11) Slide the minute pipe (installed in 32-tooth gear) onto the great wheel arbor (it should fit loosely
on the arbor). The 32-tooth gear mates with the 8-tooth gear. Push a set washer onto the arbor.
Maintain a small amount of clearance between the set washer and the minute pipe so that the 32-
tooth gear can rotate freely on the arbor. Finally push the minute hand onto the arbor. It should be
tight enough to hold its position, yet be able to rotated to a new position (the hands cannot be glued
to the arbor). If either of the hands is too loose (causing the hands to slip), apply a small amount of
glue to the shaft to build it up slightly. Allow to dry completely before attaching hand. If the hands
are too tight, sand the shaft or interior hole of the hand.
12) Attach the second hand to the escape wheel arbor protruding through top of front frame. It
should be ‘friction fit’ like the other hands–not glued.
13) Place the dial on the front frame, centered on the great wheel arbor (look at the great wheel to
help find the center position. Mark the dial’s location on the frame. Glue the dial in place.
