What is F clamp

An F-clamp, also known as a bar clamp or speed clamp and a "G-clamp", is a type of clamp. The name comes from its "F" shape. The F-clamp is similar to a C-clamp in use, but has a wider opening capacity (throat). This tool is used in woodworking while more permanent attachment is being made with screws or glue, or in metalworking to hold pieces together for welding or bolting.

An F-clamp consists of two horizontal bars joined together by a vertical bar. There is a large screw on the lower bar to allow for the clamp to be tightened. F-clamps are adjustable which allows for them to be used on larger scale objects without the need for a large screw.

An F-clamp is also a simple mechanical device used for lifting engine or transmission parts. The clamp has an adjusting screw to tighten onto the part and a lifting ring to attach a hoist cable.

F-clamps in the industry terminology have the jaws mounted on a flat bar, while a pipe clamp, which has the same construction, is mounted on a pipe, normally of 1/2" or 3/4" diameter.

How to Revive a Bonsai Tree

Is your Bonsai tree starting to look a little bit tired? Perhaps you received your Bonsai as a gift or maybe you bought it from a garden centre? The point is, unless you correctly look after your miniature tree then things can go wrong, and all too quickly!

If your Bonsai tree is starting to look past it's best there are certain things you can do to give it a new lease of life.

It's a good idea to think about re-potting your Bonsai tree every couple of years or so, and early spring is an ideal time to do this. You will need some good quality potting compost with a mix of grit or sand to help drainage.

Also consider trimming the roots if your Bonsai tree looks really confined and compacted down there. The roots maybe getting too big for the pot, so a quick root haircut can often work wonders. You will obviously need to remove the old soil first to expose the roots. An ideal tool to help you do this is a humble ice-lolly stick.

Like any tree a Bonsai tree is most suited to its natural habitat, and therefore should be outdoors. If your Bonsai tree is located somewhere inside your house, try moving it outside for a while and see if it recovers.

Don't be afraid to move your Bonsai tree outside during the winter months either. Most trees are dormant at this time and well adjusted to the cold. Just make sure that you pick a well sheltered spot, and ensure that the compost doesn't freeze.

When it comes to watering your Bonsai tree you need to keep the soil moist all of the time. Never let your tree dry out and never let it get waterlogged. Trapped water will likely rot the root system and kill your Bonsai tree quicker than anything else. Therefore you need to make sure your Bonsai pot or container has enough holes to allow adequate drainage.

Bonsai trees need pruning, so if yours is getting too big, simply cutting the top off will stop it getting any taller. Just make sure you use a sharp pair of scissors or secateurs as you don't want to cause any infection. Also, this will cause your Bonsai tree to grow new branches and therefore will appear wider and fuller. When pruning branches, always cut back to a bud, any new branch will then follow that route.

What is G clamp

A C-clamp or G-clamp is a type of clamp device typically used to hold a wood or metal workpiece, and often used in, but are not limited to, carpentry and welding. These clamps are called "C" clamps because of their C shaped frame, but are otherwise often called G-clamps or G-cramps because including the screw part they are shaped like an uppercase letter G.

C-clamps or G-clamps are typically made of steel or cast iron, though smaller clamps may be made of pot metal. At the top of the "C" is usually a small flat edge. At the bottom is a threaded hole through which a large threaded screw protrudes. One end of this screw contains a flat edge of similar size to the one at the top of the frame, and the other end usually a small metal bar, perpendicular to the screw itself, which is used to gain leverage when tightening the clamp. When the clamp is completely closed, the flat end of the screw is in contact with the flat end on the frame.When the clamp is actually used, it is very rare that this occurs. Generally some other object or objects will be contained between the top and bottom flat edges.

Light Duty G Clamp

A G-clamp is used by means of turning the screw through the bottom of the frame until the desired state of pressure or release is reached. In the case that the clamp is being tightened, this is when the objects being secured are satisfactorily secured between the flat end of the screw and the flat end of the frame. If the clamp is being loosened, this is when a sufficient amount of force is released to allow the secured objects to be moved.

While a G-clamp is a useful tool for woodworking, special care should be taken when working with delicate woods. The flat gripping edges of the frame, generally no larger than half an inch or a centimetre (depending on the size of the clamp) can cause indentations and marring of the surfaces being clamped. This can be avoided by buffering between the clamp and the timber using two pieces of scrap wood. As each piece of scrap wood is directly in contact with the flat edges of the frame and with the items being clamped, this allows the scrap wood to receive the damage from the clamping, while dispersing the clamping force across the piece of scrap wood into the clamped objects. Deep-throated clamps are also available and provide greater reach for smaller jobs.

