STAY BOLT
The stay bolt passes through the main cam shaft bracket cap and screws into the column. The object of the stay bolt is to take the strain from the column. When the machine is in casting position with the pot locking against the mold, the mold and disk forcing against the vise, and the right-hand side of the vise locking against the stud, there is considerable strain on the column. If the column should spring, the vise would also move and the lockup would be imperfect. In applying the stay bolt, never tighten it with a wrench. If too tight, it will spring the bracket cap and cause the cam shaft to bind and the clutch will not drive the machine. Screw it in with your fingers until the head of the bolt bears lightly against the bracket.
