Design and Construction of a Wooden Bookshelf

Construction of a Wooden Bookshelf

ABSTRACT

A bookshelf is a component fabricated to store or package books, files, and other important documents.

The main aim of constructing this project is to produce a wooden bookshelf that will provide a lasting solution to the problem facing libraries, offices, churches, and homes in packaging and storing book items and other items.

In search of storage facilities for books, and other important documents in libraries, offices, etc, a concept to produce durable bookshelf was initiated. Therefore, the construction of this shelf will help the prospected user(s) to be packaging their documents well and safely. There are different kinds of engineering materials that could be used in this type of construction apart from wood. These are metal, plastic, and glass.

The construction was facilitated by some simple machines (tools) such as hammer, saw, tape, scriber, jack plane, sandpaper, sprayer, and materials such as nails, hinges, and gums. Different operations were performed sequentially to realize the finished product (bookshelf). Such processes are: making out, cutting/sewing; planning/smoothening; grooving and sinking (where necessary); joining; spraying.

Mahogany wood was utilized in the construction. The wood was cut with sawing machine having measured it with tape to rescuer the desired measurements thus: 48 inches height: 42 inches Length: 12 inches breadth. It was then smoothened to give a nice outlook.
With gum, the skeleton was formed before nailing. The skeleton was so formed before partitioning so that it would support and create reinforcement to the shelf and make it stand firm at the expected position while nailing and fixing the doors with hinges.
As sequent to this, it was appropriately nailed and gum was blended with sawdust to smoothen rough and gapped places on the shelf before sandpaper and sprayed with sprayer.

Conclusively, the glass doors were fixed which embellished the job exceedingly.

As a matter f fact, the construction was designed to meet the requirement of the Nigerian Standard Organization (NSO) in the construction of bookshelf. This is for the fact that the materials used were high-quality ones. Not only for these reasons but the standard measurement was also employed as indicated above.

It is necessary here to summarize the cost of the project as given in detail in the recommendation part of this write-up. Thus, the cost of material was nine thousand nine hundred and severity naira (N9,970.00). Running cost was one thousand and two hundred nairas (1,200.00) whereas workmanship was three thousand eight hundred and thirty naira (N3,830.00) to total the sum of fifteen thousand naira (N15,000.00).

CHAPTER ONE

INTRODUCTION

Two important questions require an answer before an engineering material is chosen for any purpose. They are, what function does the component have to perform, what are the essential requirements of the component so that it can fulfill those functions. The engineering materials can be broadly grouped into two main categories metals and wood. These materials are used for different purposes either as individual materials or a combination of materials for a certain requirement of the desired finished product.

Hence, the construction of an engineering component like the workshop material can serve the purpose for which the bookshelf is fabricated. Thus a wood, specifically mild wood is chosen for this project due to several properties as regards to the analysis of its function and requirements which are considered based on common characteristics as follows: center of mechanical properties such as strength, hardness, fatigue resistance, etc. Certain behavior in specific environment eg. Corrosion-free, ability to be formed or fabricated to desired shape and dimension, as well as its cost factor.

However, there can be other requirements which though not essential, are desirable for instance the surface finished of the component must be alternative, which might be accomplished by painting or spraying using a quality paint or spray that resists the certain environmental impact of behaviors.

Nevertheless, the choice of fabrication process depends on several factors possibly:- the quantity of the items required. The dimensional accuracy. The surface finished required the size of the item. The cost factors, etc.

As a result of this consideration, the method chosen for the workshop bookshelf fabrication is a simple wood joining process, which incorporates: cutting, marking out, nailing, spraying, and various fastening system:

Furthermore, the basic components and properties, fabrication factors, and also cost factor of the basic material (fine wood) for workshop bookshelf construction are fully illustrated in the subsequent sectarian. Other materials which are employed for specific purposes are a saw, hammer, nails, scriber, tape, gum, sprayer, handle and key, down drawer, and glasses.

This writes up hence has the primary objectives of guiding and providing students, designers on fabrication engineers with the idea of the property requirement of a material or the construction of a workshop bookshelf on regards to making a prudent choice to enable one to achieve the desired component with adequate services requirement and durability.

CHEMICAL PROPERTIES OF HARDWOOD

Corrosion Resistance: This is the ability of the mild hardwood to resist corrosion in a chemical reaction of a material with air in the presence of a mixture and chemicals. Corrosion makes the materials fade quickly leading to failure. But by the ability of mild wood to resist this chemical reaction makes it desirable for the workshop bookshelf fabrication where it gives optimum resistance to corrosion attack.

FABRICATION FACTOR

Fabrication forming or area process of making the wood into the desired shape, and retains its properties. As indicated earlier, the choice of forming or fabrication process depends on several factors more importantly the cost of the process.

In general, this material (wildwood) and the fabrication method are chosen based on the lowest total cost ie fabrication, and material cost which is consistent with the required level of performance for the component.

Also, the commercial form of supply of materials eg wood sheet, etc which affects the used together with the materials affects the choice of material and fabrication process.

Thus, of the two main methods of producing a component, namely forming and wood joining, the latter is preferred because of the various involvements with other materials as well as for specification and dimension amongst other factors which are no doubt sort of cover, a wood sheet with a higher thickness was chosen for it so that it can withstand attacks by insects and can accept a strong treatment which might be given to it.

The frame is the skeleton of the whole system, this frame was first erected together before the sheets of the sides, back, and partition which withstand the stress that will be exerted on it by the sheet and the load.

OBJECTIVES OF THE PROJECT

The objectives of the project cannot be over-emphasized since, by its name, the uses are remarkable.

Nevertheless, the workshop bookshelf helps the users to pack their books at the end of their use. This means that it serves as a preservation unit. With the availability of the bookshelf, it is easy for uses to get any documents or books they want since they are stored in the book shaft in the unit. Apart from the importance and utilization of the book shaft, the project generally would serve as a guide to technicians and students who embarks on research and project reviews.
