Eduard has been issuing the world’s best photoetch for a long time now and I have watched many of my modeling friends use all sorts of things to add CA glue to the parts - toothpicks, dental tools, sprue parts and many more. The issue is how to apply the minimum amount of glue needed. Eduard has issued a nifty little tool to help apply the glue.
The parts come on a photoetch fret with 20 droppers. The droppers have a etched lower part and come to a tip with two small forks. Use is simple- cut the dropper free and make sure not to damage the tip. It is designed to fit into a #11 knife handle. Place it into the handle like a knife blade and tighten it up.
