Hi - 3/8 should be fine. As a point of reference, most all pine 2x stock I've seen already has the edges eased with a 1/4" roundover:smile:.Wow, that was fast. My grandmother gave me the router when my grandfather passed away. Looks to be about 20 years old (Craftsman) and hardly used. I found a 3/8" roundover bit in the case. Thanks for the help.
