Self-Tapping Screws: How They Work and How to Use Them

Posted on by

When looking for fastening solutions, one common solution to use for routinely maintained products is self tap screws.

 

What Is A Self Tapping Screw?

 

Self tapping screws are fasteners that are designed to drill their own hole as they are screwed into wood, plastic or metal. By using a screw driver and self-tapping screws, precisely fitted threads are created. Self tap screws are ideal for items that require regular maintenance and work well when working with two different kinds of material being fastened together.

 

These screws either come with a blunt, flat, sharp or piercing tip. Sharp-tipped self tapping screws drill their own holes in softer wood and plastic. However, it is helpful to drill a pilot hole when working with harder material. When drilling a pilot hole, make sure to use a smaller bit than the screw so it may still serve its purpose.

 

What material is involved can help determine what type of self tap screw will work best. There are two types: thread-forming and thread-cutting. Thread-forming screws are usually used when working with plastics. Thread-forming screws are designed to stay in place tightly, but over tightening the screw could result in materials breaking under too much pressure. Thread-cutting screws are used mostly when working with metal and wood. One drawback to using thread-cutting screws is that the threads may strip if the application is disassembled. This prevents reuse of the fastener and requires a new, slightly larger self tapping screw when it is time to reassemble.

 

However, there is a solution to prevent stripping. A metal insert can be installed from the beginning that would allow the self tapping screw to be regularly fastened and unfastened. These metal inserts also work to help minimize stress and expand as the fastener is screwed in.

 

Just like other types of fasteners, self tapping screws are available in all shapes and sizes and are also available in numerous different head types. When choosing the right self-tapping screw for any given application, it is important to consider the length of the screw tip. In order for the screws to serve their purpose and work properly, the screw must be drilled fully into the material before threading can begin.

 

Although self tapping screws are typically more in terms of price, they can help cut down on time and labor costs and combine the steps of drilling and fastening.

3 Must Have Woodworking Machines for Every Workshop

Posted on by

If you are an aspiring woodworker, who wants to take up woodworking professionally you should give ample thoughts to buying essential woodworking machines that you will need to carry out woodworking projects efficiently. Just like any other craft, woodworking begins with mastering the basic skills and knowledge to use the fundamental tools efficiently. Of course, a lot depends on the kind of projects you want to take up. But make sure that you invest in the essential woodworking machinery gradually. This way you will be able to assess if you really need a particular machine or not. As you gain more experience in the field, you will be able to find more specialized tools that allows you to do more things efficiently.

 

In this article we will not discuss about the basic hand tools that you will need to get started in woodworking, rather we will concentrate on choosing the power woodworking tools, which will take your woodworking experience to a whole new level. The first three woodworking machinery, that we would recommend any aspiring woodworker are: a table saw, a portable planer and a plunge router. With these, you will be able to carry out a number of tasks, right from milling, joinery and shaping.

 

These Three Different Pieces Of Woodworking Machinery Are Very Important:

 

  1. The Table Saw:

 

A table saw is at the heart of every woodworking workshop. There are several reasons why it has that coveted place among the woodworking machinery you have in the workshop– it not only allows great precision in ripping a stock in straight lines but is also useful in cutting it at various angles. It does the basic milling of a stock with ease and is well suited for joinery works.

 

When choosing a table saw, there are a number of factors that you need to consider. The first thing you need to understand is that – it is going to be one of the most used machinery in your workshop, so you must always buy a quality one. The work surface of the table saw should be rigid and strong, and should be able to sail through all types of projects. Ideally, you should buy one that has a handle to raise and lower the blade easily, and another handle that will enable you to adjust the angle of the blade. Another essential feature that it must have is the connection for dust collector. It should have powerful motor that will let you cut through hard wood and make deep cuts. The blades of the table saw are incredibly sharp, so they should come with a blade guard and a power switch that is within easy reach while working on it. Many table saw today come with a paddle switch that can be pressed with your knee or foot if you need to shut it down in an emergency.

 

  1. The Surface Planer:

 

A surface planer is another indispensable woodworking machinery to have in a woodworking workshop. It can help you to be incredibly creative in the work you do by smoothing any rough saw stock to your desired thickness. Gone are the days when a stock was hand planed tirelessly to get the designed thickness and smoothness, a surface planer can help you get the same result in a short time. Typically, a planer has a table of the dimension between 10” to 14” on which you can feed your stock. There are a set of blades that rotates, thereby cutting the wood as it is fed through it. You can adjust the depth of the cut b using the crank at one end of the planer.

