Parallel clamps can prove to be a hassle. At times the heads break or the clamps don’t clamp tight enough. In addition, sometimes they bend out of form, or just plain do not clamp tightly enough. And so, is there any chance for parallel clamps to save your project? Let’s look at the situation.
The main problem with parallel clamps is that often we buy them without thinking. We simply look at the price and choose the cheapest one available. The problem with that is we then make our project difficult because we are unable to tighten the screws or bolts securely. If you need tightness in the screws or bolts, you simply cannot buy parallel clamps that have adjustable shoulders. Some will offer a removable shoulder for much cheaper, but you must remember that the free handle is only adjustable up to a few millimeters, which is far less than most handymen will have to work with.
The next main problem with parallel clamps is that they are usually made from materials that are cheap and easily break. Some have been known to last for only a few months, while others have been known to last for years! But, on the upside, they usually only cost a few dollars per set, whereas the specialized and slightly more expensive Stainless Steel Clamps may cost thousands of dollars per set. So, if you only buy a few sets, you will probably use them out right, whereas the specialized and more expensive ones will probably not use until they break.
Another problem with them is that the design of the jaw is flawed. Most parallel clamps have a flat plate inside of a circle. This plate, when tightened, causes the jaws to close on each other. However, this is not how they are supposed to work. It causes them to move out of alignment, which causes them to be loose and eventually break.
If you have used non-parallel clamps before, then you know how easy they are to remove. They slip right out of alignment. This means that if you need to make sure they stay where you put them, that you really have to watch them closely. This is why you have to be careful when tightening them. You can over tighten them, causing them to slip out of alignment, and cause them to become useless. Watch them carefully so that you don’t make a mistake like that.
When you buy new parallel clamps, make sure to check the teeth closely to make sure that they are square. If not, then it will be very difficult for you to tighten them properly. The more teeth that are aligned, the better the clamping action will work. The more even the teeth are, the easier the clamping action will be.
To make sure that you are using the best parallel clamps, you should also pay attention to the teeth themselves. In order for the jaws to work well, they must be made of the right material. If they are plastic, then chances are they are not going to glide as smoothly across your workpieces. Plastic won’t work as well in confined areas such as in the recesses of large workpieces. This is where they will most likely break.
Another tip for buying parallel clamps that works best with heavy-duty clamps is to look for the type that features an adjustable jaw. These clamps that are designed to work with either one, two, or even three long jaws. When a continuous motion is required with your glue-up, it will be easier for you to do it.
One of the main problems with using plastic parallel clamps is that the individual jaws tend to pull apart rather easily. They can separate so much that you may not be able to get a steady hold on the piece. This means your workpiece can move around and you’ll have a hard time holding it down. On a piece of furniture, this can mean the end of its life.
Another important tip when purchasing long-lasting glue-ups is to find ones that feature ergonomic designs. There are jet parallel clamps that feature ball bearings. This feature will ensure that they work properly and won’t be prone to breaking. The ball bearings can run on either long or short lengths. If the product features both types of lengths check price ranges to see which one is the best deal.
Versatility is another factor that makes these type of clamps a good choice. Jet parallel clamps that feature a ball bearing have different ball bearings on each side. This will allow you to choose the length that best meets your needs. You can also get different jaw styles depending upon the application. The jaw can either close on a smaller or larger area, depending upon how much surface area of the clamping pad can cover.
Durability is yet another reason why many clamps are made with steel. Steel makes up the frame of the unit and plastic surrounds the metal. Steel is extremely durable and holds up under many conditions. Plastic, however, can easily break if the unit is subjected to very heavy use or is left outside for long periods of time. Because of this, many clamps now feature aluminum construction for added durability.
The best parallel clamps use ball bearing jaws. This is because the ball bearings make the jaws rigid. With this feature, the unit is more durable and will stand up over many applications. Because the jaws are rigid, you can also tighten them with an easy pull or press method without having to remove the fixture.
In addition to being able to purchase the best parallel jaw clamps, you can also find many other types that feature their own set of features. Powertec clamps are one example of this. These power tools feature an elongated commutator bar that features diamond shapes cut in its center. This diamond-shaped bar makes it possible to tighten and loosen the bolt in multiple ways. There are many other powered clamps available to purchase online as well, making it easier than ever to find the perfect product for your needs.
