Basic Carpentry – On the Way to the Top

It seems everybody in the world knows a thing or two about basic carpentry. Or at least, the men do. For sure, these skills are rough, unrefined, and are limited to minor home repairs, replacements, nailing down noisy panels, and covering a hole or two. And the tools are rudimentary as well, from a hammer to a plane, a chisel, a couple of nails, and down to a handsaw. Moreover, selection of materials is not given much thought and consideration. Further, safety is thrown out of the window like excess wood cuts. But there are carpentry schools that provide classes on the basics and the proper approach to the craft. Like other activities, there is a right way to carpentry.


Basic carpentry skills are needed to properly carry out home repairs, minor additions, renovations, and other projects. Trade schools that teach the basics of carpentering normally discuss about introductory courses such as the manual and power tools and how to use them, read and interpret drawings and symbols, how to mark and measure, executing small projects, basic principles, and practical carpentry skills. Tutorial videos and e-books are also available to the weekend carpenter. Joinery works are some of the basic skills. From the very simple glued joint, to the half joints, the angular mitred joints, the dovetail, mortise and tenon, and others. A mark of a good carpenter knows which joint to use on a particular project.


Carpentry is a complex undertaking that only professional carpenters can perform. Simple carpentry works that are mostly confined to drilling, nailing, and fixing need only the basic tools. One would only depend on simple manual hand and power tools. These tools are steel framing squares, tape measures, handy power nailers, some chisels, chalk line, an electric drill, retractable utility knife, extension cords for power tools, a ladder, power cutters, circular saw, hardware, accessories, and others. Safety goggles, hand gloves, and steel-capped boots cover the safety end. All these items for light construction can fit in Carpenter kits and light trucks one can bring along in going to job sites.


Simple carpentry may be called light carpentry in that the size of the work can be managed by one or three people at most. And nearly all of these are related to carpentry jobs in homes, establishments, and interior works. They cover the work of constructing dry walls, fitting of door linings, cutting and fixing of architraves and skirting, dado rails, moldings, windows, kennels, play houses, and others. The proper handling of wood is basic at the same time very important to avoid wastage. Choosing the right kind of wood is also one of the basics. There are many types of wood, from soft to hardwood, that are chosen for work-specific purposes.


A basic carpentry course is a good start on the way to being a master carpenter. Probably the most practical and integral part of it is to accurately read and interpret architectural plans and schematic drawings and make functional multi-view sketches for actual execution. If one can’t correctly tell what and how the job entails and where, no matter his adeptness at his tools, then the individual is as good as a warehouseman. One very important facet is the understanding of electrical layouts and symbols to avoid electrical hazards and accidents. Proper analysis of drawing scales and transferring them to the job site is as important as knowing what the types of lines and their weights mean. There are numerous types of lines used in drawings that signify that something else is either above, below, or hidden.



Woodworking Carpentry Guide


When you have a project of woodworking in mind, you need to take some time to carefully plan as to how to implement this whole job. This is a very important step, for you to end up with a satisfying product and then you will want to go on and do something else in the future. If you do not plan, then all is lost, and you will get discouraged and want to give up the whole thing, and you don not want that to happen.


There is something to consider, some time before you approach doing this, to subscribe to some woodworking magazines first, as they have many different patterns in them, which would be a saving for you. Woodworkers who know what they are doing, have put these plans there for you to be helped along on your journey to success. They probably had some similar help, when they got started too. The internet has all kinds of sites too, with people who can give you some advice for your project. Take your time, and you will not be tempted to give up too easily later on.


They have plans for different projects, which you could check out, to see if any of them are similar to the one you had in mind. They are like a blue print for you to copy, or to change a little bit to suit your specific ideas, especially if you have some creative ability in you. Make sure that when you are checking the prices of the different woods and how much you will need, that you also do include any of the accessories, which will be required to finish this project. You would not want to get to the store and find that it is going to cost you a lot more than you budgeted for.


Skilled woodworkers will be modifying any design to suit their tastes. Most plans will include some directions that are right from scratch, the ground up, so to speak, so this is the blueprint for this whole project. You, as a beginner you should start something smaller, so you won’t take too long to complete it. The simple tools which you are starting out with will only be able to do something not quite so complicated anyway.


Considering how much skill you have, especially when you are a beginner, the project you pick, should be something not too difficult, or large either. You need to be able to complete it fairly fast, so you will not get too discouraged with it, before you can complete it. When you have put all your effort into getting the materials, then you need to see it to the end. Otherwise, you have wasted all your time, energy and your hard-earned money for nothing.


If you are having difficulty deciding what to do, you could always go and take some classes. This is a big help when you are just starting out. Your teacher can give you some good pointers, as they are skilled woodworkers, who at one time were where you are right now, so they would understand.

how do solar panels work

Understanding How Solar Panels Work. Solar panels take advantage of the sun’s energy, that is free and powerful. The energy transmitted by the sun in one hour is more than that used on the earth’s surface in one year. Solar panels convert this energy from the sun into electricity, making it a clean, simple and cost-effective power source. It is unlimited therefore dependable, unlike other sources.

