Dowel Jig Buyer’s Guide
For the past several years, the dowel jig has been an integral part of woodworking. It’s an effective and discreet way to strengthen joints where a nail cannot go. This job is often time-consuming and complicated without the use of a dowel jig, which is why it’s crucial for every woodworker to have access to a top of the line model. Below, you’ll find a list of the benefits that come with adding one of these tools to your woodworking arsenal and how a dowel jig can be used.
Benefits of Dowel Jigs
- When you use a dowel jig, there’s no need for nails, screws or other equipment.
- Using a dowel jig ensures a neat finish
- Dowling is considered a fast and simple process
- Dowel joints are considered the toughest types of joints for woodworking, especially if there are multiple rows of dowels.
- A doweling is a technique that’s used in woodworking where a couple of wood pieces are attached by a wooden pin or dowel. In the pieces of wood, a pile is carved where the dowel goes.
- Dowel joints remove the need for hardware, which helps to reduce the type of injuries that often occur when working with hardware. However, it can also help to give a finished project a clean look since there’s no disruption to the grain pattern.
- You’ll not only get a beautiful finish, but a strong joint. The pin runs inside of the wood, improving joint strength. This level of strength is much better than what you’ll get from using nails or wood glue to attach the wood.
- A dowel joint is used in a flat or right angle because it’s the best choice for complex joints. The dowel joints can be used in metal work and concrete construction.
Below, I’ll go over the important features to look for in a new dowel jig, how these features impact quality and performance, and how to pick out the perfect dowel jig based on application and your woodworking needs.
The bushing size will determine what types of jobs you can do, so it’s important to ensure you purchase a model that supports the type of projects you normally complete. If you’re doing the same types of connections in the same type of wood frequently, then you won’t need a dowel jig that’s versatile. On the other hand, if you’re not sure which types of jobs you’ll be doing in the future, then you’ll want to buy a model that features a variety of bushing sizes so you can move forward with the next job without having to purchase a new dowel jig. The most common three size options include:
These sizes will be sufficient for most jobs, but if you’re working with very small or very large pieces of wood then you may need to invest in a dowel jig that’s smaller or larger than these standard sizes.
Getting a dowel centered is crucial to getting a good looking, strong, and flush connection. If the dowel is off center, then you’ll run the risk of splitting the wood or you may get a connection that isn’t flush, which means that you will be forced to take it apart and redo the pieces or sand down the edges. This can be a very time-consuming and expensive mistake to correct, so be sure you invest in a jig that makes centering the dowels a fast and simple task.
Many models are advertised as self-centering. This basically means that they use a screw to draw both sides of the jig toward the board as the user tightens it. Essentially, this results in the hole centered perfectly, however, there are some problems with this process. Any manufacturing flaws that impact the thickness of the two sides can result in the sides meeting the wood at the wrong angle. This will throw the alignment off. Additionally, holes that are not correctly drilled in the jig itself can lead to a similar problem.
The type of materials the dowel jig is made out of matters. Aluminum is one of the most common materials used due to its intrinsic strength combined with its light weight, which will make it easy to haul around and attach to wood. Unfortunately, aluminum has a major flaw. Untreated surfaces are often vulnerable to rust and corrosion. The surface may be treated to address this issue; however, most manufacturers do not use a corrosion resistant coating on their dowel jigs.
Basically, you can either spend a little more and get a steel-plated model or take special care of an untreated aluminum jig. Steel resists corrosion much better than aluminum does, however, its weight and price prevent it from being a good material for the entire jig. A surface that’s steel-plated is corrosion-resistant and durable, so the value of the jig increases with this type of design.
How versatile a dowel jig is depends on a couple of factors; the number of connections it can create and its capacity. The top jigs offer a massive capacity of six inches or more. This will give the user the ability to do a wide range of projects. On the other side of the spectrum, smaller jigs allow you to work with smaller pieces of wood as thin as ¼-1/2 an inch. If you plan on working with wood that small, be sure the dowel jig you purchase is able to clamp down small enough.
