Engine Room Tools , , is a training manual that focuses on the correct use of tools aboard ship. It is noteworthy because it includes tools that are specific to the maritime trades. In this online version of the manual we have attempted to keep the flavor of the original layout while taking advantage of the Web's universal accessibility. Different browsers and fonts will cause the text to move, but the text will remain roughly where it is in the original manual.
In addition to errors we have attempted to preserve from the original, this text was captured by a combination of optical character recognition and human typist.
Each method creates errors that are compounded while encoding for the Web. PPlease report any typos, or particularly annoying layout issues with the Mail Feedback Form for correction. Richard Pekelney Webmaster. Sticht Co. This text is divided into three parts. Each part constitutes one lesson and is followed by its respective examination.
The correct procedure is to study Part 1, and complete and send in the examination for that part. Then study and complete Parts 2 and 3 in the same way. Except for certain special tools that are taken up later in connection with the equipment on which they are used, these lessons describe the hand tools commonly worked with in the engineering department of a ship, and explain certain precautions that should be taken in using and caring for such tools.
In order that the coverage will be as complete and helpful as possible, the lessons also include a description of some tools that might not be found aboard ship, but that would be encountered in shipyards, machine shops, and other places where maintenance and repair work is done.
The information in the lessons is extremely important to all who desire to be completely familiar with and well trained in the knowledge and uses of hand tools. It will aid the beginner, for example, to identify and locate the right tool for a job and help him to perform his work more efficiently. It should also contain much of interest to engineering personnel who have picked up their knowledge of tools more or less by chance as their work required various tools to be used.
Even engineers with long experience may gain valuable information that they had not known about previously. The Tools lessons will be found quite elementary in places, since they are prepared so as to be suitable for the beginning student, as just explained. They should be studied carefully, however, as this will enable all students to practice the art of study which they may not have been doing recently and will help them to master the more difficult engineering principles that follow in later lessons.
Good tools are essential if a mechanic is to do his best work quickly, properly and accurately. Good tools are carefully made, and must be handled properly if they are to work and last as intended. They cannot take rough usage. This is especially important aboard ship where it may be. In general, every tool should be given. Some tools should be kept close by the machine for which they are designed and on which they are used. Other tools must be stored in the tool room.
Tools should be cleaned after being used, should be oiled, in some cases, to prevent rust, and should then be returned to their respective places. When tools are taken care of systematically, it is much easier to find the tool needed. This is important, especially in an emergency. It is also possible to check more readily to see whether any tools are missing, and, if so, which ones they are.
A good mechanic will take care of his tools, as valuable time and possibly lives may depend on the accomplishment of a piece of work quickly and accurately. He will keep cutting tools sharp, grind them, if necessary, when through using them, and store them so that their edges will not be damaged or dulled by contact with each other or with other hard objects.
He will handle delicate measuring instruments with care, and will not keep them where they might be damaged by heavy tools. When work is being done, the necessary tools should be kept within easy reach, but not where they can fall and be damaged, or where they may fall and injure someone, as might occur from an upper level in the engine room. It is advisable to spread canvas along a grating, if tools are to be placed on it, or if work is being carried on where tools might drop and fall through it.
Openings in the engine or other equipment being worked on should be covered or plugged to prevent tools, nuts, bolts, etc. Such objects within the cylinder or crankcase of an engine, and not observed and removed before starting up, can cause considerable damage. Tools should never be placed on the finished parts of a machine, on the ways of a lathe, for example.
Sharp tools should not be carried in the pockets of clothing or left protruding from work benches, as they may tear or puncture objects with which they come in contact, including the workman. If a screwdriver is used as a prying tool, it may bend or break. If a chisel is used instead of a wrench, an important part of the machinery may be scarred or broken.
The way in which tools are handled, and the care given to them, indicates the quality of workmanship and the kind of engineering to be expected in your department. Several types of hammers are shown in Fig. The ball-peen hammer , often termed the machinist's hammer , is a very useful tool aboard ship.
The head of the hammer is made of hardened steel. The handle is of hickory or other hardwood. The flat portion of the head is called the face , and the other end is known as the peen, the latter being used for heading rivets and similar peening or drawing operations.
The hole for the handle is the eye. Ball-peen hammers are classed according to the weight of the head without the handle. They vary in size from 4 ounces to 2 pounds, three popular sizes being the 6-ounce for light work, the ounce for general utility, and the ounce for heavy work. The straight-peen hammer is used for spreading or drawing out metal in line with the handle, while the cross-peen hammer is used for the same operation at right angles with the handle.
The claw hammer is used for driving and pulling nails. Soft hammers are generally used where a steel hammer might mar or injure the work. The eye in the hammer head is made with a slight taper in both directions from the center. After the handle is inserted in the head, a steel wedge is driven into the end. This expands the taper of the handle in the eye and wedges the handle in both directions. If the wedge starts to come out, it should be driven in again.
If the wedge comes out and is lost, it must be replaced before continuing to use the hammer. Never work with a hammer having a loose head. A loose head will eventually fly off, and may injure someone. When using a hammer, it should be held near the end of the handle with the face of the hammer parallel to the work.
A grip just tight enough to control the blow is best. The correct way to hold a hammer is shown in Fig. Keep the hands and the hammer handle free from grease and oil, otherwise the hammer may slip from the grasp. It should also be remembered that oil or grease on the hammer face may cause it to slip off the work and lead to a painful bruise.
Do not ruin the hammer handle by using it for pounding or prying purposes. They can be procured in both single-face and double-face types, a double-face sledge being shown in Fig. The handles vary in length up to 36 inches. Several types of screwdrivers are shown in Fig. The standard screwdriver is used for most ordinary work and comes in a variety of sizes. The blade must have sharp corners and fit the slot in the screw closely; otherwise it is likely to slip and damage the slot.
It is also important that a screwdriver be held firmly against the screw to prevent it from slipping and injuring the worker or the work. The offset screwdriver makes work possible in tight corners where the straight type will not enter. It has one blade forged in line with the shank, and the other blade at right angles to the shank. The Phillips-type screwdriver is made with a specially shaped blade to fit Phillips-type cross-slot screws. The heads of these screws have two slots that cross in the center.
This checks the tendency of the screwdriver to slide out of the slot onto the finished surface of the work. The ratchet screwdriver is used to drive or remove small screws rapidly. Some screwdrivers have handles made of insulating material, and are useful when electrical work is being done. When a screwdriver with an insulated handle is not available, the handles of other screwdrivers can be insulated by wrapping them with tape. While the screwdriver shown in Fig. A heavy-duty screwdriver, also a special screw-holding screwdriver, are shown in Fig.
If the end of the blade is damaged, it can be made serviceable again by means of a grinding wheel. First grind the tip straight and at a right angle to the shank. After the tip is ground square, dress off from each face, a little at a time. Keep the faces parallel for a short distance or have them taper in a slight amount.
Never grind the faces so that they taper to a sharp edge at the tip. Do not use a screwdriver to check an electrical circuit where the amperage is high. The electrical current may be strong enough to form an arc and melt the screwdriver blade.
It is also bad practice to try to turn a screwdriver with a pair of pliers or to use it as a chisel. Do not hold work in the hand while using a screwdriver. If the blade slips, it can cause a bad cut. Hold the work in a vise, secure it with a clamp, or stand it firmly on a solid surface.
If such precautions are impossible, take care to have no part of your body in front of the screwdriver blade. That safety rule applies to any sharp or pointed tool. Side-cutting pliers are used principally for holding and bending thin material or for cutting wire.
They are used principally for holding and bending flat or round stock.

