Hi T, can you post a pic of those eyes???
If they are domed with a flat back and you want to countersink them in the plug you will need to use a "brad bit " for your drill the same diameter as the eyes. Then what I do is drill a hole where I want the eye to be deep enough so that the edges of the eye are in the plug. I use a small dab of GOOP to glue the eye in place. It's a snug fit if you match the bit size to the diameter of the eye and looks professional.
Hope this helps.
Good pluggin,

P.S. Where are you from in W. Mass?, I grew up in Holyoke
