V-Grooves Keep Squeeze-Out In Check
When I glue trim molding in place, I don't want any glue squeeze-out because it's impossible to clean it out of molding crevices. To keep glue squeeze-out in check, I use a V-groove bit in my table-mounted router to cut shallow grooves in the back side of the molding as shown above. Then, I apply a thin bead of glue between the grooves. When I install the molding, any excess glue collects in the grooves.
