A biscuit joiner is an excellent way to connect different carpentry elements of woods together – fast and efficiently.
Interestingly, this machine can create a perfect seamless joint for your woodworking projects in the nick of time.
This tool helps with time-efficient and accurate wood joining compared to other woodworking methods.
What is a biscuit joiner primarily used for?
- Biscuit joiners combine wood to form a solid and sturdy connection for woodworking projects.
- As the biscuit prevents any lateral movements this method secures wooden elements more firmly in place than glue alone.
Types of joints you will be able to do!
These are the uses of a biscuit joiner when the time arrives for woodworking in the garage or workshop:
1. Glue wood edges together
Given the solid binding potential, using a biscuit joiner is an excellent way for connecting timber edge-to-edge joins. Having a biscuit sandwiched between two boards of wood prevents any lateral movements.
In addition, a biscuit joiner allows you to make fast and seamless connections with your edge-to-edge joints in carpentry and woodworking.
Making edge-to-edge joints is incredibly easy if you use a biscuit joiner.
2. Hold miter joints tight
Tightening up your perfectly cut miter joints is one of the best uses for a biscuit joiner.
Like we said earlier, a biscuit joiner allows you to create seamless connections in wooden joints. The same applies when doing miter joints.
The biscuit acts as a bridge, a joiner, and a fastener when used in a butt-join or a miter joint.
We find the tool effectively connects two pieces of wood for a miter join while securely pulling and holding pieces together until the glue dries by using high-quality quick release clamps.
3. Butt joins for wooden parts of furniture
Another joint that a biscuit joiner can do is the butt corner joint. You can see corner joints more commonly in wooden furniture.
To form shapes similar to the letter L when done correctly. Butt joints are easier to achieve, using a biscuit joiner that allows you to do corner joints in your projects without any downtime.
4. Align wood pieces.
Using a biscuit joiner allows you to align general wooden pieces with ease. This enables you to also do face joints with minimal difficulty.
The biscuit joiner gauge can help you mark where to engrave your hole in the joining position. In addition, a biscuit joiner secures your wooden parts together so that they do not move or misalign later.
How does a biscuit joiner work?
A biscuit joiner works by doing the following:
- First, the slot is cut out and created by the tool that serves as a fitting for a biscuit-shaped piece of wood to be inserted into. The biscuit size depends on the size of the slot you cut and the size or the depth adjustment of the blade installed.
- Second, once you place the biscuit and connect the two edges, the support acts as a binder for the two wood components to stop lateral movement.
- Third, when you apply wood glue to the biscuit and inside the join the biscuits will expand with the glue and hold the two pieces together even more firmly. You should temporarily secure the different components and pieces with wood clamps until the glue dries.
Tips
If an excess amount of glue leaks in front of the joint when getting clamped, you should remove the run with a scrapper or with a rag.
If the biscuit is too wide for a narrow gluing job you can reduce the depth of the tool and trim the biscuits with a dovetail saw.
When to use a biscuit joiner?
You can use a biscuit joiner to join almost anything wood that is made to be used indoors. However, there are areas in wood craftsmanship where a biscuit joiner shines the most.
Take a look at these biscuit joiners’ uses:
1. Creating timber frames
One of the common uses of biscuit joiners is connecting timber frames together.
A biscuit joiner is an excellent tool when doing edge-to-edge and miter joints.
As such, a biscuit joiner is an impressive tool for building wooden frames. These wooden frames include those used for printing, packaging, storage, picture frames, mirrors, etc.
2. Doing Indoor carpentry furniture projects
Given the versatility of a quality biscuit joiner, you can expect the tool to help you accomplish secure joining for your indoor furniture projects.
The biscuits can fail exposed over time if exposed to moisture. But for indoor projects or if the join is sealed to not let any moisture enter you can use one for sheltered outdoor projects with low humidity. Otherwise use dowels, shiplap joints, or screws.
