Step-by-step guide

1. Preparation:

  • 1.1 Wear the required safety gear.
  • 1.2 Clean and degrease the installation area on the mast.

2. Marking and Drilling:

  • 2.1 Position the bracket on the mast. Beware of the lines and cables inside the mast.
  • 2.2 Use a measuring tape or caliper to ensure correct alignment.
  • 2.3 Mark the positions of the outer 4 corner holes of the bracket on the mast. Mark and drill the remaining holes when the bracket is firmly mounted.
  • 2.4 Select a drill bit slightly larger than the diameter of the rivets.
  • 2.5 Drill the holes at the marked positions. Use a depth stopper for the drill, to protect the cables in the mast.

3. Corrosion Protection:

  • 3.1 Apply a marine-grade anti-corrosion paste like Tef-Gel to the drilled holes and the surface of the mast where the bracket will be attached.

4. Attaching the Bracket:

  • 4.1 Align the bracket with the drilled holes on the mast.
  • 4.2 Insert the rivets through the bracket and into the drilled holes.
  • 4.3 Make sure nothing inside the mast is damaged.

5. Setting the Rivets:

  • 5.1 Use the rivet gun to set the rivets in place, following the manufacturer’s instructions for proper use.
  • 5.2 Ensure each rivet is fully set and the bracket is firmly attached to the mast.
  • 5.3 Now drill and rivet all remaining bracket holes.

6. Sealing the Rivets:

  • 6.1 Apply a small amount of marine-grade sealant or anti-corrosion paste around the heads of the rivets to provide additional protection against corrosion.

7. Final Inspection:

  • 7.1 Inspect the installation to ensure all rivets are properly set and the bracket is securely attached.
  • 7.2 Clean up any excess sealant to leave a neat finish.
  • 7.3 Verify the alignment and secure attachment of the bracket.

Additional Tips:

  • If the bracket is made of a different metal than aluminum, consider using a barrier material (such as a plastic or rubber gasket) between the bracket and the mast to prevent galvanic corrosion.
  • Regularly inspect the installation for signs of corrosion, especially in a marine environment, and reapply protective coatings as needed.