Have your CNC machines been behaving oddly lately? Do you notice a strange tick in their output, or in the way the machines are acting? A CNC machine is an electro-mechanical device used to manipulate and control machine-shop tools and devices using computer programming. In other words, controllers program the CNC machine to tell the machine shop tools what to do. The name CNC stands for computer numerical control. These machines used a data storage technique known as punched tape. Of course, this technique soon became obsolete, and the systems quickly turned to analog and then digital computer processing methods. The basic function of CNC machining is to take a blank piece of material, such as a block of plastic or a similar item, and transform it into a finished product. The CNC machine does this by telling the machine shop tool exactly how to move, and exactly what pieces of the material to cut away, to eventually arrive at the desired result.

There is much more to tools for electronics than just screwdrivers and pliers. While most of the common tools can be found at a local hardware or home improvement store, many are unique to the electronics industry. These specialized tools have evolved over many years, in some cases starting out as modified versions of common hardware store types, and in other cases designed from the outset to fulfill a specific need. If you need to use an integrated circuit IC with something like leads with hair-width spaces between the leads, then you should probably consider paying someone to mount it for you using screened solder paste and a reflow soldering system.
A chuck is a specialized type of clamp used to hold an object with radial symmetry , especially a cylinder. In drills and mills it holds the rotating tool whereas in lathes it holds the rotating workpiece. On a lathe the chuck is mounted on the spindle which rotates within the headstock.SEE VIDEO BY TOPIC: Pull Stud Clamp

Один из них, к ее удивлению, был адресом анонимного провайдера. Сьюзан открыла одно из старых входящих сообщений, и у нее тотчас же перехватило дыхание. ТО: NDAKOTAARA. ANON. ORG FROM: ETDOSH1SHA. EDU И далее текст сообщения: ГРОМАДНЫЙ ПРОГРЕСС. ЦИФРОВАЯ КРЕПОСТЬ ПОЧТИ ГОТОВА.
Ты хочешь сказать, что это уродливое дерьмовое колечко принадлежит. Глаза Беккера расширились. - Ты его .
Она достаточно хорошо знала Танкадо и знала, что он боготворил простоту. Его доказательства, его программы всегда отличали кристальная ясность и законченность. Необходимость убрать пробелы показалась ей странной.
Это была мелочь, но все же изъян, отсутствие чистоты - не этого она ожидала от Танкадо, наносящего свой коронный удар.
Она девушка Эдуардо, болван. Только тронь ее, и он тебя прикончит. ГЛАВА 56 Мидж Милкен в сердцах выскочила из своего кабинета и уединилась в комнате для заседаний, которая располагалась точно напротив.
Вот бы побывать здесь вместе со Сьюзан.
- Он даже не служит у. Стратмор был поражен до глубины души. Никто никогда не позволял себе говорить с заместителем директора АНБ в таком тоне. - Сьюзан, - проговорил он, стараясь сдержать раздражение, - в этом как раз все. Мне было нужно… Но тигрица уже изготовилась к прыжку.
Nimm deinen FuB weg! - прорычал немец. - Уберите ногу. Взгляд Беккера упал на пухлые пальцы мужчины. Никакого кольца. Я так близок к цели, - подумал .
Она подумала, не ошиблась ли где-то. Начала просматривать длинные строки символов на экране, пытаясь найти то, что вызвало задержку.
Хейл посматривал на нее с самодовольным видом.
