Approach for creating rabbet/groove in mirror frame
I’m attempting to construct a mirror frame using 1 x 3 wood. What I’d like to do is make rabbet cuts on the inside of the wood frame so I can drop the mirror into that channel to secure it.
What’s the best way to make rabbet cuts for that? Ideally I’d like the channel to have a depth of 1/4″ (same thickness as mirror) and a channel width of 1/2″ on two sides, and 1 1/2″ on the other two sides. Seems to me I need a router and rabbeting bit, but I don’t think most bits will make anything wide than 1/2″. Any suggestions for how to get the channel width to 1 1/2″?
