      If you folks ever get a chance to attend the Cabin Fever Expo in York, PA, there are always several functioning teeny engines that are just mindblowing. There

        If you folks ever get a chance to attend the Cabin Fever Expo in York,
        PA, there are always several functioning teeny engines that are just
        mindblowing.

        There was an older fellow who had made several miniature radial engines-
        with pistons about 1/4" diameter or smaller- complete with rings! Amazing.

        Still, this V12 represents some excellent miniature machining.
