Bascule Bridge

Notes:

The various units are first constructed then combined. The
bascules are attached to the uprights by means of locknuts. A
Semicircular Plate is attached to the underside of the 4½” x 2½”
Flexible Plate. This is simply to add weight to the plate.

Secure the operating cords to the Crank Handle by clipping a
Spring Clip over the cords. Crocheting yarn is ideal for all
Junior Models.
