I have never operated a router. For Christmas I got a Bosch PR20EVSK to use on craft projects. I make scroll saw collapsible baskets, scroll sawed bowls, trivets, boxes (recipe box, small bandsaw boxes), Christmas ornaments, etc. and an occasional whirligig for family members. I don't think I have worked with any wood longer than 18". Is it worth investing in a plunge base for the work I do?
