Trimming the Horns:

Servo horn come in various sizes and shapes.  Some servo horns may require trimming to fit with the Mini Pan-Tilt Kit.

• The two unmodified horns in the center are from a Tower SG-92 Servo.
• The two horns on the outside have been trimmed to fit the Pan-Tilt kit.

The photo on the left shows the area that needs to be cut away to fit inside the pan-tilt base.  The excess plastic can be easily trimmed using a sharp hobby knife, or a pair of wire cutters.

• Insert the servo into one side of the pan bracket.
• Make sure that the servo shaft is at the opposite side from the pivot point for the tilt bracket

• Assemble the second side of the pan bracket to enclose the servo.

• Attach the two halves of the pan bracket using two screws as shown.

• Attach the 4-armed servo horn to the servo shaft using one of the short screws as shown.

• Attach the base to the servo horn, using 4 of the smallest screws as shown.

• Mount the servo so that the shaft alingns with the pivot hole and attach with the two screws as shown.

• Fit the single-armed eservo horn into the recess in the pan-base and attach it with one of the smallest screws.

• Align the servo shaft from the tilt bracket with the hole in the servo horn.
• Snap the tilt bracket into place, using a small screwdriver as a lever to lift the pivot hole over the pivot pin on the tilt-base.

• Complete the assembly by securing the horn to the shaft with a short screw.

But what about the leftover parts?

When you finish assembling the kit, you will have several machine screws, nuts and threaded inserts leftover.  These can be used to attach the base to your project.  Or you can save them in your parts-bin for future projects.
