A while back there was a thread round the tenon or square the mortise? Opinions were mixed. I know how to square a router-made mortise with a chisel, but I'm not sure the best way to round a tenon cut on a table saw. (I am not looking for a totally round tenon like on a chair leg; just a rectangular tenon with rounded ends to fit into a round mortise.)
Hand file and sandpaper? I can imagine using a roundover bit, but I don't have a router table I think it would be tough with a handheld router.
thanks.
