    Default What could this piston be out of?

    Hi Guys, In a moment of weakness I purchased this piston from Grays online, but the vendor knew nothing about the origins. Any ideas on what this might have been out of? It's 412mm in diameter, 603mm overall height with a 140mm diameter gudgeon bushing.
    Thanks for any help.

    Default Why?

    Just as a matter of interest, if you don't know what it is out out then presumably you have no use for it. Why did you buy it?

    If I followed that advise I'd have more money in my pocket and a lot more space in my shed.

    It is definitely out of a vintage model aircraft engine.

    no idea what it's out of

    definitely not from the average suburban lawnmower

    But a bit of glass 2" to 3" to more" bigger in radius and what a great side table !

    wish I had one ...

    It could be out of an old stationary engine. I have a 67Hp 1924 Ruston Hornsby engine with only a slightly smaller piston. These were single piston engines that often drove large irrigation pumps and mine is by no means the largest. The overall engine weighs about 10 tonne with flywheel about 4 tonnes. The muffler weighs more than a tonne. When I moved mine there was an even bigger engine only a km down the river. But could just as easily be out of a large marine engine.

    Regards Mark
