Manually perform a mid-wood T-assembly

Difficulty level:


Necessary tools:

Wood glue. Sanding paper. A chisel with wood. A wooden pencil or a cutter. A folding workbench or vice. A saw with backpack. A clamp. A truscan or failing a flat meter.

The mid-wood T-joint is an assembly that joins the end of a piece of wood transverse to a piece of lateral wood of the same thickness at right angles. The mid-wood assembly therefore places the two pieces on the same plane, forming a completely flat surface, without any difference in height. This type of assembly has increased strength compared to a simple assembly by superposition. Composite clothing based on glue, it can also be reinforced with nails.

This assembly proceeding by covering is also called assembly mid-wood in angle. Finally, although it is also feasible singing, that is to say on the side of the least thick support, we will present here its most used version, flat.

Step 1: trace the shape of the cutouts to be made.

This first step is to delimit the areas of the cut that you will perform to prepare this type of assembly. Begin by reproducing the width of the part to be assembled on the upper face of the support. Depending on your preferences, you can make these tracings to be debited using the pencil or the cutter. For a good size layout, the simplest technique is to use directly the wooden cross to assemble as a standard, by juxtaposing it perfectly to the support. You just have to follow its edges in a straight line. Then continue with the width of the crossbar on both vertical faces of the support taking care to stop in the middle of its thickness and draw the tracing line horizontal line that connects the two previously drawn lines.

To delimit the cutting area on the part to be assembled, accurately transfer the width of the support from its end and draw a horizontal line on the underside, that is to say the face that you will cut later, and continue on the sides until half-timbered. Then trace the vertical line to the end of the room and continue tracing on the top face.

Once these cutting plans are done, you can go to the cut.

Step 2: Make the cutting half-wood on the part to assemble.

With the saw, place yourself on the path of the end that divides the thickness of the piece to be assembled and begin cutting. For a good result, saw straight up and hold the pieces firmly when making cuts by using either a folding bench or vice.

Then cut the thickness to be cut against the grain. The room is now ready to be assembled.

Step 3: operate the cut half-timber on the support.

For the cutting of the area that will receive the assembly on the support, start by sawing vertically one of the demarcations of the upper face by stopping mid-wood, then before cutting the other demarcation, make one to two additional intermediate cuts to facilitate future work with chisel.

Bring the chisel and mallet to cut the depth. To do this, proceed progressively from both sides, in the direction of the threads, from the surface to the horizontal line drawn mid-wood.

Before moving on to the next step make sure both pieces fit together. If this is not the case and they are struggling to assemble, do a light sanding, check and start again if necessary.

Step 4: Paste the assembly.

Once the cut-outs are complete, quickly clean the parts to be assembled by removing the dust produced with a cloth, a broom or by blowing. Surfaces must be clean to stick well. Glue the hollow part of the support and proceed to assembly. Hold everything firmly with a clamp for the time it takes for the glue to dry. To avoid damaging the wood with clamp marks place martyrs, folded sheets of paper or pieces of cardboard, between the contact points of the clamp and the wood. Also, be sure to wipe off the remaining flush glue. If you want to add an additional nail siding, run it before the glue picks up.
