Thanks for this Sebastiaan. For those who do not know him, Charles Hayward was well known years ago. He Edited a journal called “Woodworker.” I have not seen it but a rather pricy compilation of it has been put out by Chris Schwarz and is available on Lee Valley. I bet it is worth looking at. But I know him through his very nice book Woodwork Joints. It is long out of print, but I picked up a very used copy on Amazon a while back. It is nice to see another book by him.
