Parallelogram jointers are different from the dovetail jointers that we see. Don’t know what is a dovetail jointer? It’s just the regular jointer.

Now, what is a parallelogram wood jointer? 

These are average size power saws that are used to flatten the edges or the face of lumber. Parallelogram jointers are typically costlier than normal jointers.

You may be wondering what is the advantage of a parallelogram jointer. Is the extra money really worth it? 

Yes, it’s worth it because it needs less adjustment and it’s more convenient.

Whereas a normal jointer needs consistent and periodic adjustments to be made. But the parallelogram jointer doesn’t need that.

Nevertheless, no matter which jointer you’re choosing, you’ll need good quality blades. Because if your blades don’t last long then the jointer is ultimately useless.

With time your blades might become dull. Don’t forget to sharpen them using a whetstone. They’ll be sleek as mirrors again.

Now let’s check out the attributes that make the parallelogram jointer different from a traditional jointer.

The purpose of using a parallelogram jointer is the same as using a traditional jointer. Both are used to do quick work of flattening stock. 

So how does a parallelogram jointer work and what is the difference? 

Comparing parallelogram jointer vs standard jointer, we can find differences in a few aspects. Like, size, shape, price, etc. The jointer parallelogram design is also quite different from the standard one.

Let’s look at the differences in detail now.


Parallelogram jointers’ bases are often heavier than standard jointers’ bases. It’s also longer than the standard jointers that offer better functionality.

To support the heavy base you’ll need a jointer table or stand.

However, as the stands have wheels, be careful while moving them on a slippery floor. You may need to check out some table adjustment parallelogram guides to operate it properly.


The rhomboid base of a standard jointer represents the pattern of a dove’s tail. They’re also called angled dovetail jointers or just dovetail jointers. 

They assist woodworkers to produce accurate wood products quickly if used with a dovetail machine.

On the contrary, the base of the parallelogram jointer has a shape like a parallelogram.


A parallelogram jointer is quite expensive in comparison to standard jointers. It costs 20-25% more than a traditional jointer. 

But additionally, if you need hand tools then consider getting some Dewalt hand tools.

Whether a parallelogram jointer will be worth it for you depends on what you’re intending to do. Most of the time, a parallelogram jointer is used for heavy-duty or professional work.

There are two options of six and eight inches of jointers. So you may choose according to your needs. You may need an 8 parallelogram jointer if you’re intending to do furniture work.

You may choose one between Jet or Powermatic jointers. Both of them are built for even heavier usage.

However, here are a few factors that you should keep in mind while deciding.

  1. A traditional jointer costs way less than a parallelogram jointer which makes them attractive. If you’re inexperienced and starting with lumbering, you may consider buying a traditional jointer.
  1. Don’t you intend to have heavy use for your jointer? Then a traditional jointer is enough. 

If you’re a beginner and occasionally use the jointer then a parallelogram will be overkill. But if you’re intending to heavily use the jointer then a traditional jointer can cause problems.

  1. If you make adjustments every now and then to traditional jointers you may wear it down. In turn, this will affect the performance of the machine.

Now let’s see a few jointer basics that might help you to operate it easily.

Few Jointer Basics

This segment is about the basics of different jointers. Dive and learn some additional information. So that if you’re getting a parallelogram jointer you wouldn’t have any confusion.

  1. Both the traditional and the parallelogram jointers have a rotating cutter head in the middle. When the lumber passes from one table to another it gets sliced by the blade. 
  1. The infeed jointer table is typically always adjustable in all types of jointers. In some cases, the outfeed table might also be adjustable.
  1. The tables must be adjusted and kept in a parallel alignment to work smoothly. Otherwise, the stock will not move smoothly through the tables and it’ll cause a jointer snipe. It’s very crucial to have smooth and square edges.
  1. The tables of a typical jointer glide up and down a horizontal bar. They glide up getting closer to the headstock as they are lifted. 

Wear and tear on both sections can be caused by the table moving along the inclined metal bar. It might be difficult to fine-tune a conventional jointer after this happens.

The adjustable components of a parallelogram machine are moved by a hinge or eccentric. And they do not wear out in the same way. 

You must fine-tune the settings of your parallelogram jointer while not causing any misalignment.

  1. Parallelogram jointers don’t need to be readjusted if used to maintain the given instructions. You can use it right after getting it out of the box.

On the contrary, a standard jointer needs adjustments after getting out of the box. The adjustments need to be made with the help of a set of gib screws. A heavy-duty shim can also be used if needed to make up for the twist. 

The gib screws need to be tightened and loosened. A specific sequence of turning the screws needs to be maintained. This needs a process of trial and error which may take quite a lot of time.

We hope the above info on different jointers will come in help. Now, let’s move on to the next part

Now let’s move on to the FAQ segment of the article.


Which one should I choose between 6 in and 8 in jointers?

Which one you should choose depends on your usage. But as a long-term investment 8 inches is always better. If you’re working with 6 inches of lumber, then 6 inches is enough.

What is the core advantage of a parallelogram jointer?

The core advantage of a parallelogram jointer over a regular jointer is simplicity. And with that, you may control the table height. The parallelogram’s camshaft and arc design allow the user to easily move up and down the table. 

How to square a board with a parallelogram jointer?

First, adjust the height of the outfeed blade according to your need. Then adjust the infeed blade. Next, flatten one side of the wood with the jointer. Now square the adjoining edge.


That will be a wrap for our article on what is a parallelogram jointer. Hopefully, now you know everything about parallelogram jointer and if you need it.

Using jointers can be risky so be aware of your safety.

Good luck lumbering and see you in the next one.