3. Creating seamless connections
A biscuit joiner is known for creating seamless connections. The biscuit joiner fastens the wood together by creating tension in the build, creating a seamless connection.
When not to use a biscuit joiner?
If you are building a project that needs to support a strenuous and heavy workload on a building project, a biscuit joiner is not adequate for structural joints in construction.
For outdoor furniture, a biscuit joint does not penetrate the wood deeply compared to a long dowel, or mortise.
The material of the biscuit unfortunately will not hold up against exposure to any water or moisture.
Common projects to use a biscuit joiner
1. For tabletops
Most households prefer a clean look with their tabletops.
And many woodworkers use a biscuit joiner to create larger tabletops by using the tool to connect large pieces of wood together as a way to create seamless connections to wooden surfaces [1].
DIYers use biscuit joiners to bind boards and tabletops without needing heavy machinery.
You can mill your own lumber first by using a portable Alaskan chainsaw mill.
2. For making cabinets and drawers
Like we said earlier, a biscuit joiner is an excellent tool to have when making edge-to-edge and miter joints.
These types of joints are commonly used when making cabinets and drawers.
The seamless connection a biscuit joiner creates makes building both the cabinet and drawers for a project a whole lot easier.
Resulting in us having such popularity for the tool.
3. Making wooden boxes
Binding various boards together is no issue when using a biscuit joiner.
Given the multiple joints a biscuit joiner can do in only a few minutes, you can create wooden boxes according to the look [2], size, and function you want.
Furthermore, you can use double, or triple biscuits to ensure the strength you need for bigger boxes.
4. Face-joining wood
Another advantage of a biscuit joiner is that you can do face joints excellently.
As such, most edge band projects are connected using a biscuit joiner in the middle.
By using a biscuit, people can fuse different boards together to help hold the center together without issues of popping.
Plus, this does not require you to operate heavy machinery. The tool is relatively lightweight and easy to use.
What are alternative timber joining methods?
Dowel joints
A dowel joint as mentioned previously is considered one of the most robust methods of timber joining. A dowel joint is made using a drill and flush cutter.
Essentially, a dowel joint works similarly to a biscuit joiner. You use an item to create tension between two wood blocks that binds them together.
The difference between the two joints is that a dowel joint is shaped like a rod and can go deeper into the wood than a biscuit joiner.
This can be a more robust alternative to a biscuit joiner when you need greater strength from horizontal load or vertical pressure.
Mortise and tenon joints
Mortise and tenon joints work similarly to a biscuit joiner. Tension gets created between the two boards of wood which binds them together.
The difference between the two joints is that a mortise and tenon joint does not require another piece aside from the two pieces of wood.
One is engraved with a hole, while the other is given a protrusion that fits perfectly in the spot. This type of joint is commonly used in projects that need to support strenuous workloads like chairs and roof foundations.
However this takes time to make, and if not visual, you can waste time with this method.
What makes a biscuit joiner more time-efficient and accurate?
A biscuit joiner can be the essential tool to add or give to a woodworker’s toolbox that doesn’t yet have one.
As a tool with an accessible means of joining two or more wood pieces together.
With only a biscuit joiner machine, a biscuit, and glue to fuse two boards together, this is an easy solution for many woodworkers that we know and have debated on how often the tool is used.
Given the simplicity provided, you can do more wood-crafting projects without as much time compared to hand carving wooden joins with less accurate cutting.
I recommend that you do a test fit to ensure that the biscuit corresponds to the hole you’ve made before gluing.
Conclusion
In conclusion, a biscuit joiner is necessary when doing DIY garage woodcraft with the kids or crafting innovative woodcraft projects for your shop.
It is attainable and simple. Now that you know the biscuit joiner’s common uses, you do not need any other heavy machinery, or other pieces of equipment just to finish the task of joining wood.
I like how a biscuit joiner can be used in many different manners to join wood according to the demand of any woodworking job.
