FABRICATION:
1.) Counter sink both holes for #10-32 flat head screws. (Use the cordless drill and clamp the base to the worktable).

NOTE: The counter sinks are deep enough when the heads of the screws are just below the surface of the base. Using the hand drill and the table vise are OK for this operation. Refer to the picture of a counter sink hole that is posted to the right of these instructions in the lab.
