    How to change the backset of a deadbolt latch.



    Aluminum boat rivet repair can be easy, fast, and permanent with Super Alloy 5 aluminum rod and flux, and an oxyacetylene torch. YOU CANNOT USE PROPANE ON ALUMINUM BOATS, THE PARENT METAL WILL NOT GET HOT ENOUGH. YOU CANNOT USE SUPER ALLOY 1 ON ALUMINUM BOATS, IT IS NOT HOT ENOUGH.

    The boat pictured is riddled with holes, and the owner had used epoxy to try to fill said holes. Because the epoxy or silicon didn’t last long, the boat owner put his boat up for sale.

    We removed the silicon with an angle grinder with a sanding disk, and used an oxyacetylene torch with Super Alloy 5 rod and flux to properly fill the aluminum holes. Super Alloy 5 aluminum brazing rod made easy work of the once leaky rivet.

    Note: Flexing the aluminum while in use can cause the rivets to loosen over time. After brazing with Super Alloy 5, the area around the rivet is stronger than ever–and the flex is removed from the rivets.

    After allowing the area to cool naturally, we used water and a wire brush to remove the flux. When you want to repair this area only once then brazing, welding or soldering will always be your best option.
