Many joints, mortice and the long-grain to long-grain bonding area The second factor is joint preparation. The mating surfaces must be smooth and clean (no dust or oil). They must also be close~fitting: None of the glues shown in photo 3 have gap-filling properties. Other factors are the amount of glue (most DlY’ers use far too much), the spreading method (use an artists brush), the open time before clamping, clamping pressure and clamping time. Be sure to follow the manufacturers instructions for best results.
All surfaces of a joint must be pulled up snugly. Make a special point of applying pressure across the long-grain contact area of a joint. Clamps put pressure on the tenon face/mortice wall interface. This is the long-grain to long-grain bonding area that gives a mortice and tenon joint its strength. The general rule should be: Use the ‘simplest’ joint that meets the appearance and strength requirements of the project you are tackling. If you are using an existing design you will probably use the same joints that the designer used. Reasons for not doing so include:
– You don’t have the skill or equipment to cut the specified joint.
– You believe the design is overkill and you want to substitute a simpler joint.
– You believe that the joint used is inadequate and you want to replace it with a better joint.
– You have equipment (for example, a biscuit cutter or dovetail jig) not specified in the project document and you want to make a better joint.
There certainly is the motivation to learn more about wood joints and opt for Reclaimed Barnwood for Sale even if most of your projects are made from somebody else’s plans. The two pieces of wood fall into two categories. There are those that are formed by a single saw cut (maybe subsequently planed or sanded) and are butted against their mating pieces. There is no mechanical interlock in such a joint and it has to be strengthened with glue or fasteners. In the second category the pieces are milled.
A rebate, dado, notch, groove or some sort of a pocket is cut in the pieces that are to be joined. This additional work (above that of trimming to size) creates varying degrees of interlock and often increases the long»grain to long-grain bonding area, resulting in a much stronger joint.
Most woodworking projects require multiple pieces of wood and thus one or more joints. A fundamental problem of design and construction is the selection of the joint/s to use. One school of thought says a woodworker should design around the construction design to accommodate the joints. Another says construct around the design – choose the joint to suit the design and style. In reality both approaches interact thanks to Reclaimed Barnwood for Sale.