How do solar panels work?

Solar panels are placed on roofs or open ground. These panels are usually frames made of solar photovoltaic cells. The photovoltaic cells are layers of polycrystalline or monocrystalline silicon. Silicon is a semi-conductor; it therefore has most properties of metals and insulators as well, making it a key component in the design of solar panels. The working concept of solar panels can be divided into a series steps.

i. Radiations from the sun hit the photovoltaic cells and are the effect from the cells produces a direct current (DC) energy.

ii. This Direct Current is converted to Alternating Current energy (AC) using an Inverter.

iii. The AC electricity produced is used to power appliances and storage batteries through the wiring system.

The Photovoltaic Effect.

In simple terms, the concept of a working of solar panel is allowing photons, or light particles, to knock free electrons in atoms, which generate electric flow. Photovoltaic cells (photovoltaic implies they can convert sunlight to electricity) are the basic working units of solar panels.

Every photovoltaic cell is a made up of two layers of a semi-conducting material, usually silicon. To work, the photovoltaic cells creates an electric field, that occurs due to separation of opposite charges, just as in magnetic fields. The resulting field is brought about by doping silicon with other materials such as phosphorous or boron that gives a negative or positive electrical charge on either side of the cell. Doping silicon enhances the flow of electrons when light photons hit the free electrons. The electron field created pushes electrons from the silicon junction. The electron flow moves as a steady electrical current from across the cells from one to the other. The sides of the PV cells have conductive metal plates that collect the electrons, transferring them to the wires. At this point, the electrons flow as in other sources of electricity. The entire process is the photovoltaic effect; where the light photons are converted into electricity (measured in voltage).

These photovoltaic cells are highly efficient and needs no maintenance apart from cleaning the cells at least once in a year. Some other types of solar power technology such as concentrated solar power (CSP) and solar thermal operate in a different way other than photovoltaic solar panels. However, they all use sunlight energy to either produce electricity or heat air and water.

AC to DC Conversion at the Inverter.

The electricity generated by solar cells is in the form of a direct current (DC). Home appliances are powered using an alternating current; therefore, an inverter is used for the DC to AC conversion. After conversion, it becomes a 120-volt electricity. The AC is connected to the local utility electricity distribution grid. This connection ensures that if more power is generated, it is transmitted back to the mains national electricity grid for redistribution to other parts hence generating some energy credit for you. The credit can be used to cater for energy costs for power provided by your local supplier when your solar power system is inactive. This reduces the monthly electric bill, and at times, you earn from it. The solar power inverter acts as part of the switching system controls solar power produced during the day and utility power supplied at night. Advanced inverters are used for data monitoring for your solar system performance alongside other grid integration services.

Solar Power Battery
The last component for solar power systems, however optional, is a set of batteries. In case the power generated is more than what the household can consume, the excess can be stored in a battery in the form of direct current electricity. This allows you to use solar energy even at night in case you are not connected to a local utility supplier. You can also use the stored power first before switching to utility. It is also useful when there is a blackout in your area.

Lowering Your Energy Costs Through Solar Panels.

Understanding how do solar panels work, in existence of an installed electricity service instead is the key to understanding the maximum utilization and economics of solar energy. Solar panel prices have also reduced in the recent years making this viable option to achieve greater economies of scale. Solar panels are therefore economical to use in any household, commercial or residential environment. Some other benefits you can gain from using solar panels include:

i. Solar energy is unlimited and reliable- The sun’s energy is free and unlimited, therefore a secure power source. Solar power provides consistent energy reliability in most parts of the world. The amount of sunlight received in different locations during a specific season can be easily projected, making use of solar panels more reliable.

ii. Guaranteed Performance- Solar energy prices do not hike compared to other electricity providers, and can be easily generated, therefore reducing bills. Solar panel manufacturers also provide a 20- to 25-year warranty or performance guarantee with most of their solar panels. As well, the solar industry standards guarantee over 80% performance even after the 25 years warranty period. Solar panels have a long lifespan, offering productivity up to 40 years. They also come with very low (to almost none) maintenance requirements.

iii. Solar panels provide energy independence – Installing solar panels ensure energy security boost and independence. Extensive use of solar energy leads to reduced costs of gas and oil imports.

iv. Solar Panels provide a clean and environment-friendly energy source – Unlike other energy sources such as fossil fuels that cause air pollution and eventually global warming, electricity from solar panels is clean with no adverse effects. Apart from the financial point of view on solar energy, it has many environmental benefits, the level of Carbon footprint can be lowered by replacing electricity from utility providers with clean energy from solar panels.
