Learn to live with these types of error it’s woodworking not major highly significant engineering measuring .I wish you well but lighten up some and actually if you don’t you’ll never make anything with a perfectionist attitude it will only make your life a misery, when the object is to enjoy your woodworking
The best example comes from Frank Klaus a great woodworker ,who said don’t spend all day measuring and marking out dovetails if there are gaps fill them in with sawdust and glue no one will know. Alistair
