1. Begin by removing
1/2" (15 mm) of length
from the distal end of
the model to ensure
a flat surface for the
fabrication tooling.
The flat surface should
be perpendicular to
the long axis of the
cast in both planes.
2. Using a 3/16" (5 mm)
bit, drill a 1-1/2" (
40 mm) deep hole in
the center of the flat
surface of the model.
Drill 1-1/2" hole
3. Remove the Button Housing from the Fabrication Body.
4. Thread the Fabrication
Body and the attached
bolt into the hole drilled
in the previous step.
Position the Fabrication
Body so that it is flush
with the distal surface
of model. Make sure
the Fabrication Body is

alignment with regard
to the placment of the
Button Housing Recess.
5. Slide the Attachment Plate on to the Fabrication
Body so that the dowel pin in the Fabrication Body
engages the hole in the Attachment Plate.
6. The transition between
the Fabrication Body
and the model should
be smooth. Blend with
