in POI at 55yrds

    If we have 3 regs set 5 bar apart we should be able to tell pretty quickly as we can now reg swap on the Walther with ease.

    That's a good plan I think we've got one coming that is set at 88 already most of the Ones here at about 83

    This one is being a bit cheeky I'm struggling to get a nice finish on the Face .
    my mate Errol told me about this but I haven't come across it until now .
    I wonder if there is a change of material ?
    we shall see ,I'll grind a new tool up and see how we get on

    Previous reg having been worked on and re-assembled. This will now go through the last stage of tuning and testing.

    This one seems to have caused some head scratching, but sorted now. You could say there was some hair being pulled out over it if it was anyone else doing the work. The difference between it's performance now and the other finished videos in the thread is achieved by the last stages.

    At the end the reg shows how it's fully closed. Any creep here would see the seal release and the air escape. Steyr regs work in a different way to most regs where the regulated pressure forces the valve closed... this means any leak back through here when there's just atmospheric the other side would allow the valve to open and thus release air. Quite a few other regs (Walther & Anschutz) use a system where the regulated pressure allows a valve to close by giving it room to do so... so them bleeding off after a cylinder is detached is not a sign of less than ideal performance because the valves are held closed by the pressure in the cylinder. It's for this reason you can see a pressure trend on regulators as the cylinder pressure alters the force on the valve which is being allowed to close.

    But for a steyr reg it's an indicator it's sealing and stopped creeping. That said I've not seen a Steyr reg come in that's managed it, new, used or fettled.

    Thats looking solid... very impressive lads.

    So the valve face just needs re finishing?

    It's not only that, but yes that's a core component. The standard of the finish needs to be really high as well. I think that's probably why the factory don't go there because it's quite intensive getting all the components just right. It's great when they just work. It's hours of work when they don't.
