What to look for While Buying Parallel Clamps

Before you get shopping for a couple of parallel clamps, there are some factors you must keep in mind to choose the best woodworking clamps. Here, we’re going to show all of them. Take a look:

Clamp Materials

Most clamps are made of aluminum. This includes the bar and the clamping jaws. However, there are other materials like plastic and steel you may also find useful.

Plastic, for example, makes the clamps lighter. This is an excellent idea if you want maximum precision and ease of use. Steel models are made to last, while they can be a bit heavier, using them requires way less effort than usual.

Clamping Pressure

You'd be surprised by how common incorrect clamping pressure is. If your parallel clamps can barely apply any strength when you're trying to fit two boards together, the end result will be a poorly glued board.

So, when looking for a parallel clamp, we suggest going for those that can apply at least 880 pounds of clamping pressure. Of course, you can go above that number depending on what you need.

Padded Jaw

Parallel clamps can offer both convenience and accuracy. However, here is the catch: if they don't have a padded jaw, you're not going to have much fun doing glue-ups.

A padded jaw acts as a special shield that protects the wood from getting damaged as you're tightening the clamps.

Anti-Slip Jaw

When you set your clamp to the position needed, some of them might move as you turn the parallel clamps, which is rather inconvenient.

The best way to ensure your jaws will remain in place even if you give it a shake is by making sure your parallel clamps have an anti-slip mechanism.

Otherwise, you'll have a hard time trying to set the clamps to the desired location without them constantly moving along the rail.

Ergonomic Handle

Ever felt as though your clamps feel pretty uncomfortable to hold, and it never got any better? Well, they probably don't have a comfortable handle.

Getting a parallel clamp that actually has a comfortable handle is crucial if you don't want to hurt your hands as you're working.

Spreader Capacity

We want to stretch out how important it is to have a parallel clamp that also works as a spreader. While most parallel clamps can be used as a spreader, there are many of them that, unfortunately, do not offer much customization.

While you might not need the spreader right now, it always comes in handy to have that extra feature when you're dealing with wood.

How to Use A Parallel Clamp?

Are you a beginner who has no clue whatsoever on how parallel clamps work? If that's the case, well, then this guide will serve as a great starting point. Here, we'll cover how you can use those seemingly hard clamps you recently bought.

Adjust The Rail

The rail is where you place your wood. They have supports on top of them, which are often referred to as feet. Those blocks allow you to slightly lift up the boards you're trying to put together.

Some parallel clamps have a measuring system, which, as the name suggests, allows the user to measure their boards without any extra tools. So, to use parallel clamps, you must first place them next to each other.

You should keep in mind that you must leave some space for the wood to fit in. Also, before applying the glue, we suggest leaving some space for the boards.

Hold the Wood

The jaws will hold the boards together to ensure the glue you're about to apply does its job. However, before you glue the boards, you must make sure they're perfectly aligned with each other. Otherwise, you'll end up with an uneven result.

So, you have to glue the boards and then place them next to each other on the rail. Once you've perfectly positioned them, you're ready to move onto the next stage of this simple job.

Tighten The Jaws

Now you just need to turn the handle of your parallel clamps. With firm pressure, you're guaranteed to get a permanent bond for the boards. Follow these steps to ensure you apply the right amount of pressure:

  • First and foremost, you want to turn the handles to apply pressure.
  • After that, take two clamps and place them on the edge of your board. By placing an extra clamp on the edge of your board, you'll be able to level up the limber.
  • All the pressure that's being applied from the clamps should produce an even glue line in no time.

And that's it for the parallel clamps. You've successfully learned how to use your new set of parallel clamps.

Frequently Asked Questions (FAQs)

In this section, you'll find five useful questions about parallel clamps. Here are those five questions:

Yes, parallel clamps are worth every single cent if you're doing glue-ups. Joining two boards is super hard without them. You don't need that many, at least for now. As time goes by, you'll end up buying more of them.

Do I need parallel clamps?

Yes, you do need them. Doing glue-ups requires precision, and parallel clamps can do that without much effort. Furthermore, they are essential tools for any aspiring woodworker that is serious about making money off of it.
