Modeler's Moment - Making push rods turn corners

Bell cranks on turnout push rods

Turnouts that are far from the operating aisle can sometimes require some special treatment to use manual turnout controls. If the control can be mounted in line with the throw bar, a simple push rod is all that's needed. But if the turnout is at an angle other than perpendicular, you will need to use something like a bell crank to change the push rod's direction of travel. The crank can be made very simply with a scrap piece of brass sheet like we see on this HO scale layout. For this purpose, brass is more highly recommended than thick styrene because the holes in the styrene where the push rods attach will wear out much too quickly. If you're not adept at working with brass, check at your local radio control hobby shop for commercial bell cranks.
