THROUGH
As you can see from the picture it’s very similar to the above.
The only difference lies in the fact that the mortise is a real through-hole and the tenon arrives flush with the rear face of the workpiece.
Usually the tenon is made slightly longer than necessary and the excess part is then cut flush to have a smooth and homogeneous surface on the other side.
THROUGH WEDGED
In this case, the tenon is not cut flush, but is enhanced and highlighted making it protrude a few centimeters.
Furthermore is punctured so that, by inserting a wedge , the joint locks without needing adhesives.
Precisely for this reason the junction is also removable .
Very frequent use of this joining parts of tables, chairs and benches .
BAREFACED TENON
No no, I do not mean to offend anyone.
Nor poor tenon which will be our job partner for a long time.
In this case it’s said barefaced because it has only one shoulder and is therefore decentralized.
It is used mostly for the production of chairs .
BLIND WEDGED
The Blind Mortise, instead of having the classic rectangular shape, is made wider than the tenon and with an inclined face .
In this way it’s inserted inside, near the tenon, a small reinforcing wedge that stabilizes the union giving more resistance .
FOXTAIL WEDGED
This interlocking Tenon-Mortise is realized mainly in the case of wood that are subject to strong dimensional variations . (remember WOOD IS A MATERIAL VIVO )
We practice a passer Slotting and a Tenon with double-edged “V” in which are inserted two wedges which can then be adjusted to the need at the moment when the timber will deform.
BRIDLE
It is the most widely used junction in the construction of frames for paintings.
The mortise is located at the end of the piece and, therefore, has an open face in which the tenon is inserted as in a channel.
HAUNCHED
The Tenon presents a sort of “step” which makes it more resistant to mechanical stresses.
Of course, the Mortasa will have the same shaping.
PINNED
I’ve already talked about
pinning in the Article related to
joints .
It’s a fairly basic type of junction. In this case, we need to give more strength to our through Tenon-Mortise .
As you can see from the picture, on the Tenon’s and on the workpiece on which is located the Mortasa, a hole into which is inserted a is practiced plug (a small wooden cylinder).
This interlocking is considered virtually unbreakable .
BLIND DOUBLE
One of the most difficult variants to achieve .
You have to shape in a perfect way the two parts of the union to have a very solid and durable joint.

AT WORK!
Well!
Now you just have to arm yourself with patience and
proper tools and immediately start to practice.
It’s ESSENTIAL to have good results in joinery.