 

Another important feature that you should consider having in your surface planer is a dust vacuum. This machine generates a lot of dust, so having a dust collection system in place with lengthen its life. This machine is quite noisy when it is at work, so always wear hearing protection when you are using it. If not used with care, it can be dangerous too. So, adhering to the safety precautions is of prime importance.

 

  1. The Router:

 

Every professional woodworking will have a router in his workshop. It is one of those wondrous pieces of woodworking machinery that can carry out a number of tasks for you – not only trimming and decorative edge treatments but also various joints like mortises, rabbets, and dadoes. By having a router in your workshop, you are adding versatility in your woodwork. By making use of patterns, you can create identical parts from wood.

 

A router makes use of various bits to produce a number of shapes. For beginners, a stationary base router is good enough. It will help you make cuts at a depth you make before making a cut. For advanced woodworkers, a plunge router can add a creative touch to the work. The plunge router bites into the wood, makes the cut and then allows you to lift it back. When choosing a router, choose one that is at least 2 HP or it won’t be powerful enough to carry out various tasks for you. You should also choose one that comes with variable speed. Collet size is another feature to consider. It is important if you want to use various bit sizes. It is important to remember that smaller bit can be put into larger collet size but not vice versa. The power should be within the reach of your fingers, and you should not need to take your hands off the router to switch it on or off.

 

Other than these 3 woodworking machinery, there are a few other power tools that you can consider buying. One is a good jigsaw. It is a very useful tool that can help you in varied tasks like cutting curves. When buying one look out for one that comes with blade guides as it will help in keeping the deflection of the blades to a minimum. Apart from that a handheld drill and a quality random orbit sander with a provision for dust collection are great power tools to have in your arsenal. Quality of these tools should always be of prime importance when choosing these tools and one should always remember to adhere to the safety norms while using them.

How to Shut Off Your Home Gas Supply Valve

Posted on by

Shutting off utilities such as your home’s water supply or electrical power is fairly common—something you do whenever making a repair or upgrade. Shutting off your natural gas supply is not something that occurs very often, but there are still times you may need to shut off the gas supply in your home. Knowing how to do this is important, because when it’s necessary, it may need to be done in a hurry.

 

Reasons for Shutting Off the Gas

The main shutoff valve controlling you home’s natural gas supply may come into play during major construction or renovation involving gas lines, when closing up or shuttering a home, to prevent possible flood damage. Or, in rare instances, you may need to shut off the gas valve when a gas leak is suspected inside the home.

 

Once the valve is turned off, however, do not turn it back on by yourself. It must be turned on by a qualified person such as a gas company service technician or a licensed plumber. To be a “qualified person,” you must be able to confirm proper operation of all pilot lights and gas appliances once the gas valve is turned back on.

 

Location of the Main Shutoff Valve

The main gas shutoff valve is located next to the natural gas meter supplied by your utility company. Your gas meter may be located outside your home on an exterior wall, or it may be found inside your home on an outside wall—often in a basement or utility area, such as a garage or the mechanical room where the furnace or water heater are located.

 

How to Shut Off the Main Gas Valve

The main gas shut off valve is a large valve located next to the natural gas meter. If the valve handle is parallel to the gas pipe, then the gas supply valve is open and the gas is on.

 

  1. To close the valve, use a clamping plier, an adjustable wrench, or an open-end wrench, and turn the valve handle 90 degrees so it is fully perpendicular to the gas line. It is a good idea to keep a wrench handy for this purpose and keep it located next to the shutoff valve.

 

NOTE: Many natural gas meter valves provided by a utility company have a hole in the handle that will line up with a corresponding hole in the valve body when the gas valve is in the closed position. The utility company will use the hole to lock and/ or seal the valve in a closed position when the gas account is closed. When the holes in the valve handle are lined up, it indicates the valve is in the OFF position.

 

  1. To ensure sure the gas shutoff valve is, in fact, fully closed, note the dial numbers on the meter face and write them down. Then check back in about 10 minutes. If the numbers have not changed, then you know that the shutoff valve is fully closed.
