Joining two boards perfectly together has never been so easy and convenient, not until the use of a dowel jig. Every woodworker must agree; that using a dowel jig creates a secure and highly strengthened joint that’ll keep your boards together for a long while, most likely forever if properly fitted.

Dowelling involves creating pegs that fit perfectly into holes – fitting them perfectly together is the only possible way to keep two or more pieces of wood together. A dowelling jig is the best tool to use if you’ll be making a lot of dowels to join two boards together – for accuracy and precision. Although there are other ways to go about this, like plastering, using pocket screws or biscuits, however, using a dowel is undefeated.

Buyer’s Guide for Dowel Jig

Before getting to know how to use a dowel jig, you should know what to look out for, just in case you’re purchasing one or renting one. One of the best ways to successfully use a dowel jig is knowing its abilities and disabilities. With this brief buyer’s guide, you’ll gain sufficient knowledge of the dowel jig. Sufficient enough to make the right decision.

Below are some of the factors to consider when choosing a dowel jig;

Bushing size

The type of project you’re working on is dependent on the bushing size of your dowel jig. If you work on a variety of projects, without being sure of what project you’ll work on next as a professional woodworker or a DIYer with a diversified portfolio, purchasing a dowel jig with various bushing sizes is the best choice to make.

Material

While using a dowel jig, there are high possibilities that it’ll fall a couple of times, or you might bump it on your workbench or the wall while moving it. Falling and bumping your dowel jig against another object is inevitable, and the only way to reduce the damages it might cause is purchasing one with a rigid body construction.

Aluminum and stainless-steel dowel jigs are known to be sturdy, adding to its durability. It is best to purchase a dowel jig made out of these materials to prevent frequent repairs or total replacement. If you’re purchasing an aluminum dowel jig, there are high chances of seeing signs of corrosion, so you need to be extra careful when handling it, unlike the stainless-steel dowel jig, which is resistant to corrosion.

Versatility

Another feature to look at when looking for the right dowel jig to purchase is its versatility. You don’t want to have more than one dowel jig just because the previous one you purchased can’t perform specific tasks.

It is best to purchase one that can be used to carry out a variety of projects effectively. Put into consideration the number of connections it can create, the type of connections, and its ability to work on different sizes of wood.

Self-centering

Purchasing a dowel jig that automatically aligns your dowels and holes for a perfect fit is essential for a strong and effective joint – it saves time, stress and, money. Most times, the accuracy of your dowel jig is dependent on whether it is self-centering or not.

Accuracy

The accuracy of your dowel jig is more important than you think. You may end up finding it difficult to fit your bushings into the drilled holes – this isn’t totally dependent on your skill level, but the accuracy of your dowel jig.

Getting yourself a good dowel jig will eradicate all forms of loose holes or oversized bushings. Precision is key in dowelling, and only a good dowel jig will make sure of that.