You should also consider the types of connections the jig is able to make. The three most common connection types include:
- Edge to surface
- Edge to corner
- Edge to edge
Unfortunately, not every jig can support those types of connections.
One of the most underrated features in a jig is accuracy. The ability to self-center is only part of the equation. If the holes for the woodworker’s bushings have been drilled incorrectly, then this will be a major problem. The inability to insert the bushings will be a hassle, however, there’s a chance that the woodworker can drill them out larger, using a drill press. Regardless, that can be a pain and one that the woodworker shouldn’t have to deal with if they’re spending a good amount of money on a jig.
Additionally, if the bushings are too loose, then it can be difficult to get an accurate hole. Even a small gap can be a big problem, so it’s always smart to invest in a dowel jig that doesn’t have these types of issues. Another common problem is the holes for the bushings are loose enough, but they’re too tight for simple operation. The bushings can get stuck or the head can even break off, which leaves the woodworker with a ruined bushing and a ruined jig.
Dowel jigs will vary in features and price. These tools range from non-adjustable, simple $10 models, to $300 multi-adjustable jigs. Under $50 you can find a self-centering model that comes with removable drill guide bushings and can be used for most doweling jobs. You’ll also need a bullet-point or brad-point drill bit to match the jig bushings. You can easily find a dowel jig that will work for your budget, just be sure to invest in the right tool, one that comes with the features you need for your future woodworking projects.
The Right Dowel Jig
There’s no right model for everyone. You’ll need to look for a jig that meets all of your project needs. These needs tend to vary from person to person, so there’s no single model that will work for everyone. The best way you can get the most value out of your jig is to consider exactly what you’re going to be doing with your new jig, the common type of wood thicknesses you work with, the type of projects, and the type of connections. Once you’ve figured this out, then you’ll have a list of needs that can make it easier to choose a dowel jig that’s right for you and your future projects. After you’ve searched for models that meet your criteria, you can create a shortlist of models and purchase one that works with your budget. This way, you’ll get the capability you need from a new jig, at a price that’s reasonable.
Frequently Asked Questions
Are screws Stronger than Dowels?
Most woodworkers can agree that dowel joints are stronger than screw joints. The increased glued surface that’s caused by glue that deeply penetrates the wood will give a dowel more holding power. A screw can easily strip out this type of material, while a dowel will not strip when the joint is set in glue.
What are the Disadvantages of a Dowel Joint?
A dowel joint requires more time to create compared to mortise and tenon joints. It also involves the use of doweling, so for beginners, using this type of joint can be pretty complicated.
Which is Stronger Dowels or Pocket Holes?
Traditional joints tend to be much stronger than pocket holes. A dowel joint is actually 1.5 times stronger than a pocket hole joint.
Do Dowels Need Glue?
If a dowel fits their hole snugly, the way they should, then glue that’s placed on the dowels will end up being scraped outwards along the dowels when they’re inserted. Because of this, you should apply glue in the dowel holes only.
How Much Weight can a Dowel Hold?
Studies have shown that a one-inch dowel can handle three thousand to four thousand pounds.
Are Dowels Necessary?
Just clamping and gluing can result in parts that are aligned improperly. Additionally, using wood dowels will allow the joints to be fastened more securely, at the correct alignment. Dowels will keep the joints in the proper position, which can prevent misalignment in the future.
How do You Attach a Dowel to the Wall?
To do, you’ll begin by predrilling a hole in the center of each dowel. Use pliers to screw the dowel screws into holes. You can mount dowels directly into the wall studs using a level to make sure that they go in straight, or you can use appropriate anchors based on your type of wall and then mount some dowels.
Why are Dowels Often Used in Making an Edge Joint?
Using a dowel in a butt joint will increase the mechanical resistance to any lateral stresses and will help to maintain alignment when the boards are glued together. While this method is a popular alternative to a basic butt joint, it can often create a cross-grain assembly.
As you can see, these days, there’s no shortage of options when it comes to different types and styles of jigs but finding one that will work for you and your woodworking needs can still take some research on your part. The best dowel jig offers the right width, a sturdy frame, a self-centering feature, and the type of connections and size capabilities you need, so you can take on a wide range of projects you love.
