| Eyelet Forming Process |
Tooling Requirements |
1. Apply firm, even pressure using the flared end of the setting tool to flare the eyelet barrel. |
2. Apply firm, even pressure using the flat end of the setting tool to flatten the eyelet barrel. |
To form and set eyelets by hand, you will need the following tooling:
(2) 115-3120 Setting Tool, Small
(1) 115-3122 Tool Base
(1) 115-3145 Tool Grip
To set eyelets using 110-5202 Eyelet Press, you will need the following tooling:
(2) 115-3120 Setting Tool, Small or (2) 115-3126 Setting Tool, Large |
