Groove router cut .283 but copy router left tongue .241. The connection was very sloppy during assembly. The carbide wasn't ground to the same height on both sides, and there was too much paint on it before assembly, so the machined reference surfaces of different parts didn't touch. This kit does not come with gaskets or instructions.
