Mortice & Tenon

David Charlesworth’s new Mortice & Tenon course

One tends to think of mortice & tenon joints as being simple, perhaps because they are one of the first joints which we come across at school or at home.
My experience shows that they are a demanding joint to get right. I think very few of us have the skill to saw tenon cheeks accurately. We will therefore explore more precise methods of ensuring a good fit. If the surfaces do not line up, a large amount of tedious remedial planing will be necessary. A specially planed up test stick is an invaluable aid to alignment.
I have methods for haunch fitting which are a good deal more accurate than the techniques shown in text books.
We will look briefly at the hollow chisel morticer but I hope to demonstrate that hand cut mortices can be every bit as good. Although I don’t chop mortices very often I’m amazed at the quality we can achieve with a good mortice chisel.
Draw bore tenoning is another aspect which we can try. I have the Lie-Nielsen dowel plates which produce very nice pegs if some preparatory rounding is done with a plane.
Wedged tenons will also be covered and I have a clever (and safe) jig for producing wedges on the bandsaw. Joints with mitred shoulders are another topic.
At the end of this course you will be much more confident with these fundamental joints.
