I'm trying to gather a little information on certain power tools for future purchases. One is the Craftsman router, model 27680, a 2 1/2 HP combo kit. What I'd like to know is has anyone used this in a table? Looking at it yesterday, it looks like even the plunge base could be used in a table and adjusted from above the table for height, due to a long threaded rod on it like the fixed base has. I'm also wondering if using the plunge base in a table and leaving it there will weaken the springs over time if I don't lower it back to its lowest setting when I'm finished with it. This seems common sense but I still wanted to ask. Completely unrelated to this, I have a pump shotgun I've owned for at least 16 years. It's remained fully loaded for most of that time and spends years at a time unused with the magazine spring compressed with shells in it. The spring has remained very springy and provides the needed tension in spite of this, so I just wondered if I'm worrying too much about the plunge base springs.
