Best Jointers: Jet & Powermatic
Jet joiners are popular among hobbyists because they are easy to use and have low maintenance requirements. They offer good performance at reasonable cost. However, they do not provide the same level of precision as other types of joinery. For example, it is possible to make a mistake when cutting through wood with a jet joiner. Also, the material used for making jet joins may not be suitable for some applications.
Powermatic joiners are similar to jet joiners but their materials are stronger than standard steel or aluminum. They offer excellent performance and are very reliable. However, they require special tools which may be expensive. The main advantage of powermatic joiners is that they work well even if there is no glue between pieces of wood (gluing).
In this article we will tell you about the advantages of each type of joiner.
Jet Jointers: Low Maintenance, Easy To Use And Affordable
The most common type of joiner is the jet joiner. These machines cut through wood using compressed air. A jet cutter uses a piston driven cylinder to cut through wood with high speed. The movement of the piston rod is controlled by an automatic mechanism. The automatic feed mechanism has many advantages over manual feed systems.
We found out that most people who prefer to use a jet joiner are doing it because of the lower price of the machine or the fact that you do not need to use glue when using this machine. It is true that a jet joiner works well without glue, but it does not mean that it is not necessary in some cases.
The high pressure air flow that is used for cutting can cause a lot of vibration when working with wood. Also, some of the parts of the machine are not waterproof, so you should keep them dry. Another disadvantage of this machine is the fact that it is large and heavy, so it is not very portable.
Advantage: Affordable, Easy To Use, No Glue Is Required Between Each Piece Of Wood
Disadvantage: Large And Heavy, High Vibration While In Use, Not Waterproof
Powermatic Jointers: More Precise And Stronger Joints
The most important advantage of a powermatic joiner is that it gives stronger joints than jet joiners. This type of machine provides high quality cuts and works very accurately. It uses compressed air to cut through wood like the jet joiner does, but it also has some unique features.
This machine has an automatic material thickness compensator which provides more precise cuts. It uses high-speed steel cutting blades instead of the softer steel used by the jet joiners. Also, powermatic jointers offer higher duty cycle than a jet joiner or any other type of woodworking machine. This means they can run longer before they overheat. If you are planning to use this machine for extended periods of time, then this is a very important feature.
Another main advantage of a powermatic joiner is that its parts are not directly exposed to air flow and dust. This feature makes them more durable. You should also know that all the parts of a powermatic joiner are sealed, so it is fully waterproof.
A disadvantage of this machine is that it is quite expensive. Its price is nearly twice as much as a jet joiner or other similar woodworking machines.
Advantage: More Precise, Stronger Joints, Longer Duty Cycle, Durable
Disadvantage: Very expensive
If your main goal is to save money then we would recommend that you buy a jet joiner. These machines are affordable and more than good enough for most people. If you want something more professional then you should get a powermatic joiner. This machine is more expensive and it offers features that you will find very useful.
