Top half of axle sleeve being coped (grooved) so that the bottom gear shaft sleeve can be stacked upon it like a Lincoln Log. Single-point cutter is set to swing a 2.625 radius, to make the saddle come out correctly for the 5 1/4 inch diameter gear shaft sleeve to nest nicely into place. Several cuts were taken, each about .050 in depth. Between cuts, the head of the machine was lowered straight down to deepen the groove.
