  • Page 32 Place a spacer washer (#49) onto arbor #1 prior to placing escapement onto arbor #1. After the escapement is installed on the arbor, place a set washer (#34) onto arbor #1, leaving a small amount of clearance between the set washer and the escapement so the escapement can pivot freely. Glue a nylon shoulder washer into both faces of the entry pallet arm (#28) and both faces of the exit pallet arm (#33).
  • Page 33 Connect together the front and rear frames, making sure the pillars, dowels, and pendulum support plates all engage in their corresponding holes. Drive a #4x1/2" screw into the predrilled hole in each of the three pillars to secure the pillars to the pillar anchors.

  • Page 34: Mounting And Adjusting

    Mounting and Adjusting 1) Determine the location to hang your clock. Be sure to consider the following: a) The clock must be mounted securely to the wall. Locate a stud within the wall for the solid mounting. b) Choose a location which is free from obstructions to the swinging pendulum or the descending weight.
  • Page 35 5) Turn the screw in the escapement stops so they are oriented as shown in the diagram below. The stop on the left is turned so the rim farthest from the screw is down; the stop on the right is turned so the rim farthest from the screw is to the right.
  • Page 36 The escapement stops control the engagement point of the pallet and the escape wheel teeth. For both pallets, the goal is to have the tip of the escape wheel teeth contact directly with the corner of each pallet, as shown below; there should be no sliding of the escape wheel teeth along the pallet faces. Rotating the escapement stops will change the contact point by stopping the pallet earlier or later.
  • Page 37 Final Gears and Hands Parts 1 - 8-tooth gear (#29) 1 - 30-tooth gear (#39) 1 - 1 ½" dowel (prepared previously) 2 - Set washers (#34) 3 - Spacer washers (#49) 1 - Minute hand (#24) 32-tooth gear with hour pipe (previously installed) Assembly Procedure It is not necessary to remove the clock from the wall to perform the next steps.
  • Page 38 Winding Pull Parts 1 - Winding pull middle (#15) 2 - Winding pull faces (#53) Assembly Procedure 1) Hold the winding pull middle piece (#15) between the two winding pull side pieces (#53). With the pieces held together, sand the perimeter if desired and then apply finish as desired. 2) With the clock mounted on the wall, wind the clock fully by pulling down on the rewind cord with your left hand while simultaneously raising the weight with your right hand (it might be necessary to wrap the cord around a piece of wood in order to maintain a solid grip on the cord).
  • Page 39 Dial Parts 1 - Dial (#2) 12 - Dial markers (#42) Assembly Procedure If desired, sand the edges of the dial (#2). If desired, stain the dial markers (#42). Glue the dial markers (#42) into the holes around the dial, setting the markers flush with the dial face. Apply finish to the dial if desired.
  • Page 40 Adjusting and Regulating 1) Setting the time The hour and minute hands need to be set independently. Both hands should be friction fit on their shafts so that they can be rotated. If the hands fit too tightly, it may be necessary to grasp the great wheel when setting the hands to prevent the entire motion train from moving.

  • Page 41: Troubleshooting

    Troubleshooting If the clock fails to operate properly, refer to the suggestions below. Gear Train Will Not Advance If the gear train will not advance when weight is applied to the weight cord, check the following possible problem sources. If you are having difficulty with the gear train, it might be easier to troubleshoot if the escape lever is moved out of the way to allow free movement of the gears.
