Thats another possibility Andy, but that one, levered out to flip this bit of Mahogany, would have to be pretty stout in order to make its 45 degrees move the gauge close to 120 degrees. Its 3/8" thick, 1.75" wide, and about a foot long, swinging on a stick of piano hinge about that same length. Currently lays flat on the top of the white ash clamping platform when in the use position, or flips back out of the way by about a 170 degrees total turn of the piano hinge. Thats one of the reasons I was looking at a teeny double acting air cylinder with perhaps a 3" stroke, or the cd tray gear assembly mounted out on the end of the table with a plastic hose serving as the relay medium from its final reduction gear to a 1/4" dowel set into the end of the stick, near the hinge, driven by a geared way down tray motor assembly would adequately handle the axis of rotation miss-alignment caused by the dowels small arc motion. That would, by the time I got it boxed up for swarf & saw dust shielding, be about the width of the table, an inch thick and 2" tall at the axel output just to get it pointed at the stick. Seems like a lot of box for what I want to do. Would some pix help? Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
