Below is a method I use to make eyelets for sails.
1. place brass tube in drill and cut to length using mini tube cutter.


2. place eyelet blank on firm metal surface and using a tungsten carbide punch, taper one side.



3. Flip over and repeat punching operation. The completed item now has a middle radius that your rope can be attached to that wont slip off.

Note if you want to blacken the surface with brass black be sure to emery /sand the surface prior cutting.
