Replace a Die-Inserted Grommet
A die-inserted grommet (Figure 4, Item 1) consists of two brass parts. The male half, called a barrel
(Figure 4, Item 2), is smooth. The female half, called a washer (Figure 4, Item 3), has spurs that grip the
fabric.
1. Position fabric (Figure 4, Item 4) face up on end grain surface of softwood lumber.
2. Using a size 5 cutting punch (Figure 4, Item 5) for a size 4 grommet (or a size 6 cutting punch for a
size 5 grommet) and a rawhide mallet (Figure 4, Item 6), cut a grommet hole in the fabric by hitting
top of cutting punch with rawhide mallet.
3. Insert grommet barrel (Figure 4, Item 2) into hole of fabric (Figure 4, Item 4) from the underside.
4. Place fabric (Figure 4, Item 4) and bottom (flat) part of grommet barrel (Figure 4, Item 2) on
grommet die (Figure 4, Item 7).
5. Place the grommet washer (Figure 4, Item 3), spurs down, over grommet barrel (Figure 4, Item 2).
6. Insert cutting punch (Figure 4, Item 5) into grommet barrel (Figure 4, Item 2) and hold in place.
7. Hit top of cutting punch (Figure 4, Item 5) with rawhide mallet (Figure 4, Item 6) hard enough to
clinch the parts to fabric (Figure 4, Item 4) without damaging grommet (Figure 4, Item 1) or fabric.
When parts are clinched properly, the edge of the grommet barrel (Figure 4, Item 2) has a smooth
roll.