What is screwdriver and the features of phillips screwdriver

A screwdriver is a tool, manual or powered, for turning (driving or removing) screws. A typical simple screwdriver has a handle and a shaft, and a tip that the user inserts into the screw head to turn it. The shaft is usually made of tough steel to resist bending or twisting. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw—or ridged or treated for additional 'grip'. Handle are typically wood, metal, or plastic and usually hexagonal, square, or oval in cross-section to improve grip and prevent the tool from rolling when set down. Some manual screwdrivers have interchangeable tips that fit into a socket on the end of the shaft and are held in mechanically or magnetically. These often have a hollow handle that contains various types and sizes of tips, and a reversible ratchet action that allows multiple full turns without repositioning the tip or the user's hand.

Phillips screwdriver

A screwdriver is classified by its tip, which is shaped to fit the driving surfaces—slots, grooves, recesses, etc.—on the corresponding screw head. Proper use requires that the screwdriver's tip engage the head of a screw of the same size and type designation as the screwdriver tip. Screwdriver tips are available in a wide variety of types and sizes (List of screw drives). The two most common are the simple 'blade'-type for slotted screws, and Phillips.

Phillips screwdriver

A wide variety of power screwdrivers range from a simple 'stick'-type with batteries, a motor, and a tip holder all inline, to powerful "pistol" type VSR (variable-speed reversible) Cordless drills that also function as screwdrivers. This is particularly useful as drilling a pilot hole before driving a screw is a common operation. Special combination drill-driver bits and adapters let an operator rapidly alternate between the two. Variations include impact drivers, which provide two types of 'hammering' force for improved performance in certain situations, and "right-angle" drivers for use in tight spaces. Many options and enhancements, such as built-in bubble levels, high/low gear selection, magnetic screw holders, adjustable-torque clutches, keyless chucks, 'gyroscopic' control, etc., are available.

Solution for woodworking

Woodworking projects are a mixed bag. It can be fun and frustrating at the same time. The greatest anticipation and driving force is the anticipation of the finished product. There is something gratifying in having that almost finished project in front of you ready for the finishing touches. It has been a great project, everything turned out perfect now comes the final decision which is how do you finish it off? One of the most appropriate materials for doing projects yourself is wood. It's affordable, relatively easy to use, and friendly to the environment and long lasting. If you are an enthusiast or even just a beginner, here are seven great ideas for woodworking projects that you can do yourself and be proud of the result.

Woodworking is a marvelous pursuit that calls for both skills and creativity. Although many have a desire to create their own sculptures, utilizing woodworking patterns gives you a decisive advantage. This is due to the fact that you not only will have a plan and know what you are trying to do, but you will also have step by step directions that guide you along the way. The 1st tip to fine-looking woodworking is to pick out a plan that matches to the project you are designing.

An eye-catching project is something that is worthy and a valuable addition to your home or even a marvelous gift for family or friends. Designs and plans from other countries or for particular cultural designs are usually catchy and fun to make. In order to find such exotic woodworking patterns you should go online and do a search. There will likely be many sites offering plans and patterns so take a time to look through them and get some thoughts for your project. Woodworking is an exceptional hobby or even a profession. No matter what your skill level is, you should observe the tips and work with patterns and plans to ensure that your project is successfully accomplished. Woodworking patterns also make it easy to know what to do and in what order, which means you will savour finishing the project and in the end have something sacred that you will cherish for many years to come.

Project Planning is Important:

Like everything else, woodworking works best when you have an initial plan. Aside from finding out what you want to make, you should also have specific blue prints to follow. Pick projects that are at the level of your own personal expertise. You shouldn't hope to work and finish a project that is clearly out of your league. Beginners would do well to practice their skills on basic block projects. Examples of these are keepsake boxes, shelves and wood puzzles. Once you have mastered making these basic objects, you can go on with more demanding projects.

Know Your Wood and Tools:

Woodworking is not as easy as working on a piece of wood with a hammer and chisel. You need to learn a couple of important details about wood. You should know for example that there are so many choices of wood for projects. Not all of them will be ideal for your projects. Different kinds of wood have different grains, appearances, interactions with finishes and reactions to environmental exposure. The ease of molding, shaping and handling wood will also depend on the type of wood.

