How to Remove and Replace Aluminum Tubular Rivets: A Comprehensive Guide

In the realm of DIY projects, working with tubular rivets is an essential skill. Aluminum rivets, in particular, are commonly used in aircraft construction, furniture assembly, and other demanding applications. Their strength and resistance to corrosion make them an ideal choice for heavy-duty fastening. However, when it comes time to remove or replace these rivets, it can be a daunting task without the proper knowledge and tools.

Understanding Tubular Rivets

Tubular rivets consist of a hollow cylindrical body with a solid mandrel inside. When installed, the mandrel is pulled through the rivet, causing the rivet body to expand and form a bulb-shaped head. This expansion provides a strong and permanent mechanical joint.

Removing Aluminum Tubular Rivets

To remove aluminum tubular rivets, you will need the following tools:

Drill with a bit slightly smaller than the rivet diameter

Center punch

Hammer

1. Center punch the rivet head: This will create a guide for drilling.

2. Drill out the rivet head: Drill slowly and carefully, avoiding damage to the surrounding material.

3. Remove the mandrel: Once the head is removed, the mandrel can be pushed out with a punch.

4. Pull the rivet body: Use pliers or a rivet remover to pull the rivet body through the hole.

Replacing Aluminum Tubular Rivets

Replacing aluminum tubular rivets requires similar tools and a few additional steps:

Choose the correct rivet size: Ensure the new rivet matches the diameter and length of the previous one.

Clean the hole: Remove any burrs or debris from the hole.

Insert the rivet: Place the rivet in the hole and tap it lightly with a hammer to seat it properly.

Pull the mandrel: Use a rivet gun or hammer to pull the mandrel through the rivet.

Form the head: Continue pulling the mandrel until the rivet body expands sufficiently to form a bulb-shaped head.

Tips and Tricks

For hardened or stubborn rivets, use a diamond-tipped drill bit or soak them in penetrating oil before drilling.

Wear safety glasses and work in a well-ventilated area.

Practice on scrap material before attempting to remove or replace rivets on your actual project.
