How to install a sleeve stop and thimble set

However, you will get to learn through the process easily after one trial. You mightbreak one or two sleeves at first if you had never used the tools before.Pliers can only be used in case of low diameter cable.To create a proper and secure swage, very high pressure is needed.Hammer can be dangerous to use when you are swaging an electric wire/cable.When you are using a hammer to swage a cable, do not bash it too hard or it will break.But if you do not have one or do not want to buy, rather do without swaging tools, remember these following facts. п»ї Using a swage tool to swage cables is the best way.

Some Vital Things to Keep in Mind While Swaging Cable without Any Swage Tool If the cable is thicker enough, use the other methods to swage, otherwise,the performance might not be durable. You can only swage the narrow cables using pliers.Small nicks or scratchescan cause inaccurate measurements. Keep graduations and markings on all micrometers clean and legible.Store micrometers in separate containers provided by manufacturer.Coat metal parts of all micrometers with a light coat of oil to prevent rust.When the spindle and anvil come in contact with the workpiece, the measurement can be read directly from a digital display. TOTAL: 15,00mm = 1,50mm + 0,16mm = 16,66mmДigital micrometer is very accurate and does involve the computations needed by a standard micrometer. Then observe whether there is a half mm visible (minor divisions above datum line).3 x 0,50mm = 1,50mmДЇinally read the line on the thimble coinciding with the datum line. The thimble scale is marked in fifty equal divisions, figured in fives, so that each small division on the thimble represents 1/50 of 1/2mm which equals 1/100mm, which is 0,01mm.ДЇirst note the whole number of mm divisions on the barrel (major divisions below datum line). On the barrel the datum line is graduated with two sets of lines, the one below the datum reading in millimetres and the set above reading in half millimetres. One revolution of the spindle advances or withdraws the screw a distance equal to 0.5 mm. The same principle is applied in reading the metric graduated micrometer, but the following changes in graduations are used: The pitch of the micrometer screw is 0.5 mm. The line on the thimble that coincides with or has passed the revolution or long line in the barrel. Every fifth line on the thimble is numbered to read a measurement in thousandths of an inch. The beveled edge of the thimble is graduated into 25 parts, each line indicating 0.001 inch, or 0.025 inch covered by one complete and exact revolution of the thimble. The lines on the barrel conform to the pitch of the micrometer screw, each line indicating 0.025 inch, and each fourth line being numbered 1, 2, 3, and so forth. This means that one complete and exact revolution of the micrometer screw moves the spindle away from or toward the anvil exactly 1/40 or 0.025 inch. The micrometer screw has 40 threads per inch. Reading a micrometer is only a matter of reading the micrometer scale or counting the revolutions of the thimble and adding to this any fraction of a revolution. To overcome this problem the ratched stop is fitted and this drives the thimble through a ratchet device. If the force were to be excessive then it would be possible to overstress the frame thus causing permanent damage to the micrometer which would in turn lead to incorrect readings being obtained. Only a relatively slight pressure on the thimble can result in a considerable force being exerted between the two anvils.

The second refinement is the ratchet stop and this is a device placed on the end of the thimble. The micrometer can be set to a desired position and then locked. The first of these is the spindle lock which is a device which enables the spindle to be positively locked in any positions. Micrometers have been fitted with two refinements which are great help to the user. 001 of an inch.Дepth micrometers are used to measure depths to an accuracy of. Inside micrometers are used to measure an inside diameter to an accuracy of. Outside micrometers are used to measure an outside distance or diameter to an accuracy of. There are three types of micrometers which are commonly used: the outside micrometer, the inside micrometer, and the depth micrometer. The spindle carries a graduated thimble which turns at one with it. The bore of the barrel (sleeve) is threaded and a spindle screws into the bore. The micrometer consist of a semicircular frame having a cylidrical extension, the barrel (sleeve), at its right end and a hardened anvil at the other end.
