i use screw eyes pretty much excluesively.have not had any problems with them pulling out thus far.here is how i set them.first off,i would suggest only using stainless steel screw eyes.they are way stronger than the nickel plated crap.i counter sink the plug with an aul,or a nail,then drill a pilot hole.i think i use a 1/16" bit for the pilot hole.i then counter bore the pilot hole.i drill it at least twice the width,and half the depth of the screw eye used.for saltwater plugs i mostly use one inch .072 diameter screw eyes.but if you really want to make sure they don't budge,you can use the one and a half inch .092 diameter screw eyes.i then fill the hole with 5 minute epoxy.you don't have much working time with this stuff so if your doing several plugs i'd keep it to two,or three screw eyes at a time max.when the mix is still wet,insert the screw eye.once it has set up,i mix another batch of 5 minute epoxy up and dab some around the area where the screw eye,and the wood meet.when the screw eyes are set in this fashion,you have half of the threads epoxied,and embedded in the plug.and the other half of the screw eye incased in it's own plug of epoxy.
when i first started using this method,i asked bassmaster to stress test a couple of plugs i made on some bass in his area.if they held up to the sized fish he catches,and the abuse that lad puts on a plug,then i know they'll hold up to the dinky sized fish i usually catch.
