    A picture of the updated Diana piston with the new crimp.

    I thought some of you guys might like to see this pic that has been posted on the DWC, the original crimp is also a bit deeper by .020"

    That looks like it might have been made in China.

    Many years ago.

    If the groove in the piston rod is where the original crimp is then the second crimp is likely to make it more unstable
    Stupid Idea I reckon !
    ( hope I don't have to explain )

    I wonder if the piston rod is now longer.

    I think it's a pretty bad idea in the first place using a crimps to hold the whole thing together, would the deeper crimps and the new crimps make the piston even more out of round? (yet another problem they've had) surely they should realise that the metal has to go somewhere when it gets compressed and it doesn't always go inwards.

    Far too many rifles to list now, all mainly British but the odd pesky foreigner has snuck in

    I really wish I hadn't seen that Barry.

    After turning god knows how many rifles out with iffy pistons, they've now decided they need to crimp them a little harder ??

    Looks like someone on work experience has "had a go"

    On the list of top ten attempts to bodge a cure, this has pipped HW's 99"cure" by a fair margin.

    Certainly put the lid on me owning another Diana.
