I am making a Tele body from scratch, which means gluing two boards together. My dilema is this...when I glue the boards together, there will be a small gap in the boards. How do I fix that...do I use wood filler or do I try to get the sides as flat as possible? As far as strength goes, what type of glue should I use, and should I use dowels to strengthen it? I've never done this before and any advice would be appreciated. Thanks in advance.
