How to: Making a Tube Rivet
Published: February 19, 2008
| Working on a steel block, use an awl to flare the opening of the tubing. Rotate the awl at a slight angle in a circular motion, using even pressure to work the metal. |
| To make the opening look like a collar, use dapping punches in a circular motion to spread the flared opening. Start with a small punch and then switch to a larger punch. |
| Use the curved back of a steel burnisher in a rocking motion to push the edges of the collar tightly against the surface of the component you are riveting, rounding them off. |
