Question: Dowels When Putting A Piece Of Plywood Together?

Should I use dowels to join wood?

The principle behind doweling is simple: small round but evenly cut sticks of wood, called dowels, are inserted into perfectly matched holes in corresponding boards that, when glued in place, provide a strong, durable woodworking joint.

What size dowels should I use?

Diameter: Ideally, the diameter of the dowel should be approximately 1/3 – and never more than 1/2 – of the thickness of the wood being joined. For example, if your product is 1” thick, you should be considering a dowel pin 3/8” in diameter. If your product is 1-1/4” thick, a 7/16” diameter would be more suitable.

How far apart should dowels be placed?

We recommend placing the first dowel at least 27 mm from the front and back. The distance between the pins is arbitrary. Remember that long distance between the pins usually means your joint won’t be strong enough. We recommend creating a distance of 65-100 mm.

Can I use dowels instead of screws?

Dowels and screws have different applications. In fine furniture, dowels are superior to screws. Dowels can be hidden inside the wood, and the heads of dowels, when exposed and sanded flush, can be almost invisible when the dowel wood is the same type as the entire project.

What are the disadvantages of a dowel joint?

The main disadvantage is that they are weak. When it comes to tenon and mortise joints, the face grain cheeks of the tenon are completely in contact with the face grain side of the mortise. The glue also holds best in this situation.

When would you use a dowel joint?

Dowels are used for making strong, accurate joints in wood. They are thicker and sturdier than nails or screws and therefore less prone to breakage. They provide a stronger joint than just using glue as they insert into both the pieces of wood being joined together. This means they cannot easily snap apart.

How strong is a dowel joint?

Test results show that dowels are the strongest method for creating this type of joint. The dowel joint in solid oak failed at an average of 650 pounds pressure, mortise and tenon joints failed at 500 pounds and biscuits failed at 325 pounds. Variations in the pressure at failure was less than 5 percent.

What is the weakest wood joint?

The butt joint is the simplest joint to make. It is also the weakest wood joint unless you use some form of reinforcement. It depends upon glue alone to hold it together.

Do dowels add strength?

With a dowel, both strength values are increased substantially. The increase will be related to the surface area of the dowel itself. Fourth, when two pieces are joined using side grain (not end grain) and the joint is made properly, this joint without dowels will be stronger in tensile strength than the wood itself.

Are wood joints stronger than screws?

Because the screws are toe-nailed at an angle into the wood, the joint is much stronger than a typical butt joint where the screws go directly into the end grain.