Planning simple wood working projects also means that you need to find out about wood tools too. This can be as confusing as identifying various wood types. There are numerous wood tools to consider and each type may have various kinds. There is a huge difference between hand tools and power tools. You may have to begin learning to handle hand tools first before moving on to power tools.

5 Tools Needed When Building or Working on Your Computer

Hello fellow computer builders. I'd like to send a special welcome to all newcomers. I am under the impression that we are all here, because we are ready to start building our computers from scratch. If that's correct, then let's get started.

If you've read my other articles, you've come to realize that you first need a plan. This is essential for any venture you set out to do, if you plan on doing it as efficiently as possible. In building computers, you need a plan if you intend on getting compatible parts at a competitive price.

You've developed a plan and purchased the compatible parts that you want and need at a competitive price. Now, it's time to put those parts together. Before we get started, let's take an inventory of the tools needed, as a minimum to build our computers. If you are not a tool person, do not worry. The tools needed to build a computer are pretty inexpensive. Below is a list of the 5 tools needed when building a computer:

SCREWDRIVER: Ensure that you have a Phillips screwdriver and a Flat head screwdriver. You will be using these items to mount components inside the case.

Phillips screwdriver

Flat head screwdriver

FLASHLIGHT: Your room may be well-lit, but sometimes it's difficult to see in small spaces inside the computer case, especially after you begin mounting components. I actually purchased a screwdriver with removable bits and a flashlight all together. It ran me around $10.

ANTISTATIC WRIST STRAP: These devices are used to safely discharge static build up. When getting one, look for the packaging to mention 1-megaohm resistor for added safety, to you.

MULTIMETER: You do not necessarily need this to build your computer, but you may need it whentroubleshooting a possible defective part. This is a good to have tool.

TWEEZERS: You will drop a screw into your computer. Sometimes they drop on the surface of your motherboard, behind the video card. This makes it difficult for you to reach your fingers in there to retrieve it. That's when the tweezers come in to play.

Of course, there are other tools that you may need. A power supply tester is always nice to have. Compressed Air in a can is another tool you may want to invest in. One other thing that you will need is a clean work space. You need some room when building a computer, so don't try and put it together on your kitchen counter, while your spouse is cooking. I use a 3' x 6' fold out table. This is my work station and on it I keep a monitor, keyboard and mouse, a tool-kit and a cup for screws.

So, there you have it. My next article will focus on safety. Then, my future articles will go into choosing the right components and how to also how to install them. I hope to see you again, soon.

What is lopper?

Loppers are a type of scissors used for pruning twigs and small branches, like secateurs with very long handles. They are the largest type of manual garden cutting tool.

Secateurs

They are usually operated with two hands, and with handles typically between 30 centimetres (12 in) & 91 centimetres (36 in) long to give good leverage. Some have telescopic handles which can be extended to a length of two metres, in order to increase leverage and to reach high branches on a tree. Loppers are mainly used for the pruning of tree branches with diameters less than 5 centimetres (2 in). Some of the newer lopper designs have a gear or compound lever system which increases the force applied to the blades, or a ratchet drive.

Construction

The main distinction among loppers is between bypass and anvil types. Bypass loppers operate like scissors, except that they generally only have one blade that moves past a jaw or hook that has an approximately square edge that is not typically sharpened and is usually concave or hook shaped in order keep branches from slipping out of the jaws. The jaws of bypass loppers may be straight, curved, or one curved with one straight. Anvil loppers have a single sharpened blade, with a straight or sometimes curved edge, that closes against a similarly contoured flat anvil like surface on the other side of the jaws, usually made of a softer metal than the blade.

Anvil loppers have the disadvantage of tending to crush rather than cut, sometimes leaving an untidy wound, more vulnerable to infection. Their main advantages are of relative strength and of being less likely to jam with fibrous material. Very hard or resilient branches can sometimes deflect a bypass lopper so that material either binds between the blades or even levers them apart, which can be dangerous both to the tool and the operator.

Both types of lopper generally have a sprung adjusting screw at the fulcrum, which can be used to tighten the blades as they loosen in use. With bypass loppers, it is also useful for releasing material jamming the blades. Anvil loppers usually have a screw for adjusting or detaching the plate, so that it can be moved to compensate for wear or replaced entirely.
