QUOTE: Originally posted by JimValle When spinning an engine, speed isn't the only issue. The engine should be sitting exactly over the center of the table, or so that there's equal weight on each side of dead center. If the engine was not proberly centered a mechanical turntable had to strain to move it and an "armstrong" turtable couldn't be moved at all.
QUOTE: Originally posted by ardenastationmaster One measure of speed is the pecentage of a full 360-degree revolution per minute, and the other is the speed of one end of the table along the edge of the pit in miles per hour. Thus you would have an RPM, and an MPH, figure for the table.
