The Quarterer II NorthWest Short Line

Quartering is the term for setting crankpins of locomotive drivers at 90 degrees ‘crank’ apart (similar to an automobile crankshaft). Accurate quarter of all drivers in a set to the same angle (whether exactly 90 degrees or not) is critical for smooth operation of model locomotives. This tool enables quick, accurate quartering of HO, Sn3, S, and On3 drivers up to 1-1/2" (39mm) diameter (120" in HO scale, 90" in S scale, 65" in O scale). Minimum crank throw (distance from axle center to crankpin center) is 0.150" (3.81mm).  The wheel is located onto the axle while the wheelset is securely held in the tool avoiding possibility of slippage. Can also be used to compare quarter of existing driver sets.
