Escapement

Parts

1 - Escapement frame (#27)
1- Escapement brace (#40)
4 - 1" dowels
2 - 1 1/4" dowels
Stops (assembled previously)
1 - Arbor sizing jig (#56)
2 - Nylon shoulder washers

Assembly Procedure

Using the same process that you used to prepare the 3 3/4" arbors, sand 3/4" of two of the 1" dowels
until they can pass through the arbor sizing jig. Then, continue increasing grits to sand the middle ½"
of these dowels. Finally, apply pencil lead to the middle ½" of these dowels.

With the escapement frame (#27) oriented as shown below, glue the two 1" dowels into the holes
shown, with the unsanded portion of the dowels into the escapement frame holes.

Flip the escapement frame over and

glue

the two 1 1/4" dowels into the escapement frame holes

as

shown below. Also, glue two 1" dowels into the escapement frame holes as shown below:
