In the world of DIY and more specifically with regard to the manufacture of wooden furniture, the use of dowels or dowels is essential for their assembly.

But, why use wooden dowels to assemble furniture? We found several reasons:

  • Assembly using wooden dowels It’s too hard, although for cases where extra resistance is needed, it may be convenient to combine it with other systems.
  • Allows to be more precise in assembling the different pieces that make up the furniture.
  • Let’s do it hidden junctions, that is, where the method used to join pieces of wood is not seen.
  • Use wooden billets is a quick way to assemble a piece of furniture.

However, they also have a disadvantage: they are not the easiest method for beginners, unless you have a guide to drill and place the billets. On the other hand, although furniture is quick to assemble after machining, the planning of the spike may not be in complex cases.

Sizes and characteristics of wooden billets

As a general rule, we can buy wooden billets in three sizes: 6, 8 and 10 mm thick. The choice of one or the other size will depend on the wood we use and mainly on the thickness of the panel. The most common, although there is no written standard, is to use 6 and 8 mm bushings for 16 and 19 mm plates and 10 mm for thicker plates.

It is not difficult to find bits for these billets, as they are generally standardized measures.

Systems for joining with bushings

Regardless of the system we use to calculate points and drill, you will need to a drill (preferably with a guide to make sure that the resulting hole is completely straight). AN drill bit for wood the same diameter as the pin. Y a cap to mark the depth at which the drill will go into the wood (usually a ring that is adjusted with a screw and wrench, although some people also use some type of tape around the drill to see how far it should go).

Measure by hand and mark

The most imprecise, though not the least usual, is to use a pencil on the board to mark the points where the joints go and drill. Problems are frequent and basically we will find calculation errors in the marking and deviations in the drilling.

Despite these disadvantages, many woodworkers do not use other tools for most holes, but decide to simply measure and mark with their pencil to assemble furniture with wooden pegs.

For some more complex assemblies, it will be necessary to use a pin centering device or a guide. For do-it-yourself enthusiasts or beginners, I think they are essential.

Markers or pin centering devices

pin centering assembly

It is a small piece of metal with a tip that serves as a puncture to mark the location to be drilled. The use of the pin centering device is as follows:

  • The first part is drilled in the place where the assembly is to be carried out.
  • We insert the marker, the same thickness as the pin, into the hole we drilled.
  • We face the part with the marker with the other part that we have not yet drilled in the exact position where the assembly should be done.
  • We press hard or give a few strokes so that the centering device of the wooden pegs makes a small cut in the exact place where we should drill.

Spike guide or model

dowel guides

Today on the market there are many guides to assemble with wooden dowels, they are all types and prices.

guide for wooden pegs

The guides for simple and common consist of a plastic piece with a handle, where it is made, and at the end three slots with the most common measures and with different stops that allow to center the drill. These wooden peg guides are very simple to use and, above all, allows you to work quickly.
