I have some questions about Mortise and tenon joints and draw bores.
Paul calls the mortise and tenon the king of the joints, it’s a wonderful technique no doubt. Since making a few myself I find myself always looking at doors and window frames for its tell tail sign of good joinery. Searching for new and old hand made examples. I’m amazed at how common it is, new and old, all over the world! I’m in Peru now and whilst wondering around the 16th century churches I’m always drawn to the huge doors, pushing them open to check the massive joints (locals and tourists alike looking on mystified why this gringo is so engrossed with an old door).
Having watched Paul’s video on Draw bore mortise and tenons, I found myself looking for examples of this neat technique.
I’m from Australia and have never seen a door made with draw bore mortise and tenon there.
But in France I’ve seen many doors made with this technique, they often seem like older examples (also in their timber house framing it seems common). Also here in Peru it seems very prevalent even for new doors.
I wonder if anyone (or maybe Paul) could shed some light on the draw bore technique and it’s history.
Paul mentioned that it was common when clamps were expensive, is that all there is to it?
Perhaps it’s not as effective (to get a neat shoulder line) or more difficult? Perhaps not as strong or stronger? Maybe a tenon with 2 drawer bores would last longer then one just glued as over time it would hold up once the glue lines fracture?
Would you ever use the draw bore if you had a clamp big enough, why?
Is the drawer bore mortise and tenon still common for doors in Europe? Or perhaps only for hand tool enthusiasts?
Maybe it’s more common here in Peru where perhaps clamps are hard to come by?
Sorry for so many questions, perhaps an explanation will answer most. It’s all terribly interesting, craftsmen all over the world, spanning many centuries using the same technique! Where are they all now…
I like the idea that you can make a rock solid frame for anything without the use of clamps. I’m building the door for my tool box when I get home to Australia and intend to use the draw bore technique even though I have clamps.
