    Today I visited my brother in law who just happened to have a motor bike piston lying around and we were able to give the tool a run. As you can see from the photos it was perfectly capable of expanding this small ring for removal and replacement. By pressing the ring into the groove on the opposite side of the piston we were able to make the ends stick out far enough to get hold of them with the jaws of the tool, expand it and lift it off. My BIL did the work while I took the photos and he did comment that the handles are not all that user friendly.
    So I'd have to say that it does work better as a piston ring expander than it does as a wire stripper, so now need to find some old rubber sheathed wire so we can give Fletty's theory a run.
    Cheers,
    Geoff.

    Pretty convincing demo, Geoff. I think I'm converted, after being highly skeptical when it was first mooted...

    I agree, but it would be nice to find Jason's patent just to get his/her confirmation of purpose and the era.

    Me too, I didn't realize that the jaws were so small. Was the motorcycle running a little rough?

    It would have been Rob, before he got his hands on it, but I can assure you that by the time he's finished with the old Trumpys and BSA basket cases, they're gleaming and running ever so sweetly.

    Hi Gang, a quick update. I, along with others, of the HTPSWA have attended events of one kind or another every weekend this month and I've taken the mystery tool out for a run at each of them. We cannot get agreement on the purpose of this tool. I would say that 45% say wire stripper, others think circlip pliers or spring stretchers. When I suggest piston ring expander some like the idea others reject it out of hand. Dozens have taken photo's and said they'd let me know the answer.... so far non have rung back.
    Cheers,
    Geoff.

    Guess what?
    A JASCO automotive tool catalogue from 1930's has just popped up on ebay. Hows that! I wonder if the pirston ring popper is in it?

    Good one Dick, you might be onto something there.
    Cheers,

    Hi Geoff,

    thought I might give this thread another kick.

    If you and any one else who is still curious,
    go to the HTPAA website and look under Tools / Whatits / #25
    you'll see the result of my submission of my tool, which is similar to yours.

    Regards

    Graham.

    Thanks Graham, one thing I've learnt with the mystery tool at a public event is to not make any suggestions as to its purpose. That way viewers have an open mind and aren't smokescreened by me saying "some people suggest...."
    I think it's an Australian tool because I put it on a UK forum and didn't get a definite ID and I don't think it's American as there is so much US tool info available that someone would have found it by now.
    Doggie's suggestion of JASCO is a promising lead but I've hit a blank wall there too.
    I did contact the seller of the JASCO catalogue and asked if the tool was shown in it, unsurprisingly they didn't reply........(ha ha buy the catalogue and find out for yourself you cheapskate)
    Cheers,
    Geoff.

    I think this is a pair of wire stripper... The copper wire stripper can be used for cooper stripping, wire cutting, copper wire recycling and for all electrical purposes for household needs.
