How To Choose The Right Bar Clamps
Bar Clamps are used to securely attach a thin piece of materials in your work to any surface, typically flat. It provides you the leverage to safely clamp two pieces of wooden material together for bonding and molding purposes. This is an essential tool for woodworking as it has many advantages over the other common joinery tools such as a table saw. However, the strength of these clamps is sometimes questionable if not appropriate for the type of joint you intend to use. Thus, before purchasing one, it is important to take note of the following factors to consider before buying a bar clamp:
First, you should ensure the clamp is designed for the type of joint you plan to use. For instance, if you want to join two hardwood pieces together, the force required will be different. Bar clamps rated for heavy-duty usage can withstand tremendous pressure, while the force could be lower for lighter work. Hence, you should evaluate the required pressure rating for each specific type of joint before choosing the clamp.
Second, ensure that the clamp you select has the right opening capacity. Bar clamps have different opening capacities based on the joint being joined. For example, a high-quality f clamp with high tensile strength can open heavier and thicker pieces of wood than a standard f clamp with lower tensile strength. Thus, you need to assess the type of work you will be doing to determine the opening capacity. Most f-clamps have an eight-inch opening capacity.
Third, you should determine the weight of each of the pieces being joined to determine the maximum load rating of each bar clamp. The load rating is usually indicated on the side of the bar clamps. If the load rating is in ounces, the higher number indicates the greater weight the machine can withstand before it becomes unable to hold the piece together. Thus, you should consider these factors; the weight of each piece, the distance between the two points where the joint is joined, and the distance from the mechanism itself.
Fourth, you should also consider the mechanism being used. There are different types of bar clamps, such as bolt-on, turn-on, magnetic, and drop-in bar locks. Each of these mechanisms requires different types of tools for installation and operation. You can determine the appropriate mechanism suitable for your operation by considering the type of your business. This means that if you are looking for furniture in your garage, you will not use the same mechanism for a wall fixture you are trying to lock.
Fifth, you need to consider the recommended post spacing. Post spacing refers to the distance, which is recommended between the top woodworking clamps' bars. The recommended post spacing is based on the weight of each piece that you will clamp. Thus, if you are using bolt-on bar clamps, the recommended post spacing is 4 inches. However, if you are using magnetic clamps, the recommended post spacing is 9 inches.
Sixth, you should know that woodturning tasks require certain woodturning tools that are hard to find. Therefore, you should purchase your woodturning tools from trusted manufacturers. Some examples are jigsaw, router, sander, and the like. Also, you must learn how the different woodturning tools work so you will know how to use them properly.
Seventh, you can also purchase woodworking related instructional books and magazines. Some magazines contain step-by-step instructions on building woodworking machines such as lathes, carves, router bits, etc. There are also websites offering similar information about woodworking tools, pipe clamps, and woodturning supplies. In addition, some of these sites offer discounts on products so you can save some money. If you are interested in trying one of these out, contact your local tool shop or your favorite woodworking website.
