Carpentry Training â For Budding Carpenters and Hobbyists
Carpentry, as a craft, is working on a piece of wood either for constructing new houses or hammering out a fine piece of ornamental decoration in furniture, interior design, doors, and cabinets among others. Â As a line of work or for carpentry projects during the weekends, it can be very rewarding. Carpentry training is a must for would-be carpenters. A complement of the right tools makes it simple and at the same time very challenging. There is always a need for a highly skilled wood smith. Some carpenters specialize in new or restoration construction while others concentrate in furniture, cabinets, doors, and finishing.
Carpenters are generally considered to be all-around and knowledgeable, if not skilled, in most facets of construction. They know a bit of masonry, tin smithery, and metal works. They are relied upon to erect scaffoldings. It is possible to be a rough carpenter and at the same time a finishing carpenter. They also make the floors, roofs, walls, and partitions and the necessary framing for items that do not require concrete. As a carpenter, one needs to be skilled at all kinds of tools, from manual to the portable and stationary power tools. Squares, hammers, and chisels are examples of manual tools. The power saw and drills are some of the power tools. One should also be able to read architectural plans, symbols, and construction drawings. Further, it is important to interpret them according to work specifications. Also, a good carpenter never underestimates the consequence of safety.
There are two main fields in carpentering, rough and finishing carpentry. Rough carpentry involves the unseen part of a house. This is the field that is actually involved in construction and building. Tradesmen in this field prepare formworks and bracings for reinforced concrete like columns, stairs, floors, walls, beams, girders, and, of course, for the footings and foundation. To form concrete structures, wooden formworks need to be strong and sturdy, but not too rigid in that it should take the weight of fresh concrete. Needless to say, the surface exposed to the concrete has to be clean and spotless. They also handle heavy framing for some structures that require hardy framing.
The work of finishing carpenters usually covers the visible areas and items that define the space. They produce drywall partitions, simple to complexly designed ceilings, moldings, manufacture and installation of doors and windows, flooring, counters, and cabinets. Doors, windows, and cabinetry have become specializations in themselves and have become distinct trades. When orders for the doors, windows, counters, and cabinets have arrived, it is they who finish the installation. Subjects in carpentry training comprise virtually all aspects of the craft, from materials, estimation, costing, to the tools and how to use them to create carpentry works.
Carpentry training is offered as a course by many colleges and institutions. Entering carpentry school at qualified training centers may have the slight advantage because it is more organized and certifications are handed out. Or it may be that a person is apprenticed to a skilled carpenter. Either way, exposure and adeptness in handling the material and the tools are keys to earning vocational qualifications from government certifying agencies. Training may also be done at home for the hobbyist and the weekend carpenter with do-it-yourself CD’s, videos, and e-books. Modules are available for simple projects, to repairs, how-to’s, and others. Most training programs cover everything from the ground up to the roof and everything in between including what needs to be done and how it is done.

confused,Hammer&feather on moon ?
can anyone please explain why on the video of a hammer and feather getting dropped on the moon,,,how did they both fall at same speed and time?? they talk about it as if there is NO gravity,but there on the moon ??,so there saying no matter the size weight shape,every thing will fall same speed,so the luna rover and landing module is as heavy as the hammer and feather ??so you would need the force to lift a hammer off moon surface to get the people home ??
WAKE UP AND SEE WHAT IS ASKED,AND NOT RANT ON,THERE SAYING IT IS ZERO FOR THAT TO HAPPEN BUT IT IS SUPOSED TO BE ON MOON 1/6 NOT ZERO,HAVE YOU SEEN THE VIDEOS ON MOON WITH VIZOR UP?? BURN YOUR EYSE OUT IN SEC ANY ONE HAD ARKE EYE ?? LOL
You seem upset.
I would have to guess that it is due to frustration from your answerers misunderstanding your question.
Please don't blame them.
Your question is mostly incoherent.
It's only a guess, you understand, but I believe you are asking about the significance of the Hammer/Feather demonstration performed by Cmmr. Scott of Apollo 15?
Principally, the experiment meant to grossly demonstrate two things:
1) Galileo's 17th century experiment showing that two objects with different masses will fall at the same rate, even on the Moon, where gravity is about 1/6th of Earth.
2) Galileo was unable to get the same results using a very lightweight object (a feather), surmising that air resistance was a factor. On the Moon, where it is a near perfect vacuum, air resistance would NOT be a factor, so a very light object (a feather) was dropped at the same time as a heavy object (a hammer).
"so the luna rover and landing module is as heavy as the hammer and feather ?" Here you seem to be using Aristotelian physics, instead of Newtonian... which is actually a good thing, as the whole demonstration was meant to show Aristotelian physics was incorrect.
"so you would need the force to lift a hammer off moon surface to get the people home ?" No, sir... one of the other laws of Newtonian physics is that the force required to move an object is proportional to its mass. Perhaps where your confusion lies is the assumption that the force on the feather was EQUAL to the force on the hammer? It was not. Their accelerations were equal. The gravitational field of the Moon acts on the feather exactly the same as the hammer, but as the feather has less mass it requires less force to move it.
The opposite is equally true, though I hesitate to mention it, as it may just increase your confusion... but the force on the Moon by the feather is equal to the force of the feather on the Moon.
